Application Scenarios of Sorting Grabs for Excavator Attachments

### In the Field of Building Demolition and Construction Waste Treatment

- Sorting of Materials after Demolition: After the completion of building demolition projects, there are usually large amounts of mixed construction waste on site, such as bricks, concrete blocks, steel bars, and wood. Installed on excavators, sorting grabs can, with their flexible grasping actions, sort out recyclable steel bars, intact bricks, etc. according to the characteristics of different materials and place them in corresponding collection areas. This facilitates subsequent recycling or reuse, helps improve the resource recovery rate, and reduces the environmental pollution caused by construction waste.

- Debris Clearance and Classification: For building debris formed after disasters such as earthquakes and fires, sorting grabs can reach deep into the debris, grasp various buried or piled-up building components and sundries, and distinguish valuable items (such as undamaged metal doors and windows, etc.) from waste that needs to be uniformly disposed of later. This enables the debris clearance work to be carried out more efficiently and orderly, accelerating the pace of post-disaster reconstruction.

### In the Mining and Ore Processing Industry

- Ore Sorting and Screening: At the mining site, the freshly mined ores are often mixed with a lot of waste rocks, soil, and other impurities. Sorting grabs, working in coordination with excavators, can sort out high-quality ores according to the differences in appearance and texture between ores and impurities, transport them to specific transportation or processing areas, and separate waste rocks that do not meet the grade requirements at the same time, thus improving the grade of the ores entering the beneficiation process and reducing the cost and difficulty of subsequent ore dressing and processing.

- Tailings Treatment: For the tailings remaining after ore dressing, sorting grabs can conduct secondary sorting and recovery of the small amounts of valuable minerals still remaining in them. They can also classify and sort the tailings according to different particle sizes and compositions, so as to realize the rational reuse of resources or environmentally friendly treatment of tailings. For example, tailings can be used in the production of building materials and other fields to maximize the comprehensive utilization of resources.

### In the Port and Logistics Warehousing Industry

- Sorting and Loading/Unloading of Bulk Cargo: At port terminals, in the face of large quantities of bulk cargo such as coal, ores, and sand and gravel, sorting grabs installed on excavators used for port operations can sort and grasp the cargo according to requirements such as particle size and type, load the cargo that meets the specifications into corresponding transportation tools (such as cargo ships, trucks, etc.), or sort out foreign objects (such as large pieces of debris, etc.) mixed in it, ensuring the quality and efficiency of cargo loading and unloading and meeting the demanding logistics operation needs of ports.

- Warehousing Goods Arrangement: In large logistics warehousing centers, sorting grabs can assist in sorting and arranging some large and irregularly shaped goods. For example, when it is necessary to readjust the placement positions of goods or classify and return different batches and specifications of goods to their designated locations, sorting grabs can quickly grasp the goods and accurately place them in the specified places, improving the utilization rate of warehousing space and the convenience of goods management.

### In the Agricultural and Horticultural Fields

- Material Handling and Sorting: In agricultural production, sorting grabs can be used to handle and sort various agricultural materials. For example, they can transport harvested bundles of crops (such as wheat straw, rice straw, etc.) from the fields to designated storage locations and sort them according to conditions such as dryness and length, facilitating subsequent processing (such as making feed, weaving, etc.). In horticulture, they can help sort stones, plant residues, etc. in garden construction, clear the site and sort materials for landscape creation, improving work efficiency.

- Harvesting and Sorting of Agricultural Products: For some large-sized and relatively hard agricultural products (such as pumpkins, winter melons, etc.), sorting grabs can gently grasp them from the vines and can also conduct preliminary sorting according to characteristics such as the size and maturity of the fruits, reducing the physical labor consumption in the manual harvesting process and ensuring the quality and efficiency of agricultural product harvesting. This is especially applicable to large farms with large areas of cultivation.

### In the Municipal Engineering and Environmental Sanitation Field

- Sorting of Road Construction Materials: During the construction process of municipal roads, sorting grabs can sort the base materials of roads (such as crushed stones, sand, etc.), remove particles that do not meet the particle size requirements, and ensure the quality of road construction materials. Meanwhile, during road repair and cleaning, they can grasp broken road materials and debris, distinguish the reusable parts (such as intact bricks, etc.) from non-recyclable waste, which is conducive to saving construction costs and environmental protection treatment.

- Garbage Disposal and Classification: In urban waste treatment plants, sorting grabs can participate in the classification work of mixed waste such as household waste and construction waste, sort out different types of waste (such as metal products, plastic products, biodegradable organic matter, etc.) and place them in corresponding treatment areas, improving the refinement degree of waste treatment and promoting the effective implementation of urban waste classification policies, and helping to create a clean and environmentally friendly urban environment.

### In the Industrial Manufacturing and Disassembly Field

- Sorting and Assembly of Parts: In some large industrial manufacturing enterprises, especially factories that produce heavy machinery and large equipment, sorting grabs can assist in sorting and transporting various large and heavy parts. According to the production process and assembly requirements, they can accurately grasp the parts and place them in corresponding assembly positions, improving the assembly efficiency and reducing the safety risks that may be brought by manual handling. During equipment disassembly and recovery, sorting grabs can successively grasp different components on the equipment, facilitating subsequent classification treatment and resource recovery and reuse.

- Treatment of Waste Metals: For waste metal recycling enterprises, sorting grabs can sort and grasp waste metal scraps according to factors such as the types of metals (such as steel, copper, aluminum, etc.), shapes, and sizes from piles of waste metal scraps, collect metals of the same type together, facilitating subsequent recycling links such as melting and processing, and improving the value and efficiency of waste metal resource recovery.
