Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
The ball mill is the most important equipment in the beneficiation equipment, and the structure is reasonable and price concessions. Dry grinding and wet grinding are all possible, and the fineness is about 800 mesh, which can be adjusted.
Good working conditions can strengthen the grinding outcomes of overflow type ball mills. Therefore, in practical operation, workers need to continuously adjust overflow type ball mills working conditions so that they can work at optimal state. Then, what are the working conditions influencing the overflow ball mills .

In 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 materials for subsequent treatment.
The amount of feed was set at 1175 g, which was proportional to industrial scale. The ball mill speed was constantly set at % Cs. Experiments were conducted at different ball sizes (between 20 and 40 mm), grinding time (10–30 min), solids content (65–80%) and work index of copper sulphide ore .
Application of Ball Mill. SBM ball mill has has two ways of grinding: dry process and wet process and is a very efficient grinding mill for powder,SBM ball mill is widely applied in the cement, the silicate product, new type building material,fireproof material, chemical fertilizer, black and nonferrous metal, glass,ceramics and etc.
May 10, 2019· By the way, the larger the diameter of the ball mill, the lower the filling rate. For the rod mill, the filling rate is generally 10% lower than that of the ball mill of the same specification. Diameter of steel grinding ball. The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore.
