Rotary drum filter

Karnataka-based Universal Precision Tools manufactures rotary drum filter, a new design concept in coolant filtration. These are specially designed to handle floating and stubborn chips such as aluminium, brass and CI, which pose serious problems in filtering. These filters are simple and compact in design and eliminate dirty tank and filter pump. The filter can be directly connected to the machine outlet through a chute from which the chips with coolant are discharged. A scraper conveying mechanism continuously carries the heavy chips. The coolant flows through a rotary drum, which has a fine stainless steel mesh around. After filtration, coolant is collected in the integral clean coolant tank. The fine and floating particles get deposited on the drum. The continuous coolant jet diverted from the supply pump itself cleans the drum, and the deposited chips are carried away by the scraper in the form of sludge. The system works on "upward flow" principle where the difference in level of coolant is used for siphon action. These are available in flow rates of 100 lpm to 1000 lpm.
