Fly ash is China's current industrial waste larger displacement of one of the fly ash, with the development and utilization of space is more and more broad, the level of grinding mill corresponding technical requirements are also getting higher and higher, the market of Raymond mill, ball mill is a traditional can not meet the needs of processing capacity and fineness in industrial production, ultrafine vertical roller mill model become the mainstream equipment milling machine used in performance will use latest technology and convenient and efficient. By use of a vertical mill for grinding processing of the application in cement,mortar mixing, packing, brick is the most potential utilization way.
Vertical mill is the realization of mass of material grinding processing device using the roller system of large scale, automation advantages compared with ordinary milling machine is large and the operation of equipment. Usually vertical mill output can reach 100-500 tons /even higher. Vertical mill grinding roller is controlled by hydraulic system of specialized,flexible and convenient operation, easy maintenance. The current domestic market, vertical mill in various grinding production process to the comprehensive performance of the high energy saving has been be way ahead in the grinding powder machine.
Vertical powder processing mill ash use:
Fly ash is mainly used in building materials, construction, road construction, back filling,agricultural and resource recycling and other aspects.
(1) fly ash concrete, fly ash concrete used widely, in Civil Engineering (including water conservancy project), construction and precast concrete products and parts are widely used.
(2) fly ash used in road construction and filling: fly ash as filling material used in engineering, is an important way of large amount, the direct use of the.
(3) fly ash products: ash products can be divided into non firing and firing type, non fired fly ash building. With the use of fly ash pozzolanic activity, cooperate with calcareous material, reaction with in a certain temperature and humidity conditions, produce hydration products and obtain a certain strength and other performance.
(4) application of fly ash in agriculture: fly ash particles were mainly composed of coarse particles (0.25 ~ 0.01mm) and fine particles (0.005 ~ 0.001mm). The structure of fly ash particles determines compared with soil moisture, ash water more easily utilized by plants.The above characteristics in agriculture has been fully affirmed.
(5) further utilization of fly ash: fly ash is a mixture of hollow vitreous body component,wherein the glass bead system silica alumina carbon in the vitreous, porous carbon particle and clastic carbon particles appeared in the iron rich glass beads.
