Product Introduction

The MTW series European trapezoidal grinding machine, which has international advanced technology and multiple independent patent technology property rights, is the latest grinding equipment. It is the latest type of grinding machine designed by our company's experts based on long-term experience in grinding machine research and development, and based on the usage and suggestions of 9518 grinding machine users. This model adopts the latest patented technologies such as bevel gear integrated transmission, internal thin oil lubrication system, and curved air duct It is mainly used for grinding various non flammable and explosive mineral materials with Mohs hardness below level 9 and humidity below 6% in industries such as mining, building materials, chemical industry, metallurgy, thermal power, and coal. The fineness of the finished product can be adjusted freely between 30-400 mesh.

Highlight advantages
1. Cone gear integrated transmission: Traditional grinding machines require additional reducers to drive the main shaft through couplings, which makes it difficult to center during installation and can easily generate noise, reducing efficiency. The MTW series European trapezoidal grinding machine adopts a cone gear integrated transmission, which is more compact in structure, easier and faster to install and adjust, and greatly increases efficiency.
2. Internal thin oil lubrication system: The traditional lubrication form of the grinding machine is grease lubrication, which has high lubrication resistance, high temperature rise, and short bearing life. The MTW series European trapezoidal grinding machine uses an internal oil pump, which can achieve lubrication of the main shaft bearings and bevel gear shaft bearings without the need for additional oil pumps or lubrication stations.
3. Curved air duct: The air ducts in traditional grinding machines are all straight plate air ducts. This structure has disadvantages such as resistance caused by the impact of airflow on the air duct plate, large energy loss due to the collision of airflow molecules, and easy generation of eddy currents leading to air duct blockage. The MTW series European trapezoidal grinder uses a curved air duct with a smooth tangential airflow inlet, low resistance, and an internal outlet direction that is conducive to material dispersion and less prone to material blockage.
4. Surface replaceable blade shovel: Traditional grinding machine blades wear out quickly, and the shovel is an integral blade. After the blade wears out, it needs to be replaced as a whole, which wastes materials and increases downtime for replacement. The MTW series European trapezoidal grinding shovel adopts high wear-resistant alloy material for the blade, with a long service life. When replacing, only the blade part needs to be replaced, which improves the material utilization rate. In addition, traditional flat shovel blades accumulate materials on a single surface after being lifted, causing severe wear in the middle of the grinding roller and ring. Curved shovel blades can guide materials towards the vertical surface, allowing the upper, middle, and lower parts of the grinding roller and ring to be ground evenly, while also increasing the effective working area and thus increasing production.
5. Isolation type cyclone powder collector: An isolation structure is used between the inner cylinder and the mixed gas powder flow, which can effectively improve the powder selection efficiency and accuracy.
6. Non resistance inlet volute (small observation door without eddy current): The internal door panel of the inlet volute observation door of traditional mills protrudes outward and is not on the same plane as the inner surface of the inlet volute, which easily generates eddy current effect and increases system energy consumption. The MTW series European trapezoidal grinder adopts an internal door panel with the inner surface of the intake volute on the same curved surface, which can effectively avoid eddy current effects.
7. Exquisite appearance: The European version of the grinder not only adopts many advanced structures inside, but also features a beautiful curved structure design on the outside, making the entire machine look more exquisite and sophisticated.
Working principle
After the large block material is crushed to the required particle size by the jaw crusher, it is sent to the storage hopper by the elevator, and then uniformly and quantitatively continuously sent to the main grinding room for grinding by the vibrating feeder. The ground powder rises with the airflow of the fan and is classified by the powder selector. The powder with the appropriate fineness flows through the pipeline into the large cyclone collector for separation and collection, and is discharged through the powder outlet valve to obtain the finished powder. The airflow is drawn into the centrifugal induced draft fan through the return duct at the upper end of the large cyclone powder collector. The entire airflow system of this machine is closed and circulates under positive and negative pressure. There is a certain amount of water content in the material being ground in the grinding room, which generates heat during grinding and causes gas evaporation in the grinding room, changing the air flow rate. In addition, the joints of various pipelines in the whole machine are not tightly sealed, and external gas is sucked in, increasing the circulating air flow. To achieve air balance, the exhaust pipe between the fan and the host is adjusted, and the excess gas is introduced into the bag filter to collect the powder brought in by the residual gas. The residual gas is purified and discharged.
