Rod mill is also called rod grinding rod mill, bar mill and rod grinding mill. Our rod grinder is especially suitable for crushing river gravel to make sand. Its a kind of effective and energy saving rod grinding machine. Moreover, according to different materials and discharging methods, there are dry rod mills and wet type rod mills for choice.
Fine crushing and rod grinding have been investigated using a laboratory-scale jaw crusher and a rod mill. The net energy consumption in both crushing and grinding was evaluated from torque measurements. An empirical relationship was established between energy consumption, particle size and operating parameters. When the mill feed size is reduced, through fine crushing, to about 80
Jun 03, 2020 Unlike rod or ball mills, high pressure grinding rolls reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other. There are no rods or balls that need replacing and it reduces energy consumption by about 40 percent for certain ore ...
When particle size is required to be within 2.0-0.5 mm, we generally use rod grinding machine whose maximum product size is smaller than 4.7 mm and minimum size not less than 0.4 mm.. Brief introduction to Hongxing rod mill. Rod mill can be pided into dry rod mill and wet rod mill, so users can choose proper rod mill according to their own actual situations.
