The GRB 777XL has taken a few years to perfect, with endless hours in the workshop. Having 40 years mining experience between my father and I, we know what it takes to build a crusher super tough and reliable.
The GRB 777XL Rock Crusher is built for the serious prospector and small scale miner. It is capable of crushing approximately 500kg per hour with our largest bottom screen.
The Impactor bars are made Hardox 500 Steel giving you the long life and great wearing capabilities. Replacement impactors bars are readily available.
There are 4 Interchangeable Bottom Screen available. So you can alter the output size of your material. Also the slots on the Bottom Screen are tapered from inside to outside. This helps to reduce the chance of material becoming clogged in the screen slots.
The screen are held in place with four heavy duty quick release clips so if you run the engine out of fuel the cylinder can be cleared out easily. Also makes cleaning the screen slots quick and simple.
There is many safety features to protect the operator including the design of the feed hopper and the gravity flap to eliminate any rocks coming out the top.
The frame has four flat free tyres and has great maneuverability.
