Edge Innovate has introduced a new mobile mineral sizing solution to its materials handling equipment range.

The new RS1500 builds on the success of new products launched in 2013 such as the Slayer XL, the MS100 and the 360° Unlimited range. 

Designed by the Edge team as one of the most efficient mobile mineral sizing solutions available on the market today, the new RS1500 roll sizer can process a wide range of materials including coal, lignite, bituminous, sub-bituminous hard-to-handle materials, graphite electrodes, sticky materials, friable materials, soft ores, limestone and limes, salts, glass, fertiliser, recycled concrete and tarmac. 

Robustly designed with high manoeuvrability and a small footprint, the RS1500 is a formidable option for the quarrying and recycling sectors.

The RS1500 offers an impressive list of design features including a highly efficient hydraulic drive system, tramp metal release, easy select piece sizing controls, intelligent hydraulic load sensing system and a five-function remote control. 

The full HMI controlled panel interface provides easy fine tuning for accurate application performance. The HMI allows for automatic start/stop operation and provides visual data output such as engine load, individual shaft pressure, hydraulic oil temp and fuel consumption during operation. 

Powered by a Caterpillar C9 260kW (350HP) engine designed to meet Tier IV regulations, the RS1500 has the capacity to process 250 tonnes per hour with a maximum feed size of 400mm. The C9 engine offers full torque while only consuming 25-30 litres per hour.

Material is fed into the RS1500 7m³ hopper and carried to the pre-screen via the 1400mm wide heavy duty belt. Full length impact bars prevent sag reducing material rollback and take impact from feeding material, prolonging the life of the conveyor belt. Variable belt speed controls the flow of material to pre-screen while the feed hopper featuring a hydraulic sliding function enables quick transition from transport to operating position. 

A single deck, two bearing pre-screen allows fines to bypass the chamber, increasing processing efficiency and throughput. An optional side conveyor can be retrofitted to stockpile diverted fines separately.

The Roll Sizer chamber has the ability to handle wet and sticky material and employs an intelligent load sensing system to prevent overload. The tooth rotor design allows undersize material to pass through the precision designed shafts increasing product throughput. The shafts are designed to grab the feed material and reduce it to the desired product size while creating the minimum of fines. 

An automatic sensing system in the RS1500 protects the roller shafts against tramp metal or trapped material, reducing maintenance costs and downtime. The chamber houses two variable speed reversible roller shafts for accurate piece sizing, both of which are independently driven and controlled via the HMI control panel. The feedbox enclosing the chamber not only feeds material from the pre-screen into the chamber but also prevents debris and dust from exiting the chamber. Removable plates are provided to gain access to the chamber for maintenance. 

Material is stockpiled via the 1150mm wide, heavy duty ply product conveyor, which provides a discharge height of 3560mm creating a stockpile volume of 77.5m³ or 125 tonnes. 

The Edge RS1500 roll sizer is being showcased at CONEXPO in Las Vegas from 4 March to 8 March in the brand new Platinum Lot #9338.
