High efficiency continuous crushing and processing capacity

In modern mining and aggregate production lines, the crushing efficiency and processing capacity of the equipment are the key indicators of its performance. This equipment is designed based on the principle of gyratory continuous crushing, in which the crushing cone carries out a series of complex and orderly compound movements driven by the eccentric sleeve. This mode of movement creates a continuous extrusion, shearing and grinding effect on the material, thus realising a highly efficient crushing effect. Compared with the traditional jaw crusher, which operates in an intermittent mode, the processing efficiency of this equipment has been significantly improved by more than 30%.

Low energy consumption and operational stability

While pursuing high efficiency, we also pay great attention to the energy consumption and operational stability of the equipment. Through the synergistic design of the hydraulic system and the mechanical structure, the unit energy consumption of this equipment is significantly reduced compared with the traditional models, with a range of 15%-20%. The use of hydraulic drive technology not only realises the infinite adjustment of the discharge opening, which gives the equipment greater flexibility, but also has the overload protection function. When encountering the entry of non-crushed materials, the system will automatically adjust the position of the crushing cone and enlarge the discharge opening, thus effectively avoiding the damage of the equipment. The main shaft of the equipment is supported by heavy-duty bearings, combined with a precision gear transmission system, which significantly reduces the operating vibration of the equipment and effectively extends the life of key components. This not only improves the stability of the equipment, but also reduces the maintenance cost in the later stage.

Intelligent control and maintenance convenience

With the continuous development of science and technology, intelligence has become an indispensable part of modern equipment. CG850i is equipped with an integrated PLC control system, which can monitor the crushing force, bearing temperature, lubrication status and other key parameters in real time. Through the remote terminal, users can grasp the operating status of the equipment at any time, and carry out fault warning and optimisation of process parameters. This not only improves the operating efficiency of the equipment, but also greatly reduces the risk of failure caused by human factors. In terms of maintenance, this equipment also shows a high degree of convenience. The lubrication system with multi-point automatic oiling ensures that the bearings and gears operate with low wear, thus extending maintenance intervals to 1.5 times that of conventional equipment. At the same time, the modular design makes the replacement of liners easier and quicker, reducing the replacement time by 40% and keeping the maintenance window to less than 4 hours, which greatly improves the utilisation of the equipment.

Uniform product size and environmental compatibility

For crushing equipment, the uniformity of product size is one of the most important indicators of its performance. Through the optimised design of the crushing chamber curve, this equipment makes the material go through the process of graded crushing in multiple crushing zones. This not only improves the crushing efficiency, but also reduces the content of needles and flakes in the finished product to less than 10%, and the proportion of cubic aggregate reaches more than 85%, which fully meets the standard of high-end concrete aggregate. In terms of environmental protection, this equipment has also made positive contributions. Its closed structure with pulse dust removal interface reduces the dust emission concentration to below 20mg/m³, which fully meets the requirements of green mine construction. Users can directly connect the equipment to the plant's environmental protection system to achieve zero dust emission. This not only protects the environment, but also improves the social image of the enterprise.

Sell CG850i stationary gyratory crusher high efficiency coarse crushing Working Principle

It adopts high-precision conical crushing chamber, which forms a progressive crushing area between the moving cone and the fixed cone. The cone is driven by the eccentric bushing to rotate and oscillate, and the material is roughly crushed by squeezing, splitting and bending. The crushing chamber has built-in wear-resistant liners, the self-tightening rolling wall design prevents the liners from loosening and prolongs the service life, and the one-piece spherical upper arm bearing replaces the traditional liner, which improves the wear-resistance by 5 times and ensures the constant eccentricity. Driven by an electric motor, the power is transmitted to the eccentric sleeve through the reducer and transmission shaft, driving the dynamic cone to rotate with a specific trajectory. The rotating speed of the cone is matched with the eccentric distance to achieve continuous crushing action. The material enters into the crushing chamber from the top inlet, and when the moving cone is close to the fixed cone periodically, it generates high intensity extrusion and crushes the material; when the moving cone is far away from the fixed cone, the crushed material falls down and discharges from the bottom by gravity. Through the hydraulic system to adjust the height of the fixed cone or the position of the cone, to change the exit gap of the crushing chamber, to control the range of finished product size. Through the deep integration of mechanical design and intelligent control, this equipment solves the pain points of traditional gyratory crusher in terms of efficiency, stability and maintenance cost, and is suitable for large-scale ore coarse crushing scenarios.
