The cone type crusher produced by Henan Hongxing Mining Machinery Co., Ltd is suitable for crushing various mid-hard and above mid-hard ores and rocks. This machine has novel and unique structure such as simple and reasonable, reliable operation, high output, and low operation costs. Based on importing and absorbing foreign technology, this machine is a modern high-performance crusher. It is manufactured and designed through absorbing the latest world advanced technology and gets to be world advanced level. A set of external lubrication system was adopted including pump, tank and pipeline. When the oil temperature is too high or the flow rate is too slow, the crusher will be shut down automatically. Hydraulic system is equipped to adjust the discharge opening size promptly. The machine body is cast steel structure. Reinforcing rib is set at the high strain point of the heavy-load parts. The drive shaft’s two ends are assembled with tapered roller bearings, and the power-driven system is supported by the heavy-load bevel gear. Spring-loaded iron release protection is provided. The spring safety system is overload protective device, allowing iron pieces get through the crushing chamber without damaging machines. This equipment is mainly applied to the tertiary or the fourth stage crushing of metal mine concentrating mill. The cone crusher produced by our company is also suitable for the following fields like building materials, non-metallic mines or other civil engineering industries, especially in the areas where natural sand is in short supply.

According to demand of customers, it is developed based on laminated crushing principle and conceptual design of “more crushing and less grinding”; thus this type of hammer crusher is integrated with high wobble frequency, optimal cavity shape and reasonable stroke. CS series of highly efficient cone crusher has more reasonable and perfect structure and more advanced technology.

The function of the spring is to protect the crushing machine on the condition of there is any non-crushable materials. It won’t be compressed during correct function unless there is any iron ore in the crushing chamber and the crusher is overload so the supporting sleeve is raised up.

The top moving up and down during normal operation should be analysis carefully for this situation is abnormal. So measures should be taken to solve it. If compress the spring incorrectly, the components of the jaw crusher may be damaged without any help to the normal working for the compressed spring will lead to the increasing of the crushing force.

Reasons for the moving up and down of the top of the crushing machine:

A. feeding uneven or superabundance

B. overmuch small blocks, powdery ores and high humidity

C. discharging opening is too small, so that the rotating part with air exposure should covered by self-prepared shields.
