Get MoreAug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the

Get MoreCapacity. 1-95t/h. Input size. 25mm. Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls

Get MoreHow Ball Mill Ore Feed Size Affects Tonnage Capacity. 26/07/2017 The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns Such feed causes power inefficiency if fed directly to a ball mill Even though the rod mill could

Get MoreMill ball load can be reduced from 35 per cent to 30 per cent according to simulation results. ... the potential to improve the capacity of ball mill circuits by replacing cyclones with screens

Get MoreFor 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, and the radius of the mill, R, i.e

Get MoreBall mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less

Get MoreA ball mill of 1.2 m diameter is being run at N = 50 rpm. What is the size of the balls that we have to employ for proper grinding? (Answer: Size of the ball = 0.7419 m) 12. What is the critical speed in rpm of a ball mill having 1000 mm inner diameter with 75 mm ball diameter ( Answer: N c = 44 rpm) 13. A ball mill of 120 cm diameter is

Get MoreAug 09, 2017 Ball mill as a kind of popular grinding and ore beneficiation equipment is widely used in cement manufacturing, silicate products, construction materials, refractory and other industries. It is

Get MoreApr 22, 2019 There are a lot of problems that most mineral processing plant meet when operating the ball mill, such as low grinding efficiency, low processing capacity, high energy consumption, unstable

Get MoreAdvantages: 1. The rolling bearing is used instead of the sliding bearing, the friction force is greatly reduced, the starting is easy, and the energy saving is remarkable. 2. The use of high-strength and wear-resistant combined hammer head can save materials and reduce waste. 3. The working principle of the ball mill is relatively advanced

Get MoreJul 08, 2016 The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size “pebble” discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed. Where the SAG mill/ball mill circuit is

Get MoreFeb 13, 2017 The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and the working diameter is

Get MoreJul 26, 2017 The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing

Get MoreGenerally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L: D is, usually, accepted in the range 1.56–1.64
