Electronic ear in SAG mill | Automation & Control

Aug 25, 2004· We have an appliion in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 4-20mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.

Grinding in Ball Mills: Modeling and Process Control

grinding process [15, 18, 22, 28]. A comparison between ball mils and cylpebs is made in [ 42]. The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (aracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the

Increasing availability through advanced Gearless Drive

time-taking grinding out of the ball mill. Ball mills with Energy savings typically up to 750,000 USD per annum for a 20 MW SAG mill considering a power supply price of 11 US Cents per kWh. Erection and commissioning works on site are reduced by using a completely installed, wired

What is the Difference Between 3 Phase and Single - VEICHI

Single-phase motors are widely used in refrigerators, washing machines, air conditioners, electric fans, hair dryer, vacuum cleaners and other appliances. And these motors can work with great efficiency when they are equipped with frequency converters. Three-phase motors are widely used in large wind turbines, belt conveyor, and hoist.

Electric Motors The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, i.e. 1750 rpm or 1170 rpm for 60 Hz appliions and 1450 rpm or 970 rpm for 50 Hz appliions. The advantage

Electric Or Hydraulic Motors Whats The Difference

Electric Motors – An electrical linear actuator converts electrical energy into torque by connecting the motor to a lead screw, which is then rotated against a fixed ball nut or threaded lead. When the screw rotates, the nut is driven along the threads, thereby producing torque.

Electric motor - Wikipedia

An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor''s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor''s shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles
