Mineral Processing Equipment : Howfeed rate affects primary ball millperformance - A type of mining equipment that can trigger the development and change of the beneficiation technology industry. The main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
Inquiry OnlineA lab scale Fryma Co‐Ball mill 0.5 L volume is used and the effects of bead fill 40–70 flow rate 0.1–1 kgmin and rotor speed 7.5–18 ms are investigated. Specific energy is the most effective ways to correlate performance to particle size suggesting that residence time i.e. flow rate is the most important process parameter.
Read MoreAs the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill more accurate than power readings as well as a control of it is

Read MoreLead Mentor: Brent Sullivan Senior Metallurgist Challenge Description Mt Keith was originally designed as a 6 Mta concentrator in 1994. Subsequent expansions and upgrades have taken the nominal throughput to 10.5 Mta however the circuit can rarely maintain a feed rate that matches that. Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade ...

The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si axαi Q z where Q z is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S and the particle size of the maximum is related to ball diameter by xm k1d2.
