Welcome to MSC Industrial, this is Larry the Machinery Guy. Today, the purpose of this video is how to measure a DRO for a milling machine. We're going to cover all 3-axis or 4-axis of the mill, and what I've done is I position my x-axis all the way over to the far extreme, I put a witness mark here at that far extreme—we don't want to expose the ways.
Measure operating range — low end is LRV, high end is URV, difference is Span; Calculate % span through the range: Operating valuex = (% desired x Spanx) + LRVx; Example: What is the 35% point in a temperature scale that reads between 55 and 172 deg F? LRV = 55 deg F; URV = 172 deg F; Span = 117 deg F (172 F — 55 F) (.35 x 117 F) + 55 F = 96 F
How To Measure Unit Mining Mill; Mill (grinding) Wikipedia. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.
Measurement requirements. The mining company uses flowmeters for pulp measurements in one of the last phases of its production process after the dewatering has taken place. The pulp is highly abrasive and has a high density of 1.24 g/cm 3. The flow rate per pipeline is 10.500 m 3 /h. The temperature of the slurry varies between +3 °C / +37.4

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
Performance Measurement of Mining Equipments by Utilizing OEE Sermin Elevli1 and Birol Elevli2 Over the past century, open pit mines have steadily increased their production rate by using larger equipments which require intensive capital investment. Low commodity prices have forced companies to decrease their unit cost by improving productivity

Mining Mill Operator Training. The most important rule governing the accounting of a processing plant or unit operation is that mass can be neither created nor destroyed. Mass In = Mass Out. The Marcy scale is a common tool used in preparation plants to measure pulp density.

mill discharge product size in relation to the lifting effect of the liners. In this specific case, it is obvious that a certain load expansion is needed to allow the coarse particles entering the media charge to be reduced. Therefore, at this stage, a direct measurement of the dynamics in the mill gives very valuable information to the operator.
Nov 01, 2019· One millimeter is one one-thousandth of a meter. There are a couple ways to measure millimeters. The first and simplest method is to use a metric ruler, which is conveniently labeled with millimeter markings. The second is to use basic math to convert another unit of measurement, such as centimeters, kilometers, inches, or yards, into millimeters.
significant improvements in mine efficiency, mill throughput and reduced operating costs at mines around the world (Dance et al, 2006). For example, increases in mill throughput of 5 to 20 percent have been measured at some sites. The PIO methodology is described in this paper, and a case study is presented demonstrating the application
Another unit of measure, the radian, is used mainly by militaries in artillery, tank, and mortar gunnery. There are 2 PI radians in a circle. PI is a constant of approximately 3.1416. That is 2 * 3.1416, or 6.283 radians. Divide each radian into 1000 mil-radians and you see there are 6283 mil-radians in a circle.
Jul 15, 2020· Vibration is the movement or mechanical oscillation about an equilibrium position of a machine or component. It can be periodic, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. Vibration can be expressed in metric units (m/s 2) or units of gravitational constant “g,” where 1 g = 9.81 m/s 2. An
A unit of measurement is a standardised quantity of a physical property, used as a factor to express occurring quantities of that property. Units of measurement were among the earliest tools invented by humans. Primitive societies needed rudimentary measures for many tasks: constructing dwellings of an appropriate size and shape, fashioning clothing, or bartering food or raw materials.
Every mining operation has a unique grinding process. Metso has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG mills in the world.

For conducting a mining project’s break even analysis, you first need to know about the operational expenses (OPEX).When the OPEX is known, you can calculate the mineral’s cut off grade, which is the break even grade, below which it is not economically viable to mine the ore.To find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn’t available, I refer you
