Horizontal filter press

Working principle:
The filter press introduces pulp under high pressure into the cavities (chambers) formed between adjacent vertical plates. 

During the filtration cycle, the plates are pressed firmly against each other by means of special hydraulic pushers, sealing them against the internal pressure acting on the pulp side.

The pressure from the pulp side is applied until the filtrate, after passing through the filter cloths, exits in such a quantity that the required degree of dewatering is achieved.

Optional: 

• Compression of the resulting sludge with a diaphragm to reduce residual moisture.
  
• Washing of the sludge received.
• Blowing through the sludge to reduce residual moisture. 
• The plates are then pulled apart to release the dewatered slurry, called "cake".

The process is batch-based and consists of the following steps:

• Closing the filter press chambers.
  
• Filling of the chambers with sludge;
• Optional: Sludge squeezing by diaphragm / sludge washing / sludge blowing with air;
• Opening of the plate pack and unloading of the dewatered sludge (cake);
• Filter screen regeneration
  

1. Simple construction and reliable operation
   
2. The basic delivery includes shaking and rinsing units.
   

Efficiency:

The duration of the main operations on horizontal filter presses depends on the properties of the filtered sludge and the filtering mode.

The residual moisture and purity of the filtrate depends on the correct selection of the filter screen and the filtering conditions

Objects of application:

• Non-ferrous metallurgy: dewatering of non-ferrous ore concentrate slurries; fine treatment of electrolyte solutions; dewatering of metallurgical effluents;
