The Raymond mill is very expensive and sprayed almost entirely the product leave. The roller mill is very sensitive to environmental moisture and high circulating load. Our material contains 50% calcite, completely dry. The air classification was the best selection for the dry sand.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
The efficiency of the basic Roller Mill System becomes a highly efficient means of removing moisture from the raw material by the simple addition of an air heater (G) as shown in color. Further refinements to the heater system allow the Williams Roller Mill to process hazardous dusts in a controlled low oxygen atmosphere.

The present invention relates to a system and to a process for dry recovery of iron oxide fines from iron-bearing compacted and semi-compacted rocks, comprising means for primary (5), secondary (6) and tertiary (7, 7') crushing for the purposes of preliminary reduction of the particle size of ores containing the iron oxide fines in compacted and semi-compacted rocks; means …
Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time.
(3) The roller part is the hardcore part of the crusher. The connection between mill roller and main shaft adopts key and taper sleeve, which is dismounting easily. (4) The gap between two rollers can be read from staff. The place where there is a hole under the staff is the zero reference line. The gap is 10 mm when the machine leaves the factory.

EM Mill At the heart of its grinding system is the EM Mill, bringing the functions of grinding, drying and classifying together into one compact unit. The Claudius Peters EM Mill produces highly uniform product quality with the fully automated control system managing the complete pro-duction cycle from start up to shut down.
HISTORIA DE LOS HPGR • El origen de la tecnología HPGR, se remonta a los inicios del siglo XX, donde se utilizó en la briquetización de carbón. • En el año 1985 la tecnología fue introducida en la industria del cemento. Actualmente, éste es el sector industrial que utiliza mayor cantidad de molinos HPGR en el mundo.
The HPGR and air classification circuit used 20 - 30 % less energy than the HGPR, screen, ball mill circuit. While VRM was estimated to use 10 - 30 % less energy (depending on the type of VRM) than a ball mill circuit for a similar degree of comminution.
Capacity can exceed 6,000 t/h when compared to present maximum HPGR 2.8 m dia. roller size 18. Capacity is controlled with variable speed drives and machine dimensions 19. Runs 6-10 times as fast as an HPGR, where HPGR is limited to ~1 m/s roller surface speed 20. Advantage of reducing carbon footprint and operating costs 21.

Recent gains (~30%) using High Pressure Grinding Rolls (HPGR) and Vertical Roller Mills (VRM), in theory and practice, are based on Prof. Klaus Schönert's academic studies [1] (1979-1996) on rock breakage physics. More recently, University of British Columbia (UBC) Prof. Bern Klein's studies (2006-
Due to the physico-mechanical properties of granular materials, an excessive moisture content will result in lower throughput rates due to the increased possibility of material slip on the rollers. On the other hand, material that is too dry will prevent the formation of a competent material bed in the crushing zone.
For this purpose, the HPGR offers the advantage that the HPGR's discharge contains considerable amounts of finer product at a reduced material strength/reduced Bond work index which, in turn, increases the capacity of the ball mill.
However, the moisture level is critical to achieve an increase of 300 to 400 cm 2 /g for the reason of the slippage (drifting) among particles covered by water, when pressed between the rollers. The moisture content increase reduces parabolically the HPGR throughput, especially on the level above 7% (typical for the pelletizing process).
agents. polycom ® HPGR grinding is based on the principle of ... • raw materials with moderate moisture content ... Compared to a roller mill, it is thus able to save up to 20 percent of the energy required for grinding; compared to a conven-tional ball mill, it can even save up to 50 percent. ...

High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
A first survey of grinding with high compression roller mills. International Journal of Mineral Processing, v. 22, p. 401- 412, 1988.). Also, it should be pointed out that no product in any test experienced flake formation, which may be explained by the lack of moisture in the material, as it comes from electrofusion furnaces.
