The four key factors of the finished product particle size of a single-cylinder hydraulic cone crusher: flexible stroke control to achieve 18-32mm multi-stage adaptation, uniform circumferential feeding technology to increase the processing capacity by 20%, improved crushing chamber to optimize particle size and production capacity simultaneously, and closed production line secondary crushing to increase the fine material yield by 35%. Through the eccentric copper sleeve keyway combination, precise adjustment of the distribution plate and the design of the return system, the performance potential of the equipment is fully released.

Product particle size is the main process indicator for measuring the quality of sand and gravel aggregate products. Shanghai crusher manufacturers share 4 factors that affect the particle size of single-cylinder hydraulic cone crushers.

1. The impact of stroke on product particle size

The stroke refers to the distance between the loose side and the tight side discharge port of the cone crusher, and its size has an impact on the product particle size. In the cone crusher, the stroke depends on the eccentric angle. The single-cylinder hydraulic cone crusher has significant advantages. It can flexibly adjust the eccentric angle according to actual use needs to meet the requirements of stroke under different working conditions.

The stroke of the cone crusher is adjusted through a special design. By using an eccentric copper sleeve with multiple keyways and an eccentric sleeve combination, and rotating the eccentric copper sleeve to correspond to different keyways, different eccentric angles can be formed. In this way, multiple strokes such as 18mm, 25mm, and 32mm can be obtained, which is convenient for matching the appropriate stroke to optimize the product particle size according to the properties of the ore.

2. The influence of feeding method on product particle size

In the operation of the cone crusher, uniform circumferential feeding is of great significance. It can not only improve the product particle size and increase the processing capacity, but also make the crushing wall and the mortar wall evenly stressed, and extend the service life of the equipment. In actual operation, this effect can be achieved with the help of a distributor, and the key is to properly adjust the height between the feed hopper and the distributor.

When the height is too high, only a small part of the stone passes through the distributor, so uniform circumferential feeding cannot be achieved. When the height is too low, the stone is easy to block, reducing the processing capacity. In addition, when the single-cylinder hydraulic cone crusher is full of feed, it can not only give full play to the capacity of the crusher, but also improve the product particle size.

3. The influence of the crushing chamber type on the product particle size

According to the on-site use, the improved crushing chamber in the figure below not only greatly improves the product particle size, but also increases the crusher throughput.

4. The influence of the production line layout on the product particle size

The production line has two layout modes: open and closed. The open production line is from coarse crushing to medium crushing to fine crushing, without return material; while the closed production line is from coarse crushing to medium crushing to fine crushing, some products are screened and returned for secondary crushing. The unqualified return material is crushed multiple times, and the finished product shape is better, especially the fine material product is more prominent.
