— All asbestos carries a significant risk, but some types of asbestos fibres (e.g. blue or brown asbestos) have more potential to cause lung damage than others, such as white asbestos. Handling ACMs and soil containing asbestos fibres during groundworks gives rise to significant disturbance compared to a site with buried asbestos in 'normal' use.

The hammer crusher mainly relies on impact to crush materials. The crushing process is rough as follows: The material enters the crusher and is crushed by the impact of the high-speed rotating hammer. The crushed material obtains kinetic energy from the hammerhead and rushes to the baffle and screen in the frame at high speed.
