Adjustable Screening Bucket

Precisely Adjustable Discharge Size Adapts to Multiple Scenario Requirements

The core competitiveness of the Motek screening bucket lies in its flexible adjustment of the discharge size. It can be precisely adjusted from 8mm to 75mm to meet specific operational needs, covering a full range of scenarios, from fine particle screening to bulk material classification. For fine aggregate screening (such as sand purification and powder classification), the gap can be reduced to 8-20mm; for construction waste sorting and coarse ore classification, the gap can be adjusted to 45-75mm.

High-efficiency screening design ensures both productivity and quality

This screening bucket utilizes a multi-level screen structure and optimized material flow design to effectively improve screening efficiency and material handling capacity. Standard models offer a processing capacity of 15-40 tons/hour, suitable for excavators or loaders in the 20-45 ton class. The screen is made of high-manganese steel or polyurethane, and features a special weaving process or punching design, resulting in high strength and wear resistance. It also ensures a screen penetration rate of over 90%, minimizing material clogging and residue. Furthermore, the equipment is equipped with a high-frequency vibration mechanism, whose frequency can be flexibly adjusted according to the material's moisture and viscosity (typically 1500-2500 vibrations/minute). This effectively solves the screening challenges of wet and sticky materials (such as clay and sludge mixtures), ensuring uniform particle size and low impurity content after screening.

Durability and Low Maintenance

The Motek screening bucket's structural design and material selection balance durability and cost-effectiveness. The entire frame is welded from high-strength steel. Key stress-bearing areas are reinforced with thickened sections and rounded corners for excellent impact resistance, making it suitable for high-intensity screening of complex materials such as mining and construction waste. The screen features a quick-release mechanism, allowing a single person to replace it in less than 30 minutes. It supports flexible interchange of screen materials (metal, polyurethane, and nylon) to meet diverse material screening needs. Consumable parts (such as vibration motor bearings and seals) are sourced from internationally renowned brands, extending their service life by over 30% compared to the industry average. Multiple access points ensure routine maintenance (such as lubrication, cleaning, and component inspection) without disassembling the main structure, further reducing maintenance time and costs.

Flexible Installation, Outstanding Maneuverability and Adaptability

Compared to traditional fixed screening equipment, the Motek adjustable screening bucket offers superior maneuverability and adaptability. Using standardized connection interfaces, the device can be quickly adapted to mainstream excavators, loaders, and other construction equipment. Installation takes less than 40 minutes, requiring no modifications to the main machine. The equipment is lightweight (1.5-5 tons, depending on the model), placing no additional strain on the main unit. It also occupies a small footprint, with a minimum operating radius of only 2.5 meters, making it suitable for flexible operation in confined environments such as narrow urban construction sites and underground mine tunnels. Furthermore, the equipment can be quickly relocated with the main unit, eliminating the need for large transport vehicles and significantly reducing relocation costs and time.

Construction Waste Recycling

In urban demolition and renovation projects, the sorting and resource utilization of construction waste (such as concrete blocks, bricks, and waste wood) are key requirements. The Motek screening bucket can be directly mounted on an excavator to screen construction waste on-site. By adjusting the discharge size (e.g., 20-50mm), recycled aggregates such as concrete fragments and bricks can be separated for use in the production of recycled concrete, permeable bricks, and other building materials. By adjusting the screen gap to 8-16mm, fine sand can be screened for use in roadbed backfill or mortar preparation. Large impurities (such as scrap rebar and wood) on the screen can be manually sorted and recycled. This process achieves on-site treatment and recycling of construction waste, reducing not only removal costs (saving 50-80 yuan per ton) but also landfill space, complying with environmental protection policies.

Material Grading in Mines and Quarries

In mining and quarrying operations, the Motek screening bucket can be used for coarse and intermediate grading of ore, replacing traditional fixed screening equipment. In metal mines (such as iron and copper), a 50-100mm screening gap can be used to filter out high-quality ore, improving beneficiation efficiency. Furthermore, the screening bucket can be moved with the mining face, eliminating the need for a fixed screening station. It is particularly suitable for the flexible production needs of small and medium-sized mines or open-pit mines, significantly shortening the process time from mining to processing.

Road and Water Conservancy Project Construction

In road and water conservancy projects, material screening is essential for multiple processes, including roadbed preparation and building material preparation. During road base construction, the Motek screening bucket can screen soil and rock. Adjusting the screen mesh to 30-80mm allows for the selection of rock that meets gradation requirements for roadbed filling, ensuring compaction and stability. In asphalt concrete preparation, fine screening at 10-20mm yields qualified fine aggregate, ensuring the gradation accuracy of the asphalt mixture. In water conservancy projects (such as dam construction and river dredging), the screening bucket can be used to separate river silt from sand and gravel. Using a 8-16mm screening gap, the sand and gravel aggregates are separated from the silt, enabling resource recovery. The silt can also be dewatered and used for land reclamation, balancing project construction with ecological protection.

Applications in Agriculture and Environmental Protection

In agriculture, the Motek screening bucket can be used for organic fertilizer production and straw crushing and screening. Adjusting the screen mesh to 8-16mm can screen out mature organic fertilizer particles and remove impurities and uncomposted bulk. For straw return to fields, the device can be crushed before screening to separate fine straw fragments, improving return efficiency. In environmental protection, the device can be used for household waste sorting and sludge treatment. At household waste treatment plants, a 20-50mm screening gap can separate recyclables such as plastics and metals from inert materials such as slag. In sludge treatment projects, high-frequency vibration and 5-10mm screening can separate sand and gravel impurities from sludge, reducing the difficulty of subsequent dewatering.

Landscape and Municipal Engineering

In landscape and municipal engineering, the Motek screening bucket meets material handling needs in landscape construction, site leveling, and other areas. In landscape construction, a 10-30mm screening gap can separate fine soil and sand and gravel mixtures for lawn paving and flower bed construction. Adjusting the screen gap to 50-100mm separates landscaping gravel and pebbles for trail paving and water features. In municipal projects (such as pipeline laying and site renovation), this screening bucket can screen excavated earth: qualified soil is separated for backfill, while large rocks are crushed and reused, reducing the amount of purchased earthwork and lowering project costs. Furthermore, in urban river desilting operations, screening can separate construction waste and sand and gravel from the silt, enabling the separate processing of desilted materials.
