The width of the crusher must also be considered when taking into account the feed size. Selecting a crusher that is too narrow compared to the size of the incoming feed can result in the bridging of the feed material across the crusher opening. When this occurs, once again, throughput capacity is diminished and plugging of the chutes can occur.

Properties of coal gangue feed, especially its particle size distribution (PSD) and variable hardness, result in considerable impacts on both the efficiencies of the circulating fluidized bed (CFB) boiler and wastage of crushers. These two aspects are addressed in this study. First, the Aspen Plus software was used to optimize the coal gangue crushing system for the CFB boiler; it facilitated ...

Mining of raw materials is a process that consists of several stages. In openpit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture content, capacity of crusher, abrasiveness ...

The crushing rolls can be rotated either inward or outward at slow speed and high torque, which minimizes slippage and fines generation. Slowspeed Sizers are selected for the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency.

It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is: R = 100/E/r1 where R = circulating load, % E = screen efficiency, % r = % oversize in crusher product. To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher.

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
