The double roller mills are equipped with smooth rollers as standard, which limits the maximum particle size due to the frictional intake conditions. To improve the feed conditions, profiled rollers are required, which we can also offer. The double roller mill can usually achieve a comminution ratio of 1:2 … 1:5 up to a maximum of 1:20.
An infinitely adjustable roller gap
One of the two rollers is rigidly arranged, the second roller can be adjusted manually, motorized or hydraulically via a spindle. The set roller distance can be read off a scale or recorded digitally via a sensor.
A reversible overload protection
Spring assemblies allow the movable roller to evade smaller, non-breakable materials.
High force transmission into the movable crushing roller
by mounting them on a rocker, high compressive forces can be generated in the roller gap.
Low-wear/low-contamination Crushing & Milling with crushing rollers made of
Cast steel, tungsten carbide or all-ceramic
