Technology for analog-digital control of fineness of smelting waste dregs

Abstract

The invention discloses a technology for analog-digital control of the fineness of smelting waste dregs. According to the technology, three types of different screen holes in a vibrating screen are used for screening semi-finished products, a fineness controller is used for controlling the amount of the semi-finished products of which the particle sizes are smaller than 5mm after screening, part of the semi-finished products of which the particle sizes are smaller than 5mm or greater than 5mm are transported into an adjustment storage bin, and one part of the semi-finished products entering the adjustment storage bin are adjusted into a secondary adjustment conveying belt and enter the vibrating screen again for screening; the other part of the semi-finished products enter a returned material transfer conveying belt and are transported into a crushing machine for crushing, the semi-finished products crushed by the crushing machine are conveyed into a first conveying belt through a mixed material conveying belt, and the steps are circulated. Compared with the prior art, through the circulation of screening, crushing and screening, the particle sizes of the smelting waste dregs can be controlled, and through mixed material screening, adjusting and crushing of the semi-finished products of which the particle sizes are smaller than 5mm or greater than 5mm, the product quality can be effectively improved, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to a production process of building materials, in particular to a fineness modulus control technology of smelting waste slag sand. Background technique [0002] Concrete is generally made of cement as cementitious material, sand and stone as aggregate, mixed with water (with or without admixtures and admixtures) in a certain proportion, and obtained by stirring, molding and curing. It has a wide range of applications. It is not only used in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. With the continuous development of economy and science and technology, my country's urban construction is becoming increasingly hot, which requires a large amount of concrete, and most of the aggregates used in the preparation period of existing concrete are mostly natural sand and stone, but as The sand and stone resources of natural ...

Problems solved by technology

However, industrial waste must be further processed before it can be used again. In the traditional process of processing smelting waste, it is basically crushed by a crusher first, and then screened by a screening machine. This traditional In this way, the particle size of the finished product cannot meet the requirements of the product, and the high energy consumption is likely to cause secondary pollution
