smaller sizes. Depending upon the feed and product particle size, the crushing operation can be classified as follows: 1. Primary crushing: The feed material is usually the run of mine. 2. Intermediate crushing or secondary crushing: The feed material is usually product of a jaw crusher. 3. Fine crushing or coarse grinding:
Choked crushing is encouraged to some extent, but if this is not serious, the rock-to-rock crushing produced in the primaries reduces the rock-to-steel crushing required in the secondaries, thus …

Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.

zA rock consists of minerals and chemical compounds. There are at least 2500 different minerals, each with its own composition and in ternal structure. A rock often consists of at least two minerals. This explains why one kind of rock can exhibit such differing characteristics. Even so, just a few minerals make up the major constituents of the most
