As a two-breaking equipment in the production line, the hydraulic cone crusher is suitable for crushing various medium and hard materials after smashing. It has large production capacity, large crushing ratio, good grain shape, low energy consumption and high automation. It is characterized by high reliability, simple operation and maintenance, and low cost of wearing parts. It is one of the most popular medium and fine crushing equipment. Today, we will take everyone to understand the factors affecting the output of the hydraulic cone crusher. I hope that everyone can provide some reference when choosing or using the crusher, grasp these points and improve the output of the hydraulic cone crusher.

1. Manual operation factors

The impact of the crusher's operating factors on production is subjective. If these subjective factors are not noticed, it will have a great impact on the crusher's output. The operational factors affecting the crusher's output include whether the feedstock is sufficient, whether the feedstock has a uniform particle size, and the like. When the crusher is working, if the feeding is insufficient, the crusher will be in working condition, resulting in serious decline in production; if the particle size distribution of the feed is uneven, even if the particle size is very different, the crushing force will be unreasonably distributed, resulting in lining. The wear of the board is severe and will greatly affect the output of the broken product.

2. Material filling amount

The filling amount of the material has a very important relationship with the output of the crusher. When the material filling amount is too small, the material cannot fill every broken layer, then the output will definitely decrease; when the filling amount is too large, the material fills the crushing chamber. Full, but the material is compacted, it is not easy to laminate and crush, the material does not easily pass through the crushing chamber, resulting in low output of the crusher and poor quality. Therefore, in the feeding process, it is necessary to grasp this degree and give the appropriate material filling amount.

3. Moving cone rotation speed

The rotational speed of the moving cone is an important factor affecting the output of the crusher. If the rotation speed is too slow, the material will slide through the crushing cavity along the contour of the moving cone liner, and it takes a long time to pass through the crushing chamber, so the yield is definitely low, and the particle size of the product is also deteriorated; the material will almost never be discharged downwards. Even if it is broken, there will be a stagnation time after the material is broken, and the clogging phenomenon will definitely occur.

4. The length of the laminated broken 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 plugging point, which is equivalent to increasing the actual moving cone diameter of the crushing cavity, resulting in higher yield, but then the broken product The quality will deteriorate; the longer the length of the parallel zone, the higher the position of the plugging point, and the yield will decrease, but the quality of the product will be better. The parallel belt is longer, and the ore and discharge ports are relatively small, and the finer product size can be obtained. Generally, the short head type with a longer parallel strip is placed as a fine crush after being placed in the middle. The standard type is short in parallel, so the crushed product is coarser and the output is higher. Generally, it is used as a medium crush after the coarse crushing, that is, after the smashing or rotary crushing machine. Therefore, the model of the cone crusher should be selected according to the demand of the material.

5. Eccentricity size

The magnitude of the precession angle directly determines the eccentricity of the crusher and the swinging stroke of the discharge port. When the precession angle becomes larger, the eccentricity of the crusher and the swing stroke of the discharge port become larger, and the material is more likely to fall freely, so the yield is increased, but the number of times the material is crushed and broken in the crushing chamber is reduced, resulting in The quality of the product decreases; when the precession angle becomes small, the eccentricity of the crusher and the swinging stroke of the discharge port become smaller, resulting in a longer time for the material to pass through the crushing chamber, and the yield is lowered, but the material is more likely to be 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 yield of the product.

6. Tight side discharge opening size

The size of the tight side discharge port determines the output of the cone crusher. When the size of the tight side discharge port becomes larger, the output of the cone crusher becomes larger, but the quality of the broken product deteriorates, and the content of the needle-shaped material in the product increases. Large; when the size of the tight side discharge port becomes smaller, the output of the cone crusher becomes smaller, but the quality of the broken product becomes better.
