Vertical mill to help fly ash change into green building materials

Face piles of fly ash industrial solid waste, the problem in front of mankind is how to effectively speed up the recycling of industrial solid waste, vertical grinding mill as an advanced milling tool, play pivotal role in the comprehensive utilization of fly ash, Guilin Hong Cheng manufactured fly ash vertical grinding mill is advanced milling equipment, with features of targeted, professional and other advantages, is the powerful weapon for fly ash in the field of green building materials.

First, the role of fly ash in green building materials

Extract alumina from high-alumina fly ash can reduce the environmental pollution of fly ash, also alleviate the shortage of bauxite resources in China. However, the problem of environmental pollution caused by waste residue in the process of extracting alumina is highlighted. Calcium and calcium slag is a high alumina coal combustion after the fly ash extraction of alumina, the calcium carbonate is the main component of solid waste, it is the typical abandoned things of high aluminum coal-electricity-ash-aluminum recycling economy chain. It is understood that, in addition to high alumina coal can extract alumina, the production of secondary products generated by the reaction of calcium silicate also has a high economic value, which has been has been verified in the paper production line. Calcium silicate slag generated from fly ash extraction of alumina, can be used as raw materials for the production of cement, solid waste from the extraction of alumina produced in the process of waste residue can be fully utilized as long as the supporting construction of cement plants,

Second, the use value of vertical mill

Vertical mill has an important value in the large-scale production of non-metallic mineral, with the development and expansion of the market, vertical mill as energy-saving environmental milling equipment vigorously promote by the country, is effective for coal, industrial solid waste, tailings, fly ash and other areas to provide a full set of milling production line solutions. The equipment has the characteristics of drying, grinding, classifying and conveying. It can effectively solve the problem of low production, high energy consumption and high cost of maintenance. The performance of the equipment is the industry leading level, and it is the mainstream equipment for comprehensive utilization of fly ash.
