Used in mining applications for the last 30 years, High Pressure Grinding Rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
1. Introduction. Schönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success resulted ...
For extreme efficiency and high equipment availability, look no further than roller press technology and products from FL. The roller press is a uniquely designed comminution tool, in that feed ore is exposed to extremely high pressure for a short amount of time resulting in .
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill

HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .

Disk Mills are suitable for fine grinding of medium particle sizes of soft to hard, brittle and temperaturesensitive solids. The material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth.
Application: Highpressure suspension grinder is widely used in mining, meatallurgy, chemical engineering, building materials to grind finely more than 280 kinds of material with Mohs hardness less than and the moisture below 6%.The granularity of finished product is controlled between 80 and 425 meshes, and it can product 3080 meshes coarse powder by adding some special device.
If it is used for crushing, the Kompaktor is also called high pressure roller mill. Compacting is understood to be the compression of powder between two synchronised, counter rotating rollers. Here, adhesive forces between the product particles are created under high pressure between the rollers.
Application of High Pressure Grinding Mill. YGM series High Pressure Grinding Mill is the new type High Pressure Grinding Mill of our company, which is suitable for processing various nonflammable and nonexplosive mineral materials with Moh''s hardness less than and humidity less than 6%.
Explosion safety for mills and grinding plants. Inherently, every mill has metallic parts that approach and touch each other at high velocities a high probability for the creation of potential ignition sources. If you observe the prerequisites for a dust explosion, a mill offers all the necessary components: Dust, a closed container ...
004 Outotec Grinding technologies A full range of mills for wet and dry grinding The demands of hard rock mining and industrial minerals operations require a diverse range of grinding mills for both wet and dry applications. AG and SAG mills are currently the industry standard for primary milling and Outotec provides both high aspect or low
The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
