Abstract

The invention provides a double-roller RAP crushing machine. The double-roller RAP crushing machine comprises a machine frame, a crushing machine body, a collection hopper and a belt conveyor. The crushing machine body comprises a crushing machine case, a first crushing device, a second crushing device and a tensioning buffer device, wherein the first crushing device and the second crushing device are provided with a first crushing roller and a second crushing roller correspondingly, the first crushing roller and the second crushing roller each comprise a rotary shaft and a tooth plate, each tooth plate is in an arc shape, a plurality of arc-shaped protruding parts are arranged on the surface of each tooth plate, and a concave cavity is formed between every two adjacent arc-shaped protruding parts. A plurality of scraping tooth devices are arranged on the crushing machine case, and the scraping tooth devices and the tooth plates are arranged in a staggered mode. The tensioning buffer device is pivoted to the second crushing device. According to the crushing machine, through the crushing roller tooth plates which are arranged in a staggered mode and the floating crushing roller structure, RAP with large specifications can be rubbed, squeezed and torn alternately, and the asphalt bonding effect in the RAP is destroyed; and meanwhile, aggregate can enter the concave cavities so as to be prevented from being crushed and broken, and thus the original grade of the RAP is prevented from being destroyed.

Description

technical field [0001] The invention relates to the technical field of asphalt production equipment, and more specifically refers to a double-roller asphalt pavement milling material crusher and a crushing method thereof. Background technique [0002] Asphalt pavement regeneration technology is to dig, recycle, crush and screen the old asphalt pavement that needs to be renovated or discarded, and then mix it with new aggregate and new asphalt materials to form recycled asphalt with certain road performance. Mixture, a complete set of technology for paving the surface layer or base layer of the pavement. Among them, the factory mixing hot regeneration method is to transport the old asphalt pavement back to the asphalt concrete mixing station after milling, digging and excavation, and then crush it in a centralized way. The proportion of materials such as additives, new asphalt materials, new aggregates, etc., and then mixed in asphalt concrete mixing equipment to form a new ...
