  • Rod Mill an overview | ScienceDirect Topics

    Rod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50% solid by mass This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture As such, when the product is sticky, rod mills are preferred over ball millsIn all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals In the chemical and process industries, grinding is an important step in preparing raw materialsBall Mills Mineral Processing & MetallurgyContinuous movement of the pulp through the rod mass eliminates the possibility of short circuiting any material The discharge end of the Rod Mill is virtually open and larger in diameter than the feed end, providing a steep gradient of material flow through the millRod Mills Mineral Processing & Metallurgy

  • Grinding Mill Design & Ball Mill Manufacturer

    These mills are of a special design and described on special request by all Ball Mill Manufacturers Types of Grinding Mill Manufactured The different types of grinding mills are based on the different types of tumbling media that can be used: steel rods (rod mills), steel balls (ball mills), and rock material (autogenous mills, pebble mills)In dry grinding, material is transported through the mill by mediumhigh velocity air that is injected at the inlet or mill feed end As the mill rotates, mineral critical size fines are brought to the ball charge surface and are suspended and liberated by the injected airMaterial Movement Inside a Ball Mill bulkonline Forums(9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass The rod mill discharge is pumped, without any further water addition, to the first ball mill The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1) See Figure 1 for a schematic of the process flowGrinding control strategy on the conventional milling

    Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced Various classifiers, such as screens, spiralBall Mills, Pebble Mills, Material Processing Mills: For more than a century, Patterson has been the industry leading manufacturer of wet and dry grinding mills for size reduction or dispersal Patterson’s ball, pebble and rod mills are built to last We are still filling parts requests for mills sold over 60 years ago Patterson mills are available in a wide variety of standard sizes andBall Mills, Pebble Mills, Material Processing MillsFigure121: Flow sheet showing flow of materials Solution: material balance cyclone feed CF Ball mill feed B Rod mill feed R CF B 25 (1) Performing balance on 250 µm size CF 14 5B 25 27 (2) Solving equation 1 and 2 we get CF 611 tons/hr Volumetric flow rate of feed (dry) to cyclone 2036 Ans (PDF) Lecture 12: Exercise on mineral processing Contents
