New Jersey-based ALLU Group has introduced its new Mining Series all-in-one screener crusher attachment for the mining industry, known as the M-Series. It will make its North American debut at CONExpo from March 4-8, 2014, which will be attended by International Mining. The M-Series is being used to process a wide variety of mined soft rock materials, including coal, oil shale, limestone, dolomite, gypsum, phosphate, salt and other soft rock. Users include Eesti Energia’s Narva oil shale mine in Estonia.
The company states: “ALLU’s innovative processing bucket loads, carries, crushes and places material either into stockpiles or directly into trucks. It converts a mine’s wheel loader or excavator into a high-capacity mobile primary or secondary processing plant, reducing both capital investment and operating costs for the mine owner. Crushing, screening, mixing and loading are achieved in a one step process that can easily be moved around a site on a loader and/or excavator. These attachments can be utilised in both open-pit and underground mining applications without the need for the huge capital costs associated with a stationary crushing and screening plant. The ALLU M-Series attachment allows the processing machine to be brought to the material and not the material to the machine.”
Purpose-built to match the mining industry’s need to aggressively engage the materials bank, the M-Series screener crusher buckets are strategically positioned out in front of the carrier when mounted on a loader. A typical bucket of material can be crushed and processed in less than 60 sec providing a processing capacity of up to 650 t/h. There are four M-Series models, each with the ability to produce three to four different fragment sizes and fit wheel loaders from 50-140 t as well as excavators from 60-250 t. The hydraulically-operated hinged mount plate allows an M-Series screener crusher attachment to also be used as a loading bucket, above and below ground, with normal load-and-carry characteristics, including maximum breakout force.
When processing material to produce different finished product sizes, typically in the >4 in range, the M-Series screener crusher mount plate position directs material flow protecting the carrier from stray material. The patented rear-mounted drum and bearing design uses three rotating crushing drums that are powered by a hydraulic motor. Installation of the M-Series screener crusher includes a wired control panel located inside the operator’s cab of the carrier machine. This monitors key data to the screener crusher’s performance, including hydraulics, temperature and bucket angle, as well as providing a link for real-time ALLU after-sales service. As with standard buckets, the M-Series screener crusher is designed with changeable wear parts.
