1Ultra High Pressure Filter Press
Coal sludge is a by-product of the washing and processing of raw coal in coal preparation plant. For power coal beneficiation plant coal slurry generally refers to primary coal slurry, and coking coal beneficiation plant coal slurry generally refers to flotation tail coal slurry. Part of the coal slurry particle size composition of the coarse coal preparation plant can be used to pressurised filter recovery, a few coal preparation plant...

1.1 working principle of the filter press mainly consists of transmission part, filter plate part, pressure plate part, thrust plate part, pressure device (mainly hydraulic pressure device), hydraulic system, electronic control system and auxiliary parts. The filter cloth is installed on both sides of the filter plate, and under the action of the pressing device, the filter...
Experimental study and comparison of flocculants for solid-liquid separation in filter presses
(1) Pre-analysis of available flocculants The agents used for sludge conditioning can be divided into two categories: one is inorganic coagulants and the other is organic flocculants. Inorganic coagulants include iron and aluminium salts, two types of metal salts coagulants and polymerized alumina and other inorganic...
