The wheel sand washing machine is a kind of sand washing machine that uses the slow rotation of the wheel bucket to clean up the impurities covering the surface of the sand and gravel, and at the same time destroys the water vapor layer covering the sand and gravel material, which is convenient for the back. Dehydrated gravel material. The wheel sand washing machine is an indispensable equipment in the sand making production line. If the sand washing machine fails and the screen is blocked, it will affect the production efficiency of the entire production line. Jiangxi Hengchang Mining Machinery will give you a brief analysis of the four key factors that cause screen blockage.

1. The discharge port is blocked

If the discharge pipe of the sand washing machine is not smooth, the cyclone will be blocked; if the material is fed too fast, the air supply port of the equipment will be blocked; if it is not matched with the conveying equipment, the cyclone will be weakened or blocked after no wind. After the fault point is found, the air supply port is cleared first, the unmatched conveying equipment is replaced, and the feeding amount is adjusted to make the machine and equipment operate normally.

2. The conveyor belt is feeding too fast

If the conveyor belt feeds too fast, the feeding port of the sand washing machine will be blocked. Each sand washing machine has its own production standards. If the speed of the stone conveyed by the conveyor belt is too fast, the processing speed of the sand washing machine cannot keep up with the feeding speed, which may cause the feeding port of the sand washing machine to be blocked. In order to prevent the sand washing machine from being blocked, pay attention to the change of the pointer of the ammeter at any time during the feeding process of the sand washing machine. If the feeding amount is too large, the deflection angle of the ammeter pointer will be large. If the rated current is exceeded, it indicates that the motor is overloaded, and the long-term overloaded motor is easy to burn out. In this case, the operation of the sand washing machine should be stopped immediately, the excess stones accumulated should be removed, and then the conveying speed of the conveyor belt should be reduced to adjust the correct speed.

3. The moisture content of the material

The moisture content of the material will also affect the blockage of the feed port. Due to the high water content of the material, the material is easy to adhere to the feed port under the action of moisture. If it is not cleaned regularly, the feed port may be blocked. The blockage caused by this reason needs to control the water content of the sand and gravel, and clean the sand and gravel at the entrance in time.

4. Broken and aged sieve plate

Once the screen plate of the sand washing machine is broken and aged, the screen mesh is closed, and the water content of the crushed material is too high, which will cause the equipment to be blocked. To solve these problems, it is necessary to replace the broken and severely aged screen regularly, keep the equipment in good working condition, check that the power matches the sand output, and check the screen regularly, which can not only improve production efficiency, but also prevent sand washing The machine is blocked, thereby enhancing the usability of the equipment.
