hammer crusher principle

How to calculate the parameters of the basic structure of hammer crusher ?

After emergence from hammer crusher , crushing its better than the safe and reliable operation , low energy consumption , in mining, coal, chemical , electric power, building materials and other industries widely used. Performance crusher their basic structure is reasonable parameter selection has a very close relationship , this paper describes the calculation method to hammer crusher basic structural parameters .

The diameter and length of the rotor :

Average diameter of the rotor is determined according to the size of the ore . Typically the diameter of the rotor compared to the size of the ore block 4-8 , the approximated large crusher 2 . For medium-sized hammer crusher , ore than the diameter to the size of the take 7 , and processing the material particle size not greater than 120mm. According to the relationship between the diameter of the rotor is known particle size and the ratio of the size of the processing of the product .

Production capacity of the crusher according to the length of the rotor is determined to be . And the ratio of the length of the rotor diameter is generally 0.7 to 1.5 , ores strong impact resistance , you should select a larger ratio . The length of the rotor to take the rotor diameter , the ratio between the rotor diameter and length of the product.

The basic structure size to determine: the width and length of the mine to the port . Hammer crusher to the mine mouth width B 3dmax, dmax is the maximum size of the ore block . Pai mine mouth size . Hammer crusher discharge port has a grate mine clearance size control , generally into the ground to determine the size requirements . . When crushing brittle material , in order to improve productivity, the gap size of the screen can be increased .

Way to mine the ore guides elevation , hammer crusher ore blocks required to have a certain vertical falling speed , so I set mine to the top of the rack .
