I would like to use an Impact Crusher to reduce the size of clinker and limestone material to 3mm. So, I have a few questions before placing my order: 1. Does your Impact Crusher achieve a discharge size of 3mm for clinker and limestone? 2. How many tons per hour can it produce if the discharge size is 3mm? 3. What is the lifespan of spare parts such as racks? 4. How many working hours can the racks be used? I am looking forward to hearing from you. Regards, WhatsApp:...
