End Mills

Guhring is somewhat unique amongst carbide end mill manufacturers in that Guhring produces its own carbide rod, which is the substrate material for all Guhring carbide end mills. This ability to control the quality and supply of carbide rod gives Guhring carbide end mills longer and more repeatable tool life and performance. Guhring was also one of the first manufacturers to offer a

Feed Rates Explained

Feed Rates Explained – Extend the Life of Your CNC Tools and Machines. Feed Rate is one of the most important factors to consider when implementing any CNC strategy. Simply put, feed rate is the speed at which the cutter engages the part and is typically measured in units/minute. Suggested cut feed rates will vary depending on the type of

Environmental Strategies in the Mining Industry: One

Metal concentrations in ore vary greatly, from less than 1 percent by weight for most gold deposits to over 60 percent for some iron ore deposits; most metallic mineral deposits have ore grades in the range of 1–5 percent by weight. Beneficiation, sometimes called milling, usually occurs at the mine site.

How it Works: Crushers, Grinding Mills and Pulverizers

02-06-2017Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles

Enzymes: principles and biotechnological applications

21-03-2022Enzymes are potent catalysts. The enormous catalytic activity of enzymes can perhaps best be expressed by a constant, k , that is variously referred to as the turnover rate, turnover frequency or turnover number.This constant represents the number of substrate molecules that can be converted to product by a single enzyme molecule per unit time (usually

Detour Lake Gold Project, Ontario

The Detour Lake mine is a gold deposit located in Ontario, Canada, approximately 8km west of the Ontario-Qubec border and 180km north-east of Cochrane. The 376km property lies within the premises of the former Detour Lake mine that was operated between 1983 and 1999 by Placer Dome and produced 1.8 million ounces of gold. The

The Magic of Manganese Dioxide: What It Is and Why You

03-03-2013Example: A phosphate result with a 1.0 mg/L (ppm) detection level will not work for arsenic applications. Arsenic is measured in parts per billion. Phosphate results should be expressed in ppb (ug/L). Ask for phosphate results at a 0.15 mg/L detection level and 0.05 mg/L for phosphorus. Hydrogen sulfide reduction

Metering Pump Principles

Although a metering pump can generally be adjusted to pump at any flow rate between 0 and its maximum capacity, its accuracy is measured over a range determined by the pump's turndown ratio. Most metering pumps have a turndown ratio of 10:1, which simply means that the pump is within its accuracy rating anywhere between 10% and 100% of capacity.

Modelling SAG milling power and specific energy

inside the mill and it is composed of balls, ore and water. The ball charge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric ﬁlling which depends on the ore size distribution (spe-cially the % +600 and the % 600 +100), on the rotational speed (N/Nc)

What is a Variable Frequency Drive?

20-03-2014A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.. Frequency (or hertz) is directly related to the motor's speed

Rotary Dryers: The Ideal Choice in Processing

Rod mills, how they function

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Speed

When selecting a stepper motor, you try to pick a motor that meets your speed and torque requirements plus some safety margin. But how do you compare motor performance between motor suppliers. Most suppliers provide speed – torque characteristic curves to provide an idea of what performance can be expected from a motor. Stepper motor speed - torque curves show

The Kinetic

The Kinetic-Molecular Theory Explains the Behavior of Gases, Part I. Recalling that gas pressure is exerted by rapidly moving gas molecules and depends directly on the number of molecules hitting a unit area of the wall per unit of time, we see that the KMT conceptually explains the behavior of a gas as follows: Amontons's law.

Air Compressor Types and Controls

Variable Speed Drive (VSD). This control method varies the speed of the compressor to respond to changes in air demand. Both lubricated and oil free screw compressors can be purchased equipped with variable speed drive controls that continuously adjust the drive motor speed to match the variable demand requirements and maintain constant pressure.
