Why you put two crushers?
The blades of crusher need to be grinded after a period of crushing. For 24 hours non-stop running of whole line, one crusher is installed for crushing and another is for standby. But if the client has budget concern, one crusher is also available for normal operation. The only disadvantage is that the client needs to exchange the blades every 40 tons of production. And the line should be shut down during blade exchanging.
