Construction Waste Crusher
is mainly used in two ways to realize overload risk and the adjustment of discharge port:
A: is the use of hydraulic hydraulic gyratory crusher, which is situated on the main shaft piston in the hydraulic cylinder, hydraulic piston change under oil volume cone crusher can change the position, thus changing the size of the discharging port. When overloaded, the spindle downward pressure, forcing the plunger into the hydraulic oil in the hydraulic transmission system of accumulator, broken cone ensuing decline in the increase of the discharge, discharge into the crushing chamber with non - crushed material material (iron, wood etc.) in order to achieve insurance.
Two: is the use of mechanical means to adjust the upper end of its spindle nut, rotate the adjustment nut, cone crusher can decrease or increase the discharge becomes larger or smaller, overload, cut off the pin on the drive pulley to achieve insurance.
The upper and lower movement of jaw jaw crusher can promote the discharging, and the horizontal stroke of the upper part is larger than the lower part, and it is easy to crush large pieces of materials, so the crushing efficiency is higher than the double elbow plate. Its disadvantage is that the jaw plate wears faster, and the material will smash and increase the energy consumption. In order to protect the important parts of the machine, not because of overload.
When the jaw crusher is overloaded, the conical shell forces the spring to compress itself so as to increase the discharge port and discharge the non crushing material. The adjustment of the discharging port is carried out by adjusting sleeve, and the adjusting sleeve of the shell is rotated to drive the shell to rise or fall by the thread on the outer circle, so as to change the size of the discharge port. The safety and adjustment of the hydraulic gyratory crusher are the same as that of the hydraulic cone crusher.
