Zenith has produced the ball mill machine for the worldwide customers, such as in England, India, Indonesia, South Africa and so on. Typical examples are the various ores, minerals, limestone, etc.Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.
The extract the metal through ores, several physical and chemical methods are employed.The majority of the iron ore that is mined can be used for making steel. So we need the extraction of the pure metal from its ore. The method used depending on chemical properties and nature from the ore from which it will be extracted.
Considering the fact that the separated ore are wet, they should be dewatered by thickener initially, and dried by dryer. The classified ore will get into magnetic separator. When it gets the affordable fineness, it's transported into ball mill by elevating conveyor and feeder, and it is milled by ball mill. There's a concept that in the event the weights of sound particles are unique, the sedimentations shall be diverse, as well as the mixed ore may be classified by screw classifier. The subtle milled ore will get the following process: classification. Due to the fact the unique magnetization coefficients of ores are various, the magnetic substance of mixed ore is separated from other people with magnetic and mechanical force.The certain mineral processing flow is as follows: The extracted ore should be crushed by jaw crusher at first. The mineral matter, that has been separated by magnetic separator initially, is transported into flotation machine by conveyor, and distinctive medicines are added in accordance with unique traits of ore, in order that the necessary ore is separated from other people.
, Ltd, India. It is also typical to employ a backing compound at a region around the spacer ring for additional structural reinforcement and to ensure the various components mated together correctly. Example backing compounds include Korrobond 65™ and 90™ are available from ITW (‘Korroflex’) Ltd, Birkshaw UK; and KrushMore™ from Monach Industrial Products (I) Pvt. In particular, it is common to use backing compounds to structurally reinforce the outer shell and assist with contact between the radially outward facing surface of the outer shell and the radially inward facing surface of the topshell.Typically, both the inner and outer crushing shells wear and distort due to the significant pressures and impact loading forces they transmit.
SUMMARY OF THE INVENTION.The purpose of the invention is to present a new type and more accurate manner of defining the size of the ball charge of a grinding mill without stopping the grinding mill .
At first dry type magnetic separation being carried out in above-mentioned aeolian accumulation sand plain ore deposit, desert separates; Dry type magnetic separation separates and comprises twice separation operation in front and back; The dry type magnetic separation separating step is in a rare earth permanent magnet roll-type dry high-magnetic separation machine, to carry out; The magneticstrength on the magnetic roller surface of this rare earth permanent magnet roll-type dry high-magnetic separation machine is 13000 Gausses, and the separating effect after dry type magnetic separation separates is as shown in table 4 below.
