The screw conveyor in a concrete mixing plant is a device that links the concrete batching machine and the cement silo. Its function is to transport the powder materials to the concrete mixer, which improves the production efficiency of the concrete plant. Generally, a single station of a large-scale concrete batching plant needs to be equipped with 4 sets of screw conveyors, while a mobile concrete batching plant, whether it is the smallest pld600 mobile batching plant or the largest yhzs75 plant, generally has two sets at most. This is mainly based on the characteristics of the mobile station: strong mobility and convenient transfer.
Attention should be paid to the following issues in the trial run of the screw conveyor of a mobile concrete batching plant:
1. The conveyor should be installed on a horizontal concrete foundation and fixed with anchor bolts.
2. Pay attention to the verticality between the main body and the horizontal when installing.
3. After installation, check whether the bolts in each part are loose and whether the door of the main engine is tight. If not, please tighten it.
4. Configure the power cord and control switch according to the power of the equipment.
5. After the inspection is completed, carry out a no-load test run, and the test run is normal and production can be started.
The maintenance of screw conveyors for concrete plant mobile batching can be done from the following points:
1. When transporting materials, do not mix in strong large particles;
2. Check the working, sealing and smooth conditions of the gearbox once a week to see if there is abnormal noise, oil leakage, etc.
3. The lack of oil should be made up in time, but it should not exceed the oil level line.
4. Check the joint fastening situation of the whole machine once a month.
5. The gearbox needs to be replaced with new lubricating oil after 100 hours of operation, and it needs to be replaced every 1000 hours in the future.
