Abstract
The invention relates to a double-roller preliminary crushing and compression feeding device for a crusher and a feeding method. Double-roller preliminary crushing and compression feeding are adopted, and triangular toothed blocks and horizontal strips are arrayed on a wheel face of a double-roller body. A feeding port is provided with double rollers, the problems of continuous rolling and continuous conveying of materials such as long and high waste steel and the like and preliminary crushing of shell feeding are effectively solved, and various materials such as the waste steel and the like are effectively conveyed into a main crusher. The double rollers are hydraulically driven to be controlled and are different in linear speed, the fronts of the double rollers are high while the backs of the double rollers are low relative to a feeding channel, and the materials such as the long and high waste steel and the like can be fed. The double rollers are mounted on a double-roller moving frame hydraulically driven, two lower sides of the double-roller moving frame are respectively controlled by a group of hydraulic cylinders, and the space between each roller and the feeding channel can be adjusted. The hydraulic cylinders are narrowed to the shortest in normal operation, the moving frame is positioned at the lowest point, and the height of the moving frame can be properly adjusted when large materials need to pass through the moving frame. The hydraulic cylinders can be elongated in maintenance and can be fixed by a fixing pin when reaching the highest point.
