COAL
Dr York Reichardt and Sven Heuer, Hazemag, Germany,
elaborate on the use of crushers in coal operations.
C
oal crushing applications differ in a wide variety of ways. Coarse
crushing of overburden and coal down to approximately 250 mm
directly at a capacity of up to 3000 tph in the mine with Hazemag
horizontal impact crushers enables downstream belt conveying
instead of trucks. Producing coal in a fineness range of -20 mm or -100 mm at a
capacity level of 100 – 3000 tph is a typical task for Hazemag feeder breakers,
sizers, roller crushers, impactors or hammer mills – depending on the coal
properties and the project data. For in the product range of 30 – 100 mm, scalping
before crushing proves to be very economic. For finer products such as -5 mm or
-0.3 mm, Hazemag hammer mills are very suitable.
