This new industrial mill takes the most advanced patent technology from European, and the supply the customers with outstanding performance at low costs.

Introduction

MTW series grinding mills obtain international advanced technology as well as many proprietary intellectual property rights.The electric system adopts centralization of control. Feed size is small and light that save the energy. The standard configuration of MTW Grinding Mill consists of main unit, powder classifier, blower, elevator, feeder, hopper, cyclone collector, dust catcher, blower, motor, pipe, electric control box and so on. Based on the years’reseach experience and the suggestion of our customer, the MTW series is the latest grinder .The MTW grinding mill adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and other latest technologys.And now it has been used In the field of Metallurgy, building materials, chemical, mining and can be applied to crush the materials like Quartz, feldspar, calcite, talcum, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper, phosphorus ore, zircon sand, slag, water, slag, cement, etc. MTW Grinding Mill widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing. According to the fine grinding of materials and discharging materials fineness.

Structure Features

1)Bevel gear integral 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.The traditional mill needs decelerator and ratcheting to drive the main shaft that increases the installing difficulty and is easy to bring noise and reduce the efficiency.

2) 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. The traditional mills’ lubrication adopts grease lubrication which increases the resistance of lubrication, creates high inherent temperature and shortens the service life of bearing.

3) Arc whirl tube: MTW series mills adopt arc whirl tube to reduce the resistance and avoid the air-stop and so on. The traditional mills adopt board-type whirl tube that increases the resistance, reduces the performance, and stops the air flow and so on.

4) Curved surface shovel with changeable edge: The traditional mills adopt quick wear edge and edge is combined with shovel. If the edge is worn, all of the shovel should be changed, which increases the cost and the off time. The edge of MTW series mill adopts wearable alloy materials which improve the service life. The Changeable edge is easy to change, which saves time and cost. The traditional flat shovel make the materials accumulate in one level, which reduces the ring and roller’ service life. The curved surface shovel makes a vertical material liner, which increases the working face and capacity.

5) Insolating type cyclone collector: Adoption of the insolating structure between the inner core and mixed air flow improves the classifying efficiency and precision. While the traditional one do not have the isolating structure.

Main Structure

MTW Grinding Mill's main structure are including the main machine body, classifier, wind machine, jaw crusher, sustpan lifter, electric vibrating feeder, the storehouse, the bag dust catcher, whirl wind classifier, the electric cabinet and also the motors.MTW series mills features floor standing model, small occupation area, stable transnitting, advance and reasonable selection, high automatic degree .The important parts adopt high-quality steel, which optimizes the appearance and enhance the durability effects.The electric system adopts centrallized control, and features high degree of automation .and the size of the vibrating feeder is small and light, which is controlable and energy-saving .
