Chutes liming

Wearback™ chutes are designed with a series of curved and straight ledges allowing material to build up throughout the transfer, forming a layer of material as the wear medium. This so-called rock-on-rock chute design increases wear-life on average by up to 400% compared to conventionally lined hood and spoon style chutes.

Designing reliable transfer chutes with bulk material

When the final design 3D model is adequate, we will run a DEM simulation of the chute which we then use to optimize the final chute design. Here is a real-case example of a project we worked on for a client. A vertical Ore Pass section of approximately 105 meters is filled with Kimberlite. The material can drop 105 meters and impact onto a

BULKtalk: Best practice in chute design Part one

Apr 02, 2019· Chute systems are easier to design if the geometry of the plant provides in-line or right-angled transfers. Other alignments are feasible but may require more space or height for an effective design. Chute systems are always a compromise if there is insufficient space and height in the layout for all required functions at the detail design stage.

Taking Intelligence Underground Variant Mining

The ore then collapses or “caves” gradually under its own weight. The resulting rubble funnels through a series of vertical ore passes at various levels in the mine. A chute system is located at the bottom of each ore pass. “The chute is a device that allows ore to be transferred safely to the haulage vehicles,” Meloche explained.

mining engineering: Passes, Bins, and Chutes

Sep 20, 2010· Ore passes often lead to an underground storage bin to provide surge capacity in the ore stream. In turn, the ore is normally drawn off the bottom of the bin into a chute. The design of passes, chutes, and bins was once a simple exercise and the operations were relatively trouble-free.

The particular chute allows for fine wet-sticky material (-8mm) at 16,000tph. This provided a significantly improved surcharge angle on receiving belt compared with previous chute and in addition to higher volumes of ore through the chute. Increased maintenance shutdowns in excess of 52 weeks, both for chute and deflector.
