What are the common problems during the use of a slag remover?

As a key device for separating impurities in industries such as papermaking and chemical engineering, the operation status of the slag remover directly affects product quality and production efficiency. However, in actual use, the slag remover often experiences a decline in separation effect and frequent equipment failures due to improper operation, insufficient maintenance or design flaws. The following are common problems and corresponding strategies in the use of slag removers.

1. The separation efficiency has declined

Reduced separation efficiency is one of the common faults of slag removers, mainly manifested as incomplete removal of impurities and the retention of fine particles in the good slurry. This is usually caused by fluctuations in feed concentration, unstable pressure or equipment wear. For instance, an excessively high feed concentration can lead to an increase in fluid viscosity, making it difficult for impurities to settle. Insufficient pressure, however, will slow down the slurry flow rate and shorten the separation time. In addition, wear on the inner wall or conical part of the slag remover will disrupt the stability of the flow field and reduce the separation accuracy. Countermeasures: Regularly calibrate the feed concentration and pressure parameters to ensure they are within the design range of the equipment; Regularly inspect and replace worn parts, such as ceramic linings or metal cones.

Ii. Clogging and Scaling

The interior of the slag remover is prone to clogging due to the accumulation of impurities or chemical precipitation, especially when dealing with high-viscosity or gel-containing materials. Blockage not only reduces the processing capacity but may also cause equipment overheating or motor overload. Countermeasures: Install a pre-screening device to filter out large particle impurities; Regularly rinse the interior of the slag remover with high-pressure water or chemical cleaning agents. For materials prone to scaling, the pH value can be adjusted or a dispersant can be added to reduce sedimentation.

Iii. Abnormal increase in energy consumption

A sudden increase in energy consumption during the operation of a slag remover is often related to internal mechanical failures or flow field disorders. For instance, bearing wear can lead to an increase in rotational resistance and a rise in motor load. Uneven distribution of the feed may cause vortices and increase energy loss. Countermeasures: Establish an equipment inspection system and regularly check the wear conditions of components such as bearings and seals. Optimize the design of the feeding pipeline to ensure the uniform distribution of the slurry.

Four. Excessive noise and vibration

Abnormal noise or vibration often indicates that the equipment is unbalanced or loose, such as rotor dynamic balance failure, loose foundation bolts, etc. Long-term neglect may lead to equipment damage or safety accidents. Countermeasures: Immediately stop the machine for inspection and recalibrate the rotor dynamic balance. Tighten all connecting parts and conduct comprehensive maintenance of the equipment on a regular basis.
