The semi-dry artificial sand production process intelligent control technology of the present invention is composed of a semi-dry sand production process technology system and an automatic control technology system. The automatic control technology semi-dry artificial sand production process intelligent control technology is mainly for There are three parts: automatic control of artificial sand fineness modulus, automatic control of stone powder content and automatic control of moisture content of finished sand; through the intelligent control technology of semi-dry artificial sand production process, it can improve the quality of project construction and reduce the cost of construction. Construction cost, solve the problem that the stone powder content, fineness modulus and moisture content of sand in sand and gravel processing cannot meet the quality standards, and ensure that various indicators of artificial sand are in a controlled state, so that the quality of artificial sand can reach that of sand for concrete optimal standard. At the same time, it can ensure the best control of the moisture content of the source of the artificial sand making material, eliminate dust pollution to the atmosphere, and protect the environment. The implementation of the invention has good economic and social benefits.
Description
technical field [0001] The invention relates to a mechanical processing technology of artificial sand and gravel, in particular to an intelligent control technology of a semi-dry artificial sand production process. Background technique [0002] There are three types of sand making processes in the prior art: dry sand making, wet sand making, and semi-dry sand making. The dust pollution of dry sand making is serious, and only closed production can avoid the problem of dust pollution. The indicators of the finished sand produced by it are extremely unstable, because the production process cannot be well controlled, and excessive phenomena often occur; in addition, wet The French sand making process requires that the moisture content of the finished sand should be below 6%, which is not easy to control, and requires a large warehouse capacity for dehydration and drying of the artificial sand. The waste water discharge during the production process is large, and the loss of ston...
