What machines are used for recycled aggregate production?
Recycled stone processing machinery mainly includes feeders, jaw crushers, impact crushers, cone crushers, vertical shaft impact crushers, vibrating screens, mobile crushing stations, as well as supporting impurity removal and conveying equipment. These machines are widely used to turn construction waste, industrial tailings and other solid wastes into qualified recycled stone aggregates.
1. Feeding and Pre-screening Equipment
The F5X series vibrating feeder serves as key feeding equipment. Equipped with bar pre-screening function, it can evenly deliver bulk materials and remove soil and fine impurities in advance to ensure high crushing efficiency. Featuring modular structure, it is easy to install and maintain, perfectly suitable for continuous operation of recycled aggregate production lines.
2. Primary Crushing Equipment
The C6X series jaw crusher is the ideal primary crushing unit. Its deep crushing cavity design avoids material blocking effectively, which can crush large solid waste materials into particle sizes between 150mm and 200mm. Adopting high-strength wear-resistant parts, it features strong hard rock processing capacity and stable output, ideal for primary crushing of construction waste and concrete blocks.
3. Medium and Fine Crushing Equipment
The PFW European-style hydraulic impact crusher comes with enlarged and reinforced rotors. It can handle large-size raw materials with high finished product yield and adjustable discharge size, well suited for medium-hard material secondary and fine crushing.
The HPT multi-cylinder hydraulic cone crusher works on laminated crushing principle. It supports automatic iron removal under overload conditions and intelligent hydraulic gap adjustment. Finished aggregates feature low flaky particle content and uniform grain size, ideal for fine crushing of high-hardness materials.
4. Shaping and Sand Making Equipment
The VSI6X series vertical shaft impact crusher is specially used for recycled stone shaping. High-speed material collision optimizes particle shape for smoother and rounder grains, greatly improving aggregate quality to meet strict standards of high-grade recycled aggregates.
5. Screening Equipment
The S5X series vibrating screen is fitted with modular high-power vibrators, delivering strong vibration force and much higher screening efficiency than traditional screening machines. Its processing capacity ranges from 25 tons to 900 tons per hour, fully meeting graded screening demands in recycled aggregate production.
