Box crusher understandingDate: 2019-08-05 Views:
Box type crusher is also called the square box crusher, comprehensive ordinary heavy hammer crusher, counterattack crusher, vertical shaft hammer crusher and all kinds of use hammer hammer (board) for crushing the stone to hit on the mechanical principle of optimized design, the manufacture to produce a new generation crushing machinery products, changed to grate method to control the discharging grain big small, reduce wear hammer in the crushing cavity, to improve the service life of hammer head by 4 to 6 times, each pay a hammer head can be broken stone 340000 tons, realized the breakthrough of crushing technology, truly achieve the twice the result with half the effort.
1. Working principle of box crusher
Stone from the upper part of the machine directly into the high-speed rotation of the rotary table, under the action of high-speed centrifugal force, produce high speed impact and high density crushing, stone after hitting each other, and will form eddy current movement between the rotary table and the casing and cause many times of mutual impact, friction, crushing, until crushing into the required particle size.
2. Box crusher structure
The frame of the box crusher is a three-part structure. Just open the back shell of the crusher and you can change the board hammer, crushing board, lining board and other maintenance operations.Box crusher parts and components of the strong interchangeability, less vulnerable parts varieties, easy to spare parts procurement and management.Hydraulic opening device is used to open and close the shell, which can effectively reduce the maintenance labor intensity, improve the maintenance work efficiency and shorten the maintenance work time.The monitoring system of box crusher can monitor the operation of crusher at any time. The monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine.The drive system of box crusher adopts the mode of motor + mechanical coupling +V belt + crusher, which can effectively improve the starting performance of the motor and make it start and run smoothly.Belt transmission mode can play a double overload protection function, drive the motor power required by the system is low, greatly reduce the operating cost.The driving scheme is economical, practical, stable, safe and reliable.
