The dense medium cyclone for coal preparation is composed of a cylindrical cyclone and a cone combined cyclone in series. The cylindrical hydrocyclone is 10 °- thirty ° It is placed obliquely and connected in series with the cone hydrocyclone on the upper part. The separation is carried out from the low density. The low density coal is discharged from the overflow pipe at the lower part of the segmented cylindrical cyclone, and the intermediate product is discharged from the upper part. It enters the second segmented conical cyclone along the tangent direction, where the final middling coal and gangue are obtained. High quality clean coal and thin dense medium can be obtained from the section of dense medium cyclone, which can effectively improve the separation density of the second section.

All the heavy medium cyclone liners produced by our company are made of alo ceramic with a thickness of 20mm. Our company undertakes all kinds of cyclone maintenance business, such as repairing the iron shell and replacing the ceramic liner.

Structural features: 1. There are three discharge ports, which can separate qualified clean coal, medium coal and gangue with single low density suspension at one time; 2. High separation precision, wide range of selection strength, high upper limit of selection and wide range of application; 3. The selected material and suspension are separated into the cyclone to save power consumption, reduce the amount of gangue sliming and secondary slime, which is conducive to the reasonable layout of the process; 4. Simple structure, no moving parts, made of high aluminum ceramic and other materials in sections, good performance and long service life; 5. It is used for the classification of high sulfur, refractory and refractory raw coal.
