The B Series Deep Rotor VSI Crusher is used as a core sand-making and shaping machine across mineral processing, cement, aggregate, glass raw materials, and metallurgical applications. It is suited for processing materials such as iron ore, non-ferrous metal ores, quartz sand, basalt, bauxite, corundum, and other medium to hard rock materials where consistent particle shape and controlled gradation are required.
The crusher operates using a deep-cavity rotor that accelerates material and applies impact energy through multiple crushing modes, including material-on-material, material-on-iron, and peripheral impact. Feed material enters the rotor, is propelled at high speed, and fractures upon impact, producing well-shaped particles with reduced internal stress. Adjustable feeding configurations allow operators to balance throughput and product quality.
This design improves throughput while maintaining efficient energy use and controlled wear. Modular wear components allow replacement of only worn parts, reducing downtime and operating cost. Optimized internal flow paths help minimize resistance and improve material pass-through, supporting stable production under continuous operation.
The B Series Deep Rotor VSI Crusher is a strong fit for producers focused on manufactured sand, aggregate shaping, and fine crushing in stationary or mobile plants. It is commonly selected where flexibility, durability, and consistent output are priorities across a range of feed materials.
Model selection is based on maximum feeding size, target capacity in tons per hour (TPH), rotor speed in revolutions per minute (RPM), installed power, and overall machine dimensions. The technical data below outlines these parameters to support proper equipment selection.
Bros Dirt Diggers can assist with sizing, configuration, and integration of the B Series Deep Rotor VSI Crusher to match your material characteristics and production goals.
This table shows maximum feeding size, throughput capacity, rotor speed, installed power, and overall dimensions for each B Series Deep Rotor VSI Crusher model.
