Operators can then calculate the number of days per week the machine will be in operation to determine tonnage outputs. For example, if a company …
The crushing ratio of a jaw crusher is determined by the size of its feed opening and the width of its crushing chamber. The ratio can be calculated using the following formula: Crushing ratio ...
The life of wear parts increases. A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher. Feeding fines into the crusher may increase peak stress loads because of packing ? ie material being compacted as far as it compacts. This is enhanced by moisture, which again is highest in the fines …
Will's Textbook (8th ed) gives a better equation (here on the right): Q = W*S*s*cot (a)*k*N*60. The Q is vol throughput, m³/h. W is inner width of crusher, m. S is open side setting, m. s is jaw throw, m. a is the nip angle. k is a material factor, 1.5 to 2.0 (includes your epsilon param) N is …
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth. When the movable jaw goes towards the fixed jaw, it squishes the stuff in between and breaks it into smaller bits. ...
