Hammer mill with automatic screen exchange
Optimize your milling operations with a high-speed solution that ensures seamless sifter changes, reducing downtime and manpower while maintaining consistent product quality in demanding production environments.

Grinds and Screens Powders and Granules
The Hamex Automatic Screen Exchange Hammer Mill by Dinnissen is an advanced grinding solution for processing grains, sugars, and minerals. It features a fully automated screen exchange system, allowing continuous operation without manual intervention. Capable of handling powders and granules in industries such as food, pharma, and chemicals, it offers adjustable rotor speeds with frequency control for precise grinding outcomes ranging from 150 microns to 3 mm. This hammer mill supports high-speed operation up to 1800 rpm while maintaining energy efficiency by utilizing a variable-speed motor. It includes options for a stone collector and magnet to enhance product purity, and its robust construction ensures long service life with minimal maintenance.
