MTW Series Continental Trapezoid Grinding mill

The MTW Series Continental Trapezoid Grinding mills are mainly applied to the powder processing of mineral products in the industries of mining,metallurgy,chemical,and contruction materials,etc. They can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below 9 and humidity below 6% ,such as quartz,feldspar,calcite,talcum,marble, ceramics ,iron mine,soft coal ,dolomite,active carbon,plum sandstone,basalt,etc. mtw series trapezium mill Technology Advantages
◆Main shaft transmission: MTW series mills adopt bevel gear integral transmission ,which will better compact the whole structure , simplify the installation as well as improve the efficiency.
◆ Inner lubrication system: MTW series mills adopt light-oil lubrication to achieve the lubrication between the main bearing and gear bearing, without oil pump or lubrication station.
◆ Arc whirl tube: MTW series mills adopt arc whirl tube to reduce the resistance and avoid the air-stop and so on.
◆ Curved surface shovel with changeable edge: The edge of MTW series mill adopts wearable alloy materials which improve the service life.
◆ Insolating type cyclone collector: Adoption of the insolating structure between the inner core and mixed air flow improves the classifying efficiency and precision.
◆ non-resistance inlet shell: the consumption. MTW series mill adopts the same curved surface which avoids the eddy effect.
Working Principle
◆Raw material which has been crushed to the size specified is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will transferred evenly and continuously into the grinding chamber for powder-processing. After this,the ground stuff is carried by the air from the blower into the classifer for regrinding.The set’s airflow system is closely sealed up and circulated under the condition of negative and positive pressure.
◆ The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products .
◆It plays an important role in ensuring the function of the grinder . As the high-speed revolving air current mixed with ground stuff is flown into the cyclone-collector ,the ground stuff is separated from the air-current .
