Hydraulic aggregate for mill PM 800

Hydropneumatic runner mill-stone pressure - hydraulic circuit function:

• Start of the mill - the runner mill-stonea are at the stop and the accumulators are pressurized to the required working pressure.
• Steady running of the mill - creat of permanent pressing force, allowing the springing of runner mill-stone and occasional turn away up to 25 mm.
• Possibility to increase or decrease the pressing force while running the mill in the range of approx. 20% from the set pressure.
• Lifting the runner mill-stone, reaching the upper position indicated by the end sensors (part of the mill).
• The hydraulic system ensures that the runner mill-stone are not spontaneously triggered in any position.
• Triggering of the stones to the take, breaking the stone. Upon reaching the layer of minced material, increasing the pressure force and compress the accumulators to the desired value.
• When the milling is complete, the pressure is relieved.
