Ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, and ball mill also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
It is for the mine waste and many industrial wastes, it is a very important crushing way, which has been widely used in solid waste treatment and utilization.
Mill type, structure and working principle
(1) according to the type of operating characteristics, mill can be divided into wet mill and dry mill; by nesting overflow discharge mill can be divided into grid nesting mill and mill around the nesting mill; by loading grinding media of different shapes mill can be divided into ball mill, rod mill, pebble mill and white mill.
(2) ball mill working principle
Ball mill circular cylinder, the use of hollow bolts and the journal's cover band as a single entity, with the cover on the simplified hollow shaft supported on bearings. Simplified internal grinding media, usually steel balls, steel section, steel bars, gravel and ceramics with the gear motor, mounted in the cylinder through one end of the gear driven rotary cylinder. Material from the feeder by feeding end of the hollow tube body when the Simplified journal anyone to turn, and taken to a certain height, because the medium itself suffered gravity, resulting in free fall or dropping, the materials have an impact At the same time there are sliding and rolling medium is in between the grinding material by stripping the role of such a continuous strip mill and the impact of the material crushed. Grated material discharged from the discharge end of the machine.
Popular Ore Beneficiation Plant and Processing
The most popular mineral beneficiation plant manufactured by Hongxing machinery are: gold processing plant, iron ore beneficiation plant, bauxite benefication plant, copper dressing plant, gypsum grinding mill, fledspar crushing plant, mica grinidng mill, barite grinding plant, bentonite grinding plant, coal crushing plant, dolomite beneficiation plant, granite crushing plant, graphite grinding plant, kaolin clay grinding plant, lead ore dressing plant, nickel processing plant, talc grinding plant and so on.
Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes. The most common mineral beneficiation processes include: sample preparation, comminution, size classification, and concentration.
We are the pioneers engaged in the construction of mineral processing plants in China. Our company has built most of the major mineral beneficiation plants in the country. Our mineral processing plants also have been exported to many other countries.
Separating metal ore (such as: gold, iron, chrome,tungsten,etc) from rock ore is a multi-step process that involves crushing the rock ore,grinding and fractionation and concentrating and gathering the metal.
When the mineral after the crushing , grinding, cleaning and fractionation processes, with the help of mechanical force, the subsequent magnetic separator will separate the magnetic substance from the mixture according to their different specific susceptibility.
Then the initial gross separation ore particles will be transported to the flotation machine. Some special chemicals will be added to the liquid according to different ores chemical characters. In this way, the expected metal ore is separated from other substances. But the moisture is quite high, so the expected metal ore need to be concentrated by the thickener. Finally we can use dryers dry the ore and get the high purity and dry expecting metal ore.
