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...

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...
