Product Overview
This double roller crusher is specially optimized for waste asphalt recycling and crushing working conditions. Waste asphalt materials feature strong viscosity, easy agglomeration and temperature softening characteristics. Conventional crushing equipment tends to cause material bonding, blockage, aggregate over-crushing and excessive fine powder during processing, resulting in disordered recycled aggregate gradation and failing to meet road recycling material standards. Adopting upgraded anti-stick and anti-blocking structure and standardized low-speed gentle extrusion crushing technology, the equipment realizes stable dispersion and crushing of caked waste asphalt. It effectively retains complete aggregate grain shape with controllable powder rate and uniform gradation, perfectly meeting the technical requirements of waste asphalt resource recycling, old road material renovation and recycled aggregate reuse production lines.
Key Features
Professional optimization for viscous waste asphalt recycling crushing: Equipped with specially treated anti-stick roller surface and streamlined non-blocking cavity structure, the machine thoroughly solves asphalt adhesion, material accumulation and blockage problems in recycled material processing. The low-speed mild extrusion and shearing mode disperses agglomerated asphalt mixtures evenly without violent impact or over-grinding. It avoids damage to original stone aggregate structure, maintains reasonable recycled particle gradation, and improves the overall quality of recycled asphalt materials.
Precision adjustable roller gap flexibly controls finished recycled aggregate particle size, supporting diversified granularity requirements for road base materials, recycled pavement materials and construction recycled aggregates. The whole machine adopts heavy-duty reinforced structure with stable operation, low vibration and low energy consumption. It adapts to long-term continuous cyclic crushing of complex waste asphalt materials with low failure rate. The simplified structural design enables convenient daily maintenance and inspection, effectively reducing comprehensive operating costs of asphalt solid waste recycling projects.
Working Principle
Driven by a stable power transmission system, the two rollers rotate synchronously in opposite directions. Bulk and agglomerated waste asphalt materials are evenly and quantitatively fed into the crushing cavity. Through continuous and uniform mild extrusion and micro-shearing force, integrated asphalt blocks are fully dispersed and crushed into standard recycled aggregate particles. The scientific low-speed crushing mode prevents over-crushing of asphalt and stone materials, stabilizes finished particle gradation, and provides high-quality qualified granular materials for subsequent asphalt recycling and reuse procedures.
Applicable Materials
Suitable for waste asphalt pavement materials, old asphalt concrete blocks, asphalt recycled mixtures and other road asphalt solid wastes. It is specially used for crushing, dispersion and particle pretreatment of waste asphalt raw materials in road resource recycling projects.
Application Scope
Widely applied in road asphalt recycling plants, old road renovation material processing lines, construction solid waste recycling projects, recycled aggregate production workshops and road base material processing systems. It serves as core dedicated crushing equipment for waste asphalt resource recycling working conditions.
Product Advantages
This waste asphalt recycling dedicated double roller crusher solves the industry pain points of traditional equipment such as easy sticking and blockage, serious aggregate over-crushing and unstable recycled material quality in asphalt recycling processing. It features outstanding anti-sticking performance, stable crushing quality, uniform finished gradation and low comprehensive failure rate. It effectively improves waste asphalt resource utilization rate, reduces solid waste accumulation and project material costs. It is a reliable, energy-saving and cost-effective crushing solution for all kinds of road asphalt green recycling projects.
