Availability Availability takes into account Down Time Loss which includes any Events that stop planned production for an appreciable length of time usually several minutes long enough to log as a trackable Event. Examples include equipment failures material shortages and changeover time.
equipment working between upstream mining and down-stream mineral refining processesis in a unique posi-tion to reveal the location of a bottleneck in the value chain of the continuous refining process. If you ask mine production staffers how well a mine is running they will look at the hoist performance to see
Focus on reducing equipment failure that can lead to significant amounts of major downtime impacting availability and thus OEE. For More Information This Executive Summary contains a small subset of the insights and actions that organizations can takeboth strategic and tactical to improve performance.
Performance measurement is a fundamental principle of management. The measurement of performance is important because it identifies current performance gaps between current and desired performance and provides indication of progress towards closing the gaps. Carefully selected key performance indicators identify precisely
Overall Equipment Effectiveness OEE is a well-known measurement method which combines availability performance and quality for the evaluation of equipment effectiveness in manufacturing industry. However there isnt any study in literature about how to use this metric for mining equipments such as shovel truck drilling machine etc.
Wattum Store - Your Mining Equipment Broker Products. Wattum is one of the main equipment brokers in the US and Canada. We are here to provide you with optimal equipment for your farming needs. We also offer financing solutions.
Mining KPIs Weve assembled a collection of sample Key Performance Indicators for you to use as a starting point when building scorecards. These sample KPIs reflect common metrics for
performance using equipment fdure and repair time data are presented. The efficacy of these techniques is illustrated through a case study of the mobile equipment in an underground mine operating at high altitude. Data 6om the case study is analyzed and recommendations for improvement in the maintenance process at the mine are made.
Oct 01 2000 miscetde20128182 title Failure and downtime reporting -- a key to improve mine equipment performance author Paraszczak J abstractNote High productivity of the equipment employed in mining has a direct beneficial effect on the cost of the operation. Increased equipment availability can be achieved by identifying the most adverse factors that affect availability which is
Everything in maintenance revolves around humans and machines. Optimizing the performance of people and assets is crucial to maintenance success. Thats why the most widely-used maintenance metrics address the way equipment and people work. There are three main categories of maintenance metrics asset operational and inventory metrics.
Inherent availability is the steady state availability when considering only the corrective downtime of the system. It is defined as the expected level of availability for the performance of corrective maintenance only. Inherent availability is determined purely by the design of the equipment. It assumes that spare parts and manpower are 100 .
The measurement of mining equipment performance has evolved. Initially the measurement was done using singlemeasurement indices such as machine availability production index and utilisations .
Aug 01 1992 The mining equipment reliability is one of the application areas. Generally the downtime costs of mining equipment are high. For example accord- ing to Ref. 162 the cost of one days lost production due to equipment breakdown could be as high
Mar 22 2013 availability and utilization of mining equipment. As a leading global manufacturer of crushing and milling equipment we offer advanced rational solutions for any size-reduction requirements including quarry aggregate grinding production and complete plant. We also supply individual crushers and mills as well as spare parts of them.
This is the role of Availability Performance and Quality. In the preferred calculation you get the best of both worlds. A single number that captures how well you are doing OEE and three numbers that capture the fundamental nature of your losses Availability Performance and Quality.
Availability is an important metric used to assess the performance of repairable systems accounting for both the reliability and maintainability properties of a component or system. Did you know though that there are different classifications of availability and different ways to calculate it This article will explore the different availability classifications what they mean and how they .
Overall equipment effectiveness is a maintenance KPI that measures an assets level of productivity. OEE is a combination of three factors that tell you how efficient an asset is during the manufacturing process asset availability asset performance and production quality. Each one can tell you something different about how an asset operates.

OEE for mining equipment OEE applications in mining industry differ from manufacturing industry. Therefore it is necessary to develop equipments own classification framework for the losses which should be associated with the components of availability performance and quality 16. The necessary data classification
Trakindo accepted the challenge to deliver that goal providing a reliable fleet of mining equipment that would enable the site to achieve production goals at the lowest cost per tonne he says. Machine availability at Batu Hijau was at 86 percent says Flores with a goal of moving that up to the 90 percent benchmark.
