CalculateTopBallSize ofGrinding Media-FRED C. BOND Equation & Method Previous Next Although it was developed nearly 50 years ago, Bond ‘s method is still useful for calculating necessarymillsizes and power consumption forballand rodmills.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure, high efficiency, easy adjustment and economy.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
First you need the volumetric capacity of themill, this is the volume of themillat rest where the ore just reaches the discharge level (often about 1/3 of the internal volume). From this you need to subtract the volume of thegrinding media. You now have the unit capacity. Then take the volumetric feed rate of the new ore per time.
Ball Mill Power CalculationExample #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of80% passing ¼ inch(6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows:
D1, D2, D3, etc. = diameter ofballsat end of first, second, third, etc., intervals.Wt= totalweightofballsin themill, W’t = totalweightofballsin any interval. w =weightof anyball. R = rate ofball wear. Rt = loss inweightof themill chargein time T. It is equal to π/6Dm³ SNw.

Jul 01, 2003· Figure 3 depicts the effects ofmediasize ongrindingtimes. From this plot, it is shown that a target fineness of 80% 2 microns is normally achieved in 315 minutes of recirculationmillingwith 1.0 to 1.4 mmgrinding media. By reducing themediadiameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
