What is Asphalt Pulverizer?
In asphalt milling, only the top surface layer of asphalt is removed in preparation for a new overlay of asphalt. The top removed layer is recycled into other asphalt products, but the bottom base layer is left intact. During pulverization, both the top layer and underlying stone and aggregate are ground up but reused for the new asphalt.

Characteristics of open- and closed-circuit grinding systems
Abstract. The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
