5000t / d production line of raw material preparation using RMR57/28/555 vertical roller mill. In the trial production period, there are often caused by improper operation of bucket elevator loop current is too high, resulting in crushing bucket elevator, mill jump stop the phenomenon, not only to field a larger increase in the dolomite processing manufacturer in China workload of staff, also affected production. Through the operator and the constant review and practice, the current form of a set of effective control measures to effectively prevent the occurrence of such phenomena.
Problems outside the circle bucket elevator model: NSE300 × 33350, transmission capacity of 450t / h, motor power 75kW, rated current of 140A, the alarm value of 150A. In actual production, often due to sudden changes in raw materials, incoming instability and other reasons, the status changed to wear, resulting in material outside the circle, resulting in high current hoist. Early in the production, operation of commonly used method is a rapid reduction of the volume of feed at the same time increase the grinding pressure, appropriate to reduce the speed of the powder, so that as many as possible with the gas from the powder mill, mill to reduce the volume within the material, thereby reducing the external of recyclable materials. However, in practice found that such methods of operation to adjust for too long, large number of materials from outside the mill, will eventually cycle crushing bucket elevator. As the hoist is a chain of relations with the vertical roller mill, skip hoist will stop after the mill shut down?

Main benefits of ultrafine mill are:

The hot air in the main unit can contact with the materials Industrial mining machine directly, which is of high drying capacity and energy saving.

• The special designed vertical grinding rollers help to short grinding time and protect the rollers and internal structure.
• The whole cast steel shell increase the reliability of vertical roller mill.
• According to the elevator, all the working parts can be examined and fixed easily.
• As an integration of crushing, drying, grinding and classifying, the compact LM series vertical mill works with high efficiency.

Main features of ultrafine mill are:

• Premium Efficiency High Torque Motor
• Three Stage Reducer
• Solid Steel Grinding Screw with bolt on replaceable liners
• Automatically greased bearings
• Orebed Magnetic Shell Linerse
• Modular Mill Body
• Access Door for Vertical coal mill in UAE maintenance and screw removal
