Equipment use instructions
1. DMJ-106 series crawler mobile jaw crushing station equipment can only be used in the open air environment. Any other use of this equipment is contrary to its intended purpose.
2. DMJ-106 series crawler mobile jaw crushing station is specially used for gravel. Do not let large pieces of steel or similar unbreakable objects enter the crushing cavity, such as bucket teeth of excavators, thicker and longer steel bars, and other large unbreakable sundries, etc. It is very important to clean up large pieces of metal and other foreign objects in advance, otherwise it will cause serious damage to the equipment.
3. If the crushed raw materials contain wood, plastic, cloth, various wire harnesses, snakeskin bags, ropes, iron wires and other foreign objects, it will cause the production capacity of the equipment to decrease and cause the blockage of the screen holes of the subsequent crushing and screening equipment. , The winding of the running parts will cause serious damage to the equipment. Please pay attention to clean up the unbreakable sundries in the raw materials in time.
4. If the equipment is not operated according to the recommended application range and operating parameters described in the safety manual, the warranty will be voided, and Shanghai Dongmeng is not responsible for any damage caused by such circumstances.
5. The risks arising from the misuse of the device are solely the responsibility of the user.
Inspection before start-up
1. Before the production of the equipment, please confirm that the host is placed basically horizontal, stable, unstable, and working in an inclined state will aggravate the wear and tear of the internal components of the equipment and even cause damage to the equipment.
2. Confirm that the jaw crusher motor tooth plate, fixed tooth plate, lining plate, etc. are in good condition, and there is no foreign matter or accumulated material in the crushing cavity. Check that the jaw crusher body is connected, positioned with the frame, and the belt drive mechanism is in normal condition.
3. Check to confirm that the lining plate and grate bar of the feeder are in good condition, and check that the connection of the receiving hopper, the elastic support of the feeder, and the related working positioning are normal.
4. Check the status of waste conveyor and main belt discharger.
5. Check the working positioning and connection status of each component.
6. Check the sealing condition of the lubricating device for oil leakage, whether there is dust entering, whether the oil quality is good, and the amount of lubricating oil is appropriate.
7. Check the sealing condition of each place, whether there is leakage of material or ash, and whether the inspection door and inspection hole are sealed tightly.
8. Check whether each control device is in good condition.
9. Confirm that the power supply voltage of the device is normal.
10. Various safety facilities and lighting facilities to ensure equipment and personal safety.
11. Confirm whether the instruments are in good condition and whether the signal is normal.
12. Confirm whether the position of the circuit switch is in a ready state; confirm that the metal part of the body is reliably grounded.
13. Confirm the conditions of the materials to be crushed, the particle size of the materials, the moisture content, the sundries, and the storage capacity.
14. In order to maximize the performance of the equipment, please control the soil content in the raw materials to be less than 5% and the moisture content to be less than 10%.
15. Confirm the feeding situation, feeding method and feeding capacity of the materials to be crushed.
16. Implement the transfer situation, transfer method and transfer capacity of finished materials.
Inspection during production run
1. Check whether the transmission mechanism of the jaw crusher operates normally.
2. Check the working conditions of the bearings of each operating mechanism, whether the temperature rise and lubrication are normal.
3. Check whether the conveyor belts are free of deviation, whether the rollers are running normally, and whether there is abnormal noise and friction.
4. Always check the operating status of each mechanism, and pay attention to the current indication value. When it is found that the current of the main engine exceeds the specified value, the feeding speed should be reduced, the feeding particle size should be reduced, or the machine should be stopped immediately.
5. According to the material situation, adjust the feeding amount at any time to prevent blockage or motor overload.
6. Check the flow of materials in each part, deal with blockage and overflow in time, and ensure smooth and safe flow.
7. Check whether the instruments are in good condition and whether the signal lights are normal.
8. Check various safety facilities and lighting facilities to ensure equipment and personal safety.
9. If any abnormal situation is found, it will be stopped in time for processing.
Mandatory regulations for initial operation and maintenance of new equipment
1. After the equipment arrives at the site after long-distance transportation, it is necessary to check whether the connecting bolts are loose and falling off; whether the parts are missing or missing, it is necessary to check whether the electrical connecting bolts are loose, whether the line is falling off, and whether there is any collision damage during transportation. Tighten the bolts and reconnect the lines first.
2. After the initial feeding and running of the equipment for two hours, it must be stopped to check whether the connecting bolts are loose or falling off; check whether the fixed pressure block and bolts of the counterattack hammer are loose, check whether each bearing is heated; check whether the conveyor belt is free of abnormal friction and friction. Heat; whether there is any leakage in the joints of each pipeline, whether the lubrication is good, whether the hydraulic pipeline and electrical circuit collide and rub against the vehicle body and running parts.
3. The equipment must be shut down after the initial feeding and running for eight hours to check whether the connecting bolts are loose or falling off; check whether the fixed pressure block and bolts of the counterattack hammer are loose, check whether the bearings are heated; check whether the conveyor belt is free of abnormal friction and friction. Heat; whether there is leakage of each pipeline joint; whether the tension of the motor V-belt is appropriate. Repeat checks must be performed every eight hours of work or a shift thereafter.
Daily inspection and maintenance
1. When the equipment is shut down for a long time or when personnel routinely overhaul and maintain the equipment, the main power switch must be disconnected, the power supply of the whole machine must be cut off, and corresponding warning signs must be hung to prevent other people from accidentally touching the switches and buttons to cause serious casualties caused by equipment actions. !
When the equipment operation test is really needed in the maintenance process, a special person must supervise and confirm and issue instructions, and the equipment can be started only after the safety of the personnel and equipment has been confirmed.
2. When the equipment is overhauled and maintained, when the maintenance personnel must enter the rotating parts or the inside of the equipment, the main power supply must be cut off, the warning signs must be hung, the personnel on duty must be kept, and the materials and sundries that may fall must be cleaned. Restrict the rotating parts to prevent the equipment from rotating or starting due to unexpected situations, causing personnel to be involved in the equipment and causing serious safety liability accidents.
If the equipment is out of use for a long time and is unattended, please lock all protective doors to prevent man-made damage.
3. According to the actual use time of the equipment and the actual use environment of the site, the list of inspection items includes but is not limited to the items involved in this chapter.
