MTW trapezium grinder mill application

MTW european trapezium grinder mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. The grinder mill machine can produce powder from non-flammable and non-explosive mineral materials, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc.

MTW trapezium grinder mill features

1. The bevel gear transmits in a whole, which makes the Grinding Mill Machine's structure more compact, installation and commission more convenient.
2. The internal oil pump of the grinder mill machine can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station.
3. Former straight wind tunnel in the traditional grinding mill machine is replaced by curved one.
4. Sheet of the shovel is easy for change, and cyclone collector in isolated type.
5. Porthole adopts smooth wind spiral, which also gives the grinding mill machine a very beautiful appearance.

MTW trapezium grinder mill working principle

MTW trapezium grinder mill workThe bevel gear transmits in a whole and drives the main shaft, who is connected with the roller hanger in the top. There are grinding rollers installed in the hangers and forming a swing support. The rollers rotate not just around the main shaft, but also around the grinding ring, besides, rollers can rotate to itself as well because of friction. Shovels are installed at the bottom end of hanger.

when shovels rotate together with rollers, materials will be fed into space between rollers and ring to form a material layer, which will be grinded due to centrifugal force. The classifier drives the blades in the rotary table through the speed motor to classify the powder.

MTW european trapezium grinder mill is mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. This grinder mill can produce powder from various non-flammable and non-explosive mineral materials with Moh’s hardness below 9.3 and humidity below 6%, such as quartz, feldspar, calcite, talcum, barite, fluoride, Xircom, cinder, white lime, cement clinker, activated carbon, dolomite, granite, soft coal, coking coal, lignite, magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, kyanite, fluorspar, bentonite, medicinal stone liparite, diabase, pyrophyllite, shale red stone, emeraldite, basalt, gypsum, graphite, carborundun, heat insulating material, etc.

MTW trapezium grinder mill operation and maintenance

In the operation period, grinder mill machine shall be strict compliance with operating procedures. To achieve constant attention to the grinding mill machine running sound is normal or not, check the lubrication of bearings and bearing temperature is normal, regular checks of the motor temperature and current, check the functioning of the transmission equipment. After the grinding mill outage, check the main bearings, hollow shaft, cylinder, reducer connections and other important components, and wear problems are discovered timely processing.

Forbidden piece of metal into the grinder mill machine, otherwise it will damage grinding roller and grinding ring, and even center hanger and so on. Feeding should be uniform, non-erratic. feeding too much will be blocked duct, lower output, easy to burn out motor, feeding too little is not good also. Feed size: hard material in the diameters less than 15 mm, preferably, soft material diameter of 20 mm, large pieces of material is strictly prohibited to join the machine.air volume control: in the fan on the intake manifold air flow control valve, generally open to maximum position, according to fineness, yield requirements appropriate adjustments. Is located in the exhaust pipe on the exhaust exit control valve, transferred to feed the mouth can be no dust emitted. Air volume is small, thin high. It should be noted, wind is too small, the host within a duct beneath the easy precipitation of materials, please be adjusted appropriately.
