I would like to enquire about limestone grinding mills for all models to explore the best options. Our requirements have shown below: 1.Input -Input material : Limestone -Hardness :  Between 3 and 4 on the Mohs Scale of Hardness -Particle size: 0-10 mm -Moisture content: 0.5-0.9% by average 2.Output Requirements        1. Product size: 50-200 mesh        2. Capacity: At least 20 tons per hour for producing 50 mesh We would like to explore all models that be able to produce even if it is beyond our requirements because we are also considering the flexibilities of machine to produce and expand the production in the future as well. Could you please send me the details of the grinding mill?
