China Vertical Shaft Impact Crusher - Composite Crusher Suppliers at Leading Factory for Sand Making Production
Working Principle
The main components of vertical shaft crushing equipment include the rotor, hammer, liner, feeding mouth, discharging port and electric motor. Materials fall into the high-speed rotation impellers from the feeding mouth of the machine. Under the high-speed centrifugal force, materials will have high-speed impact with other materials which flow around the impellers. After they attack each other, they will be discharged from the bottom discharging mouth. Materials will experience repetitive crushing before being discharged. Besides, it can achieve the required product size by controlling screening equipment.

Frequently Asked Questions
How does the vertical shaft crushing equipment work?
Materials are fed into high-speed rotating impellers where centrifugal force flings them to impact other surrounding materials. This rock-on-rock collision provides highly efficient, repetitive crushing before the finished material is discharged through the bottom outlet.
What is the typical output size for the PFL series crushers?
The standard output size for all PFL series models ranges from 0 to 5 mm, making it ideal for fine crushing and sand making applications.
How can I control the final product size?
The final product size can be precisely adjusted and maintained by controlling downstream screening equipment, which recirculates oversized materials back into the crusher.
What is the production capacity range of these vertical shaft crushers?
Depending on the model, capacity ranges from 5-15 t/h for the PFL-800 up to 40-100 t/h for the largest PFL-1750 model.
What are the main components inside the crushing chamber?
The internal chamber mainly consists of a high-speed rotor, heavy-duty hammers, and wear-resistant liners that work together to impact and crush incoming materials.
