Different Types of Filter Plates

There are different types of filter plates for filter presses, and their uses vary. Different types of filter plates are used for different occasions. The following will introduce various materials and types of filter plates.

Filter Plate Shape and Size

The size and shape of filter plates also vary, as some special industries require the use of special filter plates, such as round high-pressure filter plates for processing ceramics and kaolin.

Round filter plates
The round filter plate is a special shape that can withstand high pressure and is suitable for industries such as ceramics, kaolin, and stone.

Filter Plate Material

The choice of filter plate materials depends on the medium and working conditions of the processing. Common materials include polypropylene (PP), polyethylene (PE), cast iron, stainless steel, etc. If high-temperature and high-pressure filter boards are needed, a special formula custom filter board can be added.

Cast Iron Filter Plate
It can be made from cast iron materials and can withstand higher temperatures and corrosion. It is suitable for handling some materials with high corrosive or higher temperatures.

Stainless Steel Filter Plate
It is made of 304/316 stainless steel. It can be used for food-grade materials according to demand and is suitable for the food, beverage, and pharmaceutical industries.

Filter Plate Structure

According to application requirements, the structure design of the filter board can be different, including plate and frame filter plate, recessed filter plate, diaphragm filter plate, and gasketed filter plate.

Plate and Frame Filter Plate
It consists of a filter frame and a solid filter plate. Its feeding position is different from that of ordinary chamber filter plates; that is, it feeds from the corner hole.

Recessed Filter Plate
Each filter plate has a depression, and every two filter plates form a filter chamber. It is one of the most commonly used filter plates.

Membrane Filter Plate
There is an elastic membrane on the outside of the filter plate to squeeze the filter cake for the second time and improve the dryness of the filter cake.

Gasketed Filter Plate
There are recessed grooves on both sides of the filter plate for embedding the filter cloth. The filter plate is highly airtight and is suitable for some industries that require no leakage.
