Diamond reserves and production of South Africa are in the front rank of the world. Large-scale development and utilization of diamonds result in production of a large number of diamond wastes. Resource utilization of diamond waste can turn waste into treView Details
The crude ore is crushed to a maximum size of 9 in and screened into 3 sizes The primary mill is 5½ ft in diameter The length can be varied from 2 ft to 5 ft in 4 andor 11 in increments The secondary grinding circuit uses a 3 ft diameter by 5 ft long pebble or ball millView Details
Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclonesView Details
The efficiency of the mill to break ore is a function of both the feed size distribution and the relative hardness of the ore When the feed size of a SAG mill becomes coarser ie α r increasesView Details
Apr 07 2020 · Blasted ore from the open pit that is directed to the mill undergoes primary secondary and tertiary crushing to reduce the ore size increasing the surface area to facilitate the release of minerals The crushed ore is fed to the concentrator where it is mixed with water in mills to achieve further size reductionView Details
The measured BW i was 140 and 66 kWht for the mediumhard and soft ore respectively at a closing screen size of 106 μm compared with the simulated values of 132 and 56 kWht The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions onView Details
Rod mills oper ate typically at 3cbetween 064 and 075 with larger diameter mills running at the lower end and smaller mills at the upper end Typical rod loads are 35 to 45 of mill volume and rod bulk densities range from about 5400 kgm3to 6400 kgm3 Rowlands CA and Kjos DMView Details
inside the mill such as increased load liner shape mill speed or friction that causes the cascading ore and steel in this case 10 steel was used to hit the shell more than 30o before the vertical diameter will cause reduced throughput See Figure 2 and equation 1 below MuchView Details
specified as 2 and Cyclone 2 particle size is 30 300 µm the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15 300 µm If the hardness of the ore increases the particle size in the mill discharge from ball mill 1 will increase With the same water addition to sump 1 the particle size of Cyclone 1View Details
