Aiming at the problems of slow coal slime feed and high water content of mud cake, it can be solved from the following aspects:

First, solve the problem of slow feed of slime

Check pump body and pump frame:

Confirm whether the pump body and pump frame structure of the slime pump are reasonable, and whether the wear resistance and corrosion resistance are good.

If the pump body and pump frame are damaged or worn excessively, the relevant parts need to be replaced in time to ensure the flow rate and efficiency of the pump.

Clean the inlet end:

Check regularly whether the inlet part of the slime pump has flow path accumulation, foreign matter and so on.

Clean up inlet lumps to ensure smooth inlet pipes to improve pump water efficiency.

Check exit:

Confirm that the outlet of the slime pump is smooth and the valve is open normally.

Repair or replace uneven or damaged water outlets and valves to restore pump water speed.

Regular care and maintenance:

Develop a regular maintenance and maintenance plan for the slime pump, including inspection, cleaning and repair.

Ensure that the slime pump is in good working condition to improve its operating efficiency and stability.

Two, to solve the problem of high moisture content of mud cake

Increase feed concentration:

When the feed concentration of slime is low, the moisture content in the mud cake will be relatively high.

By increasing the feed concentration, the moisture content of the mud cake can be effectively reduced.

Increase press pressure:

Pressing pressure is one of the key factors affecting the moisture content of mud cake.

Increasing the pressing pressure appropriately can make the moisture in the mud cake more fully extruded, thereby reducing the moisture content.

Extended press time:

Insufficient pressing time will also cause the water in the mud cake to not be fully squeezed out.

Reasonably arrange the pressing time to ensure that the mud cake has enough time to dehydrate.

Cleaning and replacing filter cloth:

The permeability and filtration performance of the filter cloth directly affect the drying degree of the mud cake.

Regularly clean and replace clogged or damaged filter cloth to ensure its normal operation and filtration effect.

Optimization Follow-up procedure:

Check whether problems exist in subsequent procedures, such as soaking and drying.

Optimize the parameters and operations of these steps to ensure that the mud cake moisture content is effectively controlled.

In summary, by comprehensively considering all aspects of the slime pump and filter press, and taking corresponding measures to improve and optimize, the problems of slow coal slime feed and high water content of mud cake can be effectively solved.
