由中信重型机械公司研制的内蒙古元宝山露天煤矿1400m3／h半移动破碎站，其核心设备是ZPGC－1370双齿辊破碎机。该破碎机进料粒度可达1500mm，出料粒度小于300mm，破碎物料强度可达150MPa。作为初碎机的双齿辊破碎机与其它形式的破碎机相比较，其最大优点是体积小，结构紧凑，
The 1400m3 / h semi-mobile crushing plant in Inner Mongolia Yuanbaoshan open-pit coal mine, developed by CITIC Heavy Machinery Company, has a core equipment of ZPGC-1370 double-roll crusher. The crusher feed size up to 1500mm, the discharge size of less than 300mm, broken material strength up to 150MPa. As the first crusher double gear roller crusher compared with other forms of crusher, its biggest advantage is small size, compact structure,
