Abstract

The invention discloses a crushing treatment method for a waste railway sleeper. The crushing treatment method comprises the following steps that S1, the sleeper is clamped for feeding; S2, the sleeper is crushed; S3, crushed materials formed after primary crushing of the sleeper enter a conveyor; S4, the conveyor conveys the materials to a belt conveyor, and on the conveyor, a magnetic separator performs magnetic separation on the materials; S5, the belt conveyor conveys concrete to a concrete conveyor, and the concrete conveyor conveys other materials to a feeding port of an impact crusher; S6, the materials are conveyed to a sorting sieve after being finely crushed through the impact crusher; S7, magnetic separation is performed to separate out materials; and S8, the concrete is vibrated and sorted, the concrete is sorted to corresponding finished product material conveyors according to particle sizes, and aggregate screening is finished. The device solves the problem that the waste sleeper in the field of rail transit is difficult to dispose, and has the beneficial effects of being compact in structure, novel in design, complete in sleeper recovery disposal, safe, environmentally friendly, efficient, energy-saving, intelligent, controllable and integrated.

Description

technical field [0001] The invention belongs to the technical field of railway circular economy equipment manufacturing, and in particular relates to a method for crushing and disposing of railway waste sleepers. Background technique [0002] Railway cement sleepers are mixed with cement, sand, stone, water and admixtures in a certain proportion to form a mixture, which is injected into a combined model equipped with steel wires or steel bars and sleeper accessories, and is formed by vibration molding or loading vibration molding, steam curing, and relaxation. Concrete sleeper products made of steel wire or steel bars, cut sleeper ends, etc. Since the start of construction of the entire line of the Beijing-Kowloon Railway in 1993, the domestic railway demand for sleeper materials has entered a period of rapid growth, and the current annual investment exceeds 10 million. During the investigation of various railway bureaus, it was found that a large number of waste sleepers w...
