New Jersey-based Allu Group Inc.’s Mining Series is an (M-Series) all-in-one screener crusher attachment for mining and aggregate. The M-Series processes a wide variety of mined materials, including coal, oil shale, limestone, dolomite, gypsum, phosphate, salt and other soft rock and attach to both wheel loaders and excavators. With the extraction of resources from the ground becoming ever more expensive and complex, Allu’s processing bucket converts a wheel loader or excavator into a high-capacity mobile pre-crushing and screening solution, which can place material either into stockpiles or directly into trucks. It reduces both capital investment and operating costs for the mine owner, while also significantly reducing equipment wear life, production time and operating costs. Pre-crushing, screening and loading are achieved in one initial step with a processor that can easily be transported around a site on a loader and/or excavator. These attachments can be utilized 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. A typical bucket of material can be crushed and processed in less than 60 seconds, providing a processing capacity of up to 650 tons (590 t) per hour. There are six M-Series models, each with the ability to produce three to four different fragment sizes and fit wheel loaders from 30 to 90 tons (27 to 81.6 t) as well as excavators from 50 to 160 tons (45 to 145 t). The rear-mounted drum and bearing design uses three or four rotating crushing drums that are powered by a hydraulic motor.

The hydraulically-operated hinged mount plate on the wheel loader models, 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. (10 cm) range, the M-Series screener crusher mount plate position directs material flow protecting the carrier from stray material.

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.
