Environmentally sustainable solutions

There are more and more demands for reduced dust and noise not only in urban areas but also in quarries.

Reduction in dust and noise is increasingly demanded both in urban areas and in quarries. Stipulations by local authorities with regard to the observance of limit values are becoming more and more strict. Regulations that vary considerably according to the region specify how loud building sites can be in urban areas or how much dust can be emitted. The aim is to protect the affected population and environment, as well as workers on site.

Solutions for effective noise reduction

Apart from the crushing process itself, the main noise pollutant on the mobile crushing plants is the power pack. Most sound emissions are caused by the air pipework, the cooler and air swirling in the area of the power pack base.

Reduction in the minimum distance to the machine without hearing protection of up to 60% (at 1,800 rpm)

An optional package can help in this case: it consists of ergonomic noise insulation flaps, installed level with the engine, which deflects the noise upwards. The flaps are folded against the plant for transport and therefore do not affect the transport width. The power pack base has also been closed to make it soundproof.

Qualitative reporting: measurement at 1,800 rpm > Basis: measurement by an independent acoustic laboratory

Result: Reduction in noise by 6 decibels (3 decibels alone amount to halving of the noise perception of the human ear)

Solutions for effective dust containment

The technical nature of recycling and natural stone processing applications means that a relatively high level of dust is generated. The main causes of dust emissions are the material discharge and transfer points and the crushing unit itself.

The solution is water spraying at strategically important points, such as the crusher inlet, the crusher discharge conveyor, the side discharge conveyor and the secondary screening unit. Most of the dust is therefore bound and its spreading is prevented.

Result: A reduction of dust volume by up to 50% (depending on the material)
