What equipment is used for grinding in a calcium carbide chemical plant? Antworten

Calcium carbonate is a major component of limestone, which is the main raw material for the production of glass. Lime and limestone are used extensively as building materials and are important raw materials for many industries. Calcium carbonate can be directly processed into stone and fired into quicklime. Lime has quicklime and slaked lime. The main component of quicklime is CaO, which is generally in the form of a block, pure white, and pale gray or yellowish when it contains impurities. Quicklime absorbs moisture or adds water to become hydrated lime. Slaked lime is also called slaked lime. Its main component is Ca(OH)2. The slaked lime is formulated into a lime slurry, a lime paste, a lime mortar, etc., and is used as a coating material and a tile adhesive. The cement is prepared by mixing limestone and clay and calcining at a high temperature.
Limestone is a relatively common ore material in the market and a non-metallic mineral that is widely used. The market's limestone powder can be mainly divided into single fly powder, double fly powder, three fly powder and four fly powder, etc., which are widely used in construction, coatings, fillers and chemical and chemical fields. The chemical plant for producing calcium carbonate is mainly for the grinding and processing of limestone. If the size of the raw limestone is large, it needs to be crushed and pulverized first. The production line equipment that will be deployed in the limestone powder factory is TL jaw crusher + vsi sand making machine + TL vertical roller mill, of which TL vertical mill is the preferred equipment for large-volume industrial milling. The grinding equipment produced by SBM heavy machine has CM coarse grinding (0-80 mesh), TL vertical mill grinding machine (80-425 mesh, ultra-fine vertical mill (600-1250 mesh) and TL medium speed stand Grinding mill (800-3250 mesh) can meet the different needs of the market.
TL vertical mill grinding machine working principle: TL vertical mill is mainly composed of electric motor, reducer, grinding roller device, grinding disc device, pressing device, classifier, body, oil station, host PLC electronic control system and other parts. The main motor drives the grinding disc to rotate through the reducer, and the wind enters the vertical mill body from the air inlet. The material falls through the feeding port of the screw feeder in the center of the grinding disc. Under the action of centrifugal force, the material moves evenly from the center to the edge of the grinding disc. When the grinding roller area on the grinding disc is crushed by the grinding roller, the bulk material is directly crushed, and the fine material is pressed to form a material bed for intergranular pulverization. The pulverized material continues to move toward the edge of the disc until it is carried away by the strong airflow at the wind ring, and the larger particulate material is again dropped onto the grinding disc to continue pulverization. When the material in the airflow passes through the upper separator, the rotor Under the action of the blade, the coarse particles are returned to the grinding disc for grinding. The qualified fine powder is ground together with the airflow and collected by the system's dust collector. The collected powder is the product ground by the vertical mill. When the iron block and other impurities mixed into the material move to the edge of the grinding disc, they cannot be blown by the wind due to their own weight, and fall to the lower chamber of the mill. The scraper plate installed at the bottom of the grinding disc is scraped into the slag discharge port and discharged outside the machine. . By adjusting the rotational speed of the rotor of the multi-head classifier, qualified products of different fineness can be obtained.
