注意事项

（1） 破碎机正常运转后，方可投料生产。

（2） 待碎物料应均匀地加入破碎机腔内，应避免侧向加料或堆满加料，以免单边过载或承受过载。

（3） 正常工作时，轴承的温升不应该超过30℃，温度不得超过70℃。超过上述温度时，应立即停车，查明原因并加以排除。

（4） 停车前，应首先停止加料，待破碎腔内物料完全排出后，方可关闭电源。

（5） 破碎时，如因破碎腔内物料阻塞而造成停车，应立即关闭电源停止运行，将破碎腔内物料清理干净后，方可再行起动。

（6） 颚板一端磨损后，可调头使用。

（7） 破碎机使用一段时间后，应将紧定衬套松动而损伤机器。

Professional Small Jaw Cer Manufacturer - Jaw Cer | Jaw CerPEX150x750

maintenance methods

1. Lubrication of jaw cer

(1) Regularly paying attention to and timely lubricating the friction surface can ensure the normal operation of the machine and extend its service life.

(2) The lubricating grease used for jaw cers should be determined according to the location of use and temperature conditions. Generally, calcium based, sodium based, and calcium sodium based lubricating greases are used.

(3) The lubricating grease added to the bearing seat is about 50% of its spatial volume and should be replaced every 3-6 months. Clean the raceway of the roller bearing with clean gasoline or kerosene when changing the oil.

(4) Before starting the jaw cer, an appropriate amount of lubricating grease should be injected between the thrust plate and the thrust plate support.

2. Maintenance of jaw cer

To ensure the normal operation of the jaw cer, in addition to correct operation, planned maintenance must be carried out, including daily maintenance checks, minor repairs, medium repairs, and major repairs.

(1) The main content of minor repairs includes checking and repairing adjustment devices, adjusting the clearance between discharge ports, and turning or replacing worn lining plates. Check the transmission part, lubrication system, and replace lubricating oil in a timely manner. The cycle of minor repairs is about 1-3 months.

(2) In addition to carrying out minor repairs in the maintenance department, it also includes replacing thrust plates, lining plates, inspecting and repairing bearing shells, etc. The maintenance cycle is generally around 1-2 years.

(3) In addition to carrying out intermediate repairs at the major repair department, it also includes replacing and turning eccentric shafts and jaw shafts, casting Babbitt alloy on the upper part of the connecting rod head, and replacing or repairing worn parts. The overhaul cycle is generally around 5 years.

The causes and troubleshooting methods of jaw cer faults

Troubleshooting methods for the causes of faults

1. The flywheel rotates but the moving jaw stops swinging. 1. The thrust plate is broken

2. Damaged connecting rod

3. Spring fracture 1. Replace the thrust plate

2. Repair the connecting rod

3. Replace the spring

2. Loose teeth plate, metal impact on teeth plate fixing screws or side wedges, loose fastening or replacement of screws or side wedges

3. The bearing temperature is too high. 1. Insufficient or dirty lubricating grease

2. The bearing clearance is not suitable or the bearing contact is poor or the bearing is damaged. 1. Add new lubricating grease. 2. Adjust the tightness of the bearing or repair the bearing seat tile or replace the bearing

4. The particle size of the product becomes coarse, and the lower part of the toothed plate is significantly worn. Adjust the toothed plate or adjust the discharge port

5. The thrust plate support pad produces an impact sound. 1. Insufficient spring tension

2. The support pad is worn or loose. 1. Adjust the spring force or replace the spring

2. Tighten or modify the support seat

6. When the spring breaks and the discharge port is not loosened, the spring should be loosened first, and then the pull rod nut should be tightened appropriately after adjustment

7. Machine jumping, loose tightening of anchor bolts or replacement of anchor bolts

precautions

(1) The cer can only be put into production after normal operation.

(2) The materials to be ced should be evenly added into the cer chamber, and lateral feeding or stacking of materials should be avoided to prevent one-sided overload or bearing overload.

(3) During normal operation, the temperature rise of the bearing should not exceed 30 ℃, and the maximum temperature should not exceed 70 ℃. When the above temperature is exceeded, the vehicle should be stopped immediately, the cause should be identified and eliminated.

(4) Before parking, the feeding should be stopped first, and the power can only be turned off after the material in the cing chamber is completely discharged.

(5) When cing, if the vehicle stops due to material blockage in the cing chamber, the power should be immediately turned off and the operation should be stopped. After cleaning the material in the cing chamber, it can be restarted.

(6) After one end of the jaw plate is worn, it can be used with an adjustable head.

(7) After using the cer for a period of time, the tightening sleeve should be loosened and the machine should be damaged.
