nickel ore processing sag mill feed bin
Lac Guéret Graphite Project, Québec
The crushed material will be discharged into the semi-autogenous grinding (SAG) mill feed bin conveyor, before being delivered to the SAG mill for grinding. Lac Guéret’s SAG mill will operate in a closed circuit with a screen, and the mill discharge will be pumped to a vibrating screen. Oversize ore material will be re-ground in the ball

Dynamic Modeling and Simulation of SAG Mill Circuits with
ore particles. In a SAG mill, external grinding balls are added in the chamber to aid in the grinding process. Napier-Munn (Napier-Munn et al., 1996) classified the breakage mechanisms occurring within AG/SAG mills into three categories: high energy related impact breakage, low energy related abrasion, and attrition.

Humboldt mill a success for Lundin Mining's Eagle mine
The mill, currently operated by Lundin Mining, processes the nickel/copper ore from Eagle and performs the concentration through several stages of flotation. Originally built in 1954, Humboldt began operations as an iron ore processing facility, and was converted to a gold processing plant during the 1980s.

From there, it is further transported to the SAG mill feed surge bin. The ore from the mill feed surge bin is reclaimed by two 1,067 mm wide by 15,000 mm long apron feeders onto the SAG mill feed conveyor at a nominal rate of 172 t/h. The stocking and re-handling system for the crushed ore includes the following major components:

Schenck Process Supplies Mill Discharge Screens for Cobre
Like Schenck Process Beast SAG mill screens, the excitation force of the new SLD4397DXX ‘mega’ screen is delivered by four DF704 exciters mounted on 2 unitary beams. But unlike the Beast, the new screen’s drive assembly incorporates a unique twin gearbox arrangement driven via a single motor, ensuring effective exciter phasing.

If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, the SAG mill usually drives the discharge arrangement. This is because the SAG mill is usually of larger diameter and may have a requirement for screening of pebbles to protect the mill discharge pumps and cyclones, and to

SIMULATION-DRIVEN DEVELOPMENT FOR COARSE COMMINUTION PROCESS
the ore processing consists of a three-stage crushing plant followed by SAG-mill and Ball-mill circuit. The mine is expected to have a change in ore characteristics as the mining process is moving from open pit to underground. The tested new ore is changing in its grade, recovery, material properties (increased hardness).
