Centrifugal Magnetic Filter


The difficulty to remove dusty, powdered particulates

Precision machining manufacturers work with grinding machines. Grinding process produces a large amount of grinding sludge that is usually composed of fine particulates in the size of microns and is hard to be filtered or extracted.

The most common method to clean the grinding sludge is thereby the replacement of the entire coolant tank. However, for workshops who use central coolant tank, it is exhausting for them to tackle replacement, and for factories who deal with high producing rate, it is neither industrial or economical to replace the coolant frequently.

By separating the grinding sludge with this Centrifugal Magnetic Filter, the iron powder and dust can be instantly extracted and discharged without the need of your manual cleaning and replacement.

Our product is to conform to ESG sustainable development goals, realize ESG's circular economy, be environmentally friendly, and reduce carbon tariffs.

Workflow of model FOODIE II
Front Coarse Filter
Capacity of 5.5L, the bucket intercepts large particulates like metal chips.
Vortex Dynamic Filter
The filtration removes up to 90% of 10μm particles in water-soluble cutting fluid and 80% in oil-base cutting fluid. The cyclone effect eliminates the need to replace filter core; i.e., no consumable material needed. No bubbles are formed as it does not blend in air.
Magnetic Separator
The roller is power-driven to improve draining. Magnetic metals, such as iron, are separated from massive quantity of powders or particles, making the design perfect for highly magnetic separation in large flow rate.
The device generates extreme magnetic field up to 5,000 Gausses, significantly efficient in removing tiny metal particles.
Sludge Cart (Optional)
The sludge separated by the magnetic separator will be discharged directly into the sludge cart. The cart is able to dry the sludge and collect the coolant residual for recycling and reuse.

Chips and sludge are sucked in through the inlet pipe


Big particulates will be remained in the front filter


Finer particulates pass into the vortex dynamic filter


Sludge gets filtered and delivered to the magnetic separator


Magnetic separator discharges the extracted sludge


Clean coolant returns to the tank


This centrifugal magnetic separator is fully assembled and installed before delivering to you. You can simply unpack it, connect the power and activate its operation.


Regularly maintain the magnetic separator by cleaning the sludge residuals being accumulated around the roller.

All our equipment is smartly structured with an openable front door for users to maintain conveniently at any time.
