Simulation of charge motion in ball mills. Part 1

A numerical tool known as the discrete element method (DEM) is used to study the motion of the ball charge in ball mills. In particular, the motion of individual balls in the ball charge is simulated. An interesting aspect of this simulation is that it yields the frequency distribution of ball collisions as a function of collision energy.

A Study of Charge Motion in Rotary Mills, with Particular

The motion of balls deep within the charge of a rotary grinding mill was investigated. Novel investigative techniques were used to track the motion of the balls, including X-ray filming at 50 frames per second of both the front and side views of a transparent mill, and gamma-camera filming of a radioactive ball. Analysis of the trajectories of the

Rock Crusher at Best Price in India

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
