The roller crusher, as its name implies, its crushing principle is to use the roller of material extrusion to complete the crushing operation, therefore, the roller to roller crusher is an important part.So, the problem came, in the process of operation, on the roller crusher roller cracking how to do?

Under normal conditions of roller crusher roller wear, the appearance of the roller is not cylindrical, forming two big, small center concave outline, then the larger mud block or mud ball can be worn through the concave, play no role in breaking, so it is necessary to repair the roller.There are two methods commonly used in roller repair: local cutting (grinding) machining repair and local surfacing repair.

1. Local surfacing welding

Local surfacing welding is to weld and fill the worn groove of roller crusher.This kind of method is brief and useful, do not affect the production, and surfacing the hardness and wear resistance are better, the defect is only suitable for good weldability roller (such as cast steel roller).
 

2. Local cutting (grinding) method

Local cutting (grinding) method of operation is: on the roller crusher frame, a special tool rack, its moving track should be parallel to the roller axis.Repair start to roll crusher, with manual feed organization (conditional can also choose active feed organization) on the roller cutting.

(1) the running track of the tool rest is parallel to the axis of the roller, preventing the taper after cutting and affecting the crushing effect.

(2) control the roller speed of the crusher.Roller appearance of the linear speed should not exceed the cutting tool allowed cutting speed, otherwise should be adopted to reduce the speed to prevent damage to the tool.

(3) about the high hardness roller, cutting can not be processed, at this time can choose to grinding a head according to the cutting method for grinding processing.

3. Disassembly and repair

The repair method after disassembly is to disassemble the roller with the shaft together and apply it to the machine after repair by turning.This method has large workload, long downtime, but easy and thorough repair.

Roller crusher is a kind of crushing equipment, its feed particle size is relatively small, fine discharge particle size, mainly used in stone production line of secondary crushing, we only ensure the normal operation of roller crusher, to ensure the profit of the enterprise.

Cone crusher is a very important equipment in the crushing equipment, in the crushing, sand production line application is very frequent.Good choice of equipment is the first, the equipment is better after the installation of the more important.How much do you know about installation of cone crusher?

1. The cone crusher shall be supplied after installation by the manufacturer. After receiving the cone crusher, the user shall check and eliminate all kinds of problems arising in transportation before installation.

2. When installation, the longitudinal horizontal tolerance of the bottom plane of the frame of the cone crusher is 0.5mm/m, and the horizontal horizontal tolerance (measured on the spindle) is 0.15mm /m.

 

3. The parts on the upper part of the frame shall be assembled after leveling and straightening the frame and tightening the anchor bolts.

4. The cone crusher must be checked comprehensively before starting.The fastness of the fixed parts, the lubrication of each part and the proper tension of the triangle belt should be the focus of inspection.

5, the inspection must cut off the main circuit switch, and on the switch hanging a clear sign, marked "do not close" and other words.

6, the cone crusher must start with no load, no load test run shall not be less than 2 hours, during the test run should pay attention to observe the work of the cone crusher, if found abnormal phenomenon immediately stop, and find out the reason;The machine can be restarted after elimination.

 

7, the ore should be uniformly fed into the crushing chamber of the cone crusher by the feeder.Start load test should be given a small amount of ore, gradually transition to half-load, full.If the ore block into the crusher is too large or too much ore, or often fall into non-broken material (metal block) will speed up the wear and damage of the machine.Therefore, it is necessary to control the large piece of ore and non-broken material falling into the machine and maintain even feeding.

8. When the cone crusher is working, the stable maintenance temperature of the bearing shall not exceed 75℃. If it exceeds the temperature, the machine shall stop immediately to remove the fault.

9, cone crusher stop, should first cut off to the ore feed.After the ore in the crushing chamber is completely broken, the power supply of the main motor is cut off and shut down.

10. Centralized oil supply system is adopted for lubrication.When feeding oil, pay attention to the amount of oil on the bracket support surface.The user can also supply oil directly from the grease gun to the grease hole of the bearing.Don't waste too much.The user can adjust the oil feeder of the lubrication system to achieve the purpose of reasonable oil supply.

 

11, the discharge port of the cone crusher can be adjusted according to the specification, the user can according to the required size and the wear of the tooth plate in the work, change the number of shim in the support at any time, in order to adjust the discharge port, to obtain a satisfactory size.

Above is our company to buy cone crusher customers remind, if you still know what need to pay attention to, please leave a message with me.
