Energy-saving environment-friendly type industrial residue closed-circuit high-yield super-fine mill controlling technique and equipment thereof

Abstract

This invention provides energy-saving environmental friend closed-loop high yield high fineness grinding control technique and its device for industrial solid waste. The technique integrates baking and grinding, uses detection on line, adjust and control the parameters automatically. Thereby, the invention cuts process, realizes automatic control and adjustment, increases application value of the said waste and its added value. The equipments comprise added air-swept baking grinder, online laser particle detector, automatic controller, and high-effect powder selector and dust catcher, which decreases occupation of land, investment and energy consumption, increases efficiency and quality, and has well economic and social benefit.

Description

Technical field [0001] The invention relates to an industrial waste residue grinding process and equipment, in particular to an energy-saving and environment-friendly closed-circuit high-yield and high-fine grinding control process and equipment for industrial waste residue. Background technique [0002] Industrial wastes such as slag, steel slag, fly ash, and coal gangue are mostly compressed or disinfected and then landfilled or simply used as admixtures. Later, it was found that almost all industrial wastes can find application value in industries such as building materials. Especially after processing and grinding, it can be used as admixture in building mixture materials, concrete and its products. The current industrial waste slag grinding process and equipment are usually as follows: the industrial waste slag is deironed by the iron remover and crushed by the crusher, and then the material is lifted to the silo by the hoist, and then sent to the rotary or vertical dr...

AI Technical Summary

Problems solved by technology

[0003] Since the current process is an open circuit process, the process is long, the process control and adjustment are inconvenient, the output is low, the grinding fineness cannot be guaranteed, and the equipment occupies a large area, requires an independent drying system, high investment, low degree of automation, High energy consumption, poor work efficiency, only suitable for a single variety, and the economic benefits are not very significant
