3. After starting, if any abnormal conditions are found, stop the machine immediately. Restart only after the cause is identified and the hazard is eliminated.
(III) Maind Operation of the Jaw Cer
1. Feeding can only begin after the cer is running normally.
2. The material to be ced should be added uniformly into the cing chambvoiding side feeding to prevent sudden load changes or unilateral load surges.
3. Under normal working conditions, the temperature rise of the bearings should not exceed 35℃, and temperature should not exceed 70℃; otherwise, stop the machine immediately to identify the cause and eliminate the issue.
4. Before stopping, feeding must be stopped firstit until the material in the cing chamber is completely discharged before shutting off the motor.
(IV) Lubrication of the Jaw Cer
1. Pay constant attention to and ensure timelybrication of the friction surfaces to guarantee normal operation and extend service life.
2. The lubricating grease used should be determined based on the usage location and temperature conditions; generally, clcium-based, sodium-based, or calcium-sodium-based greases can be used.
3. The grease added to the bearing housing should be 50-70% of volume, and it must be replaced every three months. When changing the oil, clean the dirt from the bearings and bearing housing with clean gasoline or kerosene.
4. Lubric grease must be added to the contact area between the toggle plate and the toggle plate pad before starting the machine.
Maintenance Rules and Maintenance of Jaw Cers
Maintenance of jaw cers is crucial, as maintenance and upkeep are important forny machine.
1. Lubrication of Jaw Cers
(1) Regular attention to and timely lubrication of friction surfaces can ensure the normal operation of the machine and extend its sevice life.
(2) The grease used for jaw cers should be determined based on the location and temperature conditions; generally, calcium-based, sodium-based, and calcium-sodium-based greas are used.
(3) The grease added to the bearing housing should be about 50% of its space volume, and it should be replaced every 3 to 6 hen changing the oil, the raceways of the roller bearings should be cleaned with clean gasoline or kerosene.
(4) Before starting the jaw cer, an appropriate amount of gse should be injected between the thrust plate and the thrust plate support.
2. Repair of Jaw Cers
To ensure the normal operation of the jaw cer, in addition to correct operation, plannedtenance must be carried out, which includes daily maintenance inspections, minor repairs, medium repairs, and major repairs.
(1) Minor Repairs: Main contents include checking and repairing adjustms, adjusting the discharge opening gap, and reversing or replacing worn liners. Checking the transmission parts and lubrication system, and timely replacing lubricating oil, etc. The cycle for mr repairs is about 1 to 3 months.
(2) Medium Repairs: In addition to the work of minor repairs, this includes replacing thrust plates and liners, and checking aring bearing shells, etc. The cycle for medium repairs is generally about 1 to 2 years.
(3) Major Repairs: In addition to the work of medium rhis includes turning eccentric shafts and toggle shafts, casting Babbitt metal on the upper part of the connecting rod head, and replacing or repairing various worn parts. The cycajor repairs is generally about 5 years.
3. In the daily operation of the jaw cer, regular machine inspections must be conducted. When starting or shutting down the machine, pay to checking the inside of the cer to see if there is any wear. The main points of focus include the center feed pipe, cone cap, upper and lower flow channel linerthe impeller, circular guard plate, and wear blocks, checking whether they are worn and the degree of wear. Severely worn parts must be replaced in a timely manner, and attenmust be paid to the size and type of the parts when replacing them. The drive belt of the jaw cer must be checked regularly; the drive belt is an important part that drives achine. What issues should be noted when checking the drive belt? Issues such as whether the belt is too loose or too tight, and whether the tension is uniform, etc. [ating Method
1. Jaw Cer No-load Test Run
(1) The jaw cer shall run continuously for 2 hours, and the tempture rise of the bearings shall not exceed 30℃.
(2) All fasteners shall be secure with no loosening.
(3) The flywheel and pulley shall n smoothly.
(4) All friction parts shall be free from scoring, flaking, and grinding, and there shall be no abnormal noise.
(5) The discharge opening adjustment device l ensure the adjustment range of the discharge opening.
2. Jaw Cer Loaded Test Run
(1) The jaw cer shall not produce periodic or significant impact or collision sou The maximum feed size shall comply with design specifications.
(3) Continuous operation for 8 hours, and the temperature rise of the bearings shall not exceed .
3. Preparations Before Using the Jaw Cer
(1) Carefully check whether the lubrication of the bearings is good and whether there is sufficient grease at the thrust plate conection.
(2) Carefully check whether all fasteners are tightened.
(3) Carefully check the condition of the drive belt. If damage is found, it should be replaced immediate If there is oil contamination on the belt or pulley, it should be wiped clean with a cloth.
(4) Check whether the protective devices are in good condition. If any unsafe cons are found, they must be eliminated immediately.
(5) Check whether there are any ores or debris in the cing chamber. If there are ores or debris, they must be clut to ensure the cer starts with an empty chamber.
(6) Check whether the jacking bolts are retracted, the gasket pack is compressed, and the T-bolts ae tightened. The cer operator must be trained to achieve the "Three Understands" (understand structure, performance, and principle) and "Four Can-Dos" (can ue, maintain, service, and troubleshoot), and obtain a certificate after passing the training and examination before being allowed to operate.
Article 2: Cooperate closely with the scraper conveyor ope the working face and the belt conveyor operator in the transport roadway, and maintain unified signal communication. Start and stop in sequence. If large lumps of coal or gangue pile up overflow at the cer inlet, stop the working face scraper conveyor. If large lumps of coal or gangue cannot enter the cer or if metal objects are present, the machine mus stopped for handling.
Operating Instructions
1. Depending on usage, a protective cover should be installed above the cing hopper to prevent flying stones from injuring pl.
2. Before starting the machine, clear debris from inside and around the cer, inspect all lubrication points, and manually rotate the mechanism several times to ensure flexibility before startinDo not reach into the jaw plates to remove stones while the cer is operating; use tools such as pry bars or iron hooks to address any faults.
4. If the machine stops dueterial blockage in the cing chamber, immediately shut off the motor and restart only after the material has been completely cleared.
5. When adjusting the discharge opening, first loosen the tightening springs. After adjustment, readjust the spring tension and tighten the bolts to prevent the liners from falling off during operation.
6. While the cer is operating, prevent stones from lo the tension springs, as this may affect spring strength.
