balance ball charge grinding mill example calculations Ball Mill Power Calculation Example#1. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing #188; inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed
determine mass balance of a ball mill grinding circuit. Remote and Distributed Expert Control in Grinding Plants Authors: Lynn B. Hales and Michael L. Hales, KnowledgeScape time it was believed that the energy efficiency of ball mill grinding was as low as 3 to 5 Mathematically this concept of the grinding process was represented in a mass balance

Jul 01, 2016#0183;#32;Using a population balance approach, and assuming that the ball wear is linear, Austin and Klimpel derived an equation that predicts the equilibrium ball size distribution as follows: (28) m k = d k u 4d k l 4 d max 4d min 4 where d max and d min are the largest and the smallest ball sizes remaining in the mill, respectively.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is

permits plant metallurgists to determine which unit operations (hydrocyclone or grinding mill) require optimization. A ball mill circuit survey is required to generate a mass balance and where the percent solids and particle size determinations are made for each of the following streams: hydrocyclone overflow (circuit product);
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
