Fly Ash Grinding by VRM:
Production, fly ash is an industrial waste residue. Today, there are millions of tons of industrial waste residue in emissions, this phenomenon is particularly serious in developing countries. A large number of unprocessed fly ash will generate dust and pollute the atmosphere; discharged into the water system, the fly ash can be caused by blocked rivers and toxic chemicals contained in it, will be harmful to humans and life forms. Therefore, conserve resources, reduce pollution, processing and utilization of fly ash has become a hotspot of human called pay close attention to a new field.
Today, large-scale ultrafine mill has been able to achieve a one-time Ultrafine Materials Processing. The uniform size, being processed factory fine fly ash material having improved surface activity. Added directly to the concrete, they will save a lot of cement raw materials, they will also improve the operability of the concrete mixing materials, improve plasticity and stability of reinforced concrete. Even in cement production enterprises, people fly ash mixed, in accordance with the ratio of 8%, to different cement clinker cement products. In the current situation, had diversified development trend of the world cement grinding technology, grinding equipment development to large-scale, low-power-efficient direction. With the continuous progress of science and technology and innovation, cement grinding mechanism is no longer limited to the traditional inefficient ball, forging grinding way, but rather gradually to the development of energy-efficient direction.
fly ash grinding by VRM Vs Ball mill
Ball mill:
The mill is widely used in the fields of metallurgy, building materials, chemical, mining minerals such as grinding materials processing. According to the grinding fineness of materials and discharging materials fineness, milling machines can be divided into Raymond Mill, vertical pendulum Mill, high pressure hanging roller mill, high pressure Powder Mill, Straight Centrifugal Grinder machine, overpressure trapezium mill, ring medium speed mill mill type. Ball mill is one of them.
The ball mill is the material to be broken, and then to smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramics production industry, on a variety of ores and other grind-able materials dry or wet grinding. Suitable for ball mill grinding various ores and other materials, are widely used in mineral processing, building materials and stone industries, and can be divided into dry and wet two grinding. According to the different ways of discharge can be divided into lattice type and overflow type two.
The ball mill is a horizontal cylinder, expected out of the hollow shaft and the grinding head parts, barrel length cylinder, barrel equipped with a grinding body, cylinder steel plate manufacturing, fixed steel liner and cylinder grinding body generally steel balls, to press different diameter and a certain percentage of loaded barrel, grinding body can also be used to steel segment.
Be selected according to the granularity of the abrasive material, and material from the ball mill feed end of the hollow shaft into the cylinder body, ball mill rotating cylinder grinding body due to inertia and centrifugal force, the friction force, it posts near the cylinder liner cylinder away, was taken to a certain height when being thrown, due to its own gravity, the whereabouts of the grinding body like a projectile to the cylinder body materials crushed. Material from the feed device into the compound empty shaft spiral evenly into the mill first warehouse, the warehouse there are ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, the thump and grind the material. The material in the first warehouse, coarse grinding by monolayer partition panel into the second position, the warehouse lined with flat lining with steel balls, the material further grinding. Powder discharged through the discharge grate plate to complete the grinding operation. Cylinder in the process of turning, grinding body slipping phenomenon, to the material to the grinding action in the slipping process, in order to effectively use the abrasive material granularity teach general 20 mesh pulverized when the mill body cylinder with compartment plate separated Sec dual positions become material into the first positions when they were crushed by the steel ball, the material into the second position when the steel end materials grinding finely ground material from the discharge end of the hollow qualified shaft discharge small particles of feed material pulverized when, as sand the 2nd slag, coarse fly ash, mill shell may from time to set up partitions, a single silo mill grinding volume of the steel segment .
Fly Ash Grinding by VRM Vs Ball Mill:
When processing fly ash, grinding, we can use the VRM, ball mill. They are feasible to run the program, and use good practice validation. Specifically, how to deal with the need for production requirements and processing power to carry out the analysis and design, so it should please the manufacturers of professional or technical personnel to carry out the investigation calculated to give practical solutions.
