WEMCO - Flo-systems

The WEMCO® HYDROGRITTER® has three major components – a pump, a cyclone separator/concentrator, and a dewatering/washing classifier. The pump pulls grit from the grit chamber or other source and feeds it to the cyclone separator. The grit is then captured/concentrated and discharged into the spiral classifier, where it is washed and dewatered.

Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller classifiers have raking capacities as low as 1.5 t/h.
