ACA crusher – recycling of mineral wool and
Besides the environmentally friendly crushers the machines are very quiet. With a noise level as low as 75 DB at a distance of 1 metre from a machine running on empty this is very sattisfying. One of the main reasons for the low level of noise is that the machine runs with only 15 RPM. And the slow turning crusher also produces a minimum of dust.
