VSI Series vertical Shaft Sand Makers are commonly known as impact crushers and sharpers.VSI sand makers are the fourth generation of high-performance sand-making machines developed by ROCK BULLS which are based on advanced German technology and after analyzing many years of domestic mining activities. Our sand makers are equipped with an original thin oil lubrication station which uses double oil pumps to guarantee a non-stop supply of oil. They will automatically shut down when there is no oil flow or oil pressure. Oil cooling and heating devices guarantee that bearing lubrication will always be at optimum levels with the main shaft bearing maintaining a constant temperature to avoid overheating.

To make maintenance and parts replacement easier, we have done away with the traditional laggard cover opening modes of hoisting and using a manual jack and have introduced a semi-automatic hydraulic system. Users only need to press a button to open the top cover of the unit in order to carry out various maintenance procedures which greatly reduces the amount of manual labour required. This saves money and greatly increases service efficiency.
