The cone crusher is an important processing equipment in the aggregate production line and plays an important role in the medium and fine crushing. It can process river pebble, granite, basalt, iron ore, limestone, quartzite, diabase, iron ore, gold ore, copper ore and other non-metallic ores and metal ores, and is widely used in mine crushing and construction crushing.

Discussion on spring cone crusher and hydraulic cone crusher

Cone crusher products appeared at the end of the 19th century. Therefore, in the long process of technological development, this cone crusher has undergone long-term and continuous innovation, and has become a fairly mature mechanical equipment. It should be noted that the cone crusher must be equipped with a safety device. During the whole operation process, because the crushing force is pulsating, there will be unbreakable objects such as iron blocks in the crushing. The safety device can eliminate this and protect the machine.

According to different safety devices, cone crushers can be divided into spring type and hydraulic type. The Symmons cone crusher is actually a spring cone crusher that uses a spring to play a safety and locking role. Because the spring type is a single-particle crushing cavity type, the material is broken between the liners. The product has a large proportion of elongated particles, short liner life, and the spring cone crusher has a small iron stroke, which makes it difficult to clean the cavity and push the cylinder. It is not convenient to adjust the discharge opening. Therefore, the market position of spring cone crushers is gradually decreasing, and at the same time, the popular trend of hydraulic cone crushers is becoming more and more obvious. The hydraulic cylinder of the equipment replaces the spring to provide overload protection, and at the same time the hydraulic cone crusher has the function of clearing the cavity, and the overload protection stroke is enlarged, the response is sensitive, and the efficiency is improved. What is worth mentioning is the laminated crushing principle of hydraulic cone crusher. In this case, the crushing occurs between the material and the material. The defective material and the elongated material with weak strength are crushed first, and the product is cubic. The life of the liner is basically not affected.

According to the number of hydraulic cylinders, hydraulic cone crushers can be divided into multi-cylinder hydraulic cone crushers and single-cylinder hydraulic cone crushers. They are both high-performance crushers, and they all realize the lamination crushing process. They have their own advantages due to different structures. The multi-cylinder hydraulic cone breaker has a slower taper and a lower passing capacity, and a large stroke is required to compensate for the low passing capacity. The more impact of material, the better the output of fine crushing. At the same time, the equipment has compact structure, high crushing pressure, good particle shape of the finely crushed product, good lamination crushing effect, and high energy efficiency ratio of fine crushing.

The single-cylinder hydraulic cone breaker has a steeper taper and a higher passing capacity. The number of times the material is impacted is small, and it is necessary to increase the swing frequency of the moving cone and increase the height of the large cavity to compensate. In addition, its moving cone has good stress conditions, long life of spare parts (bearing copper parts), good crushing effect, and large passing capacity. The product realizes intelligent control, dynamically adjusts the discharge port, motor power, and crusher pressure with load, automatically detects and adjusts the discharge port, and can display various operating parameters in real time.

When selecting the type and model of cone crusher, it is necessary to comprehensively consider factors such as the type of raw ore, water content, and particle size of the feed material, and configure it according to the actual situation. Both the multi-cylinder hydraulic cone crusher and the single-cylinder hydraulic cone crusher produced by CFTC have a variety of ultra-coarse, coarse, medium, fine, and ultra-fine cavity types, which can meet the continuous production range of 100 tons to 800 tons. Our hydraulic cone crusher is a crushing product that combines crushing stroke, crushing speed and crushing cavity type, and its output is about 35%-60% higher than that of spring cone crusher. The automatic control system of the single cylinder hydraulic cone crusher provides multiple operation modes such as manual control, constant discharge port control, and constant power control. It is an intelligent operation product.

Whether it is a multi-cylinder hydraulic cone crusher or a single-cylinder hydraulic cone crusher, they have their own advantages and applications. Of course, they can also be combined to form a pure cone crusher production line. For details, please contact the technical staff of CFTC, we will provide you with a mature and reasonable solution.
