In mineral processing technology, and especially in aggregate production circuits, comminution plays a crucial role, enabling us obtaining the products with suitable particle size composition. Crushing operations are also very energy consuming ones and are regarded as environmentally burdensome if only due to the excessive noise and dust emission. The article concerns problems of noise generation during operation of crushing devices. Selected types of crushers were under investigations, their noise levels were recorded along with connecting the obtained results with technological effectiveness defined as the comminution ratio and throughput. Results of investigations show that various crushing devices cause different environmental onerousness.
