MONSOON - Finest in Classifying



This type of classifier does not require any peripheral equipment such as fans, filters etc. Feed enters the MONSOON classifier at a controlled rate from the top and falls onto a rotating distributor plate.

The plate disperses the product into an adjustable airstream which is generated by the internal fan. The fines are entrained in the air stream and are carried over to the outer cone whilst the coarse particles fall down into the inner cone. The products are discharged from the bottom of the machine. This self contained process significantly reduces investment, maintenance and operating costs. The MONSOON classifier has been developed especially for the separation of fine products between 45-300μm. High yields are achieved at very low specific energy consumption.


To improve screening efficiency the MONSOON classifier can be operated prior to a screening machine. This MONSOON is used to "de-dust" the incoming material at typically 75-125μm. This installation will not only improve the screening efficiency, but also produce a second „fine” product. For abrasive products all rotating parts as well as all parts in contact with the product can be lined with Ceramic or Polyurethane. Furthermore hardened material can be use for all wear affected parts as well.


When the material to be processed is abrasive, the inlet chute and the rotating parts are either hardened or lined as appropriate. In addition, the body itself can be lined with ceramic tiles or polyurethane if iron

contamination is to be avoided.
