COMMINUTION AND CRUSHING
produce more than just a consistent product . “ We are generating a daily performance report and , with the integration of the data for the particle size distribution and cubicity into our Plant Control platform , we target the optimisation of production and minimising downtime ,” they said . “ With this information , we can optimise the crusher setting and plan the maintenance . A mine in South Africa , for instance , recently had great success in increasing capacity and reducing downtime with this .”
As Malone and Hoerschkes mentioned previously , the company is also able to determine the characteristics of the feed coming into the primary crusher through laser scanning .
“ The feed material can be analysed on the truck , including the percentage of the truck load ,” they said . “ This helps the operator to set the right targets for the plant operation and get warnings if the crusher gets material that is too coarse .”
The data is available in real time , allowing an operator to inform the truck driver to blend material in a different setup if required , they added .
FLSmidth ’ s digitalisation efforts do not end here , with the company able to use a simulation tool to more accurately confirm the selection
and overall effects of equipment .
“ To this end , in conjunction with Chalmers University in Sweden , a simulation program has been developed that not only calculates the crusher designation but also the effect on surrounding equipment such as screens , feeders , and so on ,” they said .
Continuous crushing
The ability to effectively design and model wear parts and crusher components for real-world applications also has an impact on both a mine ’ s bottom line and the environment .
Weir ’ s Bradner says the ability to employ “ leading-edge proprietary materials technology ” and design to improve performance and productivity by providing wear parts using ESCO ® crusher liners , tailor made to a customer ’ s application , can tick both boxes .
Metso Outotec ’ s Yanata points to the continuous R & D investments his company is carrying out to find new alloys and bimetallic solutions for crusher wear parts .
“ The MX mantles for primary gyratories , which is a bimetallic solution , was recently
Multotec ’ s custom-made mill liners aim to achieve the balance between liner life , cost , grind efficiency and the structural integrity of the liner by considering the complete grinding
