The use of compressive crushing equipment such as gyratory crushers within minerals processing plants can potentially generate large quantities of dust. Remedies to this problem include the retrofitting of shrouds, enclosures, local exhaust ventilation (LEV) systems and water suppression systems. The single or combined application of these systems must be optimised to ensure they operate

Crushing strength (FN) Minimum crushing strength values for pipes or pipe sections are specified in two ways (BS EN 295-1 2.9). For 100 and 150 mm diameter pipes specific values are given of 22, 28, 34 and 40 kN/m, with higher strengths permitted in steps of 6 kN/m. For larger pipes, crushing strengths are given

Our design entailed an underground crushing chamber with dual ore passes and an associated material handling system. At the top, heavy duty grizzlies and rock breaker arrangements accept the run-of-mine ore from production operations, while discharge chutes at the bottom—complete with Ross Feeders—supply the main vibrating grizzly feeder.

Presently, belt life is considered to be unlimited, with minimal, largely routine, maintenance. Crushing and conveying cost is presently $. 15/ton ($ 1. 93/ton/total mining cost) as compared to $ 24/ton haulage cost alone prior to 1968. Feeder-breakers run untended, although a mechanic visits each one twice per shift.

In a safe design all these sources of stresses and strains should be considered. Therefore engineers should consider all factors which affect all parts of a buried system including restrained, unrestrained, underground and aboveground parts. Depending of virtual anchor locations, a buried pipe may or may not include a restrained part.
