crusher. Since most mechanical sampling systems include some degree of preparation of the coal sample, the downstream processing of the sample material within the system is an extremely important function. Although it is necessary for all parts of the mechanical sampling system to . operate properly and in sync, the crusher is one of the more ...
d1 and d2 are parameters that are characteristic of the crusher. They are determined primarily by the setting of the crusher. Data from operating crusher machines indicate that both d1 and d2 are proportional to the closed side setting. d1 is the smallest size particle that can be retained in the crushing zone during the opening phase of the cycle.
