Joint grinding is a vertical Ore Milling Equipment and ball Ore Milling Equipment in series with the new grinding process, vertical Ore Milling Equipment first clinker and mixed material pre-grinding, clinker after pre-grinding, grinding set within the inclined sieve device, escape Of the smaller material through the screening, screening of the fine powder into the ball Ore Milling Equipment; material after crushing and shearing smash, the particle size becomes very small, and there are many cracks, of which 30% less than 80um, the mixture Into the ball Ore Milling Equipment, for the ball Ore Milling Equipment to create a good grinding conditions; the top of the vertical Ore Milling Equipment for the design of the wind into the separator, through the powerful ventilation to reduce the disc material on the disc powder, powder after the qualified material into the finished product Library, the coarser material into the Ore Milling Equipment to continue grinding, grinding materials into the finished product after two grinding mill.
The traditional grinding parameters are developed under the traditional technical conditions. The production capacity provided by the equipment manufacturers are all determined according to the Ore Milling Equipment's rated output or calculated by the Ore Milling Equipment's production experience formula. The vertical Ore Milling Equipment and the ball Ore Milling Equipment pre-grinding must be based on the original equipment parameters for process matching calculations, but also the system of special process parameters taken into account in recent years, our hospital commitment to vertical Ore Milling Equipment and ball Ore Milling Equipment pre-grinding design Services, the project size is an annual output of 500,000 t of P032.5 cement grinding production line.
After commissioning, rectification and calibration of the project, the current output can be steadily stabilized at 71 t / h and the power consumption of the Ore Milling Equipment system is 29 kW / t. Vertical Ore Milling Equipment through the sieve to effectively control the material back to the material within the particle size of 1 ~ 6 mm (into the Ore Milling Equipment), increase the filling rate and increase the proportion and density of the material through the vertical Ore Milling Equipment top powerful ventilation to solve the phenomenon of over grinding, stable material Bed, increase the pressure capacity, improve the grinding efficiency; through the O-Sepa500 powder sorting machine, 10% of qualified products directly into the reservoir, 15% of less than 1 mm of coarse material into the Ore Milling Equipment.
After the material is pre-ground, the particles are crushed and sheared, the particle size becomes very small, and there are many cracks, of which 30% is less than 80um. After the mixture enters the ball Ore Milling Equipment, it makes a good grinding for the ball Ore Milling Equipment Conditions, coarse powder grading machine can be based on the size of the feed Ore Milling Equipment particle size grading, the smallest particle size can be less than 1mm. After the grinding particle size is reduced, the ball in the ball Ore Milling Equipment changes from large to small, and the small steel ball will reduce the waste of excess energy caused by the material crushing. In general, large ball than the high energy consumption, the ball than the low energy consumption; particle gradation, roundness of the scientific nature of the maximization of efficiency as the goal.
Vertical Ore Milling Equipment and ball Ore Milling Equipment pre-grinding technology focused on the combination of the advantages of pre-grinding and grinding, through the vertical Ore Milling Equipment, ball Ore Milling Equipment selection, vertical Ore Milling Equipment inside and outside the screening, grinding mill sieve combination of structural features, and Other grinding process comparison, small investment, low power consumption, a wide range of particle size distribution of cement, high strength cement. Improve the Taiwanese products, reduce product costs, economic efficiency is very significant. We put forward new ideas for research and development, popularization and application of new technologies, new techniques and new equipment, and taking the characteristics of a new type of industrialization road to improve resource utilization.
