What is the reason that the production capacity of sand making equipment does not meet expectations?

1. The humidity of the material. If the humidity of the material is too high, it will easily adhere to the inner wall of the equipment. If equipment is not cleaned in time, it will not only block the inlet and outlet, but also affect the working efficiency of the sand making machinery. If the humidity of the material is too high, we can reduce the moisture in the material by drying.

2. The hardness of the material. If the material is too hard, it will reduce the production capacity of the sand making equipment, and the equipment parts will accelerate wear. Therefore, it is necessary to select the appropriate sand making equipment according to the nature of the material.

3. Fineness of finished product. The higher the fineness requirements, the longer the sand making time, the lower the output. If the fineness requirements for the finished product are higher, you can consider adding a sand making equipment to improve production efficiency.

4. The quality of the equipment. The quality of the sand making equipment produced by different manufacturers is different, the quality is different, and the production capacity will also be different. When purchasing equipment, it is recommended to choose equipment from large manufacturers with competitive.

5. Maintenance of equipment. The maintenance of equipment is very important. Regular maintenance can not only increase the service life of the equipment, but also increase the output.

Usage of sand making machine

1. It is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete.

2. It is also used for sand making and shaping in the field of engineering such as water conservancy, hydro-electric power, high-class highway, railway, bridge and municipal works.

3. It is used in fine crushing of ming industry such as building materials, metallurgy, chemical engineer, ming, anti-fire material,cement etc.

4. Vertical shaft impact crusher is used for producing glass raw material and quartz sand etc.

Features and benefits

1. Simple and reasonable structure, lost running cost.

2. High crushing rate, energy-saving.

3. It has fine crush and coarse grinding function.

4. It is little affected by the moisture content, and the content can get up to about 8%.

5. It is suitable to crush medium hard, hard special materials.

6. Excellent product of cubic shape, and small fraction of elongated flaky particle shape.

7. Small wear from impeller liner, and easy maintenance.

8. Working noise is lower than 75 decibel, dust pollution.

Reasons for sudden shutdown of sand making machine

1. Material clogging in the crushing cavity

The blockage of the material will also cause the equipment to stop suddenly. At this time, the material must be cleaned up. In subsequent use, materials with large particle size or more water are prohibited from entering the machine, and the feeding should be kept uniform to avoid excessive feeding.

2. V-belt is too loose

Check if the v-belt is a problem. If it is too loose and causes downtime, adjust the tightness of the v-belt. If the v-belt loses its tightness due to prolonged use, replace the v-belt.

3. Unsuitable working voltage

When the working voltage of the production site is too low, it is not enough to maintain the normal operation of the sand making machine and shut down. In this case, select a voltage that meets the requirements of the device.

4. Internal parts fall off

If there is a metal collision sound before the equipment stops, it may be that a part in the crushing chamber falls and the sand making machine suddenly stops. At this time, the internal inspection of the equipment should be performed.

5. The impeller is stuck

When the inside of the crusher enters into hard objects such as metal, the impeller of the sand making machine may be stuck, causing the equipment to fail to work. Therefore, the hardness of the material must be strictly controlled to prevent the entry of unbreakable objects.

6. The bearing is locked or the spindle is broken

If it is caused by a broken spindle, repair or replace the worn spindle. If it is caused by the bearing lock, it is necessary to find out the cause of the lock, to properly install the bearing, ensure that the bearing has a certain working clearance, and do a good job of bearing lubrication, otherwise the problem cannot be solved fundamentally.

7. There is a problem with the device cable

If the connection line breaks or has poor contact, the sand making machine will also suddenly stop, especially when there is no sound without warning, it is likely that the connection line is out of order.

The above 7 reasons are the common situation that the sand making machine suddenly shuts down. If you encounter it again next time, it may be better to check from these aspects to avoid unnecessary cost waste.

With the growing demand for aggregates, the application of sand making machines has become more and more extensive. However, there will be inevitably encounter various problems when we operating sand making machine. The lighter will affect the production efficiency, and the heavy one will directly shorten the service life of equipment. So, during the operation of sand making machine, which action should be prohibited and which one must be done? If you want to know this, i believe you will understand after reading the following!

14 prohibitions items in use of sand making machine

1.no deironing 2.don't start up and shutdown when it has materials in machine 3.forbid to operate the machine with excessive current and low voltage 4.don't run when the machine has abnormal noise 5.don't check or adjust the machine when it is running 6.eccentric feeding of the machine is prohibited 7.forbid to crush large stones in crushing cavity (exceeding the maximum input size specified by the equipment) 8.lubricating oil shall not be lower than 15℃ when using sand making machine 9.forbid to run the crusher when lubricating oil temperature is higher than 60℃ 10.forbid to run the crusher when the lubricating oil filter is blocked 11.operation of the crusher is prohibited when the alarm light is on 12.don't run the crusher when the wheel is unbalanced 13.forbid to start another motor before starting one motor (for dual-electric sand making machine) 14.the crusher shall not be operated when the electrical cabinet of the lubrication station and the electrical cabinet of host are not interlocked.

9 things be a must when using sand making machine

1.feeding needs to be uniform. (per shift) 2.the lubrication filter must be checked for iron filings. (weekly) 3.it is necessary to check whether the oil level of lubricating oil is normal. (per shift) 4.the wearing parts must be checked for wear. (per shift) 5.the condition of all bolts and their fasteners must be checked. (per shift) 6.it must be checked whether the running current of two motors is the same. (per shift) 7.the tension of the v-belt must be checked. (per shift) 8.the contamination of lubricating oil must be checked. (weekly) 9.the thrower must be balanced when we use crusher after replacing the accessories. (after each replacement of accessories)
