About Paper Band Filter

What is a Paper Band Filter?

A Paper Band Filter is a gravity-based filtration system used to remove metal chips, sludge, and contaminants from industrial coolants, oils, and lubricants.

It uses a disposable filter paper laid over a conveyor mesh. The fluid flows through the paper, and contaminants are retained. It is widely used in grinding and machining operations.

COMPONENTS (WITH FUNCTION)

WORKING PRINCIPLE (STEP-BY-STEP)

1. Dirty coolant enters the system.
2. It flows over the filter paper laid on a wire mesh.
3. Solid particles are trapped on the paper surface.
4. Clean coolant passes through into the clean tank.
5. As clogging increases, liquid level rises.
6. Float switch activates the motor to move paper forward.
7. Fresh paper comes in, dirty paper is discarded into a bin.
8. Clean coolant is pumped back to the machine.
