Operator Responsibility

●Check the silo and confirm the type and quantity of raw materials in the silo.

●Check whether the type of material entering the warehouse is consistent with the warehouse number, and prevent the phenomenon of cross warehouses.

●Check the granularity of the crushed materials into the warehouse, and report to the central controller and supervisor in time if any problems are found.

●Clean the initial cleaning and screening equipment once in each shift, and the permanent magnetic cylinder twice. The cleaned debris is bagged and placed in a designated location, and taken out of the workshop when off work.

●Monitor the operation of the equipment above the fourth floor to ensure the normal operation of the equipment, and report the abnormal situation to the central controller and the supervisor in time.

●Assist and supervise the granulator to replace the screen mesh of the grading sieve normally.

●Clean the silo, chute and distributor as required.

●Check the storage volume of each silo before the shift and fill in the silo inventory table truthfully.

●Do a good job in the sanitation of the responsible area to ensure that the ground and equipment surfaces are free from dust and stains.

●Sanitary tools are fixed and stored neatly.

Cylinder initial cleaning operation rules

 

●The operator should understand the structure of the machine and be familiar with the performance of the machine.

●Before use, it should be run empty, and the steering of the screen drum should be consistent with the direction of the steering sign.

●Check each fastener, there must be no abnormal sound such as jamming, bumping and friction.

●Material can be fed after the machine is running normally, and the feeding amount should be uniform and appropriate.

●If the machine breaks down during the working process, it should be stopped immediately for inspection, and then restarted for use after the trouble is eliminated.

●The machine cannot be overloaded, and the feeding must be interrupted before stopping, and the machine can only be stopped after the materials in the standby machine have been cleaned.

 

Bucket elevator operating procedures

 

●Routine inspection before start-up: whether the bolts, transmission devices and safety shields are in good condition.

●Check whether the tightness of the bucket bag is appropriate, and whether the bucket is loose, deformed or worn.

●Start the hoist and wait for it to run normally before supplying materials.

●The feeding amount should be uniform and appropriate.

●Regularly check the tensioning wheel on the operating base, and correct the running film of the bucket bag.

●Observe the running condition through the observation window, and stop the machine for inspection if there is any abnormality.

●Before shutting down, the feeding should be stopped first, and then continue to run for about 1 minute, and the machine can be shut down only after the material in the standby machine is empty.

●During operation, unless there are special circumstances, the load shall not be started or stopped.

●Once a blockage occurs, the material supply should be stopped immediately, and then the insert plate under the machine base should be pulled out to remove the blocked material. Note that it is strictly forbidden to reach into the machine base by hand to pick up when removing the blockage.

 

Classifying sieve operating procedures

 

●Adjustment of grading sieve

①Adjustment of the inclination angle of the screen surface: before the equipment leaves the factory, the angle between the screen surface and the horizontal plane is generally about 4°, and its size can be adjusted by adjusting the length of the steel rope (generally no adjustment is made).

②Adjustment of the pressing mechanism of the screen surface: the pressing force of the pressing mechanism can be adjusted by adjusting the length of the screw screw. Tighten the lock nut after adjusting the compression force.

●Operating rules

① Check all fasteners before starting the machine, and there must be no looseness.

②The machine starts and runs for 2 to 3 minutes, and the material can only be fed if there is no abnormal sound such as jamming, bumping, and friction.

③ The machine must not be used under overload conditions.

④ For different screening requirements, replace different screens to meet the output and quality requirements. When replacing the screen, the screen surface should be cleaned, and the damage of the screen and the wear of the rubber ball should be carefully checked. If the screen is damaged, it should be replaced or repaired in time. If the rubber ball is seriously worn, it should be replaced in time.

 

03 Workflow of warehouse workers

 

●CPC informs the raw materials (semi-finished products and finished products) to enter the silo;

●Watching warehouse workers go to the corresponding silo to check whether the raw materials (semi-finished products and finished products) are put into the warehouse correctly;

●Check whether there are raw materials (semi-finished products, finished products) entering the warehouse in the adjacent chute to prevent the phenomenon of mixed warehouses;

●Check the feeding situation of the silo according to the time requirement;

●Check whether the raw materials (semi-finished products and finished products) are qualified (sampling to central control and granulation posts);

●Check the operation of the equipment above the fourth floor, and promptly notify the central control and supervisor if any problems are found;

●Assist in granulation, central control, maintenance and inspection of equipment above the fourth floor.
