Perm Polytechnic scientists have developed unique cutters for the mining industry. The innovative design of the tool not only saves energy, but also significantly increases the service life of the equipment.
Specialists from Perm Polytechnic University presented a new solution for the mining industry – a cutter model RS-55 with improved geometry. This is an important step in increasing efficiency production minerals.
The development allows reducing energy consumption during rock destruction by 15–30%. At the same time, engineers managed to extend the service life of the equipment. The design of the tool provides for convex cutting surfaces. If one side wears out, you can simply turn the cutter over and continue working, which eliminates frequent replacement and reduces downtime.
To test the effectiveness of the new design, scientists created a special laboratory stand. The physical model of the cutting process was equipped with high-precision sensors that recorded force changes at a frequency of 1000 times per second. The tests used gypsum boards that were as close in structure as possible to potash ore.
The experiments were carried out in different operating modes with varying penetration depth and cutting step. Particular attention was paid to the chess pattern of work, which has proven to be highly effective. This scheme provided an additional reduction in energy consumption due to the destruction of rock along existing cracks.
The introduction of energy-efficient cutters from Perm Polytechnic University opens up new opportunities for the mining industry. Businesses can significantly reduce operating costs and increase overall productivity. The innovation has already proven its effectiveness in laboratory conditions and is ready for industrial use.
The material was prepared with the support of the Russian Ministry of Education and Science as part of the Decade of Science and Technology.
