Maintenance


Concrete mixing plant is a combination of machinery and equipment specialized in the production and processing of concrete. In addition to cement, sand and gravel, fly ash, etc., its raw materials also need a batch of retarders, water reducers, mold release agents, antifreeze, etc. Additives, the management of these raw materials in the production process also need to pay attention to some problems.

1. Sand and gravel management

In the sand and gravel silo of the concrete mixing station, different specifications of sand and gravel should be stacked in separate silos, and marked with the name, variety, specification, origin and date of purchase of the raw materials. The warehouse manager uniformly numbered the sand and gravel silos, and after drawing the regional distribution map of the entire yard, he notified the laboratory, the main control room, and the forklift feeder respectively, and cooperated with the above personnel to jointly determine the warehouse number on the batching scale, and record the storage situation .

2. Management of powdered materials

For powdery materials such as cement, fly ash, and ultra-fine powder, the warehouse manager of the mixing station shall uniformly number the raw material silo. The inlet of the silo should have the same logo as that of the silo, indicating the variety, specifications, and the date of purchase of the place of origin, the inventory volume, etc.; the entrance of each silo should be locked, and a special person should be responsible for the incoming management, and the powdery materials should be put into the warehouse. The silo must be checked and signed by both the receiver and the supplier before the silo can be opened to prevent errors in the feeding process and cause quality accidents.

3. Management of additives

Powder bag admixtures should be neatly stacked in the warehouse, and their name, variety, specification, place of origin, and date of purchase should be marked with a sign: liquid admixtures should be stored separately for different manufacturers and varieties, and clearly marked.
