· Wet grinding. Wet grinding is suitable for most materials, such as all kinds of metal ore, nonmetallic ore. As long as it is waterrepellent and will not affect the quality of the finished product, the material can be used for wet grinding. Common ore includes copper ore, iron ore, molybdenum ore, phosphate rock, feldspar mine, fluorite ore, etc.
Dry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero ...
Feb 01, 2012 · grinding process In most industries, size reduction could be divided into main egories: crushing and grinding. Grinding, also called fine milling or pulverising, is the process of reducing materials to fine powder or very fine particle size. Grinding process is different from crushing, which reduce the big massive materials to a rock, pebble or grain size..
· The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure .For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.
