Used to mix the raw materials of concrete batching plant equipment called concrete weighing equipment, small concrete batching plant equipment basic weighing requirements as following:
1, the accuracy or error of ingredients should meet the requirements of concrete construction technical specifications. The general weighing device can achieve its own accuracy of 0.5%, but because of the impact of the material when the fall and the feeding device and the bucket has a certain distance and other reasons, often make weighing less than such accuracy. Generally, the weighing error of various materials is material quality: 1% of cement, 1% of water, 2% of coarse and fine aggregate, 1% of additive.
2, weighing quickly, the weighing device can weigh the maximum amount of each time, should be greater than the amount of the concrete mixer on the material requirements, so that the concrete mixer machine will not wait for the ingredients and idle.
3, in order to adapt to the preparation of a variety of standard concrete needs, weighing equipment should be able to quickly change the weighing component.
4, the structure of the concrete batch plant weighing device should be simple, strong, easy to operate, easy to adjust, reliable work.
