Requirements of weighing equipment for small concrete batching plant

 Used to concrete raw materials equipment called concrete weighing equipment.Weighing equipment is an important part in production of small concrete batching plant concrete, because of the concrete is a mixture of specific materials according to certain proportion, therefore, each composition materials weighing, the more accurate, more can guarantee the quality of concrete mix and save raw materials.

The weighing equipment can according to the volume of quantitative, according to the weight to quantitative, modern large-scale engineering concrete mixing plant equipment weighing equipment is according to the quality of raw materials weighing.

Weighing equipment according to the different methods of operation is divided into manual equipment and automatic equipment.When using the manual weighing equipment, the worker labor intensity big, poor working conditions, the measurement is not accurate.Using automatic weighing equipment, such as automatic balance, electronic scale, greatly improve the working conditions of the workers and saves manpower and time, at the same time guarantee the quality of the product.Automatic weighing equipment is the development direction of concrete modernization construction, the rapid development of electronic industry, has provided the safeguard for the application of automatic weighing equipment to promote.

The basic requirements of weighing equipment for small concrete batching plant:

1, batching accuracy or error should meet the requirements of concrete construction technical specifications. Generally, the accuracy of the weighing device can reach 0.5%, but due to the impact of the falling of material and the distance between the feeding device and the bucket, the weighing can not reach such accuracy. It is generally stipulated that the weighing error of various materials is material quality: cement 1%, water 1%, coarse and fine aggregate 2%, additive 1%.

2, weighing quickly, weighing machine can weigh most every time, should be greater than concrete mixer to the requirement of the material at a time, the concrete mixer from idle due to waiting for the ingredients.

3, in order to adapt to the preparation of a variety of label concrete, weighing equipment should be able to quickly change the weighing component.

4, the structure of the weighing machine should strive to simple, firm, operating, convenient adjustment, reliable work.
