Spiral Separator
High-capacity gravity separator dividing round grains from flat or broken material.
Product datasheet available on request.

Overview
About this equipment
The high-capacity Spiral Separator efficiently separates round grains (like mustard, peas) from flat or broken materials (such as wheat husk and split grains) using gravity and centrifugal force. Ideal for sorting and cleaning operations in grain mandis, agri-processing units, and storage facilities.
