Pressurised Two-Product DM Cyclones

Mining Cyclone Series

coal separation cyclonesPressurised two-product DM cyclones are high efficiency equipment for separation of raw coals in coal preparation industry. The are specially designed to minimise the vortex and abrasion and have features such as high top limit, excellent separation efficiency and great handling capacity.

Design of Feed Opening

The special structure of the feed opening with round front and square back section allows instant speed-up of the feed passing through it to meet the requirement on high feed rate.

Fixed ceramic tiles for the feed opening provide extremely good impact resistance.


cyclone feedingInvolute feeding is applied to the cyclones. A great deal of simulation and data analysis shows that involute feed can reduce turbulence generated by abrupt diffusion of the feed at the inlet to allow of smooth and stable flow inside the cyclones for better separation performance.

Small Cone and Underflow

Small cone and underflow, as very easy-to-wear positions, are lined with 18mm silicon carbide ceramics.
