Ulm Ultrafine Powder Grinding Available D50: 3 - 45 Umturbo Rotor Mill

Product Description

ULM Rotor Mill

Multi-layer grinding head, strong shearing force and dispersing force

Especially suitable for the dispersion and reduction of agglomerated materials, such as: light calcium, kaolin, aluminum hydroxide, magnesium oxide, and ultrafine grinding of heat sensitive materials such as polyvinyl alcohol, PVC, PE, cellulose. Widely used in non-metallic minerals, chemicals, fuel, feed, food and other industries.

FEATURES AND ADVANTAGES

• Available D50:3~45μm
• Suitable for raw materials with Moh's hardness lower than 3, especially suitable for tough materials such as fiber and plastic
• The grinding rotor comprises multi-layer grinding disc and several grinding blades, high grinding efficiency.
• Durable alloy blade, replaceable.
• Distance between the grinding cutter head and the ring gear can be adjusted to adapt to the grinding of different materials
• Compact structure and small occupation. easy to disassemble and clean
• Lower installation power, wide application, high cost-performance.
• Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
• PLC control system, easy operation.
• External cooling air can be used to achieve low temperature grinding, especial in heat sensitive materials.
• Can be used in series with multi-stage classifiers to produce products with multiple sizes at one time.
• Explosion-proof design can be selected to meet the requirements of ultra-fine grinding processing of flammable and explosive oxide materials.

WORKING PRINCIPLE

The material is uniformly fed into the grinding zone by feeding system and strongly impacted by the high-speed rotating grinding disc.

The grinding rotor is composed of a multi-layer grinding disc and a plurality of grinding blades, the material is subjected
to various grinding forces such as shearing, collision, friction etc and finished grinding.

The qualified materials are collected into the collection zone with the ascending airflow, the coarse materials are returned to the grinding zone for secondary grinding.

About Our Equipment

 

                                           ALPA can provide dry ultrafine grinding equipment suitable for various materials

Impact mill

High efficiency, has two milling effects of impact and grind, large milling ratio, simple structure, stable operation, suitable for milling medium-soft hard materials.

Jet mill

Uses the high speed turbulence airflow generated by compressed air or superheated steam as milling power. Impact extrusion, friction and shear between the particles or between the particles and the fixed plate occur, so as to achieve milling.

Ball mill + Classifying

The ball mill and classification production line refers to a complete set of milling system composed of Ball mill, cyclone, dust collector and fan.
