Crushing (or any other physical manipulation of) any substance is, by definition, a physical change. However, those physical changes can affect the conditions for a chemical change, potentially causing a noticeable change in the rate of said reaction.
Minyu Impact Crushers are designed with an extra large feed opening, hydraulic hood opening, and automatic adjustment control. Due to simple structure, low power consumption, high crushing ratio, and even grain distribution, our Impact Crushers have a wide application in multiple fields.
