ENTA - Recprotating Rake Classifier

The rake classfier can be sited adjacent to the point of grit collection. The classifier is designed to receive a grit and water mixture by gravity from a flat bed grit collector. The unit can also be standalone in either a concrete or steel fabricated chamber. This can be fed by a pump rising main. The pump can be of the centrifugal type, positive displacement or air lift. When this option is preferred a receiving header box is positioned on top of the unit to ensure the correct pattern of feed is achieved.

In a declined trough, the coarse material is scraped upwards by a rake. At the return point, the rake is lifted, moved back down to the initial position and lowered onto the bottom of the trough. The fine material remains suspended and flows out over a weir at the lower end of the trough. The slurry-feed intake is located about a third of the way up from the lower end of the trough.

Our rake classifier is used for grit removal in various processes. It is made of mild steel and has a complex motion transmission mechanism which is highly effective.

Our range of grit removal equipment consists of Cross Flow Detritors up to 12.0m dia, traveling grit dredgers and combined grit and grease removal. In addition to grit removal products there is a choice of grit classification units of the reciprocating rake type and the screw classifier type.
