KEK Cone Mills

KEK Cone Mills


The KEK Cone Mill is recognised as one of the most versatile size reduction machines in the powder processing industry. It has the ability to take a wide range of feed material and produce an equally wide range of product, The KEK Cone Mill is ideal for intermediate sizing in both wet and dry granulation processes.

It provides a gentle low energy form of size reduction and eliminates traditional milling problems including noise, dust, and heat. The gentle grinding action is capable of control within fine limits while maintaining a close particle size distribution with minimal fines generation, typical milled particle size range D50 – 500μ to < 250μ.

The KEK Cone Mill is a low energy size reduction machine for fatty, heat sensitive, sticky, moist or otherwise difficult to grind products.
