As we all know, the exhaust gas from industrial production, the dust generated by construction sites and road traffic are important components of haze, so it is inevitable to accelerate the pace of energy conservation and environmental protection in the construction machinery industry. The so-called no break, no stand, smog is not only a direct crisis to alert the world, but also a potential opportunity to promote the environmental protection of machinery.
Exhaust gas from industrial production, fugitive dust from construction sites and road traffic are important components of haze. Desulfurization equipment, as a large-scale desulfurization machine, has made indelible contributions to social construction and solved a lot of waste gas pollution, among which the desulfurization mill is a very good equipment.
Desulfurization mills are also called pulverizers, which have many types, mainly including vertical mills, Raymond mills, ultra-fine mills, etc. The vertical mill is one of the main products of the desulfurization mill. Let's take the vertical mill as an example to tell the general information of the desulfurization mill:
Application scope: It is widely used in cement, electric power, metallurgy, chemical industry, non-metallic mining and other industries.
Processing materials: limestone, calcite, dolomite, barite, talc, calcium carbonate, gypsum, bentonite, etc.
1. High grinding efficiency and low operation cost.
The vertical mill uses the material layer grinding principle to grind materials, with low energy consumption. The power consumption of the grinding system is 20~30% lower than that of the ball mill, and with the increase of raw material moisture, the power saving effect is more significant. The grinding roll sleeve can be turned over for use, which is conducive to extending the service life and reducing the production cost.
2. Low construction and investment costs.
The vertical mill integrates fine crushing, drying, grinding, powder selection and transportation. It does not need additional drying, powder selection, lifting and other equipment. The dust bearing gas from the mill can be directly collected by the high-density bag filter or electric dust collector. The layout is compact and can be arranged in the open air. The building area is about 70% of the ball milling system, and the building space is about 50-60% of the ball milling system. Therefore, the process flow of vertical mill is simple, and the occupied area and space are small, which makes the construction cost low.
3. Easy and reliable operation, simple operation and maintenance.
It is equipped with rare lubrication station, and the grinding roller bearing adopts thin oil centralized circulating lubrication. The bearing works under low temperature and pure oil conditions, extending its service life and making the equipment operation system operate continuously and reliably. Equipped with automatic control device, remote control can be realized, and the operation is simple and easy. With the help of roll turning device, the grinding roll can be turned out of the mill, and the roll sleeve and lining plate can be replaced and overhauled in a short time.
4. The equipment has large drying capacity and extensive grinding materials.
The vertical mill uses hot air to transport materials. When grinding materials with large moisture, the inlet air temperature can be controlled to make the products reach the required final moisture. In vertical mill, materials with moisture content up to 15% can be dried, which can be widely used. Even the drying ball mill can only dry materials with moisture content of 3% - 4%.
5. The product quality is stable and the particles are evenly distributed.
The retention time of materials in the vertical mill is only 2-3 minutes, while it takes 15-20 minutes in the ball mill. Therefore, the chemical composition and fineness of vertical mill products can be quickly measured and corrected, and the quality is stable.
6. The equipment is environmentally friendly, with low noise, less dust and clean operating environment.
During the operation of the vertical mill, the grinding roller and the grinding disc do not contact directly, and there is no metal impact sound of steel balls colliding with each other in the ball mill and steel balls colliding with the lining plate, so the noise is low, 20~25 decibels lower than that of the ball mill. In addition, the vertical mill adopts a fully sealed system. The system operates under negative pressure, without raising dust, and the environment is clean.
