Box-type breaker introduction
The box-type breaker is also called box-type hammer crusher. It increases the feeding space on the basis of the original hammer crusher. The new type hammer crusher can crush edge length 450-1400mm material into a 120mm size ore powder, but doesn’t plugging. The box-type breaker can be used as a secondary crushing, is mainly used in mining, cement, building materials, chemicals and other industries. Box-type breaker uses to crush the materials such aslimestone, rock, gypsum, coal and gangue that the compressive strength not up to 200MPA. Besides the box-type breaker is necessaryequipment for crushing stones. Box-type breaker is an improved product to hammer crusher, when the raw material revolves, the material is counterattacked or hammer blow in the crushing cavity, and against each other, increasing the staying time of raw material, making more raw powders. The box-type breaker is especially suitable for broking the powder materials, such as coal shale, limestone, gypsum etc.
Working principle of box-type breaker
Stone material directly enters into high-speed rotating turntable through the top of machine, at the action of high-speed centrifugal force, engendering high velocity impact and high density crush. After hitting with each other, stone material forms vortex motion between turntable and casing, then through hitting, rubbing and crushing with each other repeatedly, until the requested…
