Cone Crusher: Laminated Crushing Type
Cone crusher is a secondary crushing machine only suitable for medium or fine crushing operations. It has strong crushing capacity and high material utilization rate. It has a good effect on crushing various ores with hard and medium hardness and above. It is divided into five types. : Spring cone, composite cone, full hydraulic, multi-cylinder hydraulic and single-cylinder hydraulic, can be used with jaw crusher to form a crushing production line for producing sand and gravel. Its feed particle size can reach 500㎜, and the output is around 12-2000t/h.
Working principle: It adopts laminated crushing. The rotation of the motor passes through the pulley or coupling, the cone crusher transmission shaft and the cone part of the cone crusher, and is forced by the eccentric sleeve to make a swing motion around a fixed point; thus the cone crusher is crushed. The wall sometimes approaches and sometimes leaves the surface of the mortar wall fixed on the adjusting sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing cavity to achieve the crushing of the ore.
Advantages: Suitable for crushing flake materials with uniform particle size; the cone crusher uses hydraulic devices and high-manganese steel wearing parts, which has the advantages of strong pressure resistance, large crushing force, and easy maintenance; the unique hydraulic device can clean the cavity and The function of the protection equipment is to realize automatic discharge and adjust the size of the discharge opening. When foreign matter enters, the cavity clearing function can be started to discharge the foreign matter, resulting in smooth production, safety and convenience. The equipment has a high degree of automation, high production efficiency, and unit power. It consumes less, works more smoothly and consumes less energy.
Disadvantages: complex structure, high cost, difficult maintenance, and high body, which increases the construction costs of factories and basic structures; it is not suitable for crushing wet and sticky ores, nor is it suitable for processing soft ores, and is prone to excessive stone powder. , and the overall cost of the cone crusher is relatively high.
Operation suggestions: The uniformity of discharge particle size in medium and fine crushing operations is generally higher than that in coarse crushing operations. Therefore, a parallel zone must be set up at the lower part of the crushing cavity. At the same time, the rotation speed of the crushing cone must be accelerated so that the material can The parallel zone is squeezed more than once; the crushing of medium and fine crushing operations is larger than that of coarse crushing operations, so the loose volume after crushing will increase greatly. In order to prevent the crushing cavity from being blocked due to this, it is necessary to increase the discharge capacity without increasing the discharge volume. On the premise of ensuring the required discharge particle size, the total discharge section must be increased by increasing the diameter of the lower part of the crushing cone; the discharge opening of the cone crusher is small, and non-crushed materials mixed into the feed It is more likely to cause accidents, and because the medium and fine crushing operations have strict requirements on the discharge particle size, the discharge port must be adjusted in time after the liner is worn, so the safety and adjustment device of the cone crusher is more necessary than the coarse crushing operation.
