Description

Use crushing roller in pitch breaker

Technical Field

The utility model belongs to the technical field of solid useless processing, concretely relates to use crushing roller in pitch breaker.

Background

The asphalt pavement recycling technology is a whole set of process that old asphalt pavement needing to be renovated or abandoned is re-mixed with a regenerant, new asphalt, new aggregate and the like according to a certain proportion into a mixture after being dug, recovered, heated, crushed and screened by special pavement regeneration equipment, so as to meet certain pavement performance and be re-paved on the pavement. The pavement regeneration can not only satisfy the pavement performance requirement again, save a large amount of material resources and funds, reduce the construction cost, but also avoid the pollution of waste materials to the environment, realize industrial recycling economy and promote the ecological environment protection, is a specific practice for implementing strategic measures of 'conservation-minded society' and has very remarkable social and economic benefits.

Asphalt is considered to be a colloid dispersion system by the theory of asphalt colloid structure, and the dispersed phase of the asphalt is a micelle formed by adsorbing part of colloid by taking asphaltene as a core and is dispersed in a dispersion medium consisting of aromatic hydrocarbon and saturated hydrocarbon. Studies have shown that bitumen has better properties only if the relative proportions of the components in the bitumen satisfy a certain relationship. The essence of the deterioration of the quality of asphalt pavement is the aging of asphalt binder, i.e. the change of the components of asphalt cement, the reduction of aromatic components and the increase of colloid and asphaltene. The changes in the physical and mechanical properties of the asphalt caused by the "migration" of the chemical components of the asphalt can result in reduced penetration, reduced ductility, increased softening and brittle points, and increased hardening, embrittlement and reduced ductility of the asphalt. According to the theory of component regulation, the lost components are added into the aged asphalt, so that the proportion of the components is reconciled, and the performance of the asphalt can be recovered. Because the fresh soft asphalt contains more soft asphalt components, the performance of the old asphalt reaches a certain level through blending, thereby achieving the aim of asphalt regeneration.

The pretreatment stage of the regeneration process needs to crush the recycled asphalt blocks, the existing crushing equipment is a double-roller crusher which has the advantages of simple structure and less excessive crushing phenomenon, and the tooth form, the size and the arrangement on the roller surface can be changed along with the material property and can crush medium-hard and soft solids. However, the structure of the crushing roller used in the existing crusher cannot be directly applied to the asphalt treatment with certain viscosity, and the existing crushing roller is of a fixed structure and cannot be adjusted according to the feeding characteristic.
