underground crushing system design

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.

underground crushing system design Bussa Machinery

Although design calculations may indicate overcapacity, no conveyor in any crushing plant should be less than 0.5 meters wide and, in actuality, it is best to standardize on a minimum belt width of 0.67 meters throughout the crushing system. Design should be such that conveyor troughing and return idlers can be lubricated from one side. Read More

Underground Crusher Selection and Design Crushing

2021-5-19  Typically in underground operations the crusher feed is not coarse and lumpy as in an open pit and is usually passed over a grizzly before crushing. It would take some special circumstances to justify the additional excavation required, additional equipment cost and more difficult maintenance.

2019-5-7  The heart of this system is a 42-inch gyratory crusher on the 2475-foot level. The manufacturer agreed to split the top shell, making it possible to lower such a large crusher down No. 1 shaft. This is fed by a 72-inch wide by 20-foot long reciprocating feeder which empties the ore pass system from the four Swedish-style dumps above.

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

Design of rock support system under rockburst condition

2012-9-25  Although some model-based design and numerical methods are used, rock support system design for underground excavations is largely dependent on empirical methods and practical experience. Whatever design method is applied, a final design is best arrived at based on an observation design method. This is particularly the case for bursting
