The GOLD ROCK BREAKER 777 is a patented design in Australia and is currently pending in the US. It 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 777 packs a punch for its size. With dry material It can deliver up to 300kg per Hour of fine crushed product. The replaceable Carbon Steel impact bars have a rating of 67 HRC. Giving you long lasting wearing capabilities.
There are 4 interchangeable bottom screens available. So you can alter the size of the output material.
The screens are held in place by 4 quick release heavy duty latches so if you run the engine out of fuel or you want to clean the cylinder and screen, access is quick and easy.
Also the four bolt flange bearings are positioned to be greased easily. The two drive belts can be adjusting by the engine tightening bolt.
Everything on this machine has been made with the operator in mind. The goose neck feed hopper ad gravity flap stops the possibility of rocks coming back out. Electric start engine fly's over providing the cylinder is clear of rock.
Manoeuvrability is a plus with this machine, it's compact and has flat free tires with a sturdy lift handle.
