How to adjust the discharge port of cone crusher in Liming

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. After the adjustment, 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.

3. There are several ways to adjust the discharge port of jaw crusher:

gasket adjustment: put a group of gaskets with the same thickness in the rear thrust plate support and the rear wall of the frame. By increasing or recing the number of cushion layer, the discharge port of crusher is reced or increased
wedge adjustment: with the help of the relative movement of the two wedges between the rear thrust plate support and the rear wall of the frame, the adjustment of the ore discharge port of the crusher is realized. Turn the nut on the bolt to make the adjusting wedge move up or down along the rear wall of the frame, and drive the front wedge to move forward or backward, so as to push the thrust plate or movable jaw, so as to achieve the purpose of adjusting the ore outlet
hydraulic adjustment: in recent years, it is necessary to install a hydraulic cylinder at this position to adjust the discharge port. The safety device is a kind of safety measure which is used to effectively prevent the machine parts from being damaged when the crushing cavity of jaw crusher enters into non crushing objects. The most commonly used is to use the rear thrust plate as the safety device of the crusher. The jaw crusher adopts hydraulic safety device, which is reliable, safe and easy to discharge faults

supporting device refers to the bearing part of jaw crusher. Generally, large and medium-sized crushers adopt sliding bearing cast with Babbitt alloy, which can bear large impact load and is relatively wear-resistant, but its operation efficiency is low, so it needs forced lubrication. With the improvement of rolling bearing manufacturing technology, rolling bearings will be used in large jaw crushers in the future

4. Alas, another person who bought a bad proct must polish his eyes when buying equipment. Don't just focus on the cheap.

5. 1. Before starting the machine, check whether the screws are loose, whether there are obstacles around the motor equipment, whether there are ores or debris in the crushing chamber, correct the tension of the belt, and fasten all spring screws
2. Check whether the clearance of the discharge port meets the requirements. The discharge port should be adjusted according to the particle size of the material, not too large or too small
3. When the oil temperature reaches 25-30 ℃, start the oil pump motor for 5-10 minutes, observe the working condition of the lubrication system, and observe that the oil return pipe is normal and the oil quality meets the requirements before starting the main motor
4 www.sbmyuanzhuipo.net The feeding can be started only after 1-2 minutes of no-load operation. The feeding should be uniform and continuous. The non breakable materials must not be sent into the crusher. If there is any abnormal noise, stop the machine immediately for inspection
5. Stop feeding before shutdown, and stop the machine after all the materials are discharged.

6. 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 gyratory crusher was first used in 1898. Because of its reliable operation and large proction capacity, it is still widely used in mineral processing plants and other instrial departments. Its specification is expressed by the width of feeding mouth and discharging mouth. For example, Model 500 / 75

8. The factory setting is a way to adjust the rear pull rod spring device to increase or decrease the size of the discharge port

9. The unstable operation of moving cone, also known as moving cone overturning, refers to a series of abnormal motion states, such as the beating and overturning of the moving cone in the spherical bearing ring the operation of the crusher e to the problems in the process of design, manufacture or installation adjustment of the cone crusher. When the cone crusher is in normal operation, driven by the eccentric shaft sleeve, the axis of the moving cone moves around the center line of the frame, and the distance between the moving cone liner and the fixed cone liner graally decreases from large to small, and then increases from small to large, so as to achieve the purpose of crushing materials. When crushing materials, the moving cone will rotate in the opposite direction of the eccentric shaft sleeve rotation e to the reaction force of the materials. Therefore, the normal operation of the cone crusher is to crush the materials in the way of "rotary extrusion", so that the size of the crushed materials in the three-dimensional direction is roughly the same. In addition to the structural reasons of the materials themselves, there are few needle flakes.

10. The cone crusher body is composed of an upper frame and a lower frame. The upper frame and the lower frame are connected by adjusting ring bolts and springs. The upper part of the machine body has a movable feeding funnel. The upper end of the spindle is made up of nuts for fixing the feeding plate, and the thrust bearing at the lower end of the spindle is composed of four parts. The big gear in the transmission gear is located at the upper end of the eccentric sleeve, and the small gear is arranged under the big gear. www.gxzxw.org
there are two ways to adjust the discharge port: mechanical and hydraulic. The mechanical adjusting device only needs to adjust the ratchet wheel installed on the column to drive the adjusting ring to drive. The hydraulic adjusting device uses two hydraulic cylinders outside the frame (four hydraulic cylinders for 10 feet) to control the claw on the top of the piston rod and the driving gear and groove teeth on the adjusting cover. The piston rod extends once and can rotate. A groove on the driving gear is provided with a spring, When the piston rod retracts each time, it can automatically and timely clamp the groove on the main drive ring, so as to keep the ore discharge port unchanged until the piston rod extends out again
in addition to the spring overload protection device, this device also has a pneumatic overload protection device. The piston rod in the cylinder of the pneumatic overload protection device usually presses the adjusting ring tightly on the frame
in order to position the fixed cone, there are two types of hydraulic locking device. One kind uses a group of small oil cylinders, no spring in the cylinder, usually rely on the spring to position the locking ring, and lock the fixed cone of the adjusting ring teeth. When adjusting the discharge port, make the oil pressure exceed the spring force, then loosen the locking ring and the fixed cone, and the fixed cone can rotate on the adjusting ring; The other uses 6-8 hydraulic columns. Usually, the fixed cone is pressed tightly by the spring in the column to make it not move. Before adjusting the discharge port, the fixed cone is released by lever control
