The VSI 7A series impact sand maker with deep cavity is a new generation product that not only draws on the advanced technology of similar products at home and abroad, but also has a number of independent research and development results. In the application of large and super large machine-made sand and fine aggregate production lines, it has demonstrated extremely powerful performance.
The VSI 7A series impact sand maker with deep cavity is also suitable for applications in the fields of metal/non-metal ore, metallurgical slag,and material recovery. VSI7A series sand making machines provide high-quality aggregates with more reasonable gradation and better grain shape to meet high-quality specifications.
By adjusting the hopper feeding device, can easily switch between the two modes of "falling feeding + center feeding" and "full center feeding". Adjusting the angle of the distribution plate can avoid the direct impact of the material on the impeller and reduce the abnormal wear of the impeller.
The design of the large discharge port makes the material unloading more smoothly, which effectively prevents material blockage, avoids abnormal damage to the equipment, and improves the crushing efficiency.
The adoption of new technology and new materials greatly prolongs the service life of wearing parts and effectively reduces downtime and maintenance time and wear of wearing parts.
The modular design of the main shaft assembly,thin oil lubrication and grease lubrication; a combination of multiple sealing forms is designed, and the sealing effect is more reliable.
