MTW Series Trapezium Mill

MTW Series trapezium mill is the latest grinding mill, which is developed by our company’s experts based on 10 years’ R&D on grinding machine. It owns many independent patents property, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. All of these make it leading the trend of the milling industry in the world.

MTW Series -Tapezium-mill

Working principle

Closed system: the bulk materials after crushing to the desired size, by the elevator to the storage hopper, the vibrating feeder will quantitative material is continuously fed into the host grinding, powder grinding with centrifugal fan the air to rise, enter a grading powder selecting machine, powder with fineness standard with gas flowing through the pipes enter into the cyclone powder collector were isolated and collected, the discharge valve discharge is finished powder. Air by a cyclone powder collector top return air duct into the centrifugal fan, the air circulation system, in the positive and negative pressure state circulation flow. An exhaust pipe in centrifugal induced draft fan outlet, the excess gas into the dust remover to filter, and then discharged node clean gas, to achieve environmental protection production.

Open system: the bulk materials after crushing to the desired size, by lifting to the storage silo, the vibrating feeder will quantitative material continuous into the host internal grinding. The powder milled by a draught fan wind belt to the separator are graded, powder standard through the powder selecting machine into the pulse dust remover to collect, the screw conveyor discharge is finished, and the pulse dust filter after the clean air is discharged with fan. Open system operating in the state of negative pressure, no dust leakage.
