Vertical Shaft Impact P-B Series

The Weierde P-B series Vertical Shaft Impact (VSI) crusher adopts the rock-on-rock impact crushing working principle and has become synonymous with high-quality products in the quarrying and mineral processing industries.

Proven model for optimal product quality

The Weierde VSI crusher is unique due to its crushing process. Most types of crushing use metal parts to crush rock, while the Weierde VSI utilizes the feed material inside the crusher to impact and crush itself. This rock-on-rock working principle is the lowest-cost method among all impact crushing methods. The high-speed impact crushing in the Weierde VSI crusher improves material density, enhances particle shape, and produces the highest-quality products on today's market. It is well known that the better the particle shape of aggregate products, the higher the performance of concrete, asphalt, and base course mixtures.

The Weierde VSI crusher is commonly used in the final crushing circuit. In the widely applied quarrying and construction industries, thousands of Weierde VSI crushers are operating efficiently around the world. They can also be applied in manufactured sand, grinding feed, industrial mineral processing, and recycling. This is all thanks to their unique free-impact crushing and grinding action, their ability to handle fine powders, and the ability to fine-tune crusher performance by simply changing the rotor speed or the cascade flow ratio.

Key to success

The updated design of the Weierde VSI rotor maximizes the service life of wear parts and improves equipment uptime by reducing component replacement time. The Deep Chamber Rotor (DTR) technology enables higher output with lower power consumption.

Genuine Weierde high-quality parts ensure trouble-free operation. Proper component materials and profiles guarantee a longer crusher service life.

Multi-stage crushing optimizes product quality

The feed material first enters the rotor and is accelerated to 80 m/s (262 ft/s) before being discharged from the crushing chamber. In addition, material can bypass the rotor and overflow into the crushing chamber. This cascade feature allows operators to optimize output and power consumption and to control product gradation and shape to meet all technical specifications.

Simple to use with minimal maintenance downtime

The Weierde P-B series VSI crusher is designed with installation convenience in mind. Due to low static and dynamic forces during operation, foundation requirements are low.

Safe and convenient rotor component access doors greatly reduce maintenance downtime. Custom lifting devices and rotor turning arms replace additional lifting equipment typically used for general maintenance, and facilitate internal inspection and quick rotor replacement. A simple and reliable automatic lubrication system performs routine grease lubrication of the main shaft. The Weierde IC crusher automation system ensures safe operation and condition monitoring.
