Optimise your results with a high pressure grinding roll, an ultra energy efficient way to crusher fine particles. The F-series HPGR, developed by FL, incorporates a combination of engineered solutions and optimised components. Our design is derived from our years of maintaining these machines in the field and aimed at decreasing ...
Whilst the test results for the HPGR and VRM are not directly comparable (due to different degree of size reduction), both demonstrated the potential for considerable energy savings compared to conventional ball milling. The HPGR and air classification circuit used 20 - 30 % less energy than the HGPR, screen, ball mill circuit.

HPGR Roll Crusher. The MechProTech High Pressure Grinding Roller Crusher comes with a standard design of twin 950mm diameter manganese steel lined rollers and a width range of 300, 600 and 900mm. Wear plate feed chute and sealing arrangement. Mild steel painted support frame complete with heavy duty bearings with threaded gap adjustment.
NLMK began implementing HPGR technology in each of the plant's four process lines in 2016. The first four grinding rolls supplemented traditional cone crushers and ball mills, and enabled the plant to boost the productivity of the sections by 12.5% and to grow iron ore concentrate output by 1 million mt to 16.6 million mt/y.

A series of comminution tests was carried out to evaluate three multi-pass HPGR circuits and a jaw crusher-ball mill circuit. Combinations of HPGR units (1.0 m and 0.25 m diameter), jaw crushers and Bond ball mills were used to grind a 32 mm top size porphyry copper feed (BBWI = 12.1) to a product P80 size of about 150 m.
The HPGR comminution was carried out using a CLM-250 × 100 unit equipped with 250 mm diameter and 100 mm width rolls (Leejun Industrial Co., Ltd, China) and operated under three roll pressures (3.5, 5.5 and 6.5 N/mm 2) with the roll speed of 0.5 m/s.The equipped programmable logic controller (PLC) was used to ensure the production stability of HPGR.
HPGR Performance Comparison. Within communition circuits, High-Pressure Grinding Rolls (HPGR) are increasingly replacing traditional milling conventions such as (S)AG or rod and ball mills for hard rock reduction. This …
The high pressure grinding roll (HPGR) circuits are becoming common, and they can be considered a variation on the classical single stage ball mill circuit where the final stage of crushing is the HPGR. Simulating HPGR has two differences from a classical SSBM circuit with cone crushers: first is that the crusher product tends to be finer (~4 ...
HPGR can replace the tertiary crushers or, as a pre-grinding stage, provide feeds for ball mills [,, ]. In an HPGR, energy consumption for a particle size reduction is based on the existing pressure between the floating roll (the moveable roll) and the fixed roll in the frame. This pressure can be varied from 5 to 18 MPa.
The HPGR can be used in hard rock mining but not on soft ores or wet sticky ores and wet climates. Otherwise the HPGR will produce pancakes (bogged up). The CADIA East Project (Newcrest mining in Australia, 2011) introduced a secondary crushing (cone crushers) followed by tertiary crusher HPGR in front of the incumbent SAG Mill This increased ...
