Product details
This device is used in conjunction with a semi-autogenous mill. It is divided into two types: the built-in spiral self-return type and the external screening belt self-return type. The core function is to separate the difficult-to-grind and stubborn rocks and scrap steel balls from the crushed materials, and to automatically return the coarse-grained materials back to the mill for further grinding.
After the slurry is screened by the grading sieve, the qualified fine materials enter the next process； the large chunks of hard rocks screened out are transported by a screw / belt conveyor and flow back in the opposite direction to the feed end of the mill for repeated grinding. This effectively avoids the accumulation of hard rocks， which would reduce the grinding efficiency， stabilizes the output particle size， increases the processing capacity of the mill， and reduces the power consumption of the grinding process.
The equipment is equipped with wear-resistant liners, anti-blocking mesh bars, and anti-tear conveying structures, which are suitable for various metal mine grinding production lines. Small grinding machines can be selected with an integrated internal type, occupying a small area; large-scale beneficiation equipment comes with an external self-return system, making maintenance convenient and compatible with cone crushers to achieve pre-crushing of hard rocks, suitable for large-capacity continuous production. The entire structure operates stably, achieving a closed-loop automated cycle for grinding, reducing manual transportation and lowering production losses.

We will uphold the spirit of precision engineering, leveraging its profound technical expertise and end-to-end service capabilities as core drivers.
Working principle: Integrating mechanical, hydraulic, electrical, automation and other technologies, the horizontal shaft is driven by an electric motor to rotate, and the eccentric sleeve is driven by gears to rotate, thereby driving the dynamic cone to make circular oscillations, achieving continuous extrusion and crushing of materials. The crushing chamber is optimized in design, and the crushing effect is not affected by liner wear.

Smelting equipment (blast furnace, converter, electric furnace supporting equipment)
Core positioning: The core equipment for coarse crushing of large materials is mainly used at the front end of the crushing production line to crush large raw materials (with a maximum feed particle size of 1200mm) to ≤ 80mm, laying the foundation for subsequent crushing processes. It is an essential front-end equipment for cement and mining production lines. Working principle: Adopting the principle of squeezing and crushing, the large pieces of material falling between the fixed jaw plate and the moving jaw plate are squeezed and crushed through the reciprocating biting motion of the two jaw plates, achieving coarse crushing processing. It is divided into two types: single elbow plate and double elbow plate. The single elbow plate model has higher production capacity and is suitable for high-yield demand scenarios. Core advantages: simple structure, convenient operation, long service life of wear-resistant parts, large crushing ratio, stable output, suitable for high hardness materials (such as limestone and iron ore), low maintenance cost, suitable for various types of production lines from small to large. Adaptation scenarios: coarse crushing of raw materials in cement production lines, coarse crushing in mining, raw material crushing in sand and gravel yards, coarse crushing in construction waste recycling, etc. Corresponding images (high-definition without watermark, available for direct image search): actual photos of the entire jaw crusher, close-up shots of the jaw crusher feed inlet, jaw crusher mining site, and details of the jaw crusher transmission device.
