The development of the solid waste residue industry, the special dry process vertical mill for equipment in the slag powder industry is a new type of grinding mill that increases production and reduces consumption. It has high grinding efficiency, fast powder selection efficiency, and fine classification accuracy. It is favored by the industry and is the promotion of solid waste residue The new vertical mill developed by the industry.
A new generation of vertical mills, ultra-fine mills and other equipment not only have high grinding efficiency, but also have the advantages of green environmental protection, low noise, increased production and efficiency, and low civil construction costs. Cement raw meal, clinker, manganese ore and many more markets.
The slag micropowder does not need to go through the crushing process in the production, because the size of the raw material is small, but because the slag is a by-product of the blast furnace ironmaking process, the humidity is high, so it needs to go through a drying operation, and the dried raw materials are added to the machine through conveying equipment. Grinding is carried out in the pulverizer, and the finished product is transported to the finished product warehouse for storage. Therefore, the production process of slag micropowder mainly includes the following parts: feeding, conveying, drying, grinding, collecting powder, warehousing, etc.
The vertical pulverizer has the advantages of high grinding efficiency, low power consumption, large feeding particle size, easy adjustment of product fineness, simple equipment process, small footprint, low noise, small dust, easy use and maintenance, and low operating costs. Advantages such as less consumption of wear-resistant materials. Can be widely used in electric power, metallurgy, cement, chemical industry, non-metallic minerals and other industries, mainly used for cement raw meal, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, aluminum Bauxite and other materials are ground for processing.
The vertical mill system is composed of main engine, feeder, classifier, blower, piping device, storage hopper, electric control system, collection system, etc. The pressurizing device is designed and manufactured in a standardized module type. With the increase of the vertical mill production capacity, the number of grinding rollers of the vertical mill is correspondingly increased. The motor-driven reducer can be used to drive the grinding disc to rotate, and the material moves around the grinding disc under the action of centrifugal force. Entering between the grinding roller and the grinding disc, under the pressure of the grinding roller, the material is crushed by extrusion, grinding and shearing force. The coarse ones still fall into the main machine for regrinding, and those with fineness that meet the specifications flow into the pulse dust collector with the wind. After collection, they are discharged through the powder outlet pipe to be the finished product. The purified air flows through the pipeline on the pulse collector and flows into the blower before being discharged into the air blower. atmosphere.
Whether the equipment used in the production of slag micropowder, whether it is a feeder or a pulverizer, whether the model selection is reasonable, is related to the revenue of slag micropowder production. Generally, when configuring the slag micropowder preparation process, the main reference is the size of the production capacity, the quality of the finished product and other factors, and the appropriate production line is selected to ensure the smooth production.
