grinding and crushing (Dean, 1995). Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.)

crusher with circular jaws, between which material is being crushed at some point all the time. A conical crushing head gyrates inside a funnel shaped casing open at the top. A crushing head is pivoted at the top. An eccentric drives the bottom end of the shaft. The bottom of the crushing head move towards and away from the wall.

Open Circuit Crushing. In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables. These variables are anything that affect the performance of the equipment. Lets begin with an over view of these two crushing stages.

GRINDING Abrasive machining: •The oldest machining process - "abrasive shaping"at the beginning of "Stone Era". •Free sand was applied between two moving parts to remove material and shape the stone parts. Grinding: •Removing of metal by a rotating abrasive wheel.(Very high speed, Shallow

Treatment of lead and zinc ores begins with milling. Milling is a multi-stage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill.

The first one comprises several steps: crushing and grinding operations oriented to liberate gold particles so that they can be leached. The comminution product must be 80-90% passing 75 µm. Normally, the processes is employed when the gold content is ranging from 5 to 15 g/t.
