The plate chain bucket elevator is bigger, but it also needs to be tested in two stages when testing the machine, so the two stages are: no-load experiment with no materials loaded, and the other is a load test with materials loaded. The following Let me tell you in detail!
1. Plate chain bucket elevator no-load trial operation;
(1) Check whether there are tools, iron parts or other sundries in the hoist, and clean them up if necessary;
(2) The guide rail, reducer and transmission chain of the rear bearing seat should be fully lubricated;
(3) Check whether the parts of the plate chain bucket elevator are in good condition and whether the tension of the traction chain is appropriate.
(4) After the above preparations are completed, turn the trolley by hand to observe the friction force of the traction chain. When there is no fault, the power can be turned on and the crane can be started several times. If it can run, the bucket elevator can run continuously.
(5) Debugging must be carried out under unified command to avoid confusion during debugging. Parking guards must strictly abide by the rules and must not leave their posts without permission.
(6) Special personnel should be assigned to observe and operate the main parts of the head, tail, and middle, and report problems in time.
(7) The loading test can only be carried out when the empty vehicle runs for 2 hours and the operating conditions are satisfactory.
(8) Cover all inspection covers and place sufficient asbestos or other gaskets on them to allow for load testing.
2. Test and operation of lifting equipment:
(1) Start with no load first, after normal operation, gradually feed the material, strive for uniformity, and do not feed suddenly to avoid blockage or overload. Don't load things before driving.
(2) During debugging, the housing should be completely sealed to prevent the material from falling off. Before stopping, all materials in the elevator hopper should be unloaded.
(3) During the trial operation (no-load test and load test), the prepared data such as voltage, current, power, link speed, and lifting capacity must be tested to check whether the design requirements are met. Does the bucket elevator have the phenomenon of returning material and how does it vibrate?
The above is the test program before the plate chain bucket elevator is officially put into use, I have already told you. Hope all bucket elevator users can understand the importance of debugging.

Batching plant bulk material transfer scheme
In batching plant systems, assembled steel silos are often required as intermediate storage containers for ingredients. Bulk materials are transported to these assembled steel silos by bulk trucks, belts, etc., and then conveyed to the weighing scales via screw conveyors, belt conveyors, etc., for mixing.
Factory Bulk Material Storage and Conveying Solutions
Factory bulk material storage and conveying solution: Raw materials arrive at the factory by bulk trucks or other means, and are conveyed to the raw material storage silo via dump-lift or compressed air. They are then transported to the metering equipment via belt conveyor or screw conveyor. After precise metering, they are mixed or bagged, and sent to the finished product storage silo via discharge equipment, or bagged for sale after packaging by an automatic packaging and palletizing machine.
Hydropower project bulk material transfer scheme
New hydropower projects are usually built in relatively remote areas, making it difficult to transport raw materials such as cement, fly ash, and sand and gravel. Large-capacity prefabricated steel plate silos are usually needed for centralized transportation, allowing for a single delivery to cover a longer period. The materials are then directly transported to the point of use via inclined belts, pneumatic conveying, and other methods.
Train Bulk Material Transfer Scheme Diagram
Bulk materials are delivered to the site by train, and then transported via pneumatic conveying/belt conveying/screw conveyors and elevators, etc., to assembled steel silos for storage. From there, they are distributed to various locations in the region by tanker trucks, or connected to a bagging machine for sale as bagged materials, or transported by truck to the point of use.
Port Bulk Material Transfer Station Solution
Bulk materials arrive at the terminal by water, and are then transported to assembled steel plate silos for storage via pneumatic conveying, belt conveying, ship unloaders, bulk truck transfer, chutes, elevators, etc. Afterwards, they are distributed throughout the region by cement tankers or connected to packaging machines for sale as bagged materials.
Mine Bulk Material Storage and Transportation Solution
Ore raw materials are transported through mining to raw material storage silos or stockyards, then transported via conveyor belts to crushing machinery (coarse crushing, fine crushing), and then transported by belt conveyors/hoists or other means to finished product storage silos or processing equipment, finally transported by truck or packaged for sale. If necessary, the crushed granular material is then ground into powder by a pulverizer and transported to the finished product warehouse, then sold via bulk trucks or after packaging.
