The Determination of the Optimum Loading for Ball Mill. When designing ball mill, it is necessary to choose suitable anti abrasion materials and determine the suitable loading of grinding balls when starting and the refilled loading of grinding balls during the operation, which has significant practical meaning to the reduction of metal consumption and improvement of economic benefits.

The 24 x 39.5 Ball Mill. The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [39.5 feet] long. They are overflow discharge ball mills with inside diameters of 7315 mm [24 feet] and grinding lengths of 11887 mm [39 feet]. Each Ball mill

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 non ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

A wide variety of ball mill prices options are available to you, such as free samples, paid samples. There are 13,341 ball mill prices suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Japan, and Taiwan, which supply 99%, 1%, and 1% of ball mill prices respectively.

Copper Ore Ball Mill Energy Saving Ball MillCone Ball Copper ore mill is the key equipment for second grinding after the copper ore being crushed. Copper mill can be employed to dry or wet grinding of a variety of ores such as copper, lead, zinc and other grind able materials.

Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30 x 41 . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.

Abstract. The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index ( Wi ). This index is determined on a laboratory scale using a Bond ball mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.

Charge Height. Generally For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He,

In the determination of ball mill work index 15 kg of representative ore at 100% + 3.35 mm is crushed to 100% 3.35 mm (Amtech, 2006). The first grinding test is started with an arbitrarily chosen number of mill revolutions. At the end of each grinding cycle, the entire product is discharged from the mill and is screened on a test sieve.

Jun 28, 2017The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder making production line including cement, silicate, new type building material, refractory material, fertilizer, ore dressing of ferrous metal and non ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type.
