Alexanderwerk GmbH

The Alexanderwerk PP 150 C is especially designed as a machine which meets the highest requirements and standards of the chemical industry. As the smallest Alexanderwerk model for the chemical sector it provides a roller diameter of 150 mm and a roller width of 75 mm. With a throughput up to 400 kg/h the PP 150 C can be used in a test center, for the research and development as well as for the production.

Through the double sided bearing of the rollers and a robust construction a maximum pressure force of 30kN/cm can be assured. Moreover, previously determined process parameters can easily be scaled up to larger production machines of the Alexanderwerk PP and WP machine series. Because of its modular design, great flexibility as well as adaptability to different granule sizes is guaranteed.

The basic machine, consisting of feed system and compaction rollers, can be provided either without a crushing step, with a single rotor fine granulator RFG 150 DS or with two rotor fine granulators RFG 150 DS. If required, a later upgrade is possible at any time. To ensure a compact design, the control system, control cabinet including hydraulics, vacuum pump, cooling water and air distribution system as well as the interface are all integrated into the machine.

The concept and construction of the PP 150 C is orientated on the requirements of chemical industry and provides the following advantages:

• double sided roller bearing to achieve the maximum pressure force
• hinged clam-shell-design for an easy roller removal and maintenance (1)
• product contacting parts are made completely of high-quality stainless steel
• equipped as standard with the patented Combi-Vent-Feeder®
• extendable feed system on a rotary table for easier cleaning (2)
• feed unit with vacuum design as standard
• 4-drive-technology for rollers
• automated PLC
• circumferential side seals
• easy and accurate scale-up

Options:

• integrated one-stage or two-stage rotor fine granulators in Diagonal-Design®
• rotor fine granulators on separate extendable drive rail (3)
• additional roller surfaces (smooth/grooved/knurled/squared)
• pressurized cooling for rollers
• hopper with level-limit switch
• substructure available in high-quality stainless steel
• scoop for manual raw material feeding
• Ex-execution according to ATEX
• static flake crusher for reducing the flake
• roller gap measurement
• roller gap control
• pneumatic conveyer for raw material/final granule
• integration with and/or enlargement to a plant concept
• complex control system with batch operation (possibility of data transmission

The PGS 165 A has been developed by Alexanderwerk as a detachable unit to a universal drive motor of the UM series. The rotor fine granulator is designed to meet the requirements and standards in the pharmaceutical, chemical and primary industry and is made for grating, shredding, crushing, desaglomerating, granulating of solid dry or humid substances.

The UM universal drive motor has an integrated quick release coupling via which a variety of slip-on attachments can be mounted on the UM. Such attachments may be optionally the rotor fine granulator RFG 150 DA or the grater/ shredder PGS 165 A.

Depending on the raw material and grating or shredding cylinder, the throughput can be as high as 1,000 kg/h. Grating and shredding cylinder with bores are available to achieve different granule geometries. Moreover, the mobile design provides great flexibility during granulation and allows an easy maintenance.

The RFG 150 DA has been developed by Alexanderwerk as a slip-on attachment to a universal drive motor of the UM series. The rotor fine granulator is designed to meet the requirements and standards in the pharmaceutical, chemical and primary industry and is made for granulation of dry or slightly moist substances.

The UM universal drive motor has an integrated quick release coupling via which a variety of slip-on attachments can be mounted on the UM. Such attachments may be optionally the grater/shredder PGS 165 A or the rotor fine granulator RFG 150 DA.

Depending on the raw material and screen basket, the throughput can be as high as 600 kg/h. Screen baskets with mesh sizes from 0.63 mm to 3.15 mm are available to achieve different granule geometries.

In comparison Alexanderwerk has developed a patented granulator in Diagonal-Design®, which raises the capacity up to 100 % by increasing the effectiveness of the working area of the screen. This leads to a doubling of throughput and in turn to a very gentle with minimal fines generation. Additionally production costs are reduced and the quality of the final product is increased. In addition, the mobile design provides great flexibility during compaction and allows an easy maintenance

With the introduction of the WP 120 Pharma, Alexanderwerk offers a roller compactor designed to meet the highest requirements and standards in pharmaceutical research and development. On this machine small amounts of as little as 5 g to a maximum up to 40 kg/h (Lactose) can be processed with the standard roller width of 40 mm into granulates of varying sizes.

This enables realistic and fully controlled production conditions when processing special products, producing small batches in laboratory or at the lower production levels. Because of its modular design, the process technology can be almost completely disassembled without special tools. Due to its canter lever bearing design the rollers can be easily cleaned or replaced. The mobile design provides great flexibility during compaction feasibility studies and allows an easy maintenance. The WP 120 Pharma is designed to meet cGMP and its mobility is ensured due to its compact design and fully integrated control and operator panel. Moreover, previously determined process parameters can easily be scaled up to larger production machines.

The design and construction are orientated on the strict requirements of pharmaceutical industry and provide the following advantages:

• cGMP design consistent separation between process material and technical equipment
• Rollers in cantilever design integrated two-stage rotor fine granulators in Diagonal-Design® made completely of high quality stainless steel, non-metallic parts FDA approved
• Automated PLC
• URS-conformity as required
• Tool free disassembly
• Easy and accurate Scale-up mobile machine base

• circumferential side seals WIP (Wash in Place) 21 CFR Part 11
• containment solution with isolator technology
• additional roller surface (smooth/grooved/knurled/squared or a desired combination)
• pressure water cooling
• hopper with level limit switch
• pneumatic conveyor for raw material/final granule
