Analysis of Causes of Raw Material Loss in Concrete Mixing Station and Corresponding Prevention
Mar 25, 2019
In the concrete mixing station, the raw material is a ring that can not be ignored in the whole mixing station. The loss of raw materials affects the production cost of the whole mixing station, which greatly increases the production expenditure of the mixing station. Below, Lianhua came to talk about the reasons for the loss of raw materials in the mixing station and what are the corresponding preventive measures?
First, when the raw materials arrive at the station, the weighbridge is inaccurate, and the weighing number is too large, resulting in overweight materials.
Precaution:
1. Regularly weigh the scale to ensure accurate weighing of the weighbridge.
2. The weighbridge weighs the minimum amount as the actual weight compared to the number of bills supplied.
3. When the raw materials are put into storage, the storage loss is caused by the driver's reason, the site reason and the equipment. If the sand and gravel are not discharged after entering the site, some sandstone is not put into the warehouse. When the powder is put into the tank, some of the powder is from the tank top. overflow.
Precaution:
1. The receiving personnel should require all the drivers of the gravel truck to cut the materials at the designated place, and notify the installer to timely collect the sand and gravel outside the warehouse.
2. The mechanics should regularly check the dust removal device of the powder tank and replace the damaged air filter in time.
3. The receiving personnel should require the powder truck driver to use the appropriate pressure when flushing the tank. If the pressure is too high, a large amount of powder will overflow from the tank top.
4. When the material is used, the mixing scale of the mixing building is inaccurate, and the weighing number is too small, resulting in the computer consumption of the computer is lower than the actual consumption.
Precaution:
The concrete mixing station shall be regularly weighed according to the regulations. The operator, the production engineer, the technician and the material supervisor shall sign and confirm at the scene to ensure the accuracy of the weighing scale.
Fourth, the inventory is not timely, inaccurate, resulting in unrealistic inventory data.
Precaution:
1. Material inventory must be carried out every week and every month. After the inventory standard has been verified by the material department repeatedly, consistency should be maintained to prevent the inventory data from being distorted due to the change of the inventory standard.
2. Require the material supervisor to prepare a weekly report on the material according to the data consumption, purchase, inventory and other data on a weekly basis, and find out the problem in time to prevent the problem from expanding.
