cone crusher Installation of hollow eccentric shaft
A. Before installation, put the mat on the bottom cover. Then, use a sling to put the cover under the frame. After that, put the upper round plate and lower round plate on the bottom cover in sequence and make sure the heave place on the lower plate and the concave place in the bottom cover is locked. (diagram 4)
B. When installing the hollow eccentric shaft, a round-end bolt can be used to put the eccentric shaft into the central hole in the frame. Be sure the gears are not stricken when installing. (diagram 5)
C. After installation, the out surface of the big and small gear must be at same level and check the gap between the gears. the warp is about 3-3.7mm, and the tooth top gap is 6.2mm. (diagram 6)
cone crusher Structure and working principle
The crusher consists of mainframe, transmission device, hollow eccentric shaft, crushing cone, adjustment device, adjustment cover, springs and hydraulic station for adjusting
the discharge opening.
During the operation, the motor drive the eccentric cover to rotate through the horizontal axle and bevel gears. The center axle of crushing cone swings with the force of the
eccentric shaft cover so that the crushing surface is close to the mortar from time to time. In this way, the materials will be crushed through continuous pressing.
I. the Maintenance of cone crusher
1).maintaince Notes of cone crusher
A. The materials must be in the middle of the distributor. It is not allowed to put the materials into the crushing chamber directly, because it will make the crusher overloaded and the liner plate will be abraded unevenly.
Correct feeding conditions:
a. The materials are distributed equally to the crushing chamber.
b. The quantity of materials should not higher than the mortar.
B. The max feeding size should not equal to the feed opening, (the max feeding size≤85% of the feed opening) otherwise, it will lead to:
a. The capacity is low
b. Some spare parts will be damaged.
C. the cone Crusher is not allowed to start in overload condition in case of accident.
D. When stop the crusher, stop the feeder first. After the materials are all discharged out, stop the crusher.
E. The locking system and hydraulic station should be checked often to avoid problems.
2). Capacity of the cone crusher
Capacity is subject to feeding method, material size, size of final product, material nature, temperature, etc. the range is wide. The capacity is under certain conditions.
3). Change of mortar for cone crusher
There are u-shaped bolts on the adjusting ring. Fill zinc alloy into the space. When installing or changing the mortar, after 6-8 hours’ operation, check the fastening conditions and screw the U-shaped bolts again.
4). Change of thecone crusher inner wall
The cone crusher inner wall is fixed to the cone crusher body through a cone end. There is zinc alloy between them. When installing or changing the inner wall, after 6-8 hours’ operation, check the fastening conditions. If there is loose, fasten it.
