Product catalog summary
Introduction
Cormall has been developing straw handling equipment since the 1970s, continuously improving technology for stable and durable machinery utility. The company offers automatic string removal and advanced separation systems for efficient straw processing.
Obstacles and Solutions
Primary traps separate larger stones and wood parts, while secondary traps handle denser materials. Challenges in older systems included stones and steel breaking shredder knives, and strings tangling around rotors. The new system addresses these issues with improved design and technology.
Demands and Capabilities
Cormall supports various processing demands, offering dust-free, node-free, or powdered straw. The hammer mill enhances straw absorbency by crushing nodes and opening tubes. The system can handle straw in full length or shredded, with 80% of material below 60 mm after shredding.
Comparison: Shredder vs. Bale Breaker
The shredder rotor operates at 3000 RPM with 2x 30 kW power, handling 6-7 tons/hour, while the bale breaker augers operate at 60 RPM with 2x 15 kW power, handling 8-12 tons/hour. The shredder is noisier (80-90 dB) compared to the bale breaker (50-60 dB).
Applications
Straw processing technologies offer diverse applications, including building materials (chipboards, insulation panels), fuel (pelleting, briquettes), biological processes (mushroom production, bioethanol, biogas), bedding materials, packing materials, animal feed, and waste processing.
Technical Specifications
The system processes round, square, or loose straw bales with automatic line feeding and string removal. Capacities range from 250 kg to over 30,000 kg/hour, with moisture content managed between 15% and 20%. Dust extraction options vary, with emissions below 5 mg/Nm3.
Conclusion
Cormall offers comprehensive support for straw processing needs, including layout drawings and customized solutions to meet specific requirements.

Obstacles Cormall has been involved with the development and engineering of straw handling equipment since the early 1970's. All through the period we have improved our technologies to ensure the stable and durable utility of our machinery. Long steel parts after primary trap Bigger stones are separated at the primary trap and from here transported with auger to secondary trap. Automatic string removal can be supplied. Long wood part after primary trap The secondary trap is placed at the end of mechanical transport and before pneumatic transport of the straw. All material with higher density...

Straw shredder verses bale breaker RPM Power installed Capacities Max production Noise dB Moist percentages: The new system can have 2-3 straw bales inside the machine, thus making a average moist percentage in a continues flow rather than a batch. Bale breaker augers Obstacles challenge in the old system: Stones and steel breaking the shredder knifes Strings/twines tangling and packing arround the shredding rotor Plastic strings melting onto bearing and aksel shafts.
