UK-based engineering company Weir Group has launched the Cavex 2 650, a hydrocyclone designed to increase operational savings at brownfield sites and cut capital expenses for greenfield projects.

The company commented that the new 650 model is part of an effort to improve efficiencies and cut emissions during milling processes.

It said the new technology could reduce the amount of energy used during milling by cutting the bypass returning to the mill; this would free up mill capacity.

According to the company, the technology can increase operational and circuit capacity by up to 30%, maximise plant recovery by reducing the quantity of misclassified particles by 10% and reduce bypass capacity by 15%.

Additionally, the company said the technology has undergone "years of research, lab testing and in-field testing" to function daily operation in heavy-duty environments.

It comprises a robust metal casing with an elongated chamber design. The company said this guarantees reduced turbulence inside the cyclone, enabling increased volume and efficiency during the process.

Mine-site trials at a copper-ore mine in Chile improved 48.5% in circulating load and a reduction in water bypass of 31.7%.

"The Cavex^® 2 650 hydrocyclone can be customised to suit almost any application with a variety of spigots, vortex finders and cone angles," it explained.
