The fabricated grinding chamber is constructed in 316 stainless steel with a high quality 0.8 micron Ra finishes available. Higher quality finishes are available for specialty applications. The access door is hinged to the grinding chamber and is secured with a tri-clamp connection for easy and quick inspection and cleaning. The bearing housing is a cantilevered design and includes maintenance free, sealed for life bearings. There are double lip seals and a gas purge between the drive and process areas to eliminate material contamination and premature wear to drive components.
Designed, Manufactured and Assembled in the USA
The Mikro LPM® Laboratory Pin Mill is an innovative mill, based on the design of a Mikro Pulverizer® Hammer & Screen Mill. It is designed, manufactured and assembled in the USA and comes with our pledge to performance and guaranteed dependability.

[post_content] => With Alpine High Pressure Roller Mill products are produced with a precipitous granule distribution. The high pressure roller crusher is also called roller crusher or roller press.
The significant difference of high pressure roller grinding compared with compaction is that the press forces between the rollers are lower because no new adhesive forces need to be created.
The mill feed is transported to the most narrow gap by the counter rotating rollers through friction effects. Both rollers are pressed against each other using hydraulics. This milling force is transferred to the mill feed. Through selective contact of the individual granules are created at extremely high inner tensions which lead to fractures.
The use of the optimal milling force leads to compact mills with extremely low energy requirements. Because only the outer particles of the material bed have contact with the surface of the rollers, milling that is almost contamination-free is possible.
High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the Moh's hardness scale, metals and metal alloys. High Pressure Roller Mills are used in continuous operation or in a closed circuit with screening machines or classifiers.

Rotor Types
Hosokawa Flash Dryers are available with a choice of three rotor types, selected according to product characteristics and specific process goals. Each rotor offers distinct advantages to suit a wide range of applications:
DMR Rotor
A high-speed multi-blade rotor designed for strong dispersion, generating a powerful air vortex with tip speeds of up to 110 m/s. Ideal for maximum dispersing performance.
MDH Rotor
A horizontally driven rotor with swinging hammers for intensive grinding. Recommended for processing slurries and pastes requiring strong milling.
MDV Rotor
A vertically driven grinding rotor that gently disperses wet agglomerates and solids. Suited for mild dispersion and grinding of heat-sensitive products.
