Abstract
The grinding process plays a crucial role in various industries, including mining, cement, chemical, and food production. Despite technological advancements, existing milling technologies often face challenges related to energy consumption, component wear, and process control complexity. This study explores innovative approaches to improve mill designs, focusing on vibratory and ball mills with novel structural enhancements. A patent-based review was conducted to analyze different technical solutions aimed at optimizing grinding efficiency. A key innovation discussed is the introduction of an inclined-angle grinding chamber, which facilitates complex motion of grinding bodies, increasing impact directions on material particles. Additionally, vibratory mills with independent unbalanced drives were examined for their ability to enhance grinding chamber oscillations and increase productivity. However, these designs do not ensure counter-motion of grinding bodies, which is critical for maximizing impact energy. To address this gap, a new mill design is proposed, featuring a V-shaped grinding chamber combined with a vibration drive to induce counter-collision of grinding balls. This configuration significantly enhances impact energy and grinding efficiency. The proposed solution integrates all effective grinding principles, offering a novel approach to achieving superior material processing performance. Further experimental validation is recommended to confirm its advantages over existing designs.
