Application of ``water only`` cyclone in Slovak steam coal

Dec 31, 1998The paper deals with the possibilities of water only cyclone application in steam coal preparation with the aim to decrease the ash content in coal and to increase the coal heating value. The steam coal of the three Slovak coal localities from the Upper Nitra Basin was subjected to separation in a hydrocyclone without using a heavy medium.

principles of hydrocyclone separators

Principle of operation. Centrifugal forces are the effective principles of the separation processes in the hydrocyclones. The suspended particles are thrown radially to the outside. Because of the magnified field of force, high settling rates, fast separation and high load are obtained. Flow promoting designs ensure high accuracy of separation.
