The new PTN Roller Mill series HE is developed to break or structurize various materials, such as grains, oilseeds, biomass products and/or others. Herewith an optimum result and low energy requirements is achieved. An integrated rotating feeder in the top unit ensures an even flow to the breaking/structurizing rollers. The large diameter axially riffled breaking rollers rotate at the same speed in opposite directions. Using accurate measurement, the large 300 mm structurizing rollers guarantee smaller particles with minimum fines.
Top Unit
The top unit consists of a rotating feeder, to be controlled by a frequency converter, which can rotate in two directions. One rotating direction of the feeder is to the two breaking rollers. The opposite direction is the bypass function. Driven by electric motor, with V-belt transmission on the motor side. A double toothed timing belt connects both rollers on the other side. Sensor for speed control of structure roller transmission.
Extra Units
The top unit can be extended with one or two extra breaking/structurizing units, each consisting of two solid structurizing rollers. This ensures an optimum structurizing result.
Features
Integrated rotating feeder from mild steel with two rotating directions: › one direction to structurizing rollers. › opposite direction by-pass structurizing rollers.
Solid construction in mild steel.
Manual roller adjustment with adjustment accuracy 0.1 mm.
Solid structurizing rollers made of ‘Hartguss’ material (5 to 6 time longer lifetime than chrome steel).
Oil free transmission by means of double toothed timing belt.
Inlet and outlet with flange, inclusive counter flange.
Options
An electro-pneumatic operated bypass flap (in the double unit to bypass the lower unit, in the triple unit to respectively bypass the middle or lower unit).
Remote roller adjustment, with adjustment accuracy 0.01 mm.
