Dual Shaft Shredder

Operation Instruction

General Provisions

The first reprint machine, shredder driver must be trained, to achieve the “three understanding” (understand the structure, understand the performance, understand the principle), “four” (will use, will maintain, will maintain, will deal with the fault), after the training test qualified, obtain a certificate, quasi post operation.

Article 2 Cooperate closely with the scraper conveying driver of the working face and the belt conveyor driver of the transportation lane, make unified signal contact, and start and stop in order. When large lump coal and gangue are accumulated and spilled at the feed port of the crusher, the operation of the scraper conveyor should be stopped. If there are large lumps of coal, gangue cannot enter the broken plane or there are metal objects, it must be shut down for treatment.

Preparation Work

1. Tools: wrench, pliers, screwdriver, hammer, spade, etc.

2, necessary spare parts: all kinds of short chain, chain link, bolts, nuts, crusher insurance dowel, etc.;

3. Lubricating oil and turbine oil

Treatment of inspection

1, motor, reducer, hydraulic coupling, head, tail and other parts of the connection must be complete, intact, tight. Reducer, hydraulic shaft joint should have no oil leakage, oil leakage, oil quantity should be appropriate.

2, signal must be sensitive and reliable, no signal is not allowed to start. Make sure the spray sprinklers are in good condition.

3. Power cables and operation lines must be hung neatly without being squeezed;

4, the coal, gangue, sundries near the nose and the coal dust of the motor and reducer must be cleaned;

5, face scraper conveyor head and reprint machine tail lap to be suitable;

6. The scraper chain plate is of moderate importance, and the scraper and screws must be fully fastened;

7, reprinting machine walking trolley must be stable and reliable;

8. When the machine is partly turned on, the operation of each part should have no abnormal sound, and the scraper, chain and connecting ring should have no torsion, twist and bend deformation;

9. The roadway support at the shredder and shredder must be intact and firm.

10, the safety protection net and protection device of the crusher, to ensure that no deformation no failure, safe and reliable;

11. The roadway support of the reprinting machine and the shredder must be intact and firm.

Precautions

Trial run

1. Switch on the power grid switch;

2. Manually press the click button for the trial run of the machine;

3. Start and idling for 1 ~2 weeks;

4. Joint operation of reprinting machine and shredder;

5. Check that there is no abnormality and send a startup signal.

6, the operation of the machinery and motor should be no vibration, sound and humidity should be normal, the bearing temperature should not exceed 75℃, motor temperature should not exceed the nameplate provisions.

7. The chain tightness of the reprinting machine must be consistent. Under the condition of full load, the chain tightness is not allowed to exceed the length of two chain rings.

8. After the fusible plug or fried piece of the joint of the reprinting machine is damaged, wood or other materials shall not be used instead.

9. The safety device of the protective net of the crusher should be kept in good condition, and should be checked frequently in the working process. If there is any damage, it should be stopped immediately.

10, reprinting machine tail protection and other safety devices must be ensured intact.

11, transfer and transfer machine.

(1) Clean the floating coal and gangue in the tail, on both sides of the fuselage and under the bridge;

(2) Protect cables, water pipes, oil pipes, and hang them neatly;

(3) Check the roadway support, and push the reprinting machine under the condition of ensuring safety;

(4) The walking trolley and the tail frame of the belt conveyor should have good contact, do not run off, and have good lap after moving, prevent large plastics from hurting the tape, and ensure smooth coal flow;

(5) After the transfer machine, the nose and tail should be kept flat, straight and stable, and the jack live rod should be recovered.

Operation Attention

1, plastic crusher and power unit to install firmly. If need long-term fixed operation, plastic crusher should be fixed on the cement base; If the plastic crusher is needed for mobile operation, the unit should be installed on a base made of Angle iron, and ensure that the power machine (diesel engine or motor) and the belt pulley groove of the plastic crusher are in the same rotary plane. 2. After the installation of the plastic crusher, the fasteners of all parts should be checked and tightened if they are loose. At the same time to check the belt tightness is appropriate.

3. Before starting the plastic crusher, first rotate the rotor by hand to check whether the jaw, hammer and rotor are flexible and reliable, whether there is collision in the crushing room, whether the rotating direction of the rotor is consistent with the direction indicated by the arrow of the machine, and whether the lubrication of the power machine and plastic crusher is good.

4, do not casually replace the belt pulley, in case the speed is too high resulting in the explosion of the crushing chamber, or the speed is too low affecting the working efficiency of the crusher.

5. After starting the plastic crusher, it should be kept idling for 2~3min, and then feeding after there is no abnormal phenomenon.

6, the work should always pay attention to the operation of the plastic crusher, first of all, the feeding should be uniform, to prevent blocking the crushing chamber; Second, don’t overwork for a long time. If there is vibration, noise, bearing and body temperature is too high, spraying material and other phenomena, should immediately stop the machine for inspection, troubleshooting before continuing to work.
