2D Model for Ball Mills. F. Campo1, J. Escobar1 Abstract

Ball mill is one of the more intensive used equipment for milling-blending operations and its design is based, normally, on experimental data and some non-dimensional numbers for size scaling [1,2]. Due to the coupling of diverse phenomena that occurred during the milling-blending processes, the models reported are complex. This work develops a

In a ball mill, the collisions between two balls or a ball and the mill wall are expressed by a Voigt model that expresses elastic spring (spring coef-ficient K) where elastic and inelastic properties of the objects are introduced between the points of contact as shown in Fig. 1and the viscosity dashpot (damping coefficient ). In addition, a friction slider (coefficient

Grinding in Ball Mills: Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The starting material can be loaded either through a spout feeder or by

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the
