Ultrafine Mill

What is an ultrafine grinding mill?

An ultrafine grinding mill (also called an ultrafine grinder, micro powder mill, or superfine powder grinding mill) is an upgraded version of the traditional Raymond mill.

It mainly provides extremely fine powder or micron-sized particles for construction, metallurgy, mining, chemical industry, cement, construction, fertilizer, ceramics, and other fields.

Application scope of ultrafine grinding mill

The ultrafine grinding mills are specialized in grinding non-flammable, explosive, and brittle materials with Mohs hardness smaller than 6 and moisture content less than 6%.

• Feed size: <40 mm
• Capacity: 0.4–40 tons/hour
• Output size: 0.25–0.015 mm (60–800 mesh)

The following are FTM Machinery's popular ultrafine powder production lines:

• Limestone Grinding
• Kaolin Clay Grinding
• Talc Powder Production
• Calcite Fine Powder Production
• Phosphate Rock Grinding
• Barite Grinding
• Calcium Carbonate Powder Production
  

The structure of the ultrafine mill

The FTM Machinery Ultrafine Mill has a vertical structure, occupies a small area, and integrates crushing, classification, and static pressure.

FTM Machinery strives for perfection in every configuration. The output, fineness, and environmental protection of the fine powder grinding machine far exceed any fine powder grinding machine:

• The modular separator design can adjust the fineness of the finished product between 60-800 mesh and the one-time screening rate can reach D97≤5μm.
• The high-pressure spring device improves the grinding force of the grinding roller on materials, and the output is 45% higher than that of the air current mill and stirred mill.
• The grinding roller and grinding ring are made of special wear-resistant steel. The consumption of wearing parts is low and the service life of ordinary grinding mills is longer.
• There are no loose parts such as rolling bearings and screws in the grinding chamber, making the grinding mill machine run smoothly and reducing the failure rate.
• The multi-stage sealing and dust collector can eliminate noise and achieve more than 99% dust removal effect.

How does an ultrafine grinding mill work?

In addition to the ultrafine grinding mills, the bucket elevator, classifier, and pulse dust collector are also important components of the ultrafine powder production line. This can ensure efficient and environmentally friendly production.

First, the bucket elevator transports dry powder vertically from the hopper to the fine powder grinding mill with minimal space and maximum safety, and the lifting height can reach 25–80 meters.

When the grinding mill is working, the material falls into the grinding chamber under the action of centrifugal force. It is repeatedly squeezed, broken and ground by the roller, and then becomes fine powder or micro powder.

The ground powder enters a classifier for screening.

After being collected by a pulse jet dust collector, the powder is discharged through the discharge valve. The dust collector adopts an offline dust cleaning method, which can collect and remove 99.99% of industrial dust without shutting down the system, achieving environmental protection and safe production.
