CDE Asia recently installed and commissioned a project in India to recover china clay which was bound around silica sand rock.

The Problem

The customer was manually washing the material for clay recovery. The product thus obtained was not meeting the market demand as the grains were quite large and the recovered clay had a significant presence of mica.

The Solution

MicroGrader® - CDE’s patented wet processing system subjected the clay bound silica rocks to intensive scrubbing using ShearClean Attrition Cell technology and washed them over a series of fine classification systems to screen at extremely fine apertures. The combination of attrition and screening process separated the clay and mica from the silica rock granules. The combined clay slurry then passed through CDE Nanowash hydrocyclone classification system, accurately set for fine separation, to recover the product in a fine-grained form. The fully automatic IoT enabled processing system included subjecting the recovered clay to the hydrocyclone’s overflow, thickening it for water recovery, and further dewatering it to arrive at the finished form ready for market. The clay now met the customer’s requirement of particle size, fineness and is devoid of mica.
