How does the jaw crusher adjust the size of the discharge opening?

The jaw crusher mainly uses two methods to realize the possible risk of overload and the adjustment of the discharge port:

Method 1: It is a hydraulic rotary crusher with hydraulic mode. The main shaft is located on the plunger in the hydraulic cylinder. By changing the volume of hydraulic oil under the plunger, the upper and lower positions of the crushing cone can be changed, thereby changing the size of the discharge opening.

When overloaded, the downward pressure of the main shaft increases, forcing the hydraulic oil under the plunger to enter the accumulator in the hydraulic transmission system, causing the crushing cone to descend to increase the discharge opening and discharge the non-material entering the crushing chamber. Broken matter (iron, wood, etc.) to achieve insurance.

Method 2: It adopts the mechanical method. The upper end of the main shaft has an adjusting nut and the rotating adjusting nut. The crushing cone can be lowered or raised, so that the discharge opening becomes larger or smaller. When overloading, the insurance on the cutting drive pulley is cut off. Sold to achieve insurance.

The up and down movement of the jaw crushing motorized raft has the function of promoting discharge, and the horizontal stroke of the upper part is larger than the lower part, which is easy to crush large pieces of material, so the crushing efficiency is higher than that of the double bracket type. Its disadvantage is that the jaws wear faster and the material is over-crushed to increase energy consumption. In order to protect important parts of the machine from overload.

When the jaw crusher is overloaded, the conical shell forces the spring to compress and raise itself to increase the discharge opening and discharge the non-crushed material. The adjustment of the discharge opening is performed by adjusting the sleeve, and the adjustment sleeve of the housing is rotated to drive the housing to rise or fall by the thread on the outer circumference to change the size of the discharge opening. The hydraulic gyratory crusher is secured and adjusted in the same way as the hydraulic cone crusher.
