XZM Ultrafine Grinding Mill

Ultrafine powder, wide applications, excellent environmental effect

ZENITH’s XZM Ultrafine Grinding Mill is widely used for superfine powder production. The output size can reach 2500mesh (5um). It is suitable to grind soft or medium-hard materials whose moisture is below 6%. Materials should be non-explosive and non-flammable such as calcite, chalk, limestone, dolomite, kaolin, bentonite, etc. The size of the finished product can be adjusted between 325-2500 mesh.

Materials:Calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc.

Product Advantages

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 mill.

The multi-head cage-type powder selector can be configured. The fineness can be adjusted between 325-2500 meshes, and the screening rate can achieve D97≤5μm once.

The lubricating device is installed outside of the main shaft, so that lubrication without shutdown can be realized, and the production can be continued for 24h.

Silencer and noise elimination room are configured to reduce noises. Besides, the operation is organized by conforming to national environmental protection standards.

Working Principle of XZM Ultrafine Grinding Mill

After large materials are crushed to smaller ones, the hoister 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, 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. 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 powders 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, so it is quite friendly to the surrounding environment.
