Crown Gravity Separators

From farming to recycling, Crown gravity separators are used worldwide to improve the quality of the sample and separate efficiently by specific weight any granular type commodity that cannot be separated by screening (width), aspiration (weight) or indented cylinders (length).

Through decades of experience building and using gravity separators, Crown can offer a tailored and cost effective solution that suits your needs.

We take great pride in our work and consequently our separators are as renowned for their streamlined, space saving design, durability and engineering excellence as for their best in class separation capability.

In addition to the Crown Gravity Separator range, which includes tailor made dust hoods, air slides & interchangeable decks, we also design and build elevators, conveyors and de-stoning equipment in-house, enabling us to offer the complete end-to-end solution to our customers.

Crown Gravity Separators are used to improve the value of crop by rejecting a portion as necessary e.g. Hagberg improvement of milling wheat using a gravity separator as an integral part of a grain handling system. Gravity Separators are also used on all modern mobile seed processors. See


Crown Gravity Separators are also used in recycling applications such as separating valuable or viable metals, granular polymers, chipped waste tyres & mineral, rock or soil types.
