1. In the process of crushing, the moving cone liner and the fixed cone liner are constantly worn, which makes the ore outlet graally increase. In order to ensure a certain proct size, it is necessary to adjust the size of the ore outlet with the wear condition. The adjustment of ore outlet is realized by means of serrated thread rising and falling cone liner between adjusting ring and supporting sleeve
in order to make the tooth thread lubricated and easy to adjust and disassemble, the thread must have enough clearance
for the adjusted ore outlet, the steel wire shot put method can be used to measure the size of the ore outlet from the crushing chamber to the ore outlet. It is enough to measure one point for the processed new liner, and 6-8 points for the unprocessed or worn liner. After the discharge port meets the size requirements, the adjusting ring shall be locked by the locking cylinder, otherwise it is not allowed to start.

2. After the cone crusher works for a period of time, the wear of the moving cone liner and the fixed cone liner leads to the graal increase of the discharge port. In order to ensure the proct size, it is necessary to continuously adjust the size of the ore outlet. The adjustment of the discharge port of the cone crusher is realized by means of the serrated thread rising and falling cone liner between the adjusting ring and the supporting sleeve. In order to make the tooth thread lubricated and easy to adjust and disassemble, the thread must have enough clearance.

3. Alas, another person who bought a bad proct must polish his eyes when buying equipment. Don't just focus on the cheap.
4. The design of the feeding port is good, and there will be no big change. The discharging port is adjustable. Through the up and down adjustment of the moving cone, the size of the discharging port can be changed. Don't forget the cone crusher.

7. The size adjustment of the discharge port of the cone crusher is mainly realized by means of the serrated thread rising and falling cone liner between the adjusting ring and the supporting sleeve of the equipment. There is a support sleeve on the upper part of the conical broken body, which tightly connects the surrounding springs with the body. The support sleeve has a serrated thread, and the adjusting ring with a fixed umbrella plate is screwed into the thread. By rotating the adjusting ring, the fixed umbrella plate can rise or fall along the height direction, and the size of the discharge port can be adjusted
2. Inspection after adjustment
after adjusting the discharge port of cone crusher, the steel wire shot put method can be used to measure the size of discharge port. That is, the adjusting ring is gently lifted, and the cone crusher is twisted at the same time to put the shot into the crushing cavity, and four relative positions along the circumference of the crushing cavity are used to measure whether the discharge port adjustment is accurate. When the adjusted discharge port meets the size requirements, the adjusting ring must be locked by the locking cylinder before the cone crusher can be started again
3. Precautions
when adjusting the discharge port, it should be noted that the size of the discharge port must not be less than the specified size. If in the process of adjustment, it is difficult to rotate the adjusting ring e to the blockage of the thread, then it is necessary to add lubricating oil for lubrication. If there is no lubricating oil at the processing site, let the cone crusher send a small amount of ore first, and then turn the adjusting ring

8. Jaw crusher will have a process of extrusion and opening when it works. In short, extrusion is mainly crushing, opening, discharging and blanking. In the discharging process, a part of the materials larger than the width of the discharging port will be discharged together. This is also the basic principle of cone breaking. Therefore, the maximum proct particle size of crusher discharge is usually calculated by multiplying the width of discharge port by a coefficient.
9. There are three reasons for the uneven discharge of the crusher:
1. Unqualified feeding
1. Too large and hard material particles. When there are too large or hard materials in the crushing chamber, the particle size segregation of the materials in the crushing chamber of the cone crusher will be serious, and the input materials can not be completely broken, resulting in uneven discharge
2. The material contains too much water. When the materials with excessive water content enter the crushing cavity of cone crusher, they will stick together, causing the material blockage in the crushing cavity, recing the crushing capacity of the equipment to the materials, thus causing the phenomenon of uneven discharge
2. Incorrect feeding
1. Excessive feeding. When too much material is put into the crushing chamber, it is easy to block the material in the crushing chamber, occupy part of the space in the crushing chamber, rece the crushing space, and the particle size of the crushed material may be uneven
2. Uneven feeding. The uneven distribution of feeding materials around the crushing cavity of cone crusher will make the unilateral force of the equipment uneven, affect the crushing effect of the equipment on materials, and cause the phenomenon of uneven crushing materials
Third, the parameters are not correct
1, the size of the ore outlet is not appropriate. When the size of the cone crusher discharge port is not appropriate, it is easy to cause that the broken materials can not be discharged in time, resulting in material blockage, affecting the material crushing situation, aggravating the material blockage, resulting in uneven material crushing
2. The voltage is too low. When the working voltage of the crushing site is too low, it can not provide proction conditions for the normal crushing of the cone crusher, and the crushing power is insufficient, resulting in the uneven particle size of the crushed procts
how to deal with the uneven discharge of crusher
1. Connect the motor circuit correctly. The motor circuit is connected reversely, which causes the machine to reverse (the movable jaw rotates clockwise), or the motor is connected in a triangle way into a star way. This phenomenon is more common. When connecting the circuit before the test run, we must recognize the direction of the circuit and connect it correctly, which can effectively avoid this phenomenon< 2. Adjust the jaw plate. When the position of the jaw plate changes, it is easy to cause the tooth top to be opposite to the tooth top. At this time, it is necessary to adjust the jaw plate to improve this phenomenon
3. Replace worn parts. The clearance between the movable jaw and the bearing is too large after wear, which makes the outer ring of the bearing rotate relatively. To solve this problem, it is necessary to replace the bearing and movable jaw, or adopt other feasible methods to repair the wear between movable jaw and bearing, so as to rece the clearance between movable jaw and bearing, and change the discharge particle size< 4. Adjust the discharge port. If the size of the discharge port is not suitable, it can be adjusted by adjusting the gasket, wedge, hydraulic or support device until it meets the requirements
5. Analysis of material properties. In view of this problem, before crushing operation, it is better to read the operation manual carefully to understand the maximum hardness and toughness of materials that can be crushed by jaw crusher. If the nature of the material does not conform to the specification, it is necessary to select another suitable equipment for crushing.
