Comparative Analysis of Selected Types of Crushing Forces in Terms of Dust Emission

Selected issues of dust pollution caused by industrial mineral processing operations, were presented in the paper. Two test series of rock material comminution in various crushers were carried out. Dust generation level during operation of each crusher was registered and analyzed from the scope of energy consumption of a device, its throughput and technological effectiveness, measured by achieved comminution degree index (S x ). Results of the analysis show that the proposed indices can help in comparative analysis of effectiveness operation for machines with various capacity or energy consumption. The obtained results also show that the type of comminution forces determines to some extent the dust emission level.
