Raymond Mill has been widely used in the processing of non-metallic minerals since it was introduced into China for more than 20 years. However, with the extensive development of non-metallic minerals in the field of ultra-fine powder applications, downstream companies have increasingly higher requirements for non-metallic mineral products, especially with higher requirements for product fineness, which has made traditional Raymond mills Looks weak. To this end, Dalier Heavy Industry Technology Department conducted in-depth analysis and research on traditional mills, and solved many fatal defects such as frequent maintenance, high maintenance costs, and substandard grinding of traditional Raymond mills. The new ultra-fine Raymond mill with crushing, grinding and super-fineness. Because of its high efficiency, low energy consumption, ultra-fine, small footprint, low capital investment and environmental pollution, etc., it is widely used in the grinding of mineral materials in metallurgical, building materials, chemical, mining and other fields, suitable for Processing of various non-flammable and explosive minerals with a Mohs hardness level below seven and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite , Maifanite, bauxite, iron oxide red, iron ore, etc.

Sodium bicarbonate (baking soda, NaHCO3) can be used as an adsorbent for flue gas desulfurization. It removes acidic pollutants from flue gas through chemical adsorption, and at the same time, it can remove some inorganic and organic trace substances through physical adsorption. This process sprays sodium bicarbonate fine powder (d90: 20um) directly into high-temperature flue gas at 140-250 ° C. Decomposition of sodium bicarbonate at high temperature produces sodium carbonate Na2CO3, H2O and CO2.

The motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, it moves to the edge of the grinding disc and is crushed by the grinding roller. The crushed material overflows from the edge of the grinding disc and is at the same time from the nozzle ring ( Air ring) The high-speed upward hot air flow is brought into the high-efficiency powder separator integrated with the vertical mill. After the coarse powder is sorted by the separator, it is returned to the grinding disc and re-milled. Collected in the dust device, it is the product. Coarse particles and metal parts that have not been carried by the hot air flow fall from the wind ring, are scraped out by the scraper, and then fed into the mill by the outer-circulating bucket elevator to be ground again.

CR series ultra-micro impact crusher is an advanced crushing technology developed by our company based on a large number of experiments on the basis of many years of production of crushers, the introduction of advanced crushing technology from the United States, combined with domestic advanced milling experience, and engineering experts Crushing equipment. It uses impact, collision, and shear as its crushing mechanism, with high crushing efficiency and narrow classification particle size range. The crushing and grading of materials are completed in the same body and each runs independently. It has the characteristics of compact structure, small footprint, adjustable product fineness, and convenient maintenance

working principle: Air classifier is composed of feed inlet, adjustable air inlet, material dispersion area, classification area, and air outlet. A material disperser is set in the material dispersion area to fully disperse the materials entering the classifier to form a stable classification flow field to facilitate classification. The classification area is composed of a working chamber, a turbine-type classification wheel, and an electric motor. Wear-resistant treatment, the speed of the motor is controlled by the inverter to achieve the purpose of stepless speed regulation.
