Screw compactors have two main purposes:

They can compact many different types of materials quickly and effectively, such as EPS, EPE and EPP packaging, plastic bottles, aluminium cans, and mineral wool. RUNI screw compactors are used across industries such as seafood, breweries, recycling etc.

They can also separate liquids from solids, for example removing water from washed plastics or dewatering dairy products, PET-bottles, alu cans, paint buckets and other liquid-containing waste.

Often, both functions are used at the same time. For example, RUNI screw compactors can empty and compact liquid-containing packaging such as juice cartons while separating the liquid from the packaging material.

Recycling machinery customized for the purpose

Runi Screw Compactors has a basic unit, which is available in three sizes and used in all machines. In addition, there are also standard or customized accessories, which make the machine particularly suitable for the specific job it performs.

The primary aim is always to customize the compactor to ensure it suits the customer's existing production facility as much as possible. At the heart of the machine is a hydraulic-automatic feed-control system, which ensures uniform compacting for all materials at all times without overloading the compactor.

Minimal handling

The large capacity of the screw compactor, and its slim-line design, make it well suited for locating directly in a process line or at the end of a production line to minimize handling. Start and stop can be controlled in many ways, either manually or automatically, using sensors. A fully automatic silo system with a heavy-duty pre-crusher and several large screw compactors can cope with enormous quantities without having an operator between the sorting and final compacting processes.

The great advantages of screw compactors:

• Optimum solutions based on RUNI’s pioneering work, development, and long experience
• Continuous compaction and dewatering of material
• High rate of compacting and dewatering because of high pressure
• Low energy consumption because of the torque of the screw
• Tough and user-friendly, built for hard work
• No heat is required to make staple EPS blocks; instead, the friction of the material is used, saving energy
