coal crusher. Ring hammer crusher is suitable for crushing various fragile materials which are moderately hard and have weak corrosives, such as in mining, cement, coal, metallurgy, building materials, roads, and burning departments. The grates' gap of Ring hammer crusher can be adjusted to meet clients' need.
"If the coal size is too large (>25mm in the specific case of Lak Vijaya plant), a separate crusher is invoked to crush and reduce size before being sent to the pulveriser," the members observe. "This needs additional energy and wear and tear of the crusher. For coal which is too small (<2mm), it behaves like dust.

Influencing Factors: Grain size distribution 1. normal raw coal has 30% ~ 50% of grain size < 3 mm. the caking ability of coal decreases when the fraction below 0.2 mm is increased. Separate grain size of4 ~ 6mm by screening before crushing to reduce the fraction below 0.2 mm. Typical coal size distribution. Simon Steinbach
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
9.3 Coal Crushing. It has been stressed that the coal supplier should initially crush the materials to a maximum size such as 300 mm, but they may be something else depending on the agreement or coal tie up. To circumvent the situation, the CHP keeps a crushing provision so that coal bunkers receive the materials at a maximum size of about 20 ...

The output size of coal affects the performance of CHP. Naturally these two hard surfaces are critical parts. One of these surfaces are known as grinding plates and other may known as rings, hammers etc. The linkage between crusher rotor and drive assembly are also critical parts. As failure of these linkages will stop crushing. 3.2 Wagon ...
