SBM Vertical Powder Mill to Process Slag in Cement Industry
Slag powder is short for Granular Blast Furnace Slag Powder. It is a kind of high quality concrete admixture. It is made of granulated blast furnace slag conforming to GB / T203 standard. After being dried and pulverized, the slag reaches the fineness and meets the requisite activity index body. Modern slag has become an important cement mixed material, but the wear of slag is poor, so choose the appropriate process is particularly important. Analyzed and compared the common grinding, the separate grinding, the mixed grinding and the united grinding process based on the roller press, respectively, it is considered that the pre-grinding of the slag by the roller press can improve the cement quality and save the energy. Meanwhile, The choice of grading equipment in the grinding system is also important. Slag powder used in cement is a lot of its performance can be prepared high strength, high performance concrete. Superfine slag concrete slag water retention, good plasticity, less bleeding, with good workability.
Now with the economic development, the cement grinding station industry began to shift to large cement grinding equipment, and now the cement grinding station is not a small cement factory, casually get a mill is a cement grinding station. Cement grinding, we must take it as a system, do not look as a separate piece of equipment. SBM recommends using ultrafine mill cement grinding machine, the output, low energy consumption, in full compliance with the requirements of large-scale grinding station construction.
SBM professional use to create a vertical mill, the material by the lock wind feeder from the feed inlet fell on the central mill, while hot air from the inlet into the mill. With the rotation of the grinding wheel, the material moves to the edge of the grinding wheel under the action of centrifugal force and is crushed and crushed by the grinding roller after passing through the annular groove on the grinding wheel. The crushed material is brought by the high-speed airflow in the wind ring at the edge of the grinding wheel Particles fall directly onto the disc re-grinding, air flow through the upper part of the material in the separator, the role of the rotating rotor, the coarse powder fell from the cone to the disc re-grinding, qualified powder with the air out of the mill, through the income Dust collection device, that is, products, materials containing moisture in contact with the hot air flow is dried, by adjusting the hot air temperature to meet the requirements of different humidity materials to achieve the required product moisture. By adjusting the separator, you can achieve the desired thickness of different products.
