Vertical Roller Mill for Metallurgy Powder

LM Vertical Roller Mill for Metallurgy Powder

Introduction:

Steel forging and hot rolling processing, due to the reaction of iron and steel in the air and oxygen, often form iron oxide, these material accumulate and will waste resources. If we can use the resource reasonably , can reduce the production cost, and can play a role in energy conservation and environmental protection. At present tin oxide can provide to chemical plant can be used for producing red iron oxide, yellow iron oxide, ferric chloride, ferrous sulfate, also can produce ferrosilicon alloy, sintering raw material and producing sponge iron, high quality scrap. At the same time, it can produce iron powder by rough reduction method or refined reduction method.

LM series vertical mill can crush or grind the broken iron oxide which less than 30mm, processing into 50-325 mesh fine powder, then the fine powder used in the metallurgy or other purposes. The finished grain production of LM type vertical mill, with good shape, high bulk density, fully comply with new type material’s requirements.Our company produces the SRM series vertical milling machine has been successfully applied in
powder metallurgy industry, complete system stable operation, refined grain, high grinding efficiency. Bring economic value to customer, at the same time, it has also become a kind of new environmental protection equipment, saving resources.

Powder metallurgy is the process technology of making metal powder or use metal powder (or metal powder and nonmetal powder) as raw material, through forming and sintering, to make metal material, composite materials and various types of products . Powder metallurgy method is similar to the production of ceramic, are belong to the powder sintering technology. Therefore, a series of powder metallurgy new technology can also be used for the preparation of ceramic materials. As the advantages of powder metallurgy technology, it has become the key to solve the problem of new material, which plays an important role in the development of new materials.

Powder metallurgy related enterprises are mainly used in automobile industry, equipment manufacturing, metal industry, aerospace, military industry, instrument and meter, hardware tools, electronic appliances and other fields. Products include bearings, gears, carbide cutting tools, dies, friction products, etc. In military enterprises, heavy weaponry such as armor piercing projectiles, torpedo, etc, and so on. Powder metallurgy auto parts has become the largest market in China in recent years, about 50% of the auto parts for powder metallurgy parts.

Vertical Roller Mill Excellent Features:

• High efficiency: using rollers grind materials on the grinding disc directly consuming less energy. Compared with ball mill, it saves energy consumption by 30%~40%.As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
• Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is of high quality, so life lime is long and wear is less
• Stable Yield and High Quality.As materials stay in the mill for a short time, it is easy to detect and control the product’s particle size and chemical composition, which reduces repeated milling and stabilizes product quality. Moreover, roller shell and lining board don’t contact directly, so few iron are invelved into the product and these iron can be easily removed. Thus, to grind white or transparent materials, vertical mill produce product with high whiteness and purity. It is equipped with one limiting device, which prevents the roller from contacting with the liner directly, to avoid the destructive impact and severe vibration

Vertical Roller Mill Working Principle:

Full set of vertical mill consists of: main unit, bucket elevator, adjustable hopper, sealed constant feeder, air heating furnace, dust remover, blower and silencer.

The motor drives the grinding table to rotate by reducer, and the hot air goes into the inner part of machine at the same time. The materials fall down to the center of grinding table from feed opening. Driven by the centrifugal force, materials move evenly to the edge of the grinding table, and they are grinded by the rollers when going through the rollers’ track. Bulk materials are crushed, while fine materials form material bed after being squeezed and experience intergranular crushing. Grinded materials move on to edge of the grinding table until being taken away by strong airflow at the wind ring, in which larger materials fall to the grinding table by gravity and reground. The others enter the separator being graded. Under the influence of separator blades, materials that do not meet fineness requirements return to the grinding table to be grinded, while the standard ones go into dust collector through the pipes and are discharged as finished products from the discharge device. Irons and other impurities, which cannot be lifted by the wind for weight, move together with materials to the edge of grinding table and fall to the lower cavity, and then they are scraped i1 Setnto the slag discharge opening by stripper plate which is fixed at the bottom of the grinding plate and discharged out of the machine.
