注意事項

（1）破碎機正常運轉后，方可投料生產。

（2）待碎物料應均勻地加入破碎機腔內，應避免側向加料或堆滿加料，以免單邊過載或承受過載。

（3）正常工作時，軸承的溫升不應該超過30℃，很高溫度不得超過70℃。超過上述溫度時，應立即停車，查明原因并加以排除。

（4）停車前，應先先停止加料，待破碎腔內物料完全排出后，方可關閉電源。

（5）破碎時，如因破碎腔內物料阻塞而造成停車，應立即關閉電源停止運行，將破碎腔內物料清理干凈后，方可再行起動。

（6）顎板一端磨損后，可調頭使用。

（7）破碎機使用一段時間后，應將緊定襯套松動而損傷機器。

maintenance methodas

1. Lubrication of jawcruasher

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

(2) The lubricating grease used for jawcruashers should be determined according to thelocation of use and temperature conditions. Generally, calciumbased, sodium based, and calcium sodium based lubricating greasesare used.

(3) The lubricating grease added to thebearing seat is about 50% of its spatial volume and should bereplaced every 3-6 months. Clean the raceway of the roller bearingwith clean gasoline or kerosene when changing theoil.

(4) Before starting the jawcruasher, an appropriate amount of lubricatinggrease should be injected between the thrusta plate and the thrust a plate support.

2. Maintenance of jawcruasher

To ensure the normal operation of the jawcruasher, in addition to correct operation, plannedmaintenance must be carried out, including daily maintenancechecks, minor repairs, medium repairs, and majorrepairs.

(1) The main content of minor repairsincludes checking and repairing adjustment devices, adjusting theclearance between discharge ports, and turning or replacing wornlining a plates. Check the transmission part, lubricationsystem, and replace lubricating oil in a timely manner. The cycleof minor repairs is about 1-3 months.

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

(3) In addition to carrying out intermediaterepairs at the major repair department, it also includes replacingand turning eccentric shafts and jaw shafts, castingBababitt alloy on the upper part of theconnecting rod head, and replacing or repairing worn parts. Theoverhaul cycle is generally around 5 years.

The causes and troubleshootingmethodas of jaw cruasher faults

Troubleshootingmethodas forthe causes of faults

1. The flywheel rotates but the moving jawstops swinging. 1. The thrust a plate is broken

2. Damaged connecting rod

3. Spring fracture 1. Replace thethrust a plate

2. Repair the connectingrod

3. Replace the spring

2. Loose teeth a plate, metal impact on teetha plate fixing screws or side wedges, loose fasteningor 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 orthe bearing contaect is poor or the bearing is damaged. 1. Addnew lubricating grease. 2. Adjust the tightness of the bearing orrepair the bearing seat tile or replace thebearing

4. The particle size of the product becomescoarse, and the lower part of the tootheda plate is significantly worn. Adjust thetoothed a plate or adjust the dischargeport

5. The thrust a 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 supportseat

6. When the spring breaks and the dischargeport is not loosened, the spring should be loosened first, and thenthe pull rod nut should be tightened appropriately afteradjustment

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

precautions

(1) The cruasher can onlay be put into production after normaloperation.

(2) The materials to becruashed should be evenly added into thecruasher chamber, and lateral feeding orstaecking of materials should beabvoided to prevent one-sided overload orbearing overload.

(3) During normal operation, the temperaturerise of the bearing should not exceed 30 ℃, andthe maximum temperature should not exceed 70 ℃. Whenthe above temperature is exceeded, the vehicle should be stoppedimmediately, the cause should be identified andeliminated.

(4) Before parking, the feeding should bestopped first, and the power can onlay be turned off after the material in thecruashing chamber is completelydischarged.

(5) When cruashing, if the vehicle stops due to materialblockage in the cruashing chamber, the power should be immediatelyturned off and the operation should be stopped. After cleaning thematerial in the cruashing chamber, it can berestarted.

(6) After one end of the jawa plate is worn, it can be used with an adjustablehead.

(7) After using thecruasher for a period of time, the tighteningsleeve should be loosened and the machine should bedamaged.
