Natural Resources Canada, Ottawa, Ontario has a requirement for the development of a 3-D Free Falling Rock Sizing Photo Sensor Prototype.
The mine-to-mill holistic approach is an entire mining and processing optimization system from the blasting to the comminution circuit, which attempts in economic and energy saving opportunities. One of the causes of the low efficiency of the grinding mill is the high variability of the run-of-mine ore hardness and size distribution feeding the process. Accurate measurement of those two perturbations is the first step in developing process control strategies that will minimise their impact on mill efficiency.
A number of photo-sensors were developed over the last twenty years for measuring the size distribution of the ore feeding the mill. Despite the recognition of some important sampling errors, most of them were found efficient for measuring ore size distribution over a conveyor belt and under a controlled light environment. The challenge is now to measure more accurately the ore size distribution before crushing. Accurate measurement of run-of-mine ore size distribution before crushing is a requirement for assessing the blast efficiency, for reducing the sampling error and for developing the rock hardness soft sensor, which requires an evaluation of the size reduction ratio achieved by the crusher.
In a previous gap and technical feasibility analysis, three imaging technologies have been evaluated for this purpose in collaboration. Laser 3D profiler was identified as the most promising technology while linear camera was viewed as an interesting 2-D technology compromise. The objective of the proposed research work is to build the prototype of a 3-D free falling rock sizing photo sensor.
