Proven milling and grinding solutions to optimise your productivity

Our HPGR is flexible enough to be highly suitable for both brownfield expansions and greenfield installations. It exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles. This high pressure also creates a large quantity of fines and causes the formation of microcracks in the larger particles, lowering the Bond work index of the ore and reducing the ball mill power required downstream. 

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. It is the most efficient comminution product in grinding and milling applications. 

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation. 

The mills can be operated in open circuit, feeding downstream secondary grinding, or operated in closed circuit as single stage mills generating a finer product size. Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. 

Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill designs in order to provide the most robust, safe, and efficient grinding mills available. 

The FLS Tower Mill (FTM) reduces energy and media consumption, while minimising water usage in secondary and tertiary wet grinding of minerals. The major design feature of the tower mill is a central agitator screw, the only moving machine compo- nent in contact with the slurry and steel media, which allows size reduction by attrition. This arrangement reduces energy consumption in fine grinding of minerals by 25% to 50% when compared to traditional horizontal ball mills for the same feed and product size. 

Alternatively, the VXPmill is a vertically oriented stirred media mill that is open to the atmosphere. This mill is designed with a modular impeller that has removable discs and spacers. Slurry enters at the bottom, travels upward through the mill chamber, and overflows through a media retention screen at the top. The rotating polyurethane discs activate inert ceramic grinding media inside the milling chamber. This activation fluidises the media bed which performs an attrition grind on the particles in the slurry. 

VXPmills operate at a power intensity that is higher than low-speed mills and overlaps that of high speed mills. This allows the VXPmill to be customised to a wide range of grinding applications.
