G Series High-pressure Roller Mill

In response to the increasing demand for scale, intensification, energy conservation, environmental protection, and high-quality mechanism sand in the sand and gravel market, Shijiazhuang Haihui Machinery Co., Ltd. has further optimized the structure and function of the roller sand making machine based on more than 20 years of practical sand making applications, and launched a new generation of high-efficiency and low-cost sand making equipment - high-pressure roller sand making machine. The G series roller sand making machine adopts cutting-edge sand making design concepts. Compared with similar products, it has higher sand making efficiency, easier operation, and more importantly, can comprehensively and efficiently solve customer concerns about output, product particle size, production maintenance costs, and applicability. The roller sand making machine improves its sand making capacity by adjusting the pressure between the rollers. The finished sand accounts for more than 90% of the raw materials, which is beyond the reach of other crushers.

Working principle:

1. This series of roller machines mainly consists of a motor, internal drive assembly, grinding roller, main frame, sliding frame assembly, spring, reinforced crossbeam fixed shaft seat, hydraulic station, shock absorber mechanism and other components. The structure is compact and precise, and the movement and rotation are smooth. The fixed grinding roller is fixed on the main frame with bolts, and the other set of grinding rollers can slide as a whole on the main frame with the change of spring pressure, automatically adjusting the gap between the two sets of grinding rollers, that is, the fineness of the finished product. If metal debris falls between the two grinding rollers, the sliding grinding roller compresses the spring due to impact, which can cause the sliding grinding roller to retreat, thus achieving the purpose of not damaging the equipment.

2. Automatic adjustment of discharge fineness, based on the hardness and feeding conditions of the material, adjusts the pressure of the spring to cause the sliding frame assembly to move slightly, thereby achieving the gap between the sliding frame assembly (with a set of grinding roller assemblies installed on it) and the fixed assembly. At the same time, the adjustment screw should be loosened to facilitate automatic sliding without obstruction (the gap is required to be within 10MM). When the material enters the gap between the two grinding rollers for sanding; Due to the reactive force, the sliding grinding roller can be instantly compressed and ejected slightly, while rotating towards the opposite direction to crush the material to achieve the required fineness. When the two grinding rollers wear out and the discharge fineness increases, the adjustment screw should be loosened again, and the hydraulic supply station oil should compress the spring again to achieve automatic adjustment of fineness.

3. The driving mechanism is transmitted from the motor to the high-speed shaft of the hard gear through a coupling, driving the internal drive transmission assembly, and then transmitted to the grinding roller through the coupling to rotate in the opposite direction, thereby crushing the material and discharging the finished product from the discharge port.
