Decoration waste disposal requires a series of professional equipment to complete processes such as collection, pretreatment, classification, screening, and recycling. A complete set of decoration waste treatment equipment usually includes but is not limited to the following parts:

1. Feeding equipment:

Chain plate feeder: used to uniformly and continuously feed decoration waste into the processing line.

2. Crushing equipment:

Jaw crusher: used for initial crushing of large pieces of hard waste such as concrete, bricks, etc.

Hammer crusher or impact crusher: further finely crushing decoration waste to achieve a particle size suitable for subsequent processing.

3. Screening equipment:

Drum screening machine: Classify and screen garbage according to its particle size.

Vibration screen: also used to screen materials of different sizes and separate aggregates of different specifications.

4. Sorting equipment:

Sorting platform: manual or mechanical automation identifies and sorts out garbage of different materials.

Wind sorter: using aerodynamic principles to distinguish between light and heavy substances, such as separating lightweight plastics, paper, etc.

Magnetic separator: used for adsorbing and separating iron containing metals.

5. Conveyor equipment:

Conveyor belt or conveyor: Transport materials between various processing stages.

6. Auxiliary equipment:

Bucket elevator: vertically conveying materials.

Storage bin: stores materials that are awaiting processing or have already been processed.

Electromagnetic vibration feeder: precise control of material feeding speed and quantity.

Fan: Provides the power source required for wind selection.

Centralized electronic control system: achieve automated monitoring and control of the entire production line.

This set of equipment combination can effectively sort out recyclable materials such as wood, metal, plastic, glass, etc. from decoration waste, and also crush non recyclable parts such as bricks, concrete, etc. for the production of recycled building materials, thereby achieving the reduction, harmless and resourceful treatment of decoration waste.

The main equipment used for screening construction waste includes the following:

Vibration screen: Vibration screen is a common screening equipment in the process of construction waste treatment. It uses vibration to pass materials through different specifications of sieves, and divides construction waste into multiple grades according to particle size, such as coarse aggregate, medium aggregate, fine aggregate, etc.

Drum screen: Drum screen is a rotary screening device equipped with screens of different apertures inside. When the drum rotates, construction waste rolls inside the drum and passes through the screen holes, and is screened according to particle size. It is especially suitable for screening larger particles and is not easy to block the screen holes.

Fixed sieve: including grid sieve and bar sieve, mainly used in the initial screening stage. Grid sieve is often used to control the particle size of the feed, while bar sieve is suitable for screening coarse-grained waste with larger particle size, such as waste bricks and waste concrete in construction waste.

Disc sieve: This screening equipment achieves efficient and fine screening through the centrifugal force generated by the rotation of the disc and the collision between materials, and is suitable for primary sorting of construction and decoration waste.

Ballistic screen: also known as shot blasting screen or swing screen, uses the principles of bounce and rolling to separate materials of different densities and particle sizes from mixed garbage.

Taking into account the characteristics and treatment needs of construction waste, selecting appropriate screening equipment is crucial for achieving effective resource utilization and reduction of construction waste. In addition, some screening systems may also combine various technical means such as air separation and magnetic separation to more accurately separate different types and characteristics of waste.

Summary: Both decoration waste treatment and construction waste screening require a series of professional equipment for collection, pretreatment, classification, screening, and recycling. The decoration waste treatment equipment includes chain plate feeders, jaw crushers, hammer/impact crushers, drum screening machines, vibrating screens, sorting platforms, air separators, magnetic separators, conveyor belts/conveyors, bucket elevators, silos, electromagnetic vibration feeders, fans, and centralized electronic control systems. These devices work together to effectively sort recyclable materials and convert the remaining part into recycled building materials, achieving waste reduction, harmlessness, and resource utilization.

The specialized equipment for screening construction waste mainly includes vibrating screens, drum screens, fixed screens (such as grid screens and bar screens), disc screens, and ballistic screens. The vibrating screen is classified and screened according to particle size; Drum screen is suitable for screening large particle materials; Fixed screening is often used in the preliminary screening stage; Disc sieve can finely screen; Ballistic screens separate materials based on their density and particle size. Reasonable selection and combination of wind selection, magnetic separation and other technologies can target the fine treatment of construction waste, which is conducive to improving its resource utilization rate and achieving the goal of waste reduction
