With the release of Cavex 2 650, Weir Minerals has strengthened its Cavex hydrocyclone series, combining digital technology to achieve process improvements.

Throughout the trial period, Cavex 2 650 produced efficiency and bypass improvements, showing the potential for conversion into brownfield site operating savings and greenfield project capital expenditure reduction.

The Cavex 2 hydrocyclone series marks a new era in separation technology. The size of its LIG+ advanced laminar spiral inlet and feed chamber is different from any other cyclones on the market, and its capacity and performance have been increased by 30%.

Cavex 2 650 goes one step further. The 650 model has undergone years of research, laboratory testing, and field testing to ensure that it can withstand the rigors of heavy industrial and abrasive applications.

To fulfill environmental protection obligations, by reducing the bypass back to the mill, the new cyclone separator reduces the fine powder returned to the mill during the grinding process, thereby reducing the energy demand for further processing of particles.

For finer separation, Cavex 2 650 can be operated at lower pressures to ensure further energy savings or increase feed density to reduce water consumption.

Cavex 2 650 has other advantages, such as an average improvement of more than 15% in the bypass, reduced turbulence during the separation process due to the LIG+ inlet and elongated chamber design, and enhanced performance by enabling the Synertrex monitoring system.

Enabling the Synertrex monitoring system can detect ropes or blockages in advance to achieve continuous and efficient operation of the hydrocyclone.

The Cavex 2 650 hydrocyclone was proven in tests in Chile, where it was tested in a large copper mine in Chile, which had a semi-automatic mill in a closed loop with a cluster of cyclones.

The test tested a Cavex 2 650 in a six-position cluster of existing Cavex cyclones. Compared with the original cluster, the cycle load increased by 48.5% and the water bypass performance increased by 31.7%.

The Cavex 2 650 hydrocyclone is the second in a series of standard sizes that Weir Minerals plans to release, and more sizes are being developed to expand the current product range.
