Results from this research showed that operating the first-stage HPGR in open circuit and the second stage in closed circuit with a 710µm screen, resulted in a circuit energy requirement of 14.85kWh/t, a reduction of 9.2 and 16.7% over the HPGR / ball mill and cone crusher / ball mill circuits, respectively.
Ball mill tests were carried out in a mill with an internal diameter of 305 mm and a length of 305 mm, with conditions shown in Reference . A HPGR test was conducted using a unit of 25 cm diameter rolls and a width of 15 cm that was fully equipped to control and record the hydraulic pressures, which runs at 40 bar.
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.

The raw materials required to manufacture HPGR are metal, steel, rubber, plastic and other basic materials. A number of sub-components required for the manufacturing process are produced by tier 2 suppliers operating on small margins.
The HPGR-ball mill circuit comprises a reverse-closed secondary crushing circuit prior to a closed HPGR circuit, followed by a reversed-closed ball-mill circuit with cyclones (See Figure 2). The vibrating screen decks were set to an aperture size of 32 and 4 mm for the secondary crushing stage and HPGR screen circuit, respectively.

HPGR specific throughput (" m-dot ") values observed in both the UBC and Corem testing were consistent between the two test facilities, peaking at approximately 200 ts/hm 3 .
A HPGR is principally a horizontally mounted double-roll mill, equipped with hydraulic pistons on one side, pressing against the floating roll - the other roll being fixed in the frame.
Source: Polysius Polycom HPGR Brochure. An HPGR can reduce kwh/t energy consumption when working in conjunction with another mill, usually a tube mill. 3 A savings of around 1.8-2.5 kwh/t for clinker and 2.5-3.8 kwh/t for GBFS can be obtained. 3

this mill is employed all around the world for the grinding of cement raw material, cement clinker and granulated blast furnace slag. Since the POLYCOM® was introducted by Polysius onto the market in 1985 more than 250 units have been sold, so that almost half of the approximately 500 mills operating worldwide on
HS Code. 8482400000. Product Description. High pressure grinding rolls / roller / roller shaft. CITICHL roller presses offer rollers with appropriate wear protection for almost all applications in the cement and minerals industry. The two-part rollers consist of shaft and tire, single part rollers are used for high temperature grinding.
In HPGR-ball mill circuit, when the compression of the grinding efficiency of HPGR and ball mill circuits separately, it can be seen that HPGR circuit is very efficient. Although VRM is also very effective grinding equipment, it consumes too more energy to transport the material from grinding table to dynamic separator by air inside the mill.
Where HPGR technology has replaced traditional methods of crushing and grinding such as SAG or ball mills, customers have seen energy savings of up to 40%, and substantially improved mineral liberation. Find out more about the Enduron …
In a Malaysian project, through the application of HPGR and a 400tph ball mill, the company achieved a fineness of 4162-4712cm 2 /g according to Blaine, at a total specific power consumption of 32.4-37.1kWh/t. Topnewer's Elite Yang considered the advantages of using ceramic grinding balls (CGB) instead of high-chrome steel inside a ball mill.
The HPGR drive system is made up of electric motors and planetary gear boxes installed at the drive end of each roll. The gear boxes are connected to a system of torque arms. Depending on the application, an HPGR may be laid out for constant-speed operation or …
However, the overall energy reduction in a HPGR-mill configuration can be greater than 30%. The benefits of HPGR in mineral beneficiation are visible at the level of useful mineral liberation. Microscopic analysis has found [ 12 ] values of 75% to 95% for copper minerals liberated from sulfide ores, depending on the operating pressure value.
The mill content is defined as the accumulation in the mill which is the combination of the new feed to the system and partially broken material still within the system. For the HPGR operation, the mill content was considered as the material between the rolls to be crushed.
