Absence made counterattack crusher productivity factors

Counterattack crusher productivity is an important performance indexes of crusher There are many factors that affect the productivity: the mechanical and physical properties of rocks and structural parameters of the crusher two aspects

The influence of the physical and mechanical properties of the rock:

This is determined by the stone source and the needs of the project

1 The strength of the rock
In the process of crushing, mainly on the compressive strength of the rock as crushing index of ease Because platts hardness and compressive strength has a certain relationship, and more intuitive to reflect the crushing operation, to the difficulty of the project, often with platts hardness coefficient of rock classification Rock platts hardness coefficient is larger, the compressive strength is larger, the more difficult to break, breaker productivity is low Conversely, the smaller the platts hardness coefficient, crusher productivity is high
2 The humidity of material
Rocks containing certain moisture to have no effect on rock broken, but when the rock containing a certain amount of mud or broken after the powder particles, fine grained or mud will cluster, sometimes will be binding on the coarse particle or crushing cavity walls Reducing the discharging speed, reduce the productivity Serious when discharging mouth blockage, further influence the production

Counterattack crusher structure parameters influence:

Different structural parameters of the counterattack crusher is different, choose suitable structure parameters of the crusher, in order to satisfy different rock material crushing homework, is crucial for the design and selection of broken machinery

1 The counterattack crusher clamp Angle
The tong Angle is too large, the broken cavity can not clip rock, rock easily beat up and can not be broken, and even safety accidents Clamp Angle after hours, the broken ratio is too small and cannot satisfy the requirement of the stone crushing process Therefore, should have a suitable clamp Angle
2 Counterattack crusher discharging mouth size
Discharging mouth will affect the size of the corner of the forceps counterattack crusher and broken ratio On the premise of meet the use requirement, increase the discharging mouth size, can reduce the clamp Angle and broken ratio, improve productivity On the contrary, to decrease the size of discharging mouth, productivity would be reduced A lot of broken cold machine discharging mouth size are equipped with adjusting device, so as to adapt to different application requirements
