comes down to cost per tonne and uptime.” Purchase price remains important, but customers also want to understand production, fuel or electricity consumption, wear costs, maintenance requirements and the availability of technical support and spare parts. This focus is influencing how Keestrack approaches equipment selection. Rather than simply recommending the largest machine available, the company assesses the feed material, particle size distribution, abrasiveness, moisture, required finished products, and production target before recommending a crushing and screening combination. Drive options can also be simulated to determine whether an electric solution could provide a better return on investment and lower total cost of ownership. “The highest throughput on paper does not always translate into the lowest cost per saleable tonne in actual operation,” says Pandit. Screening is an important part of this calculation. Pre-screening material that does not need to pass through the crusher can reduce unnecessary crushing, wear, and energy consumption, with a direct impact on operating costs. Flexible power for African conditions Electrification is a major development in mobile crushing and screening, but Keestrack does not view diesel and
For Africa, I don’t see the discussion simply as diesel versus electric. The real question is which energy source gives the customer the lowest sustainable cost per tonne at that particular site.
