Roller Mills HE-Serie

The new HE series Roller Mills are developed to crush or grind various materials, such as grain, oilseeds, biomass and others with an optimum result and low energy requirements.

Units are avaible in single, double, or triple high options. Each level contains two large, independently driven rollers to ensure an even flow to each stage. The large-scale axially riffled rollers rotate at the same speed in opposite direction to reduce pellets to a crumble of desired size

One top unit

The top unit consists of a continuously adjustable-speed rotating feeder which can rotate in two directions and the larger crushing rolls below. One rotating direction of the feeder is to the two solid-Hartguss breaker rolls. The opposite direction is the bypass function for products that do not require any further size reduction. The breaker rolls are independently driven by a belt drive. Roll speed is measured by speed sensors on each roll. Roll gap adjustment to 0.004″ is acheivable through manual adjustment or to 0.0004″ by automatic adjustment (optional).

One or two extra crushing units

The top unit can be extended with one or two extra crushing units, each of which consists of two solid-Hartguss breaker rolls. This ensures an optimum size reduction result.
