difference between crushing and grinding. it consequently follows that the crushing of a quantity q of ore, consisting of particles of uniform size that will just pass through a screen of m meshes per lineal inch down to another uniform size, such that they will just pass through a screen of n meshes per lineal inch,
crushing and grinding are processes that work together to get the rock to be small enough so it can go to flotation. in flotation, they objective is to separate the valuable ore from the waste rock. crushing is the initial stage of comminution the action of reducing a material in mineral processing.
leadbearing ore is mined from underground or open pit mines. after extraction, the ore is processed by crushing, screening, and milling. domestic lead mine production for 1991 totaled 480,000 megagrams mg 530,000 tons of lead in ore concentrates, a decrease of some 15,000 mg 16,500 tons from 1990 production. except for mines in missouri, lead ore is closely interrelated with zinc and silver.

the ore is conveyed, and lime is added 2 to raise the ph of the ore. following crushing through a jaw crusher 3 , the ore is fed into the semi autogenous grinding sag mill 4 along with water and steel balls. the grinding process reduces the rock to a slurry. the sag mill is a large revolving cylinder.
ore crushing and grinding ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. there is a balance to keep proper ore size neither too rough insufficient liberalization and too fine over-crushed in order to achieve high recovery rate and high efficiency.
step -i crushing and grinding ball mil stamp mill ball mill a ba mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics etc. a ball mill consists of a hollow cylindrical shell rotating about its axis.
in all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment.
