Lateral drive . Our freshly redesigned MAAG® GEAR LGDX is a highly functional, compact lateral drive system for horizontal mills. With its smart casing design, it can be positioned either on the horizontal axis of the mill or at 40° underneath it, delivering a more compact design with lower construction and foundation costs.
Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (, a 34ftdiameter mill shell would have 68 shell lifters). This is also called a 2D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters

AG Mill and SAG Mill. Feeding size: ≤25mm. Capacity: .65615t/h. Output size: Applications: It is commonly used in the mineral processing industry and ferrous and nonferrous metal ore and nonmetal ore processing plants. It can also be used in cement plant, refractory plant, fertilizer plant and smelting plant.
remedial measures [1,2]. The causes of both the SAG and ball mill drive faults were related to the stiffness of the drive components. During this work, the characteristics of the SAG mill system were measured. The resonant frequency of the foundation was determined using an amplitude decay technique. Vibrations in the SAG mill stator
The Collahuasi motor was for a 40 ft SAG mill. The Antamina 38 ft SAG mill was also driven by an ABB motor and the hanger plates had not failed on that machine after several years of operation. Similarly, the Sossego motor for the 38 ft SAG mill had not failed. It too had an ABB motor and it had operated longer than the Collahuasi motor.
Bordi: "We are increasing the 'tools in the chest' by offering some alternatives for example if the circuit actually needs a 38 ft, 20 MW SAG mill, you now have the option of a 38 ft gear driven mill. At this size gearless drive is a viable option, but it is significantly more expensive and therefore can pose a challenge.
The SAG mill power draw model of Austin (using the calibration by Doll, 2013) is used to predict the process power draw at the mill shell, Pshell, and the efficiency losses for the drive's mechanical components based on Doll (2012) are used to determine the motor output power, P. The effect of varying the mill speed as a fraction of the critical

Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

In 1989, within the framework of the conference on SAG milling, Barratt presented another formula for SEC required for WAM comminution of minerals from F 80 to the size T 80 [9]: E WAM = (6) where T 80 is the size of 80% content of ball mill feed in WAM — CDBM circuit (typically μm); GDRM means grate discharge rod mill.
