SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...

By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the ...

A longer lasting mill liner means less downtime for maintenance or new liner installation. A mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. Safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.

sag mill control fl - kosten-hekwerken.be. The SAG mill feeds two ball mills each 26 ft. in diameter × 40 ft. long (EGL), each driven by a 16,400 kW drive. The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru (Garcia & Villanueva, 2013 [1]). get price

Expert mill control at AngloGold Ashanti SAIMM. The ROM SAG mill circuit a brief description The typical ROM SAG mill circuit is depicted in Figure 1 The circuit is usually closed with either a screen or more commonly a cyclone for product size classification The focus of control can be divided into two parts viz the mill and the cyclone The importance of cyclone performance should

The SAG mill accepts 3 the primary crushed feed ore and operates in closed circuit with pebble crusher. SAG mill discharge passes through grates and screened by a trommel with the oversize being recycled by conveyor back to the SAG mill. Combined product from the SAG mill (trommel undersize) and the Ball mill discharges into a

The following optimisation strategies are recommended to achieve high-level process control: Understand the key process drivers affecting the SAG mill performance by assessing the SAG mill performance using comminution models. The objective is to identify the key precursors of the process variables (i.e. ore properties such as competency)
