PRODUCT INTRODUCTION

Ultrafine Grinding Mill is mainly suitable for calcite, calcium carbonate, dolomite, talc and other non-flammable and explosive materials with Mohs hardness below 9 and humidity below 6%.
Ultrafine Grinding Mill is a new superfine powder (325-2500 mesh) production equipment developed through accumulating years of experience in grinding mill production, absorbing Swedish advanced machine manufacturing technology, and undergoing many years of tests and improvements. The Ultrafine Grinding Mill is the result of combination of advanced Chinese and Swedish technologies. Meanwhile, it symbolizes the new development and new science in the grinding world.

Features

Higher Yielding, Lower Energy Consumption

Newly designed grinding curves of grinding roller and grinding ring further enhance the grinding efficiency of SCM Ultrafine Grinding Mill. With the same fineness and power, the production capacity is 40% higher than that of jet grinding mill and stirred grinding mill, and the yield is twice as large as that of ball grinding mill. However, the system energy consumption is only 30% of the jet grinding mill.

Adjustable Fineness Between 325-2500meshes

Ultrafine Grinding Mill's cage-type powder selector adopts German technologies, which effectively increases the precision of powder separation. In addition, multi-head cage-type powder selector can be configured according to the users' requirements on yield, fineness and sieving rate. The product fineness can be adjusted between 325-2500 meshes, and the screening rate can achieve d97≤5μm once.

No Rolling Bearing & Screw in Grinding Chamber

There is no rolling bearing and screw inside the chamber of Ultrafine Grinding Mill, so users are free from worries about damages on bearing or its sealing parts, and there is no machine damage problem caused by loose screws. The lubricating device is installed outside of the main shaft, so that lubrication without shutdown can be realized externally, and the production can be continued for 24h.

Dust Removal by Pulse Collector Makes Operation More Eco-friendly

Ultrafine Grinding Mill is equipped with efficient pulse dust collector, so no dust pollution generates during operation of the entire milling system. Silencer and noise elimination room are configured to reduce noises. The production is organized fully according to the national environmental protection standards.

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

SPOM, 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 hammer crushers break large bulky materials to smaller ones, elevator works to send materials to material bin. Next, materials are sent to the grinding mill evenly and they would fall onto the dispersing plate firstly. When the grinding mill runs, dozens of grinding rollers start to rotate and roll. Under the action of centrifugal force, materials on the dispersing plate are then thrown to the rim and drop to the grinding chamber. In the circuit, materials would be squeezed and ground. After being ground several times, materials are blown into the powder selector by airflow. 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. Some remaining powders would be collected by impulse dust remover and they may stick to the surface of filler-bag. So, next, high-pressure airflow controlled by the impulse valve blows the filler-bag to make it swell and shake violently. This sudden shake can help kick off materials on the filler-bag and collect them as finished products. After filtering, the airflow would be discharged to the air. This system adopts an open circuit and runs under negative pressure.
