Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches.
By referring to equipment manufacturers bulletin on crushers, Fig. 1, a crusher producing 80% passing 3/4 requires a close side setting of approximately 5/8. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure is chosen. The 159 indicates a 548 crusher size with 1 eccentric throw.

The coarse grain permanent magnetic roller type strong magnetic separator can obtain a coarse concentrate with an iron grade of 32% 34% and a tailing grade of 10% 12% under the conditions of a feed size of 20 2 mm and a feed grade of 24% 26%. 2. Stagegrinding and stage separation process.
The crusher and screening equipment work together and the grinding and classification equipment form a closed circuit cycle. Selection of Crushing and Grinding Technology back to top. 1.Technological principles of more crushing and less grinding. The concept of more crushing and less grinding is deeply rooted in people39;s minds, but many ...
The crushing equipment adopts coarse crushing type iron ore jaw crusher and fine crushing jaw crusher to crush iron ore into a particle size suitable for grinding and enter the grinding stage. There are two types of commonly used powder grinding equipment: ball mill and Raymond mill.
