The main component of limestone is calcium carbonate, which is a sedimentary rock made of calcite or aragonite minerals. Mined limestone (calcite, limestone) is directly ground into powder to make ground calcium carbonate (GCC).
The main crushing equipment adopts advanced hydraulic control technology with stable and reliable performance. The limestone crushing plant adopts two-stage crushing and sand making process, and modular installation, which not only saves the land area and installation period, but also facilitates the inspection and maintenance of the equipment.
The limestone crushing system consists of a GBZ2000×10000 heavy-duty plate apron feeder and a PCF2018 single-stage hammer crusher. The designed production capacity is 500 tons per hour, but the actual production capacity is less than 400 tons per hour. After on-site observation, It was decided to transform the limestone crushing plant to increase the output to more than 460t/h.
Kaolin will produce a large amount of tailings waste after ore beneficiation and recovery. Due to less recycling of kaolin tailings, as the tailings continue to accumulate, they will occupy a large amount of land, pollute water quality, cause vegetation damage and soil erosion, and even cause mudslides, which will seriously affect the ecological environment. Therefore, comprehensive utilization of kaolin tailings and recycling them can effectively prevent waste of resources and damage to the environment.
The belt conveyor is mainly composed of a conveyor belt, an idler pulley, a belt tensioner and a driving device.
Dust treatment in the crushing workshop of the beneficiation plant is a systematic project, which requires specific dust conditions (temperature, humidity, particle size, acidity and alkalinity, cohesiveness, infiltration, etc.), pipeline layout, collection methods, and equipment at specific dust process points. Comprehensive consideration of all aspects such as operating cycle. We have summed up the dust management experience in the crushing workshops of hundreds of mines in quarries, copper mines, iron ore, lead-zinc mines, etc., and put forward the following problems that are prone to dust management in mine crushing workshops.
Belt conveyor is a reliable and low-cost conveying method for handling solid bulk materials. According to different application scenarios, belt conveyors have many types. For example, long-distance and large-capacity fixed belt conveyors, belt conveyors in open-pit mine stripping dumping systems, long-distance curved belt conveyors, tubular belt conveyors, stackers, stackers, and tire movement conveyors, crawler mobile conveyors, fabric spreaders, ship loader, ship unloader, intelligent car loader and other conveying equipment.
The bead mill is a modular mill specially used to grind fine particles to sub-micron size. The processing material of the bead mill includes three stages: wetting, grinding and dispersing.
Before the completion of this transportation line, many cement companies relied on short-distance transportation of about 12 million tons of cement clinker each year on local roads all year round. Because this transportation line is very important to the economic development of the Yangtze River Delta region, the transportation volume is very large, and the long-term use has caused the road to be seriously damaged, there are many hidden road safety hazards, and the dust and mud seriously damage the local environment.
The modified pulse baghouse dust collector can meet the new grinding process requirements of the closed-circuit grinding process system, and the discharge concentration at the outlet meets the national emission standards.
