Product contamination from media and lining wear is virtually eliminated.May 08, 2020 During the grinding process, the steel rods in the rod mill are in line contact, while the steel balls in the ball grinding mill are in point contact. Ball mill VS rod mill output size of material. The output size of the grinding material in the ball grinding mill is generally between 0.047mm 0.4mm, and that of the rod mill is between 0.833mm 0.
Grinding Particle Size. Due to the relatively high operating costs in grinding stage, most plants often use ball mills for grinding operations after fine crushing. The particle size of the ground material is relatively fine, the feeding particle size is usually in the range of 10 20mm, and the product particle size is usually in the range of 0.The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Jet Mills. A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size.The Mikro Pulverizer Hammer Screen Mill is a high speed mechanical impact mill designed for continuous size reduction down to D90 45 μm. The Mikro UMP Universal Milling System is a compact, high speed impact mill capable of coarse granulation or fine size reduction with interchangeable rotor configurations.
