Inheritance of Classical Design, Innovation of Science & Technology

MTM Medium-speed Grinding Mill adopts the classical pendulum rollers of Raymond Mill on the one hand and change the spring connection structure innovatively on the other hand, which can not only avoid the terrible impact of large materials on the axis and bearings, but also enhance the crushing strength of grinding rollers so as to increase the yielding.

Lower Electricity Consumption, Higher Economic Profits

Under an ideal circumstance, MTM Medium-speed Grinding Mill consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball grinding mill of the same level by over 60%.

Impeller-type Energy-saving Fan Having Higher Efficiency

SBM adopts the high-efficiency impeller energy-saving fan, and the working efficiency of which can reach 85% or above while traditional grinding mills equipped with straight blade fan can reach only 62% of air inducing efficiency. Under the equivalent production requirements, MTM Medium-speed Grinding Mill can realize better powder separating and lower power consumption.

Lower Energy Consumption – Cambered Air Duct

MTM Medium-speed Grinding Mill uses the cambered air duct with low resistance. By this, air flow enters the grinding mill tangentially. 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 which can avoid material piling, effectively reducing energy consumption of the system.

Digitalized Processing, Higher Precision

There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

Sufficient Supply of Spare Parts, Worry-free Operation

SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

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 MTM Medium-speed 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.
