When you hear the words filter media, large companies or manufacturing plants come into mind. Generally, filtration is the process by which water and solid waste such as rocks are separated. A marble-making company is one of the places where filter press are utilized. The water is recycled after filtration and used later on at the marble cutting stage.

The structure of the strainer is not as complicated as one may think. The main machinery is the plates that are covered with filtration material. This filtration material tends to create a seal between the two plates. To avoid blockage inside the seal, the pump applies just enough pressure. The filtrated liquid goes through the filtration cloth and through the openings of the filtration media.

You may be wondering, how does the machine rid itself of the residue that has been separated from the filtrate. Letting it occupy space for a long time could lead to its blocking or breaking down. The first step is to stop the feeding pump from supplying the slurry. From there, the pressure holding the seal in place is released. Afterwards, the force of gravity is supposed to pull at the material until it drops.

It is common for people to think that the strainer media the plates in order to help the dewatering process. This is however not true. The feed pump distributor the adequate pressure to remove water from these solids. The two times that there is movement in the sifter is when it opens up to dispose of dried cakes and closes up again for a new cycle.

Unlike other technologies, there is simplicity in operating these filters. They have the capacity to select cycle times, cake wideness, a pressure of the feed pump and plate flair that allow achievement of the most dried cakes. This makes them practically automated and they would be the best in terms of managing time.

Maintenance is a key issue that contributes to a sifter either having a long life or breaking down every chance it gets. Every machinery needs to be serviced as often as needed otherwise, you may spend more money trying to fix it than you bought it. For overhead ray, there are no parts on the side of the media which makes it easier to change the sifter cloths.

The overhead beam is one of the types of sifter media available in the market. As the name suggests, the sifter plates hang from overhead ray. It so happens that there are no parts to the sides of the strainer, therefore, making it easier to maintain. For example, you do not have to remove the plates while changing the strainer cloths.

All in all, it is important that the press is taken care of as often as possible to avoid any irreversible damage. For example, the strainer cloth can be looked for rips at least once per cycle to avoid the unwanted material from passing through to the filtrated liquid.it should also be washed as often as needed and checked on cleanliness to avoid material settling between the cloth and the plates.
