MTW European Grinding Mill is innovatively designed through deep research on grinding mills and development experience. It absorbs the latest European powder grinding technology and concept, and combines the suggestions of 9158 customers on grinding mills. This grinding mill perfectly satisfies the production demands of the customers on 200-33μm (80-425Mesh) fine powder.

Working Principle

After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of MTW European Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. 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, SBM 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.

    End port, rail coal mismatch to gain India prize

    The participants of South Africa’s coal value chain needed to put an end to the misalignment of port over capacity and rail under capacity, Webber Wentzel mining partner Manus Booysen said on Monday.Booysen, just back from a major coal conference in New Delhi, called for coal value chain participants to meet urgently at the highest level to take full advantage of the colossal opportunity that was rapidly building up for the export of additional coal to an energy-hungry India.

    Product Application

    As everyone knows that MTW Milling Machine is an ideal machine for grinding barite, limestone, mica, talcum, quartz, calcite, granite, porcelain clay, basalt, gypsum, gold, iron ore, bauxite, copper, cement, coal etc. We believe it will play a huge role in powder making industry of construction, mining and paper-making and so on.

    Product Advantage

    • All-in-one machine

      This kind of machine can form the closed production line with classifier products to create a variety of size of particles. And we can also increase the productivity of Ball Mill by 35%-40% before the ball mill.

    • Substantial usage efficiency of the wearing parts

      From top to the end of this grinding roller are evenly wearing , which have extended its service life.

    • Large crushing and thin powder ratio

      Equipped with the vibrating screen, this variety of MTW Milling Machine can grind the elements to thin supplies of less than 2mm or 1mm, which have increased the production of Raymond mill by 30%~40%.

    • Desulfurization of the power plant

      MTW Milling Machine can grind the calcium carbonates to the thin powder of less than 2mm or 1mm so that the desulfurization is improved.

    • Refractory block, unburned pieces

      The crushed products of MTW Milling Machine will be used to produce the particles such as refractory block, unburned pieces, etc. And that’s have the superior match with the powder.

    Operational Principle

    Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rotates with main shaft and swings freely meantime, this bring a large centrifugal force, which scatters bulk materials evenly in grinding intermediate layer between central roller and ring. The bulk products are grinded into powder and fall on the bottom, and then discharged from discharging opening under the impact of synchronously-rotating scraper.
