2. What is your material to be crushed?
To crush large stones, you can either directly choose a hammer crusher or choose a two-stage crushing process consisting of a jaw crusher and a sand making machine.
To crush stones with high moisture content, choose compound crushers or roller crushers.
To crush medium-hard or soft stones, choose roll crushers, hammer crushers, or compound crushers.
VSI sand crushers and HVI sand crushers are suitable for stones of various hardness.
-
3. What are your capacity and finished product requirements?
If your sand making plant requires high output and good sand shape, buy a VSI sand crusher, an HVI sand crusher, or a mobile crushing machine.
If the sand making plant requires higher output, a hammer crusher can be purchased. But the sand grain shape is not very good.
For small sand making plants, roller crushers and compound crushers are good choices.
The above six types of sand crushers are the core equipment for sand making.
