Cement is a common type of cement produced by cement manufacturers. Cement uses cement vertical mill production line for energy saving and environmental protection. The area of plant and milling machinery is smaller than that of traditional ball mills, and the noise decibel is low. The whole set of cement vertical roller mill production line adopts PLC central control system. Significant savings in labor costs. Cement, also known as Portland cement, is made of Portland cement clinker and grinded with appropriate amount of gypsum. The code is pn.Fn, which is made of Portland cement clinker and appropriate amount of gypsum. A hydraulic cementitious material called Portland cement, codenamed Pn.Fn. The participation amount in cement is 20%~40% by mass percentage, and its strength grade and strength requirements of each age are the same as slag Portland cement.
1. Performance of cement vertical mill:
The cement structure is relatively dense, the internal specific surface area is small, and the adsorption capacity for water is much smaller, and the water requirement for cement hydration is small, so the dry shrinkage of the cement is small and the crack resistance is good. In addition, similar to the cement generally mixed with active materials, the hydration heat is low, and the corrosion resistance is strong.
2. Environmentally-friendly configuration of cement vertical mill production line:
The environmentally-friendly configuration of cement vertical mill grinding production line consists of vertical mill main machine, reducer, fan, crusher, feeder, storage tank, air duct, pulse dust collector (fully conforming to current high environmental standards) and packaging machine. The pulse dust-removing equipment is equipped to meet the high environmental protection standard and is cost-effective.
3. The level interval that the cement vertical mill grinding production line can produce
Commonly used in the industry are Level 1, Level 2 and Level 3 standards. The cement vertical mill production line can produce a first-order fineness (45μm of the sieve machine mesh, ie 325 mesh), two grades and three grades. Suitable for cement formula, sintered porous brick production, pe sheet, brick jc239, aluminum and dry extraction float beads, etc. The first grade is mostly used for cement raw materials, and the second grade is widely used in reservoir dams, high-rise buildings, railways, highway bridges, culverts, highways, chemical industry, oil fields, etc. As a mixed soil additive, it can replace a part of cement and reduce the construction cost.
Comprehensive utilization of the industry within the micro-powder industry fineness criteria to define the interval, the first level is 325 mesh fineness of the pass rate is 88%, the secondary 325 mesh fine powder pass rate is 75%, the third-level is not worth the money. In addition, the cement vertical mill grinding powder line can be equipped with vertical mills for powder or other non-metallic mineral products. The fineness specifications are: 100 mesh, 200 mesh, 325 mesh. If the mill production line is equipped with an ultra-fine vertical mill, It can produce 400 mesh, 500 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 2000 mesh, 2500 mesh or even 3000 mesh or more ultrafine mineral powder.
Introduction to the working principle of cement vertical mill: ZJTL-K series cement vertical mill is compact, small in size and fully enclosed, mainly consisting of high-efficiency classifier, grinding roller device, grinding disc device, grinding roller hydraulic loading device, hydraulic lubrication system, reducer , motor, electrical and other components. The separator is an efficient and energy-saving powder sorting device. The combined conical grinding roller is a component used for crushing and crushing materials. The grinding disc is fixed on the output shaft of the reducer, which is the place where the grinding roller crushes the material. The hydraulic loading device is a component that provides the grinding pressure to the grinding roller, and provides sufficient pressure to the grinding roller to pulverize the material.
