MTM Medium-Speed Grinding Mill

Low energy consumption, high yielding and high returns

ZENITH’s MTM Medium-speed Grinding Mill is designed by our own engineers and technical workers based on many years' research of grinding machines. It adopts world-leading powder processing technology. Our MTM Grinding Mill collects many advantages of various mills all over the world. It is the ideal substitute of the traditional mills like Raymond mill, high-pressure hanging roller mill, ball mill, etc.

Materials:Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

Product Advantages

The innovative change of the spring connection structure not only reduces shock of large materials on the aixs and bearing, but also enhances crushing strength of rollers.

MTM Grinding Mill consumes less electricity compared to traditional mills. Its electricity consumption is lower than that of ball mill of the same level by over 60%.

Compared with traditional straight air ducts, the inlet of this air duct is smooth with little resistance and the outlet is easy for the dispersing of materials.

The high-efficiency impeller energy-saving fan is used whose working efficiency can reach 85% or above while traditional straight blade fan can reach only 62%.

Working Principle of MTM Medium-Speed Grinding Mill

After large materials are broken to smaller ones, the hoister works to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber. After grinding, materials are blown away by airflow to the powder concentrator for classification. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure.

Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, ZENITH arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.
