The Principle Behind the Screw Compactor

An Efficient Basic Mechanical Principle

The screw is the heart of all RUNI compactors. A basic mechanical principle that is just as apparent as it is efficient. A screw is used to convert the power of rotational movement into horizontal propulsion, which can provide great pressure due to its momentum.

We can find countless examples of this principle in our everyday life. We all know how the great force of a screw movement can be transferred to a bolt, a bench screw, or a meat mincer.

RUNI’s Robust Screw Compactor

The robust compactor from RUNI features a powerful metal screw that effectively crushes and transports the material to the end of the screw where a significant pressure is applied to ensure the crucial compaction.

Without a counter-pressure the screw would merely transport the material from the inlet to the exit of the machine. In RUNI’s machines this essential counter-pressure is provided by already compacted material, securely held in place by electronically controlled hydraulic jaws.

Once the machine is appropriately configured, the screw continues its operation, gradually pressing the compacted material through the jaws. This process ensures that the desired level of compaction is consistently achieved.

The Great Advantages of Screw Compacting 

  • Continuous compacting of material
    The screw compactor ensures a continuous process of material compaction, optimizing workflow efficiency and minimizing downtime.

  • A high degree of compaction due to high-pressure
    The very high pressure in our screw compactors guarantees a remarkable reduction in material volume.

  • Low energy consumption due to the moment of the screw
    By utilizing the moment of the screw for efficient compaction, our screw compactors minimize energy consumption.

  • No heat is added. Instead, the friction of the materials is utilized
    Unlike other compaction methods, our screw compactors do not add heat to the compaction process; instead, the friction among materials drives the compaction.
