Since the early 1980s MEG has been designing and manufacturing high-performance grinding mills under the MEG brand.

Introduction

MEG grinding mills are reliable, high-performance, low-maintenance demolition tools that give a low cost per ton of material processed.

MTM trapezium grinding mill are designed to crush and grind stones and non-metallic products such as kaolin, gypsum into powder. It adopts the ladder-shapper roller and ring improving crushing eddiciency and produce a typical product size of 1.6 mm to 0.038 mm when operating in open circuit and in closed circuit with a screen or other sizing device. Moreover, The pressure springs have balancing and pressurized function. The elastic connections reduce vibration, keep balance, and avoide resonance.

MEG is ready to help your grinding plant with best grinding mills and other mining equipments.

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 .
