As a widely used secondary crushing equipment, the impact crusher has always been the main component of mining machinery and is welcomed by users for its simple structure and lower price. At present, the mainstream impact rock crusher machine products in the domestic market are traditional and European impact rock crushers.
- Cover opening device
Traditional impact rock crusher: screw rod opening device, manual screwing of the nut, time-consuming and labor-intensive.
European version impact rock crusher machine: hydraulic jacking device, easy replacement of wearing parts, more convenient maintenance.
- The differences between the hammer
Traditional: old-fashioned straight bar hammer
European version: “Crescent” round arc hammer. The crescent-shaped plate hammer is better, which can guarantee the vertical impact of the material, the impact force is large, and the crushing efficiency is high; the impact surface is also larger and more durable than the linear plate hammer.
Different from the mobile rock crusher machine, under the action of centrifugal force, the wedge fixing method can ensure the rotor speed faster, the hammer stronger, and more reliable working condition. This is a better way of fixing the hammer. Most manufacturers generally use this method. Generally, crescent-shaped plate hammers are mostly fixed by wedges, while straight plate-shaped hammers are usually fixed by pressure blocks.
