What Are the Differences between Dry and Wet
The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that 2.1.2 Ore Blend Grinding at HPGR and Ball Mill.

Simulation of wet ball milling of iron ore at Carajas, Brazil
The tests were made in a steel cylindrical ball mill of 250 mm internal diameter (D T) and 250 mm length (L T) fitted with eight symmetrically located horizontal lifters (see Table 1) and smooth end walls, with one end wall removable and locked in place with a quick release locking clamp.The media were stainless steel ball bearings of 25.4 Companhia Vale do Rio Doce (CVRD) is a world leader in production of iron ore, from its deposits in Brazil. It registered a profit of about $5 billion during 2005, more than a 60% increase from 2004, from sales of $16 billion. This resulted from increased prices of iron ore products, 71.5% higher for lump ore and 86% for pellets, plus Simulation of wet ball milling of iron ore at Carajas, Brazil

Ball mill
Ball mills are used for grinding materials such as mining ores, coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed. Ball mills are used often in scientific work to reduce the particle size,eliminate agglomeration, change the shape of particles, provide for mechanical alloying,mixing, All abrasive ores, abrasive materials, various stone materials, and some metals can be ground by a ball mill. Common grinding materials for ball mills: 1) metallic ores such as gold ore, copper ore, iron ore, chromium ore, fluorite ore, phosphorite, etc. 2) chemical raw materials: quartz sand, feldspar, limestone, marble, zircon sand, cement clinker, slag, etc.Ball Mill Wet Ball Mill & Dry Ball Mill HXJQ Mining Machinery

Optimization of Solids Concentration in Iron Ore Ball Milling
Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to Ball mill grinders are commonly used for grinding a variety of ores like copper ore, gold ore, iron ore, lead-zinc ore, nickel ore, manganese ore, chrome ore, lithium ore, etc. The role of the ball mill in ore processing is to reduce the size of the ore particles so that valuable minerals can be extracted more efficiently.ball mill-Wet ball mill or Dry Grinding ball mill
