Currently, one of the main problems in the extraction of useful minerals in term of environment is their transport in quarries. With the requirements to reduce the noise of the belt conveyor track, we were looking for a suitable solution to reduce it. So, we started thinking about attaching rollers made of a material other than steel. The final solution was to insert classic rollers in polyurethane beds called suspension cartridge - which are roller holders made of polyurethane and reinforced with a steel liner to...

Today, there are high demands for ecological solutions to the problems associated with all human activities, and therefore there is great pressure on surface mines to contribute to the reduction of dust and noise in the extraction of raw materials. Under this pressure, the mining company is trying to find a solution that would benefit all parties - ecologically and economically. The noise level of belt traffic in surface quarries, especially at night, exceeds 60 dB, which significantly disrupts the surrounding pop...

Cases of breakthrough on conveyors belt occur very often during the transport of heavy material in surface mines. The annual cost of their repairs in the Czech Republic is around two million euros. Therefore, we expected a constructional solution for impact points, which would reduce the dynamics of impacts and thus prevent to destroy the conveyors. In addition to reducing the number of punctures on conveyor belts, there has also been a significant reduction in dust in the area of transfer points. This article the...
