Roller Compactor PP 250

Economic Compaction up to 4.000 kg/h

Alexanderwerk’s PP 250 is currently the best roller compactor available for the economic compaction of raw materials, with a throughput of up to 4,000?kg/hr.

Alexanderwerk has been developing and producing roller compactors for the chemical and natural resources industries since the 1950s. The PP-Types are a completely new generation of heavy-duty roller compactors developed from our long-standing experience and incorporates the latest process enhancements.

To achieve a high compacting output each of the two rollers inside the compacting unit, mounted between bearings, are driven by two gear motors on either side, left and right. This unique design guarantees high energy and torque input to the rollers allowing the higher circumferential speeds usually generated by larger roller diameters. The required high material flow is fed to the vertical rollers via the Combi-Vent-Feeder® System patented by Alexanderwerk, included as standard. Moreover, the feed unit is enhanced by the included vacuum design that significantly improves the conveying characteristics and resultant increased throughput.

The machine’s design and construction meets all the requirements of the chemical and natural resources industries:

- Clamshell design, improved accessability

- Extensive use of standard components for high machine availability

- Compact design

- Symmetry in parts and weight

- Machine upper section pivotable

- Patented Combi-Vent-Feeder® System as standard

- Feed unit in vacuum design as standard

- Each Roller is driven by two gear motors

- Various roller widths with adjusted number of screws, available

- verschiedene Walzenbreiten mit angepasster Schneckenanzahl

- Optional: Wash in Place (WIP)

- Optional: All stainless steel construction

- Optional: explosion-proof acc. to ATEX

- Optional: Utility cabinet (vacuum pump, water cooling system, air/gas supply, hydraulic)

Applications

Roller compactors manufactured by Alexanderwerk have been successfully used for years in the chemical and natural resources industries in the production of organic and anorganic raw materials such as:

- Pigments

- Battery substance

- Salt (de-icing salt, salt for water softening)

- Fertilizers

- Silicid acid (for the further processing of tyres)

- Animal feeds

- Additives (softening agents, for example)
