Portafill impact crusher MI-8RSponsored
The market for compact crushers and screens is growing in New Zealand and Australia. Along with construction and demolition projects, construction waste is providing new opportunities for businesses to earn additional profits. UK brand Portafill is widely recognised as a market leader whose innovative designs spawned the growth of compact crushing and screening over the last 15 years.
Designed with versatility in mind and ease of use in a variety of rock types and a number of recycling applications, Portafill builds its machines to be compact, easily transported and efficient.
The MI-8R is a modern compact impact crusher, ideally suited to crush concrete, rubble asphalt and medium stone. Unique to its crusher counterparts, it breaks apart rocks and stones by rapidly striking the material as opposed to utilising a pressure force.
The impact crusher's rotor is a 4 blow bar with the crusher opening measuring 820mm x 600mm (32” x 24”), an improvement on the previous MI-7R that had a smaller opening. The crusher drive is direct drive from engine via belts and is built with crusher overload protection.
The MI-8R can be fitted with a hanging screen, a recirculating screen and a conveyer system that returns oversized material to the crushing unit to enable more productivity.
