INTRODUCTION
The Graymills combined Coolant Tank, Bed Filter and
(optional) Magnetic Separator are designed to keep your
cutting, grinding, drilling and milling machinery operating
at peak performance. By filtering out harmful contaminants,
coolant life is greatly extended, saving both replacement and
labor costs.
Coolant flows into the diffuser tray, which separates larger
chips and milling by-products. The liquid then pours onto
the filter bed where it is sieved by the filter media. As the
contaminants accumulate and clog the filter media, the solution
rises in the filter bed until the float switch is triggered. This
starts the motor that moves the chain conveyor/filter media
along, until it is replaced by clean material. The soiled filter
media is moved to a sludge box.
The benefits are:
• Keeps the coolant clean. Reduces frequency of coolant
replacement. Reduces operating costs.
• Keeps the workpiece surface cleaner.
• Grinding wheel does not need to be dressed as often.
Increases productivity and grinding wheel life.
