Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill
Typical specific energy consumption is 30 kWh/t in grinding of cement. Barmactype crushers found application as a pregrinder in cement grinding circuits operating with ball mills to reduce the specific energy consumption of ball millgrinding stage .
Mar 08, 2013· calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.
Ball Mills are widely used in the ceramic and mining industries, where the grinding process requires strict grain size control. WEG developed an efficient solution for this application, providing a reduction in electric energy consumption of up to 35%.
Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pregrinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation ...
Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

Energy saving ball mill is the improved grinding equipment for mineral materials secondary grinding after crushing. The structure of original ball mill is changed, machine body and chassis are an integral whole. Therefore, it can be placed on basic plane once when installation.
This machine is a horizontal cylindrical rotating device, external gear transmission, two warehouses, lattice ball mill. The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material.
In the early time of a dressing plant in Xinjiang, it adopted ordinary ball mill in grinding system, due to the lining board, the grinding caused discharge chunk and abnormal breakage of lining board, which led to the ball mill cannot operate normally. To solve this problem, the client selected Xinhai energy saving ball mill.
Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the [.]
The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.
Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ballmill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 030% pebbles, by volume, with savings in energy and ball consumption increasing progressively.
Further, Attritor tanks are all jacketed which allows for more precise temperature control during high energy ball milling. The savings in energy and the increase in grinding efficiency provided by Attritors are substantial. The graph below compares various mills during the high energy ball milling process.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different ...
The greatest challenge when developing a high energy ball mill is keeping the temperature under control as the enormous size reduction energy leads to considerable heat builtup inside the grinding jar. RETSCH solved this problem with an innovative integrated water cooling system.
