Pelletizing systems

Underwater pelletizing system for spring pelletizers - M-USG

The M-USG underwater pelletization system has been producing virgin polymers worldwide for decades. The extremely flexible system guarantees a high level of system availability, especially during continuous operation, and meets the highest quality requirements for cylindrical pellets.

In the past, glass fiber compounds were usually produced by strand pelletizing. Recently, however, there has been a clear trend toward underwater pelleting. Wear resistance and optimized machine concepts have shown that high throughput rates and low wear costs are possible for glass fiber compounds from underwater pelletizing systems.

Low Waste Continuous Production

The LWCP System concept was designed to allow the user to operate the production waste recycling machine on a continuous basis and to increase output without interruptions from a defined minimum throughput up to the maximum line throughput. 

Pellet Rates up to 500 kg/h

Gala’s COMPACT LAB SYSTEM, a underwater pelletizing system is used downstream of an extruder or gear pump for polymer production. Used in laboratory settings and by compounders when underwater pelletizing processes and drying samples of polyethylene, polypropylene, polystyrene, ABS, flexible PVC and other polymers.

The objective of the Flexline System for underwater pelletizing processes: The Flexline machine concept for underwater pellitizing systems is a logical extension of Gala technology. The machine concept permits complex product changes within a matter of minutes to minimize unproductive time for polymer and compound manufacturers.

For pellet rates up to 1.500 kg/h, (depending on equipment configuration and polymers)

A value engineered underwater pelletizing system and underwater pelletizing process designed to economically pelletize and dry thermoplastics—polyethylene, polypropylene, polystyrene, rigid PVC, flexible PVC, and more—for polymer production at throughput rates of up to 1,500 kg/h (3307 lbs/hr.)

Underwater pelletizing systems for highly profitable throughput rates of up to 36,000 kg per hour

The SPHERO® underwater pelletizing system has been particularly designed to process thermoplastics and produces spherical pellets. This most flexible system for underwater cutting is applied in the production of raw materials, compounds, masterbatches, engineering plastics, recyclate, organic and wood polymer composites, thermoplastics elastomers, microgranulate, hot-melt adhesives, and more.

Spring-Loaded Pelletizer

The Spring Loaded Cutter (SLC) is a cost efficient solution for underwater pelletizing basic polymers at lower rates. The SLC pelletizer uses constant spring pressure to adjust the cutter blades to the die plate, reducing the need for operator attention and underwater cutting. The cutter hub is connected to the motor shaft through a telescoping spring sleeve, and the blades are automatically positioned against the die plate using spring force. The blade force can be adjusted per application or product by simply changing springs.

Advanced, cost-effective underwater pelletizing technology

ZHULI® is an underwater pelletizing system with integrated pellet dryer and process water handling, designed to process a wide range of polymers and thermoplastics. The efficient system is characterized by high flexibility and small footprint. ZHULI® is manufactured locally with key components made in Germany. With an installed base of more than 9,000 underwater pelletizing systems, we help our customers to achieve the maximum level of profitability.

Electronically Adjustable Pelletizer

The EAC pelletizer for underwater pelletizing offers fully automated control of blade adjustment, positioning, and monitoring, resulting in maximum blade and die face life. Monitoring and adjustment processes are programmed in the Gala PLC controlled system. An optional integrated blade position measuring system for unterwater pelletizer is available, providing indication of blade position and warning of the need for a blade change.

Manually Adjustable Pelletizer

The Manually Adjustable Pelletizer (MAP), a underwater pelletizing application, features a manual adjusting wheel to position the blades against the die plate. This simple blade adjustment design of the underwater pelletizer provides visual blade wear indication and maximum control of blade position. The unique design of the axial advance system replaces the need for a bearing housing assembly. The MAP design requires only one long life thrust bearing for accurate adjustments.

Pellet Processing Systems for the Plastics Industry

Gala’s LPU® Laboratory Underwater Pelletizing System is specifically designed for laboratory developmental work, market sampling, and light pellet production on materials such as PE, PP, ABS, PA 6, PA 6.6, PET, PBT, PPO, and more. The system is designed for pelletizing rates up to 100 kg/h (20–220 lbs/hr), depending on the material for underwater pelletizing processes.
