Designed to grind brittle to hard products to a narrow particle size distribution with minimal dust content.

The 250.3 series of one- two- and three-stage roller mills offers:

• A continuous gap monitoring and adjustment system (patented)
• High throughput
• Dust-tight design
• Minimal mechanical impact and temperature increase of product
• Efficient energy initialization
• Low space requirement
• High durability of rolls
• Easy access to all machine components
• Easy roll exchange, low maintenance effort

• Automatic gap control during the operation of the machine including:

        – Zero gap adjustment of the roll gap
        – Automatic opening of the roll gap to working width
        – Roll wear compensation
        – Adjustment of the rolls for parallelity
        – Compensation of roll expansion due to thermal influences
