We will begin with the mill's bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills, Rod Mills and SAG Mills.
Coarse particles are held by the rods in the grinding machine for a longer time and thus are subjected to more grinding action. The rod mill process has a great selective grinding effect. The particle size of the grinding product is uniform, and the degree of overcrushing of the ore is light, so the rod mill can form a single-stage rod …

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods.
Phosphate GRINDING. Wet rod mill grinding to approximately 35-mesh is employed as only a moderate degree of grinding is required and the production of slimes must be minimized to effect maximum recovery. The Rod Mill operating in closed circuit with a Cyclone Classifier is effective in accomplishing the liberation of the phosphate …
grinding mills. Our rod mills have been manu-factured since 1925. Applications The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/ coke, and other materials for both wet and dry p- a plications. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained

The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
The three main mill options for phosphate ore are: l Ring-roller mills: Vertical rollers rotate inside a fixed horizontal ring (Figure 1). Material fed between the rollers and the ring is ground to powder. l Ball mills: A horizontal rotating cylinder contains a charge of steel balls. These balls tumble as the mill turns so that
There are several pieces of equipment that can be used for grinding phosphate rock into a fine powder, including: Ball Mills: Ball mills are large cylindrical vessels that are filled with grinding media, such as steel balls or rods.The rock is fed into the mill, and as the mill rotates, the grinding media grinds the rock into a fine powder.
plant for future use. The rock is slurried in water and wet-ground in ball mills or rod mills at the chemical plant. Consequently, there is no significant emission potential from wet grinding. The small amount of rock that is dried in Florida is dried in direct-fired dryers at about 120°C (250°F), where the
Rod mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on, which runs steadily and efficiently. Rod mills are an efficient crushing machine for grinding various materials into powder.
