ROCK BULLS MACHINERY

The VSI Series Vertical Shaft Sand Makers, referred to as impact crushers and shapers, are the fourth generation of high-performance sand-making machines developed by ROCK BULLS. These machines utilize advanced German technology and insights from years of domestic mining practices. They feature an original thin oil lubrication system with dual oil pumps to ensure a continuous oil, automatically shutting down if there is a lack of oil flow or pressure. Additionally, cooling and heating systems maintain optimal lubrication levels for the main shaft bearing, preventing overheating.

simplify maintenance and parts replacement, we have replaced traditional manual methods with a semi-automatic hydraulic system.
