Advantages of counting vertical shaft impact crusher
The vertical shaft impact crusher is designed to rely on the sudden impact between the ore and the hard object like other impact equipment. Therefore, they have the same basic characteristics as other impact crushers, and their design is superior to the extrusion type. If the feed port is large enough, the mineral is crushed along the natural interface to obtain a high particle size crushing ratio and to produce shaped product particles. By natural crushing of iron ore crushing method may be crushed as forming gold metal particles.
The mineral material falls through the feeder into the mineral distributor, which distributes the material evenly between the guiding impellers. The impeller projects the material onto a metal surface that is fixed around the crushing chamber and is called an anvil. Each piece of anvil is fixed. The angle and distance are set according to the specific application in order to achieve the maximum breaking rate. The broken material falls into the discharge area, which is the basic working principle of the impact crusher.
In the ore-ore crushing plant, an ore lining is first formed in the rotor, and the rotor projects the material around the crushing cavity at a line speed of 85 m/sec to form a material layer. A lug device is provided in the crushing chamber so that the retained material has an angle of repose, and the broken material first moves upwards and then is discharged from the rotor through the material flow. Therefore, the ore-ore crusher achieves material breakage by mutual friction, abrasion and impact between the ores. The particle size ratio of the broken ore can be controlled by adjusting the speed of the rotor. The more advanced ore-ore crusher can not only send the material to the rotor for impact crushing in the crushing chamber, but also send more materials directly to the crushing chamber, and transport the material through the rotor for impact crushing.
The main advantage of the vertical shaft impact crusher is that it can produce high quality products with various particle sizes and high productivity. The geometry of the ore-metal vertical shaft impact crusher enhances the natural crushing effect by minimizing the number of times the given nugget collides with other materials. The product is not only perfect but also beautiful in shape.
Vertical shaft impact rockbreakers have lower cost. In addition, in areas that are more susceptible to wear, the damaged parts are very small and can be made of hard metal at a lower cost. Therefore, the advanced vertical shaft impact crusher can handle abrasive materials. This is a feature that is superior to other types of impact crushers that are primarily limited to handling non-abrasive materials.
This upper feed, bottom-drive vertical shaft impact crusher is lightweight and compact, making it easy to install in existing or new workflows. The disadvantage of this device is that the feed size is limited and therefore cannot be used for initial breakage, usually for secondary crushing. The ore-ore crusher is designed to have a lower crushing rate than the ore-metal crusher. In mining, it is mainly used in the crushing stage of the stone, such as in front of the ball mill . In addition, due to the impact of the ore-ore phase, the wear rate is lower than that of the ore-metal vertical shaft impact crusher, especially when crushing abrasive materials. Another disadvantage is that the vertical shaft has a high rotational speed for efficiently projecting the material, so the vertical shaft impact crusher, especially the ore-ore crusher, requires high kinetic energy.
