Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones

Feb 13, 2017 Feb 13, 2017 These ball mills are relatively small, bearing mounted on a steel frame. All ball mills are sold with motor, gears, steel liners and optional grinding media charge/load. Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry

Strong magnetic iron ore separation process. It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding. At present the fine grinding technology promoted by Xinhai improves the concentrate grate from 61% to 67%

Basic Process of raw ore beneficiation and upgrading plant 1) The ore is first sent to the jaw crusher for primary crushing. 2) Then the ore with a proper size for secondary crushing fine crusher, or cone crusher to get the 25mm site, then through betlt conveyor will

Ore ball mill sometimes called ore grinding mill, is generally used in mineral processing concentrator, processing materials include iron ore, copper ore, gold ore, molybdenum ore and all kinds of nonferrous metal ore.The core function of the ore ball mill is to grind the materials, and also to separate and screen different mineral materials, and to separate the tailings, which is very

The ball mill is the key equipment for further crushing after materials are crushed in ore separating line. It is one of the widely used high-fineness machines, which fall into many types, such as the energy saving ball mill, the horizontal ball mill, the ceramics ball mill, the cone ball mill, the rod mill, etc

Ores with qualified size in the powder ore bin were transported to the belt conveyor by vibrating feeder. Ores were sent to the grid ball mill by the belt conveyor for grinding, and products were sent to linear vibrating screen for screening. The large particles left on the

The magnetic separation line is composed of stock bin, feeder, crusher, ball mill, classifier, magnetic separator and other equipment. The main role of belt conveyor is to connect to each equipment. Magnetic separation equipment is the most widely used corollary equipment with the most mature technology in the whole ore processing plant, which

Iron ore magnetic separation plant is composed of vibrating feeder, jaw crusher, cone crusher, circular vibrating screen, ball mill, classifier, magnetic separator, concentrator, filter separator, drying machine and other equipment.This magnetic separation line has such advantages as high efficiency, low energy consumption, high processing capacity, economy and so on
