Preliminary design of underground crushing chamber

This paper explains how a large Underground Crushing Chamber of 140m 2 of section and 35m length has been preliminary designed and optimized by applying a combination of two geotechnical well-kwon software: A 3-dimensional boundary element stress analysis as EXAMINE 3D and finite element modeling program as PHASES 2D. The first one allows us to know the correlation among the main

Efemçukuru Mine Underground Crushing Station

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. The vibrating grizzly feeder was designed to

Installation and Effect of an Underground Crushing and

The dimensions of the crushing station were determined at 20 feet wide by 27 feet 9 inches high by 102 feet long. In order to excavate the station, one end was slotted and the width was entirely overcut to permit excavation by longhole drilling. Blasting was done with AN/FO. Fragmentation was good and overbreak was minimal, requiring only routine scaling and bolting to secure the walls. The chamber in the floor of the crushing

Common Feed arrangement problems — Sandvik Mining

Description: Segregation is when coarse and fine particles enter different parts of the chamber. Typically, smaller particles will accumulate at the bottom of the conveyor and large particles on the top. When fed into the crushing chamber the large particles accumulate on one side of the feed hopper and the small particles on the other side. Also, segregation will occur when material is transferred from one

01/03/2021· The crushing complex is serviced by the section of underground conveyor transport No. 18 of the underground mine. “The capacity of the crushing complex is 560-600 thousand tons ore per hour. The annual capacity of DK-13 is about 1.238 million tons of ore. The commissioning of one more crushing complex also makes it possible to carry out scheduled preventive repairs of bunkers, bypass raises, equipment of other crushing

Crusher an overview ScienceDirect Topics

Medium-sized jaw crusher in operation in underground mine for crushing run-of-mine (ROM) ore before transferring to the surface. The gyratory crusher consists of a long, conical, hard steel crushing element suspended from the top. It rotates and sweeps out in a conical path within the round, hard, fixed crushing chamber (Fig. 13.11). The maximum crushing action is created by closing the gap

Industrial Solutions Gyratory crushers

The feed material that is fed into the crushing chamber from above is progressively crushed between the crushing elements (C), finally exiting the crushing chamber at the bottom (F) under the influence of gravity. The crushing gap is adjusted by hydraulically lifting or lowering the main shaft. This hydraulic shaft adjustment is used mainly when

underground tunnels and caverns, which results in special re-quirements for the crusher design. Both gyratory and jaw crushers have proven themselves in the field of hard rock crushing for decades, but due to their large overall height have the disadvantage of requiring the construction of large-volume and cost-intensive caverns for

iXRS 600 Sizer Komatsu Mining Corp.

Proven crushing technology. The iXRS 600 Sizer utilizes proven Joy crushing technology in a double roll sizer configuration. Spherical roller bearings are installed in a flange-mounted housing outboard of the crushing chamber, protecting the bearings if water is utilized for dust control. It also means shaft removal is not required for bearing replacement.

Microtunneling method statement civil engineering

"To avoid collapse, the ground pressure and ground water pressure are balanced by the pressure of suspension water in the crushing cone due to the difference between feed pressure and slurry suction, which guarantees that the amount of the excavated soil exactly equals the replaced volume by the pipe line. so simply during micro-tunnelling work there is no need of using dewatering in the whole path of
