Vertical grinding mill is a kind of ideal large grinding equipment, widely used in cement, electric power, metallurgy, chemical industry, non-metallic mineral industries. It sets the crushing, drying, grinding, grading conveying in one, the production efficiency is high, the powdery material can be massive, granular and powder grinding materials required. Vertical grinding mill in metal mine, non-metallic minerals, stone and other materials powder processing process, the main technology embodied in the low investment and operating cost, product quality high, stable operation and maintenance more convenient, energy saving and environmental protection and no pollution in four aspects.
The three kind of method is effective to improve the vertical grinding machine grinding production capacity?
Basic Info
Lime stone vertical grinding mill
Lime stone vertical grinding mill fusion of elaborate design, the world state of technology experts and engineers to test and improve the development, highlight structure flexible trapezoidal face and connection of the device, the grinding roller supercharger and many other Choi won the industry peers and users agree.Vertical grinding mill by the host machine, blower, analysis, product cyclone separator, pipeline equipment, motor constitute. In the meantime the host is composed of a machine frame, a wind inlet volute, blade, roll grinding, grinding ring, a cover casing and a motor. Assist equipment jaw crusher, hoist, electromagnetic vibration feeder, electric control cabinet, the user can flexibly select on the basis of field conditions.
The grinding process should be the mineral grains once grinding to a monomer separation should be agile mill discharge from an independent and impartial. So on the one hand, can prevent excessive wear, on the other hand, can make the grinding media (such as steel) full effect in coarse mineral particles, so that the energy can maximum limit to work. But the existing mills in to material particle size classification is very difficult, the classifier or fine screen will be grinding goods qualified grade separation, coarse grain back vertical mill in regrinding (also called sand return). Visible in the closed-circuit grinding, vertical mill to mine for new ore and return sand, so the vertical grinding mill through the material, the material through vertical grinding speed is accelerated. By the grinding time is short. In closed-circuit grinding, to force the unqualified coarse repeat after vertical mill until the grinding to the qualified so far. Secondly, the closed-circuit grinding, due to the large amount of sand into the vertical mill, feed coarse grain content add. According to the principle of grinding kinetics. Then the energy maximum limit to make the useful work, so the grinding speed, vertical mill productivity progress. In addition, because the existence of proper return sand, can eliminate the vertical mill for ore new waver while the impact of commodity grain size.
