applicationf the crusher can be used to crush ores and rocks whose grain size is smaller than 340mm. it can be widely used in small and medium mine, building material, highway engineering, silicate and chemical industry. it can crush the materials whose compressive strength is less than 320mpa. working principle: the electric motor transmits power through belt, drives the moving jaw plate do periodic movement to the fixed jaw plate surround the eccentric shaft. the angle between toggle plate and moving jaw plate enlarges when the moving jaw plate moves up. so the moving jaw plate is closes to the fixed jaw plate. the stuff will be crushed in this process. the angle between toggle plate and moving jaw plate decreases when the moving jaw plate moves down. the moving jaw plate moves away from fixed jaw plate by the pulling of rod and spring. the products such as stone after be crushed will be discharged from the outlet. features: large crushing ratio; even granularity; simple structure; reliable operation; easy maintenance; low expense. tel: 0086-371-65948911 fax: 0086-371-65948723 mobile: 0086-15937120225 email: zzdschyy@163.com contact person: linda chen msn: dingshengchyy@hotmail.com
