We only know that the sand making machine can also be used in the sand and gravel production line to make the sand and gravel production line better. So how does the sand making machine work in the sand and gravel production line to assist the sandstone production line? We don't seem to be very clear. Today, let's take a look at how the sand making machine performs in the sandstone production line. Is it really as good as people's legends?

In the gravel production line, the bulk raw ore through silo is reasonably sent to the jaw crusher for coarse crushing by the vibrating feeder; the coarsely crushed stone is sent to the sand making machine by a belt conveyor or other conveyor for further processing. Broken, that is, finely crushed; the finely crushed stone is sent to the vibrating screen by a belt conveyor for screening, and several stones of different specifications are screened: the stone that meets the particle size requirement is sent by the finished belt conveyor to the finished material pile; The required stones are returned to the sand making machine by the belt conveyor for re-crushing, thereby forming a closed circuit multiple cycles. The finished product size can be combined and graded according to requirements. In addition, in order to protect the environment, an auxiliary dust removal device can also be provided.

Why is the sand making machine working well in the sandstone production line? This is definitely an advantage in some aspects. For example, the sand making machine has a high degree of automation, a large crushing ratio, high production efficiency, and large processing capacity. The broken product has a cubic shape, a low needle-like content, and no internal cracks. The welding strength is high; the sand making machine equipment is easy to maintain and maintain, and the wearing parts are currently used in domestic high-strength wear-resistant materials, with low loss, long service life, and can bring considerable economic benefits to customers.

First, it is impacted and broken by a part of the material falling from the periphery of the distributor, and then impacted together with the vortex The material lining on the cavity rebounds by the material lining, impacts obliquely upward to the top of the vortex chamber, changes its direction of motion, deflects downward, and the material emitted from the impeller runner forms a continuous material curtain. Such a material is subjected to two or even multiple chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge opening. During the whole crushing process, the materials are crushed and broken by themselves, and are not in direct contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces pollution and prolongs mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution. The world today advocates sustainable development, and we must do everything possible to reduce environmental pollution. Therefore, the river pebble sand making machine and sand making production line also adhere to the principle of green health and respond to the country's call to minimize pollution.

When processing stone or mine resources, a large amount of dust is generated, the pollution to the environment is quite large, and the health hazard to humans is also great, so the user must solve the large amount of dust generated in the sand production line equipment. Perform effective processing.

We can solve the environmental pollution and worker health hazards of the sand making machine in the stone crushing production line equipment from the following aspects.

1. The dust at the corner of the belt conveyor is restricted by the site conditions. The chute and the dust hood cannot be changed. The dust removal process is arranged in a form that makes the dust hood in a micro-negative pressure state to eliminate the dust of the belt conveyor.

2. Strengthen the management of dust removal equipment, regularly check the airtight cover, and find problems in a timely manner. Carry out target management assessment on the dust emission of the post environment and bag filter, regularly conduct dust monitoring, use the economic lever to mobilize the work enthusiasm of the post personnel, improve the maintenance level of the dust removal equipment, and greatly reduce the dust pollution.

3. Improve the process layout of the bag filter, arrange the dust collector of the sand machine according to the direction of the belt machine; transform the standard type ash bucket of the bag filter into a double ash bucket structure, thus canceling one screw conveyor, Raising the bag filter is beneficial to the arrangement of the air inlet pipe (the angle of the air duct is large); the air inlet box is arranged at the air inlet to make the dust of the sand inlet of the sand making machine directly enter the air inlet box of the dust collector, saving the elbow Reduces system resistance and improves dust collection efficiency. The ash bucket lock wind adopts a single-layer flap valve, which eliminates the grid wheel feeder and its motor, reduces secondary dust and improves dust removal effect.

After the improvement, the degree of pollution of the sand making machine in the stone production line equipment is relatively reduced. In addition, the maintenance and cleaning of the equipment is also very important.

The importance of the sand making machine in the sand production line is self-evident. It plays an important role. When the sand making line is in progress, the sand making machine has problems, just like people lose in the normal life. Oxygen, life can not continue, and the sand production line is also the same, so there are problems with the sand making machine, we have to be calm, look for professionals to view and repair, the following Shanghai ZENITH introduces several frequently occurring problems and solutions.

1. The bearing load of the sand making machine is too large: check the load. Under the correct load conditions, control is within a reasonable range.

2, the sand machine bearing torque load of the enemy invasion, inflow: improved rust seals, downtime. Improved surface finish for paired rolling parts. The dark side is shown, the dark surface has a slight abrasion depth of 5-10M micro-cracks and the small opening fractures are installed from the surface inward over a wide range. Improved sealing device.

3. Improper lubricant: Use a lubricant of appropriate viscosity to improve lubrication. The surface finish of the sanding machine bearing paired rolling parts is poor. Foreign matter enters the lubricant. Choose the right lubricant.

4. The bearing clearance is not suitable. The bearing housing is of poor precision and the rigidity of the bearing housing is uneven: check the accuracy of the shaft and bearing housing. Check the gap.

5, sand making machine bearing shaft rust, erosion, wear and indentation points check the accuracy of the shaft and housing. The inner ring of the ball bearing load of the ball press rotates, and the rolling fatigue of the raceway surface of the outer ring or the rolling surface is flaky. The so-called card injury produces a slight burn on the sliding surface that summarizes the damage caused by surface damage. The surface roughness caused by the lubricating oil is poor. Stripping the lubricant is not appropriate, improving the lubricant and lubrication methods.

For mining machinery, there are certain wears in the processing of various ores, and these wears will cause their failures, such as the phenomenon of rocking when the river pebble sanding machine is working, here It is to introduce the reasons for the three aspects of this phenomenon.

The first reason is that one of the important parts of the river pebble sand making machine is the impeller. If there is obstruction in the impeller flow path, the feeding will be uneven and the body will swing too much. The solution at this time is to put the impeller on the flow path. Obstruction

The second reason is that if the river pebble sand making machine is used, the phenomenon that the feed particle size is too large will cause the swinging condition to occur. Of course, the feed particle size should not be too small or the crushing is insufficient. Production requirements, which is why the river pebble sand making machine is very strict with the feed particle size requirements;

The third reason is that when the river pebble sand making machine is used, the wear phenomenon of internal parts is inevitable. One of them is the wear phenomenon of the wearing parts on the impeller. If the wear is serious, it will cause the unstable operation of the equipment to sway. This time The solution is to replace the worn consumables so that the operation of the equipment reaches equilibrium;

This paper mainly introduces the three causes caused by the rocking phenomenon of the river pebble sand making machine. The above is a detailed introduction to these reasons, and the solution is given. Only by solving the phenomenon of the machine swinging, the production can be made. Smooth progress.

Generally speaking, there are many factors affecting the production capacity of the sand making machine. Generally speaking, there are five factors in this way. I will describe the factors in these aspects and propose corresponding solutions.

1. The hardness of the material. The harder the material is, the more difficult it is to break, and the more severe the wear on the equipment. The speed of sand making is slow, of course, the sand making ability is small. This requires us to be moderate in the choice of materials.

2. The composition of the material, the more fine powder contained in the material before sand making, the more the sand is affected, because these fine powders tend to adhere and affect the transportation. Therefore, materials with a high content of fine powder should be sieved once in advance. The fine powder should be filtered out of the material as much as possible to avoid affecting the normal operation of the sand making equipment.

3. The fineness of the material after sand making and the fineness requirement are high, that is, the finer the material required for sand making, the smaller the sand making ability. In this respect, depending on the specific requirements of the concentrator, if there is no special requirement, the fineness of the material is generally set to medium and fine.

4. The viscosity of the material. That is, the greater the viscosity of the material, the easier it is to adhere. The material with high viscosity will adhere to the inner wall of the sand making chamber in the crusher. If it cannot be cleaned in time, it will seriously affect the working efficiency of the sand making machine, and it will seriously affect the normal operation of the sand making machine. Therefore, when selecting materials, it must be noted that the viscosity of the material should not be too large.

5. The humidity of the material, that is, the moisture contained in the material is large, the material is easy to adhere in the sand making machine, and it is easy to be blocked during the feeding process, resulting in a reduction in sand making capacity. To solve this problem, firstly, the material temperature should be strictly controlled when the material is selected. If the temperature of the selected material is too large, the sunshine or air drying method can be used to reduce the percentage of moisture in the material.

To produce the national standard sand, we must first select the material, how many mm is the feed size, and how much the required output is. All of the above can be flexibly selected according to the investment or actual site. Of course, the equipment is also determined according to this condition.
