Nowadays, ball grinding mill is so popular and can be choose to the best seller milling equipment. Why ball grinding mill received so much praise? The reason is mainly due to its stable performance, high efficiency and economical. Hongxing ball grinding mill is so popular among consumers, and it has a large market both in aboard and at home. The market for ball grinding mill is so prospect in future. The user feedback information indicates that ball grinding mill adopts the wear resistant grooved liner can improve grinding efficiency, and has a obvious energy saving effect. ball grinding mill wear resistant grooved liners are self-developed with independent intellectual property rights, and has simple and reasonable structure, can greatly improve the grinding efficiency of the ball grinding mill, also the rate of power saving is obvious. The technology is the domestic leading and an initiative domestically, has reached the level of similar foreign products. The rod mill comprises a cylindrical shell, lined with replaceable liner plates, which rotates upon a horizontal axis. The mill contains a mass of hardened steel rods up to 100 mm in diameter as media which occupies approximately 40% of the volume. The mill is supported at each end by hollow, cylindrical bearings, the trunnions, and driven by a peripheral ring gear. The feed material enters the mill through one or both of the trunnions and is discharged through ports in the shell, either end-peripheral discharge or centre peripheral discharge if fed through both trunnions. The mill is operated wet in the vast majority of mineral processing plants i.e. a solid to water ratio of about 2:1 on a weight basis. Within the aggregate industry, however, the material may be dry or moist. The rotation of the mill causes the rod charge to tumble and cascade producing comminuting by a combination of compression and impact. The action of the rods is favorable to the production of 'fine' aggregate since the larger particles holding the rods apart are crushed preferentially and a minimum quantity of very finely sized particles is generated by abrasion and attrition. Nevertheless, the rod mill suffers serious disadvantages when compared to fine crushers; notably lower efficiency of energy utilization and the costly replacement of worn rods.   ball mill machine: http://www.crushing-mill.com/impact-crusher/6.html
