A new design which will increase capacity to 35 t/hr is required. 1.3 Aim The project aims to design a system that will increase the crushing rate and improves the crushing efficiency of gold ore at Muriel mine. 1.4 Project Objectives . The main objective of the project is to design a suitable crusher layout combination that will result in:
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
We found this interesting article presented by Darcy Flath, Technical Support Engineer, Mineral Industries highlighting the careful planning required to make underground crushing a viable option. “Underground Primary Crusher Plat Design” Underground mining requires careful planning as the processes and challenges are very different from open pit mining.
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.
design equations suitable for hand calculations, and where necessary, guidance for finite element analysis. 1.1 Project Objective The purpose of this guide is to develop design provisions to evaluate the integrity of buried pipe for a range of applied loads. The provisions contained in this guide apply to the following kinds of buried pipe:
Other crushing strengths may be available. For further details consult manufacturers’ sales department. Bedding Classes. The bedding factors indicated below refer to the cross-sectional design of pipes. It assumes that uniform support is achieved along the entire length of the pipeline.
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.
The crushers are built to perform with the lowest cost per ton, featuring a unique combination of crusher cavity design, crushing forces, reliability and safety. Engineered spare and wear parts as well as maintenance and optimization services are designed with decades of experience in different crushers and crushing processes.

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.

Informative papers, studies and articles on trending issues in underground drill and blast mining design. These further compliment the 2000+ pages we have documented in our knowledge base. The files will not only help with learning and using the Aegis software but also the underground mining industry as a whole.
The design of our gyratory crushers and jaw gyratory crushers is based on over Jaw gyratory crusher for underground iron ore mining and the crushing chamber of a BK 63-75 in a stationary copper ore plant Jaw gyratory crusher with specially designed feed opening
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt

(1) Compute the earth load using the Marston method of design for determining loads on rigid conduits, see ANSI A21.1 -1972 or the Concrete Pipe Handbook (1988) for the design method. In addition, the "SAMM" computer program (September 1990), distributed by American Concrete Pipe Association, can also be used for this purpose. In cases where a
The key concepts in the design of Python underground processing plant are described below. COMMINUTION To achieve a low profile / low power consumption process route for the Python many issues were taken into account. Perhaps the most significant is the utilisation of a 2 stage crushing system to achieve a final crush size of P 80
Other crushing strengths may be available. For further details consult manufacturers’ sales department. Bedding Classes. The bedding factors indicated below refer to the cross-sectional design of pipes. It assumes that uniform support is achieved along the entire length of the pipeline.
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.
Real estate in an underground mine is not cheap, so the design of primary crushing plants faces more limitations underground than on the surface. Overhead bridge cranes are the most common in

Our underground mines. Ore is extracted from LKAB''s underground mines by means of sub-level caving. The method is based on creating cavities in the ore body through drilling and blasting. When the ore is removed, waste rock collapses down and automatically fills the cavity. Sub-level caving is based on creating cavities in the ore body and
