Besides, the diameter of the hollow shaft at both ends of the barrel of the sag mill is large and the length is short.The diameter is large for its large feeding size.Generally, the inner diameter of the hollow shaft is about 2 times of the larger ore feeding size, which is about 0.2-0.3 times of the inner diameter of the ball mill.The short length is for the higher speed of the flow of ore.

As the significant part of ore-dressing equipments, the ball mill plays a much important role in beneficiation.
Take the 2500tpd new type dry technique cement production line for example.Comparing the 4.610 raw material mill + 3.5m dry grinding production system with xpcf crusher + 2.2m raw material mill or 2.4m ball mill system, the former system needs 7.16 kwh for each ton raw material.If per kwh is 0.6 yuan, the cost for per raw material will increase 4.296 yuan.So for each to process raw material 4000 tons, the production cost increases 17200 yuan.In one year, the cost will increase about 5.495 million yuan.
The taurus has several available configurations depending on the application and mill size.Netzsch ecutec also carries an extensive selection of special grinding media to optimize the performance of the ball mill specific to the customer's requirements.Together with netzsch ecutec classifiers, the taurus provides a wide range of fineness with top cuts down to d98 < 2 m and up to d98 300 m.Due to high manufacturing quality, a long life-time and a low maintenance are guaranteed.This machine is the solution for fine to ultra-fine processing of a wide variety of materials.
Energy-saving rod millis generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.Ball mill is an efficient tool for grinding many materials into fine powder.The ball mill is used to grind many kinds of mine and other materials, or to select the mine.It is widely used in building material, chemical industry, etc.There are two ways of grinding: the dry process and the wet process.It can be divided into tabular type and flowing type according to different forms of discharging material.
