The mobile station used in the construction waste crushing plant is more convenient, mainly because it is easy to move, the conversion site is free, and the cost of installation time and construction waste transportation is saved. What is the difference between the two and what are the advantages when it comes to crushing?
1. Multi-cylinder hydraulic cone crusher
Compared with single-cylinder hydraulic cone crusher, multi-cylinder hydraulic cone swing frequency is high, eccentricity is large, and the taper is relatively low. At the same time, the design of the surrounding multi-cylinder hydraulic lock is adopted. The spindle is in the form of a cantilever beam support and a spherical tile. The support structure, discharge port adjustment, iron automatic protection, cavity and other actions are all adjusted by the hydraulic motor, which makes it easier to lock the discharge port when the harder material is crushed, and can provide a more powerful crushing capacity. Therefore, it is more suitable for crushing harder materials and has a strong processing capacity. 70-80% of the emission components are materials with discharge port size, and the needle content of the emission can be controlled to less than 10%.
But, on the other hand, due to the smaller ball radius of multi-cylinder cone crushers, the radius of slew is smaller and it is relatively prone to potential problems such as cone movement, tipping and flying. If the contact between the spindle and the bushing is poor, if the impact force is too large, it will seriously affect the normal operation of the equipment, but its processing capacity is high, and the material smaller than the discharge port can even account for 70% to 80% of the processing capacity.
2. Single-cylinder hydraulic cone crusher
First of all, we have to look at the single-cylinder hydraulic cone crusher. This kind of main frame adopts the support design of the main shaft girder. The single-cylinder hydraulic support at the bottom and the star-shaped frame at the top have a steep taper and a high sway frequency. The eccentricity is small.
The single-cylinder hydraulic cone crusher adopts the design of a single hydraulic cylinder at the bottom, which completes the action of adjusting the size of the discharge outlet, the protection of iron and the cleaning cavity, and integrates the functions of the independent hydraulic cylinder at the bottom, thus greatly reducing various auxiliary adjustment devices. The utility model discloses a compact structure, adjustment is convenient and quick, the structure is relatively simple, the equipment cost is low, but the performance is relatively stable, and is particularly suitable for adopting automatic control system. Due to the large spherical radius supported by the moving cone and the small spindle eccentricity, the overall shape of the crushing chamber is longer, and the load of the material is more uniform throughout the lamination process of the chamber, which improves the uniform distribution of the crushing chamber. Crushing force, and the final discharge particle size is uniform. The needle content is low, and the crushing force and power fluctuate smallly.
However, the so-called Cheng Xiaoxiao defeated Xiao He, and the single-cylinder hydraulic cone crusher has a relatively simple structure, so its crushing force is not high compared to multi-cylinder hydraulics. Crush the high hardness material, at the same time, because the lifting cylinder is adjusted by the bottom hydraulic cylinder to adjust the size of the discharge port, in the case of uneven feed size, it is easy to increase the wear of the rolling wall, and at the same time, because the main mechanism of action - the hydraulic cylinder is located at the bottom of the equipment, the maintenance work will bring certain difficulties.
Third, the comparative analysis of multi-cylinder hydraulic cone crusher and single-cylinder hydraulic cone crusher
All in all, since the adjustment effect of discharge adjustment is achieved by adjusting the fixed cone by multiple hydraulic cylinders, the crushing efficiency, crushing force and crushing rate of the multi-cylinder hydraulic cone crusher are relatively high in terms of crushing capacity. , so the adjustment range is relatively wide, and there is more flexibility in product grading adjustment. Therefore, both in terms of performance and final emissions, a multi-cylinder hydraulic cone crusher is superior to a single-cylinder cone crusher. The multi-cylinder hydraulic cone crusher can effectively simplify the crushing process, reduce the number of crushing stages, reduce the system investment, and it is the preferred equipment for crushing hard rock.
Of course, the single-cylinder hydraulic cone crusher has a simple structure and a relatively low investment, which is a good choice for crushing materials with high general hardness and wear-resistant.
