Hard coal preparation in a single stage crushing circuit
The article concerned the problem of coal preparation for gasification purposes. The main aim was to design the coal crushing circuit, which would produce the material within the particle size range between 0.5 and 5 mm. The one-stage crushing circuit based on hammer crusher was proposed.It consists in dropping grains of coal and waste rock from the required height on a hard floor. Coal and waste rock grains, being more fragile, are crushed when dropping. The dense grains of the waste rock remain intact or broken to a small extent [21,22].

USGS Bulletin 1823 Preparation of Coal for Analysis
The coal sample, as received from the field, consists of 3 to 15 kg of material that first is reduced to a particle size of 2 to 4 mm (5 to 10 mesh) in a jaw crusher. This crushed material is then divided into three splits. The first split is forwarded to a laboratory for standard ultimate and proximate analyses.The crusher was running in a coal handling plant in steel plant. A simple schematic diagram of coal crusher with sensor orientation on bearing housing, a 3D crusher model and a photograph of Crusher NDE bearing with two sensors fixed in radial and horizontal direction are shown in Figs. 4, 5 and 6 respectively.

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.The coal feed rate, belt speed and crusher rotational speed are taken as the optimization variables; and, the energy cost, with consideration of time-of-use (TOU) tariff, is formulated as the objective function.
