1) ball mill is an efficient tool for grinding many materials into fine powder; 2) the ball mill is used to grind many kinds of mine and other materials, or to select the mine; 3) ball mill is widely used in building material, and chemical industry.
the mill is designed to process pebbles and clay material and to reduce sea shells. once the ocean-bed material is milled, the product is screened and the fine material, which includes crushed
with increasing need for fine and ultrafine grinding, stirred media mills became an alternative for conventional ball mills. in this study, samples of bauxite whose chemical composition and hardgrove index values are known were ground to micronized size by a laboratory scale stirred media mill and its performance was compared with a laboratory scale ball (bond) mill. stirred media mill decreased bauxite d 50 size from 780 to 5 µm in 3 min. but, the ball mill
according to different discharging methods, ball mills fall into grate ball mill and overflow ball mill. and our product is the grate ball. this series of ball mill is widely suitabie for ore dressing, chemical, coal, cement and tetractory sectors to operate fine grinding. contact person:cassie ai tel: 0086-371-67996871 0086-371-67996872 e-mail: [email protected] web: http://www.china-xingbang.com/ the other xbm ball mill web:iron ore ball mill gold ore ball mill ball mill
ball mill features. 1) is an efficient tool for grinding many materials into fine powder. 2) the ball mill is used to grind many kinds of mine and other materials, or to select the mine 3) ball mill is widely used in building material, and chemical industry. 4) there are two ways of grinding: the dry way and the wet way.

the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and the working diameter is only 4’8″ with the
the solution about the noise of ball mill. 1.acoustic enclosure (soundproof hood) use the acoustic enclosure to cover the whole ball mill, and then add a sound absorbing device in the hood to eliminate the reverberation noise. this method usually gains the noise reduction of 25-45db (a), but it does not effectively isolate the ball mill transmitting to the outside.
