Great valves for what is often a very difficult application.

In the drilling and blasting industry we frequently talk about good fragmentation. But what does "good" fragmentation actually mean? It depends on what you are mining and what is around you. (1) Mining waste material? Good fragmentation is defined by what particle size distribution (PSD) fits best with your load and haul fleet. (2) Mining ore material? Good fragmentation is defined by what PSD fits best with your downstream crushing, screening and processing. And this is defined by your commodity type and the end product that you are producing. (3) Mining ore or waste in an area with increased environmental (noise, vibration, airblast) constraints? Good fragmentation is defined by (1) and/ore (2) plus ensuring adherence to the environmental constraints. Your good fragmentation may not be my good fragmentation! An example of this is shown in the image from an iron ore mine in South Africa. One of the aspects that define good fragmentation for iron ore is a small percentage of fines being produced. Simply because iron ore fines sell at a hefty discount to lump iron ore on the market. More detail on the iron ore case study here: https://lnkd.in/dpQkM-SU Copied

Mining Short Notes📝 WHAT ARE THE ADVANTAGES OF HAMMER MILLS USED IN THE MINING INDUSTRY? The advantages of hammer mills in the mining industry include: · High reduction rate: Hammer mills can crush minerals, rocks, and other materials to very small particle sizes, enabling efficient extraction and beneficaling. · Versatility: Hammer mills can be used for a variety of applications, including crushing, grinding, and pulverizing. · Energy efficient: Hammer mills use less energy compared to other milling methods, making them cost-effective for mining operations. · Durability: Hammer mills are designed to be highly durable and can withstand heavy use, making them ideal for use in the mining industry. · Low maintenance: Hammer mills require relatively low maintenance, which makes them cost-effective for mining operations that need to process large volumes of materials.

Good fragmentation is subjective.

This book is recommended to anyone in mining maintenance, as it suggests a model for maintenance work management. But you don't have to be in mining to benefit from this book. One key insight is about allocating resources for planned downtime vs unplanned downtime. Managers tend to pull resources from planned downtime to attend to a seemingly urgent, unplanned downtime. This practice will eventually lead to sloppy planned maintenance works, a reason for more unplanned downtime in the future (breakdown cycle continues) - poor lubrication is one of them. The author suggested managers let planned maintenance work to get all the resources and time it needs for proper completion. Do not take resources away to attend to unplanned downtime despite its urgency. Is this a solution to the conflict of priorities in maintenance? What do you think? I love to hear views from you. #WhatIReadOvertheWeekend  #miningmaintenance

Tonnage and grade At feasibility, by reason of multiple sampling and numerous checks, the average mining grade of some declared tonnage is likely to be known within acceptable limits, say ±5%, and verified by standard statistical methods. Although the ultimate tonnage of ore may be known for open pit mines if exploration drilling from surface penetrates deeper than the practical mining limit, in practice, the ultimate tonnage of many deposits is nebulous because it depends on cost-price relationships late in the project life. By the discount effects in present value theory, late life tonnage is not economically significant at the feasibility stage. Its significance will grow steadily with time once production has begun. It is not critical that the total possible tonnage be known at the outset. What is more important is that the grade and quality factors of the first few years of operation be known with assurance. Two standards of importance can be defined for most large open pit mines: 1. A minimum ore reserve equal to that required for all the years that the cash flows are projected in the feasibility report must be known with accuracy and confidence. 2. An ultimate tonnage potential, projected generously and optimistically, should be calculated so as to define the area adversely affected by mining and within which dumps and plant buildings must not encroach.

What is it that makes “problematic feed” problematic? As the frequency of cleaning events passes 2 per shift (one every 6 hours), an exponential decrease in plant utilisation begins to occur. Each cleaning event, regardless of frequency, requires the mobilisation of an operator to remove process material build up which incurs a 30-minute unscheduled loss. If all of these cleaning events incurred a only one-minute delay, would problematic feed still be considered problematic?
