Double roll crusher

This is the machine I designed for my thesis project. Some native plant species in the south west have seeds with extremely tough outer shells, which help them withstand adverse conditions. But when rehabilitating a minesite, we need seeds ready-to-go, they can’t be sitting around in the soil for years before germinating. This machine is able to crack the outer shell without damaging the seed embryo inside – the gap between the rollers can be adjusted to give the perfect amount of cracking effort. In addition, it’s designed to be ergonomic and easy to use and maintain.
