The potential safety hazards in the operation of river pebble sand making machines mainly come from the equipment itself, the operation process and environmental factors. Old equipment and improper maintenance can easily lead to mechanical failure; improper operation, such as failure to wear protective equipment and illegal operation, will increase the risk of accidents. The following mainly introduces several safety hazards of river pebble sand and stone sand making machines:

1. Unstable operation and excessive swing of the machine body

There are three main reasons for this phenomenon: 1) The wearing parts on the impeller of the river pebble sand making machine are seriously worn; 2) It is caused by the large feed particle size; 3) There are obstructions in the impeller flow, which makes the feed uneven and causes the swing phenomenon;

The solutions to this phenomenon are mainly as follows: 1) Replace the wearing parts to balance the impeller inside the river pebble sand making machine; 2) Strictly control the feed particle size; 3) Remove the obstructions on the impeller flow, and clean the crushing chamber frequently to prevent blockage;

2. Abnormal noise during the working process

The abnormal noise of the river pebble sand making machine is often caused by the loosening and falling off of internal connecting bolts, linings, impellers and other components. The solution is to stop the machine immediately, check and tighten or replace loose parts to ensure stable operation of the equipment and restore sand making efficiency and safety.

3. Inflexible bearing operation

Foreign matter in the bearing sealing cover causes poor operation and affects the operation of the river pebble sand making machine. The solution is to open the sealing cover, thoroughly remove foreign matter, ensure flexible rotation of the bearing, thereby restoring the smooth operation of the equipment and ensuring the normal operation efficiency of the river pebble sand making machine.

4. Bearing temperature rises

There are three main reasons for this phenomenon: 1) dust and other foreign matter enters the bearing parts of the river pebble sand making machine; 2) the bearing is worn and damaged; 3) the bearing is short of oil;

The solutions are as follows: 1) clean the foreign matter entering the bearing parts; 2) replace the damaged bearings in the river pebble sand making machine; 3) add lubricating oil to the bearings regularly and quantitatively to prevent the phenomenon of oil shortage;

5. The particle size of the discharge increases

In the production of the river pebble sand making machine, the size of the discharge particle size needs to strictly meet the production requirements. The phenomenon of large discharge particle size is mainly caused by the following three reasons: 1) the V-belt of the transmission part is loosened due to long-term operation of the equipment; 2) the feed particle size is too large; 3) the impeller speed is unreasonable and the efficiency is low;

The solutions to this phenomenon are mainly as follows: 1) adjust the belt tightness; 2) feed strictly according to the requirements of the river pebble sand making machine to prevent the feed particle size from exceeding the range required by the equipment; 3) adjust the impeller speed to meet the production requirements.
