The transmission machinery of Energy-saving overflow ball mill substitutes large-scale double row self-aligning roller bearing for sliding bearing, so it is easy to start and saves energy by 20-30%.
Energy-saving overflow ball mill adopts groove-type circular lining plate that is instrumental in increasing contact areas of iron balls and ores, which enhances grinding action and ore lifting capacity and decreases energy consumption.
Overflow ball mill working principle:
This ball mill is horizontal type and tubular running device, has two warehouses. This ball mill is grid type and runs along the outside gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.
In this warehouse, there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard. When the barrel body rotates ball mill produces centrifugal force, at the same time, the steel ball is carried to some height and falls to make the material grinding and striking.
After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the end products are completed.

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of coarse material and minimizes production of slimes.
Of the three main types of rod mill, overflow, end peripheral discharge, and center peripheral discharge only the overflow mill is in common usage. Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. 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.
Ball Mill Process
It is necessary for a tech staff to perform a variety of service options for manufacturers of large mining equipment. The ball mill is no exception. Due to the precise grinding power of the ball mill, these machines are used by some manufacturers to process and produce black powder, but without the pyrotechnic capability due to the enormous impact these machines incur in processing. The machinery parts and components can be quite expensive, enabling them to grind tiny particles into fine powder. Cold welding, and mechanical alloy processing are often the primary goals of ball mill machinery. The ball mill can be used in the processing of wet or dry materials, as well as contaminated or safe chemical materials. The variety of materials presents a spectrum of functionality on which the ball mill must be able to operate. Professionals should be proficient in their maintenance skills when working on these types of machinery.
Ball Mill Maintenance
Density of material to be processed, hardness of media or other materials, and chemical composition are considerations for the capabilities of the machinery, as well as their routine maintenance needs. If the ball mill is regularly used to process extremely dense or dangerous materials, frequent maintenance and even modification for optimal use should be applied to the machinery to ensure that production is running at its most desired capacity. Pressure and speed should be regulated and checked periodically to ensure that grinding is taking place at the best rate, speed, and production output possible.
Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc. In our company, this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%. According to different discharging ways, it can be divided into two kinds, grate type and overflow type.
