Maintenance and maintenance of aggregate supply system in concrete mixing plant

1,the work must be carried out before each class belt conveyor no-load inspection, cleaning debris, mud, etc., tightening the various parts of the screw, adjust the belt deviation phenomenon, the rotation should be flexible rotation.
2,electric drum according to the instructions required periodic oil change.
3,the use of six months after the inspection and make up the rotation of the parts at the bearing grease, after a year to conduct a full dismantling oil change.
4,the cleaning device often check the adjustment of the skin closer to the belt position, to ensure that the cleaning material is normal.

Maintenance and Maintenance of Metering System for Concrete Mixing Plant
1,each class must check the adjustment of the bucket of the soft interface, to maintain the length of the loose, to ensure that the measurement accuracy.
2,after the winter shutdown, the water supply system, the admixture of the water supply all drained.
3,admixture pump such as seasonal disabling must be backwash, to prevent the pipeline and the pump additives deposited deposition or no solvent.

The maintenance of the mixing system in the concrete mixing plant
1,each class to check the shaft seal chamber, the distributor inlet and outlet and sealing pipe is smooth, whether full of grease, the lubrication point and slow down the box whether there is enough oil (grease).
2,each class to observe the electric lubrication pump oil tank is running out of oil, close to run out in time to fill, do not allow oil-free operation.
3,each class work must be fully cleaned inside and outside the mixing cylinder, unloading doors, etc. accumulation of materials, and rinse with water, rinse the adhesive material should be chiseled regularly.
4,the mixing of the mixing blades must be tightened once a week to prevent the leaves off the cause of the accident.

Concrete Mixing Plant Equipment – Powder Supply System Maintenance and Maintenance
1,the cement must be a week of dust in the dust collector device vibration several times, the dust bag (filter rod) on the sticky ash cleared to ensure smooth running.
2,the inlet of the feed pipe wall, screw conveyor outlet must be cleaned once a week to prevent the hard lump and debris plug card and the lack of material failure.
3,do not use a long time to empty the screw inside the machine.
4,the screw conveyor head ball bearings at the middle of the bearing at the bearing every four hours must be filled with grease once, the tail gearbox for the first time to work for 500 hours, after the annual replacement of grease

Maintenance of Gas Road System in Concrete Mixing Plant
The maintenance and maintenance of the airway system is subdivided: maintenance and maintenance of the air compressor, maintenance and maintenance of the cylinder, maintenance and maintenance of the solenoid valve, maintenance and maintenance of the oil and water separator and the oil mist. As listed in the “Concrete Mixing Plant Use and Maintenance Manual”.
