Foreword: The processing of renovation waste requires a series of specialized equipment, including feeding devices, crushing equipment, screening equipment, sorting equipment, conveying equipment, auxiliary equipment, etc. These devices effectively sort out recyclable materials from renovation waste and facilitate its reduction, harmlessness, and resource utilization. Similarly, construction waste screening equipment is also a crucial tool in addressing the challenges of waste processing, as they categorize construction waste based on particle size through various screening principles. The application of these professional devices significantly promotes efficient handling and resource recycling of both renovation and construction waste.
Renovation waste treatment necessitates a complete set of specialized equipment to carry out collection, preprocessing, classification, screening, and recycling procedures. A typical configuration for such a system includes but is not limited to:
Zhongcheng Decoration Waste Treatment Equipment
1.Feeding Equipment:
Chain Plate Feeders: Used to uniformly and continuously feed renovation waste into the processing line.
2.Crushing Equipment:
Jaw Crushers: Primarily used to break down large pieces of hard waste like concrete and bricks.
Hammer Crushers or Impact Crushers: Further refine the renovation waste to an appropriate size for subsequent processing.
3.Screening Equipment:
Drum Screeners: Classify waste according to particle size.
Vibrating Screens: Also used for screening different-sized materials and separating them into various grades of aggregates.
5.Sorting Equipment:
Sorting Platforms: Employ manual or mechanical automation to identify and separate waste by material type.
Air Separators: Utilize aerodynamics to distinguish between lightweight and heavy materials, such as separating lightweight plastics and paper.
Magnetic Separators: Used to attract and separate iron-containing metals.
6.Conveying Equipment:
Belt Conveyors or Conveyor Machines: Transport materials between different processing stages.
7.Auxiliary Equipment:
Bucket Elevators: Vertical transportation of materials.
Bins: Storage for untreated or treated materials.
Electromagnetic Vibration Feeders: Precisely control the feeding speed and amount of materials.
Fans: Provide the necessary power source for air separation.
Centralized Electronic Control System: Achieves automatic monitoring and control throughout the entire production line.
This combination of equipment effectively separates recyclable materials like wood, metal, plastic, and glass from renovation waste while breaking down non-recyclables such as bricks and concrete into reusable building materials, thereby realizing the reduction, harmlessness, and resource utilization of renovation waste.
For construction waste screening, commonly used equipment includes:
Vibrating Screens: Commonly employed in construction waste processing, vibrating screens allow materials to pass through differently sized sieves based on their particle sizes, categorizing them into multiple levels such as coarse, medium, and fine aggregates.
Drum Screens: Rotary screening devices with sieves of varying aperture sizes; as the drum rotates, construction waste tumbles through the sieve holes, classified according to particle size, particularly suitable for screening larger particles and less prone to clogging.
Fixed Screens (e.g., Grid Screens and Bar Grates): Typically used in initial screening stages, grid screens often control feed particle size, whereas bar grates are better suited for screening coarser waste items like discarded bricks and concrete.
Disc Screen: This screening device utilizes centrifugal force and material-to-material collisions during rotation to achieve efficient and precise screening, suitable for primary selection of both construction and renovation waste.
Tumbler Screens (also known as Shot Blasting Screens or Oscillating Screens): They employ bouncing and rolling principles to separate materials of differing densities and particle sizes within mixed waste.
Considering the characteristics and processing needs of construction waste, selecting the right screening equipment is critical to achieving effective resource utilization and reduction of construction waste. Moreover, some screening systems may integrate additional technologies such as air separation and magnetic separation to more accurately isolate waste of different types and properties.
In summary, both renovation waste treatment and construction waste screening require a series of specialized equipment for collection, preprocessing, classification, screening, and recycling. Renovation waste treatment equipment encompasses chain plate feeders, jaw crushers, hammer/impact crushers, drum screeners, vibrating screens, sorting platforms, air separators, magnetic separators, belt conveyors/conveyor machines, bucket elevators, bins, electromagnetic vibration feeders, fans, and centralized electronic control systems. These devices work together efficiently to sort recyclable materials and crush remaining parts into recycled building materials, thus achieving waste reduction, harmlessness, and resource utilization.
Construction waste-specific screening equipment mainly consists of vibrating screens, drum screens, fixed screens (such as grid screens and bar grates), disc screens, and tumbler screens. Vibrating screens classify waste by particle size; drum screens are ideal for screening larger particles; fixed screens are often used at the preliminary screening stage; disc screens provide fine-grained screening; and tumbler screens separate materials based on density and particle size. Selecting appropriate screening equipment and combining it with technologies like air separation and magnetic separation can enable targeted, refined processing of construction waste, contributing to increased resource utilization rates and fulfilling waste reduction objectives.
