Sand making machine plays an irreplaceable role in the sand making of various ores, and it is the most effective and reliable sand making equipment at present. But the broken materials are hard materials such as limestone, marble and granite. In production, the sand maker will inevitably encounter various problems. Once the machine breaks down, it will affect the production efficiency and economic benefits. The following small series will introduce you to several common fault handling methods.

1. What if the equipment is unstable?

Reason for failure:

① The wearing parts on the impeller are seriously worn;

② The feeding particle size is too large;

(3) Impeller channel is blocked, which causes uneven feeding and swinging.

Solution:

(1) Check the worn parts and replace them in time to balance the impeller;

(2) Strictly control the particle size of the feed, which cannot exceed the maximum allowed by the equipment;

(3) Check the blockage on the impeller wheel and take it out, and often clean the crushing cavity.

2. The equipment makes abnormal noise during operation.

Reason for failure:

The connecting bolts or wearing parts such as liner and impeller inside the sand making machine are loose.

Solution:

Stop the machine immediately for cleaning, and re-fasten and install loose parts.

3, bearing operation is not flexible

Reason for failure:

Materials enter the sealing cover of bearing of sand making machine, etc.

Solution:

Open the sealing cover to remove foreign matter.

4, bearing temperature rise

Reason for failure:

(1) There is dust on the bearing. ;

② The bearing is badly worn;

③ Bearings need lubricating oil.

Solution:

(1) Clean up the dust in time;

② Replace the bearing with a new one;

③ Add lubricating oil in time.

5. The discharging granularity becomes larger.

Reason for failure:

① Long-term operation of the equipment leads to loose V-belt of the transmission part;

② feed particle size is too large;

(3) The impeller speed is unreasonable and the efficiency becomes low.

Solution:

① Adjust the tightness of the V-belt or replace it;

(2) Strictly control the feed granularity and feed according to the standard;

③ Adjust the impeller speed to reach a reasonable standard.
