Spring cone crusher (PY series) has excellent combination of crushing cavity type and crushing frequency, it leads to a great increase of crushing capacity. At the same time, it absorbs the principle of laminated crushing, which reduces the needle-shaped materials to a certain extent. The spring-loaded safety system is an overload protection device that provides “spring-loaded” over-iron release protection against non-breakable objects like iron, with a failure-free operation rate of over 95% under normal use.

3. Spring cone crusher structures
Spring cone crusher is mainly composed of main frame, transmission device, eccentric shaft, bowl bearing, crushing cone, adjusting device, adjusting sleeve, spring, discharge opening adjusting device, hydraulic station for lubrication, etc.
4. Working principle
The spring cone crusher uses the working surface between the movable cone and the fixed cone to crush the rocks. The movable cone is supported on a spherical bearing and fixed on a suspended vertical shaft, it is placed in an eccentric sleeve, the eccentric in turn is placed on a thrust bearing.
The moving cone is driven by the eccentric sleeve together with the vertical shaft, and the eccentric sleeve is driven by the horizontal shaft via the pulley and the bevel gear. The belt pulley is driven by the motor through triangular belts.
The lower part of the vertical shaft is installed in the eccentric sleeve, and when the eccentric sleeve rotates, a cone surface is formed by the shaft. Therefore, the rock is crushed when the moving cone is close to the fixed cone.
The housing is made up of two parts, which are connected by bolts. Strong springs are attached to the bolts, which is used to prevent damage to the crusher when metal or other hard objects fall into the crushing chamber. After the rocks are crushed, they will be discharged from the bottom part.
1. Higher capacity and better quality.
2. Due to the safety device, the downtime is greatly reduced.
3. The body with cast steel structure, with reinforcement bars in the heavy load part.
4. It contains adjusting device, which can quickly adjust the discharge size.
5. It provides spring type protection device.
6. With complete lubrication system, it will automatically shut down when there is too high temperature or too slow flow rate.
7. The internal structure has good sealing performance, which can effectively protect the equipment from dust and other small particles.
8. Long service life and strong applicability.
Spring cone crusher is developed on the basis of digesting and absorbing various types of cone crushers of various countries with international advanced level in 1980s. It is obviously different from the traditional cone crusher in design, and concentrates the main advantages of all types of cone crushers known so far. It is suitable for fine crushing and ultra-fine crushing of hard rocks, ores, slag, refractory materials, etc.
The Spring cone crusher can be widely used in metallurgical industry, construction industry, road building industry, chemical industry and phosphate industry, suitable for crushing hard and medium hard ores and rocks, such as iron ore, copper ore, limestone, quartz, granite, basalt, pyrochlore, etc. The crushing chamber type is determined by the ore use, generally speaking, the standard type is applied to medium crushing. The medium type is applied to fine crushing. The short head type is applied to ultra-fine crushing. As casting steel technique is adopted, the machine has good rigidity and large high strength.
7. Cautions for spring cone crusher
1. Choose suitable crushing chamber and appropriate feed size.
2. Make sure the material is evenly distributed after entering the crushing chamber.
3. Keeping the discharge opening clear.
4. Reduce sticky materials, because it will reduce the overall productivity.
5. The crushing capacity should meet the belt conveyor’s capacity.
6. Motor power should meet the standards of spring cone crusher requirements
7. Start the lubrication station 5 minutes earlier than the spring cone crusher
8. Keep lubrication station running 5 minutes after stop the main motor
9. Always operate according to Deya Machinery’s spring cone crusher manual.
