Can Impact Sand Crushers Process River Pebbles for Sand Making?

Can impact sand making machines really be used to crush river pebbles into sand? Apart from checking whether the raw material meets the working conditions of the impact sand maker, we also need to see if the finished sand can satisfy customers’ requirements. Here is a detailed explanation:

1、 Failure to meet basic working conditions

Though impact sand makers can be used for sand production, they are only suitable for crushing medium-hard and brittle materials. River pebbles are totally different from ordinary stones. Their main component is silica, which has a Mohs hardness starting at 7. That’s why impact sand making machines are not an ideal choice for processing river pebbles into sand.

2、High cost if used reluctantly

Impact sand makers are not really fit for river pebble sand making. But if customers insist, it can barely finish the sand making work. However, the cost is very high. The rotor needs frequent replacement, leading to a high long-term operating cost.
