Trommels for Dewatering

Trommels are used in a wide range of screening and separating the mining and minerals sectors.  They can also be seen in abbattoirs, quarrying, recycling, topsoil preparation and in fact anywhere where large quantities of materials need separating or grading.

They are of simple design but highly effective in operation—consisting of a perforated revolving drum inside an outer casing.   The water and slurry mixture is pumped into the revolving drum whose action retains the solids in the slurry and allows the water to drain into a sump for recovery or disposal.  Solids are moved out of the drum by the action of a raised thread fitted to the drum’s inner surface.

Chess can design and build trommels to clients’ exact requirements.  They can be mobile—either fitted to trucks or with their own undercarriage;  have interchangeable screens of different sizes and be fitted with power sources and control systems to suit the application.
