Optimal operation of coal conveying systems assembled with crushers

The MPC strategy for our coal conveying system is configured as follows. Its operating process is illustrated in Fig. 2, where the control horizon is set to N = 72 as well for the purpose of comparison study. In Fig. 2, m is sample time. Suppose MPC start at m = 0, an open loop optimal operation problem over the control horizon [0,72) is solved to get Operating the crusher with a completely filled crushing chamber.

Coal comminution and sizing ScienceDirect

Schematic of roll crushers for coal breakage: (a) single-roll crusher; (b) double-roll crusher. Single-roll crushers may be either feeder-breakers, or conventional rolls. The rolls on feeder-breakers resemble the cutting head of continuous coal mining machines. Example calculation. A coal is to be screened at 0.5 inchesduring the process of its crushing coal. The record shows random oscillatory motion typical of a situation in which the eccentricity of a rotating shaft keeps chang ing. This is expected in a crusher as the centre of gravity of the coal mass changes arbitrarily within crusher chamber.Dynamic Characteristics of Crusher Supporting Structures
