is one of the most popular medium and fine crushing equipment, suitable for crushing various medium hard and hard materials. The output of the cone crusher is affected by many factors. If the values of these factors are selected appropriately, the output of the equipment will increase. This article mainly shares 7 factors that affect the output of cone crushers.
1. Rotation speed of moving cone
The rotating speed of the moving cone is an important factor affecting the output of the crusher. If the rotating speed is too slow, the material will slide through the crushing cavity along the contour of the moving cone liner, and it will take a long time to pass through the crushing cavity, so the output is definitely low, and the particle size of the product will also deteriorate; but if the rotating speed is too fast , The material will hardly be discharged downwards, even if it is broken, there will be a stagnation time after the material is broken, and blockage will definitely occur. At this time, the output can be imagined, so there is an ideal rotation speed.
2. The length of the parallel zone
The starting point of the parallel zone is the plugging point of the crushing cavity, and the shorter the length of the parallel zone, the lower the position of the blocking point. This is equivalent to increasing the actual moving cone diameter of the crushing cavity, resulting in higher output, but then the crushing The quality of the product will deteriorate; the longer the length of the parallel zone, the higher the position of the clogging point. At this time, the output decreases, but the product quality becomes better.
The parallel belt is longer, and both the feeding and discharging outlets are relatively small, and a finer product particle size can be obtained. Generally, the short head type with a longer parallel belt is used as the fine crush and placed after the middle crush. The standard type, due to the short parallel belt, makes the crushed product thicker and has a higher output. It is generally used for intermediate crushing after the coarse crushing, that is, after the jaw or gyratory crusher.
3. The bottom angle of the moving cone
The bottom angle of the moving cone determines the inclination angle of the moving cone. The larger the bottom angle of the moving cone, the easier it is for the material to make a free fall movement. However, in this case, the number of times the material is crushed and crushed when passing through the crushing cavity will be less, although the output When the bottom angle of the moving cone becomes smaller, the surface of the moving cone will become smoother, and the material will slide along the crushing motor cone liner, and the output will be lower, but the quality of the crushed product will change at this time. OK; in addition, the size of the bottom angle of the moving cone will also determine the height of the fixed point of the crusher. When the bottom angle of the moving cone becomes larger, the position of the fixed point will become higher, and the material will be more likely to fall freely in the crushing cavity. At this time, the lamination effect is obvious, and the output is increased; when the bottom angle of the moving cone becomes smaller, the position of the fixed point will decrease, and the lamination effect is not good at this time, and the output is reduced.
4. Angle of precession
The precession angle will directly determine the eccentricity of the crusher and the swing stroke of the discharge port. When the precession angle increases, the eccentricity of the crusher and the swing stroke of the discharge port will increase, and the material will fall freely, so the output will increase, but the number of times the material is crushed in the crushing cavity will be reduced, resulting in The quality of the product declines; when the precession angle becomes smaller, the eccentricity of the crusher and the swing stroke of the discharge port will become smaller, which will cause the material to pass through the crushing cavity for a longer time, and the output will decrease, but the material will be more easily broken. The cavity is broken to improve the quality of the product. Therefore, on the basis of ensuring the quality of the product, reducing the precession angle will increase the output of the product.
5. The size of the closed side discharge opening
The size of the closed-side discharge port determines the output of the cone crusher. When the size of the closed-side discharge port becomes larger, the output of the cone crusher becomes larger, but the quality of the crushed product deteriorates. The content increases; when the size of the closed-side discharge opening becomes smaller, the output of the cone crusher becomes smaller, but the quality of the crushed product becomes better.
6. Material filling rate
The filling rate of the material has a very important relationship with the output of the crusher. When the filling rate of the material is too small and the material cannot fill each crushing layer, the output will definitely decrease; when the filling rate is too large, the material will fill the crushing cavity. It is full, but the material is compressed, it is not easy to be laminated and crushed, and the material is not easy to pass through the crushing cavity, resulting in low output and poor quality of the crusher. Therefore, in the feeding process, there is an ideal material filling rate.
7. Operating factors of the crusher
The impact of the crusher's operating factors on the output is subjective and can be completely avoided, but if these subjective factors are not paid attention to, it will have a great impact on the output of the crusher. The operating factors that affect the output of the crusher include: whether the feed is sufficient and the particle size of the feed is uniform. When the crusher is working, if the feed is insufficient, the crusher will be in a working state for nothing, resulting in a serious decline in output; if the feed size distribution is uneven, or even the size difference is large, the crushing force will be unreasonably distributed, resulting in lining Severe plate wear will greatly affect the output of crushed products.
