A team of scientists from Voronezh State University of Engineering Technologies (VSUET), in collaboration with specialists from the Voronezh Scientific and Production Center of Feed Industry, has developed and patented a groundbreaking hammer mill that promises to transform grain processing operations. This innovative design specifically addresses common deficiencies in existing crushers, which often feature complex designs, rapid wear rates, and inconsistent particle size distribution—factors that significantly impact processing efficiency and product quality in both feed and grain processing industries.
The new crusher’s revolutionary design incorporates several key improvements. According to Professor Igor Bogomolov, one of the developers, the machine features “a rotor mounted on bearing supports with discs containing radially made slots, where axes with wing-shaped hammers are hinged.” The innovative arrangement includes diametrically opposite wing directions for even and odd hammers, complemented by corrugated hollow sleeves with internal springs and replaceable flexible mesh with stamped holes in the lower part of the side covers. This sophisticated engineering solution optimizes energy consumption during crushing while ensuring effective classification by dispersion of the already crushed product.
The technological advancement comes at a critical time for the global grain processing industry. According to a 2024 report by the International Feed Industry Federation, equipment efficiency and energy consumption represent two of the most significant operational challenges, accounting for approximately 30-40% of total processing costs. The global hammer mill market, valued at $985.2 million in 2024, is projected to grow to $1.3 billion by 2029, driven by increasing demand for efficient processing equipment in both human food and animal feed sectors.
The Voronezh team’s innovation addresses multiple industry challenges simultaneously:
- Adjustable productivity allowing operators to optimize output for different grains
- Enhanced wear resistance of working surfaces, addressing a key maintenance issue
- Consistent particle size distribution, crucial for both feed digestibility and industrial applications
- Reduced energy consumption through optimized mechanical design
The development has already attracted interest from Russian processing equipment manufacturers and has been implemented in production. This rapid adoption reflects the practical utility of the innovation and its potential to improve operational efficiency in grain processing facilities.
The Voronezh hammer mill represents a significant advancement in grain processing technology, addressing long-standing challenges in equipment performance, maintenance costs, and product consistency. This innovation demonstrates how targeted engineering solutions can yield substantial improvements in agricultural processing efficiency. For farmers, feed producers, and grain processors, this development offers the potential for reduced operating costs, improved product quality, and greater flexibility in processing various grains. As the global agricultural industry continues to seek efficiency improvements and sustainability enhancements, such technological innovations will play an increasingly important role in maintaining competitive advantage and meeting the growing demand for processed grain products.
