Get PriceA grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. As the feed size is reduced further, less of the 50.8 mm balls and more of the 25.4 mm balls are required for the maximum capacity, attaining of 25.4 mm balls
Get PriceThe SAG mill product is then crushed to passing 3.35 mm and is subjected to the Bond ball mill work index (Sd-BWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability
Get PriceMar 19, 2017 Do you need a quick estimation of a ball mill's capacity or a simple method to estimate how much can a ball mill of a given size (diameter/lenght) grind for tonnage a product P80 size? Use these 2 tables to get you close. No BWi Bond Work Index required here BUT be aware it is only a crude approximation
Get PriceThe material is ground at a specific speed for a specific period using a specific quantity of grinding steel balls. The size range of balls provided to support the tests is from 12.5 to 40 mm. The size of ball varies with the requirement of the tests and complied standard. The laboratory ball mill capacity also varies according to the
Get Pricehas recently developed a 4500 HP (3352kW) Vertimill®, designated the VTM-4500-C. It will begin operation in 2015 in a primary grinding capacity. Vertimills® are globally recognized as energy efficient grinding machines and have been proven to grind more efficiently than ball mills with feeds as coarse as 6 mm to
Get PriceThe mill operates continuously in a various flow diagrams (open or closed cycle) with central material discharge and enables to give out homogeneous (in fineness) ground product by means of grinding bodies (balls and cylpebs). Ball mill grinding capacity depends on characteristics of the milling material ( hardness,
Get PriceA cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Contents. [hide]. 1 History; 2 Materials ground; 3 Temperature control; 4 Ball
Get PriceDec 19, 2017 The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large

Get PriceAbstract- In this study, a 5 kg laboratory ball mill has been designed, constructed, and its performance analysed. This was achieved by using Bond's equation to calculate the specific and shaft powers required to drive the mill at the specified capacity, and also to size the mill. After the fabriion of the ball mill, grinding test
