The Difference Between VSI Sand Making Machine And Impact Crusher

There are significant differences between VSI sand making machines and impact crushers in multiple aspects. The following is a detailed comparison of these two types of equipment:

Working principle:

VSI sand making machine: adopts the operating principles of “stone to stone” and “stone to iron”. Under the action of the high-speed rotating rotor driven by the motor, the large raw materials are accelerated by centrifugal force and collided with another part of the material, which is then subjected to multiple impacts, friction, and crushing grinding in the eddy current crushing chamber, ultimately completing the sand making process.

Impact crusher: generates strong impact force and crushing effect through high-speed rotating rotor and impact plate, crushing materials into the required particle size. The material is hit by a plate hammer in the crushing chamber, and then it is thrown at high speed towards the impact plate for further crushing. Finally, the material is discharged from the impact plate through the gap between the rotor, star wheel, and body lining plate.

Function and features:

VSI sand making machine: It has the functions of fine crushing and coarse grinding, as well as stone shaping. After sand making, the finished product has a very good particle shape, no cracks or tension, and the content of needle like materials is low. This equipment has high production capacity, good product particle shape, high crushing efficiency, and low energy consumption, making it particularly suitable for manual sand making and stone shaping.

Impact crusher: With a sturdy structure, it has high compressive strength and wear resistance, and can handle materials of various hardness and strength. High crushing efficiency, low energy consumption, uniform product particle size, strong adaptability, suitable for crushing various materials.

Structure and composition:

VSI sand making machine: mainly composed of seven parts: feeding hopper, distributor, eddy current crushing chamber, impeller body, main shaft assembly, base, transmission device, and motor.

Impact crusher: mainly composed of rotor, impact plate, frame, transmission device, feed port, discharge port, and other parts.

Application field:

VSI sand making machine: specialized in providing high-quality sand and gravel aggregates for highway and railway, construction, hydropower dam construction, and concrete mixing plants.

Counterattack crusher: suitable for crushing processes in multiple industries such as mining, construction, metallurgy, and chemical industry, such as ore, construction waste, limestone, quartz sand, etc.

In summary, There are significant differences between VSI sand making machines and impact crushers in terms of working principles, functions and characteristics, structure and composition, and application fields. VSI sand making machines focus more on sand making and stone shaping, while impact crushers focus more on crushing materials of various hardness and strength. When selecting equipment, comprehensive consideration should be given to specific production needs and material characteristics.
