Crushers can be used to crush a huge selection of materials thanks to their wide range of applications, from recycling to crushing natural stone. Often the crusher is fed with a high proportion of fine material, which unnecessarily passes through the crushing process, increasing wear and energy consumption while reducing throughput. As a remedy, a bar mesh is normally used for pre-screening.
However, if the fine material is damp and cohesive, it can quickly clog up the mesh screen and ends up passing through the crusher anyway. That is why RUBBLE MASTER launched the patented RM Active Grid, a new highly efficient pre-screen that increases material throughput by up to 30% and reduces wear.
| Higher material throughput |
|---|
| Up to 30% more material throughput |
| Significantly better pre-screening of fine material compared to conventional bar mesh |
| Consistent screening performance thanks to self-cleaning effect |
| More efficient crushing process due to low proportion of fine material in the crushing chamber |
| Significantly less machine downtime |
| Reduced wear and energy consumption |
|---|
| Significant reduction of wear in the crushing box (especially with abrasive material) |
| Less wear to the main discharge belt because it is protected by the bypass material |
| Lower diesel/electricity consumption thanks to less stress on the rotor |
| Much lower wear and maintenance costs |
| Additional advantages |
|---|
| High-quality final product |
| Fast return on investment, optimised Total Cost of Ownership (TCO) |
| Saves work (less cleaning, maintenance, material deposits) |
| RM ACTIVE GRID FEATURES |
| Combination of rigid and movable bar mesh |
| Oscillates naturally – does not need its own drive system |
| Optional subfloor made of conveyor belt rubber: quick and easy to install – high flexibility |
| Unique solution – patented by RM |
| Modularity: Can be combined with many other intelligent options for an ideal crusher configuration (e.g. side discharge belt or mesh screen) |
| Hardox bypass chute |
| Unique solution – patented by RM |
