Brief Introduction of Shaping Shaping and Sand Making Effect of VSI Sand Making Machine

VSI series of sand making machine crushing process is very simple, involving several different broken away. In essence it is also a high-speed rock centrifuge. There are several crushing processes in the sand making machine - the impact and mutual friction can break the rock. Between the crushing chamber and the particles in the turntable, a high-intensity collision occurs between the particles and the counterattack plate, thereby breaking the rock.
VSI sand making machine
In the process of crushing and grinding stone stone, continue to add rock liner. First with the rebound after the free fall of another part of the material to impact, and then together to the impact of the material lining (stone stone) or counterattack block (stone black), was rebounded obliquely impact to the top of the vortex chamber, but also to change its movement direction, Deflected downward movement, but also with the material from the impeller flow out of the impact of the formation of a continuous material curtain. In this way, a piece of material in the vortex crushing chamber by two to several times the impact of impact, friction and grinding crushing effect. The broken material is discharged from the lower discharge port. In the crushing chamber, there is a collision between the particles, until the energy shortage and fall, leaving the crushing chamber. Rock in the crushing chamber to stay in the general time in 5 ~ 20s.
VSI sand making machine using advanced selective crushing and cleavage crushing principle, directly on the material to exert sufficient kinetic energy, and through the impact of kinetic energy to overcome the broken material required to break the material. Material along its natural texture surface, cleavage surface fracture, grain shape is good, their own low consumption. Is the first choice for sand and gravel.

Several types of construction waste crusher

Due to the different construction materials and the nature of the material is also very different, in order to meet the needs of practical work, construction waste crusher type is varied. The construction waste crusher used in the construction waste disposal may be distinguished by its work object or structure and working principle.
First, according to the job object can be divided into the following three:
1, coarse crusher for the first large pieces of material broken, construction waste crushing machinery can handle the maximum block diameter of more than lm, mainly crushing method to crush. Crushing ratio is not large, generally less than 6.
2, the size of the material processed in the crusher is usually not more than 350mm, mainly crushing or crushing method for crushing. Because this type of crusher usually includes crushing operations, including crushing is relatively large, generally 3 to 20, individual up to 30 or more.
3, fine grinding machine for grinding particle size of 2 ~ 60mm material particles, the product size does not exceed 0.1 ~ 0.3mm, the smallest up to 0.1mm below the crushing ratio of more than 1000.
Second, in accordance with the structure and working principle of the different, commonly used crusher has the following main types:
1, jaw crusher It is to rely on the activities of the jaw to do cyclical reciprocating motion, will be added to the two jaws between the material crushed.
2, cone crusher outer cone is fixed, the construction waste crusher equipment cone is eccentric shaft (or eccentric sleeve) with eccentric rotation, the material between the two cone by the pressure and bending force and broken.
3, the roller crusher material in two parallel to each other and the direction of rotation between the rollers were squeezed (light roller), or by extrusion splitting (tooth roller) and broken. Such as the number of revolutions of the two rollers there are some grinding effect.
4, hammer crusher block by the impact of high-speed rotating hammer and the block itself to high-speed fixed to the liner on the impact and broken.
5, wheel mill material in the disk was rotating cylindrical grinding wheel crushed and ground.
In addition to the above mechanical crushing method, the current has been broken with electricity, its working principle is: in the high-voltage circuit, put a pair of appropriate gap metal needle, after the high voltage, the pulse of high pressure spark discharge , Resulting in ultra-high voltage, leaving the material in the water to break. In addition, there are ultrasonic and low sound broken.

Effectively improve the performance of Impact crusher

Machine vibration strong cause analysis:
Equipment running a strong vibration and noise, the rotor bearing temperature increased rapidly, resulting in bearing burned, the Impact crusher can not function properly. As the hammer often used castings, casting and processing of low precision, the quality of the plate hammer difference between the larger, if not taken when the assembly of certain measures, will cause the rotor quality imbalance. And because the rotor of the larger quality, high rotation speed. Unbalanced will produce a strong polarization, so that the bearing heated. Even burn out.
Even when the replacement of the hammer to take effective measures, the rotor in line with the balance requirements, but the machine after a period of time, due to the uneven hammer wear and tear, will lead to uneven rotor vibration.
Measures to avoid machine vibration is to keep the rotor balance. If the vibration of the machine in the production is aggravated, it should be stopped to check the wear of the plate hammer. If the plate hammer wear does not reach the wear limit, it should be changed edge or transposition, so that the rotor to restore balance; if the plate hammer wear has reached the wear limit, it should be replaced.
Plate hammer wear serious cause analysis:
Plate hammer wear is the main failure form of the Impact crusher. General plate hammer short life, consumption, need to reserve a large number of spare parts in order to maintain normal production, high production costs.
Plate hammer short life of the reasons there are two: First, the choice of improper plate hammer material. Now the anti-crusher material for the high-chromium cast iron, wear resistance is good. Second, the choice of improper plate hammer structure, the same conditions in the material under the effective wear and tear, wear a lot of plate hammer natural long life.
The treatment measures can improve the service life of the plate hammer from the scientific selection of the material of the plate hammer and the optimization of the structure of the plate hammer. Plate hammer selection, should choose some good wear resistance materials, such as high chromium cast iron and low carbon alloy steel.

How to carry out the full grinding work

ultrafine milling machine, such machinery and equipment in the use of the process, there will always be more or less, or large or small problems occur, so that users occasionally come to headache brain heat. Immediately into the heat of the time, Shanghai SBM today for you to solve the ultrafine mill how to fully grinding the work of this problem:
Whether it is already invested or is expected to invest in the customer, all know a complete ultrafine milling machine production line, its reasonable configuration will have a strong force in the work of grinding, according to a certain Of the grinding ratio to carry out, which, the number of materials, how much power regulation, fineness of the number of production, will have no small impact. Then we all know how to match the ratio, in order to allow ultrafine milling machine at work to play a higher level of it?
The increase in the amount of feed to the ultrafine mill and the processing of the grinding chamber has a great impact on its working efficiency. Before we pay close attention to the loading of ultrafine milling machine, neither too much nor too little. The amount of input is too small, the output value will be reduced accordingly, the production value on the do not; too much material, the remaining space inside the cylinder, grinding the impact of the body to reduce the equipment prone to minor problems.
Secondly, in the grinding process of ultrafine milling machine, we have to match the power ratio with the appropriate proportion. Production power and mill running ratio should be appropriate, if the power is too small material dispersion is poor, the grinding body of the movement resistance increases, the grinding effect is not achieved. On the contrary, the power is too small, indirectly increase the direct impact between the grinding body, so that the loss of energy, increasing the grinding of each other wear. So in order to allow ultrafine milling machine material clearance, we will generally in strict accordance with the proportion to carry out. But also in strict accordance with the proportion to carry out, so that both improve the efficiency, but also to ensure that the mill is not subject to excessive wear and tear.
At the same time, here to introduce the ultrafine mill configuration in the "a dark horse" - quality liner. Lining is the safety factor that can improve the operation of the mill. ultrafine milling machine in the grinding process, it is inevitable mixed with hard materials, if the material hardness is too large, then the mill itself is a hazard, serious Of the time, will have an impact on the wear and tear of the mill itself.
Therefore, for the purpose of protecting the ultrafine milling machine, we have to experiment, improve the quality of liner, thereby enhancing the safety factor. Why install linings? In fact, the reason is very simple. Because the thickness of the liner than the ultrafine milling machine combined with two, can effectively avoid the relatively hard materials on the ultrafine milling machine hazards, but also to ensure the production of life, with a liner, you need not Worry, and be as safe as possible.

Structural Analysis of Mobile Construction waste crusher


In the initial treatment of garbage generated in the building, because many buildings are not concentrated, resulting in a lot of construction waste is not enough concentration. Therefore, when setting up the factory, the dispersion of construction waste also need to be considered, so as to improve the processing efficiency. Otherwise it will take a long distance and time to transport, so not only increase the cost of transport, but also lead to secondary pollution. So the mobile recycled aggregate production model will become the future Construction waste crusher equipment, an important direction of development. In the scene of the construction of construction waste, people will be able to initially deal with these garbage. And then to the aggregate depth processing center to transport the processed recycled aggregate and then complete the corresponding treatment. This will not only reduce transportation costs, but also reduce its impact on the environment.
By the crusher, screening system, debris sorting device, transmission mechanism and vibration feeder, self-running function together constitute a mobile building garbage crusher. And, the mobile organization is configured, it can be said that the production line is moving,
(1) crusher
In the mobile crushing station, the crusher is the core component, crushing the construction waste is its main task. The hardness of the material is the main feature of construction waste, low viscosity, there is no high demand for water content, therefore, must ensure that the stone crushing requirements of the equipment will be in the construction waste recycling mobile crusher is used. In order to improve the performance of recycled aggregate, it should be broken out of granular materials, effectively reduce the sheet material content, and to ensure that the particles can be evenly distributed. Therefore, be sure to follow the appropriate standards and scope to control the crusher performance, efficiency and material size.
(2) Screening system
In order to produce high-quality recycled aggregate, if it is difficult to complete a broken in accordance with the requirements, it is necessary to double the broken, which requires the addition of screening system, in the larger particles of the concrete block screening, and then to the crusher In the delivery, again crushing treatment to ensure that the effective disposal of construction waste.
(3) debris sorting device
Many debris is present in the construction waste, in particular, there are a lot of scrap wire, waste steel material exists in the reinforced concrete, therefore, need to set a debris sorting device to the mobile crusher, the waste wire, The impact of recycled aggregate properties is reduced.
(4) vibration feeding equipment
If the crusher into the construction of garbage directly, this will give a great impact on the crusher, if a long time to do so, it will lead to its uneven force, the normal operation of the equipment impact. Therefore, it is necessary to install a vibrating feeder before the crusher. The biggest advantage of the vibrating feeder is the ability to evenly feed. After the vibration of the material, move forward, slowly into the crusher before entering, if the Construction waste crusher, will fall in the gap between the bar, so as to play the role of screening.
(5) self-walking device
Tire-type and crawler-type walking mechanism is the mobile crushing station in two important walking agencies. Tire-type walking mechanism to facilitate the ordinary road walking, turning radius is small, can be stationed quickly in the site, equipment, high flexibility and save time. Crawler-type walking mechanism, able to walk smoothly, with a lower ground pressure, can effectively adapt to wetlands and mountain environments. Usually on the full hydraulic drive system applications, it is highly reliable, large driving force.

Raymond Mill system running its own software generated by the coarse grinding and grinding system code, the program automatically completed Raymond rough rough process, feed rate is set to 80mm / min. After the rough grinding is completed, run the finishing procedure according to the allowance, set the speed to 40mm / min. Refinement of Raymond's surface before each refinement to remove abrasive powder. Dressing process as shown, after the rest of the Raymond grinding surface is more detailed, no obvious defects.
In the grinding process, the formation of high temperature in the grinding area, the raymond mill wear, parts surface integrity deterioration, parts processing accuracy is not easy to control, it must be grinding fluid into the grinding area, reducing the grinding temperature. Grinding fluid not only lubrication and cooling effect, but also the role of washing and rust. Thus, the correct application of the grinding fluid is important for successful grinding.
F-SYN 100, which is a water-soluble coolant without mineral oil, is mainly used for grinding operations and is particularly suitable for forming grinding. When the workpiece requires low foaming and high visibility processing conditions, the product is more suitable. It has the following advantages: Transparent solution, high stability, low spill loss, coolant Even at higher pressure the level of foam is also very low, good grinding disc flushing effect, grinding solution life is very long, good skin compatibility Sex, good filterability, medium odor, the impact of small residue.
Forming milling process preparation: the internal gear forming Raymond Mill is the use of Siemens 802C Raymond Mill system, Raymond Mill system programming methods are mainly two ways: one is the computer programming, it can be online programming Can also be programmed offline, through the use of special software on the computer to prepare the workpiece program, and then through the RS232 interface into the Raymond Mill system machine saved in the processing program memory, the processing can be transferred to achieve automatic processing: the other is manually entered Programming, that is, by the programmer from the machine Raymond Mill system operating panel manual input processing procedures. As the internal gear forming grinding process is relatively simple, easy programming, we use manual input programming. According to the principle of the forming process of the raymond mill grinding machine, the parameters of the gear to be machined and the machining precision requirements, the logic block diagram of the machining gears is drawn first. In order to better ensure the symmetry of the left and right tooth surface, with the shape of the Raymond grinding surface grinding grinding gear on the left and right two tooth surface, in a repair after grinding the left and right two tooth surface is conducive to Guaranteed size consistency. In the process of grinding, if found Raymond mill wear, to timely use of the diamond wheel for Raymond grinding dressing.

Inspection of working efficiency of ultrafine grinding machine

In the use of mine resources, in addition to a small number of minerals can not use the commonly used equipment processing, 85% of the ore resources are through the ultrafine mill processing, with its physical state of the powder posture to attack the market, And get their own proprietary performance. So the production efficiency of grinding operations is the focus of the production of manufacturers, then, how to detect ultrafine grinding machine is "lazy" it?

First, the detection of operating rate, that is, ultrafine grinding machine working time ratio:

It refers to the actual working hours of the equipment for a month or a year as a percentage of the number of hours. The operation rate of the ultrafine mill reflects its technical status, which reflects the management level of the staff. Which can also expose and analyze the reasons for the abnormal operation of the milling operations, to take effective measures to improve. Improve the operation rate of ultrafine grinding machine equipment also increased the production capacity of milling workshop.

Second, the production capacity:

Production capacity of ultrafine grinding machine, including production capacity, the use of coefficient, the specific size of the utilization factor. Only when the equipment model, specifications, ore nature, to the ore particle size and product size and the same provisions, the ultrafine grinding capacity of the mill can be more concise review of the work situation. The use of the coefficient can only be in the ore particle size, product size are similar conditions, in order to more truly reflect the nature of the ore and the various conditions of milling. Specific grain size utilization coefficient can be more realistic reflection of the work, you can compare the different specifications, different particle size and product size of the work under the production capacity.

Third, the fineness and efficiency of milling:

Finished fineness is the production of ultrafine mill, the daily inspection of another quality indicators. The fineness of the powder is usually sieved with the "sieve" of the "standard sieve" and is expressed as a percentage of the total amount of the product through the sieve (ie, the sieving rate). The higher the sieving rate, the finer the product The more production. Unit power consumption productivity can be more realistic from the energy point of view reflects the ultrafine grinding machine work, therefore, can be linked to productivity and productivity evaluation equipment work.
