Glass Crushing Mills

Glass crushing mills are very similar to stone or rock crushers with certain differences keeping in mind the properties of glass. The two methods used for glass crushing are abrasion and impact. Abrasion involves crushing by friction with equipment like jaw or cone crusher and impact crushers include hammer mills and rotating drums.

Glass is highly abrasive in nature. It is lightweight and bounces on impact rather than break and when they do, they break into angular elements. Because of these properties of glass, impact-crushing equipment is preferred over abrasion as it provides greater durability and uniform shape. They are generally smaller than rock crushers.

Common Glass Crushing Equipment:

Rotating drums have bars attached on the outside of the spinning drum that sling the glass at the breaker plate. The space between the bars and the breaker plate regulate the particle size.

Hammer mills have a rotating shaft with free-swinging hammers. It propels the glass to the chamber sides. Very fine particles can be attained by this method.

Vertical Shaft Impactor (VSI) – Glass is hurled against the impact plates. And this continuous process crushes the glass. The velocity and the geometry of the thrower regulate the particle size.

Horizontal Shaft Impactor is also called and impact crusher. It uses a continuous breaker bar mounted horizontally in the rotor. Glass is thrown against one or two adjustable aprons
