New Impact Crusher Delivers High Reduction Ratios with Low Energy Usage

A paper presented at the International Comminution and Classification Congress 2015 (ICCC 2015) held in San Luis Potosi, Mexico, in August, titled Breaking down comminution barriers – new dimensions of particle size reduction and liberation by VeRo Liberator, describes the technology employed by a new type of impact crusher that is claimed to offer dramatic improvements in particle size reduction ratios along with lower energy requirements. The paper, authored by Gregor Borg, O. Scharfe and A. Kamradt, calls attention to the well-known fact that “…the comminution of commodity particles such as mineral ores by crushing, grinding, and milling makes up the biggest single cost factor in mineral processing,” and goes on to explain that a German engineering company has invented and produced an innovative high-velocity impact crusher, the VeRo Liberator, featuring improved particle size reduction ratios and high levels of particle liberation together with low energy consumption and operational noise. It operates without using any water.

Industry’s Biggest Flotation Cell Expands Optimization Options

Frank Traczyk, director of flotation at FLSmidth, believes the mining industry’s need to address declining grades, along with pressure to reduce capital and operational costs, puts a similar burden on original equipment manufacturers (OEMs) to leverage technology to provide effective solutions that meet customers’ demands. A recent outcome of this effort at FLSmidth culminated in the development of the company’s new 600 Series SuperCell flotation machine. With an active volume of 660 m3, the massive cell is considered to be the world’s largest operating flotation cell and makes it possible for users to take advantage of economies of scale.
