Under the current global advocacy of sustainable development, material recycling is increasingly critical for saving resources and reducing environmental impact. Motek has been deeply involved in the industry for nearly 20 years, focusing on the research and development and manufacturing of various machinery attachments, and plays an indispensable role in the field of material recycling. Its jaw crusher bucket, screening bucket, mixing head and other attachments, with advanced design and excellent performance, provide efficient solutions for the recycling of various materials.
1.Motek machinery attachment types and working principles
Jaw crusher bucket
The jaw crusher bucket is suitable for 10-40 ton excavators, and its working principle is a crank extrusion type. The hydraulic motor drives the eccentric main shaft through the spline shaft, and the eccentric shaft drives the movable jaw to move up and down. When the movable jaw rises, the angle between the top plate and the movable jaw increases, the wedge-shaped space of the feed port increases, and large pieces of material enter under the action of gravity; when the movable jaw plate approaches the fixed jaw plate, the wedge-shaped space of the feed port becomes smaller, and the material is subjected to multiple crushing such as squeezing, rubbing, and grinding; when the movable jaw descends, the angle between the top plate and the movable jaw decreases, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring, and the crushed material is discharged from the lower opening of the crushing chamber. This crushing method can effectively crush large pieces of material such as construction waste and stone, and provide materials of suitable particle size for subsequent recycling.
Screening bucket
The screening bucket can be flexibly adapted to excavators and loaders. It screens and grades materials through a specific screening structure. During the working process, after the material enters the screening bucket, the movement of the bucket and the internal screening components, such as the screen, separate the materials of different particle sizes. This attachment can be widely used in screening and crushing projects such as pipeline fine soil backfilling, screening and loading coal sludge, asphalt crushing, contaminated soil treatment, and organic fertilizer compost aeration. It can accurately separate materials that meet different needs and improve the utilization efficiency of materials.
Sludge solidification mixing head
The sludge solidification mixing head adopts a Y-shaped design, which is easier to enter the soil in hard geology, and has a two-way rotation function. It is not easy to be sucked by mud during deep mixing and is easy to pull out. The distance between the small angle between the left and right reamer blades is only 1 cm, ensuring that there is no blind spot in mixing. When working, the automatic torque adjustment valve can automatically adjust the power output of the two hydraulic motors located in the roller according to different working conditions to ensure efficient and stable mixing operations. At the same time, the roller speed and temperature sensors and oil leakage detection sensors allow the operator to accurately control the operating status of the equipment in the cab. It is mainly used to mix soil solidifiers with silt on site to achieve stabilization of silt for subsequent use. Specific application scenarios in material recycling.
2.Construction waste treatment
A large amount of construction waste will be generated during urban construction and renovation. Motek jaw crusher bucket can be directly installed on the excavator to crush large pieces of concrete, bricks and other construction waste into smaller particles. The crushed materials can be further screened by the screening bucket to separate aggregates of different particle sizes. These recycled aggregates can be used to make recycled bricks, road base materials, etc. For example, in some old city renovation projects in some cities, Motek crushing and screening attachments are used to process the construction waste generated by the demolition of buildings on site, part of which is used as backfill materials for site leveling, and part is made into recycled building materials, which greatly reduces the amount of construction waste transported out and the demand for natural aggregates, and realizes the resource recycling of construction waste.
Waste treatment in mines and quarries
In mining and quarrying operations, a large amount of tailings and waste stones are generated. The jaw crusher bucket can crush these large pieces of waste, and the screening bucket can screen and grade the crushed materials to realize the secondary utilization of mine resources. Some waste stones can be used as construction sand, road paving materials, etc. after processing. For some tailings containing valuable minerals, after crushing and screening, they can be further processed for mineral processing to extract useful minerals, improve resource utilization, and reduce the impact of mine waste on the environment.
Soil remediation and improvement
In the treatment of contaminated soil and soil improvement projects, screening buckets can be used to screen contaminated soil and remove large impurities in it to prepare for subsequent soil remediation. The sludge solidification mixing head can mix and stir the soil solidifier with contaminated sludge, soft soil, etc. on site to achieve soil stabilization and remediation. Through solidification technology, sludge is converted into stable solid matter for subsequent treatment and utilization. For example, in some soil remediation projects around rivers and lakes, the mixing head is used to mix sludge with solidifier to form a composite stable base, which not only solves the problem of sludge accumulation, but also improves the soil structure, which can be used for subsequent land development or ecological restoration.
Resource recycling
In the fields of industrial waste and waste material recycling, Motek machinery attachments also play an important role. The crushing bucket can crush large pieces of waste such as scrap metal and wood, which is convenient for subsequent classification, recycling and reprocessing. The screening bucket can screen the recycled mixed materials, separate the components of different materials, and improve the purity and utilization value of the recycled materials. In the scrap steel plant, the crushing bucket crushes the discarded steel parts into suitable sizes for smelting; in the recycling of waste wood, the crushed wood can be used to make artificial boards, biomass fuel, etc.
Motek machinery attachments effectively crush, screen and process various materials, converting the originally discarded or underutilized materials into reusable resources, significantly improving the utilization rate of resources. It reduces dependence on the exploitation of natural resources and helps protect natural resources and the ecological environment. Taking the treatment of construction waste as an example, the construction waste that was originally discarded is processed by the attachments and converted into a large amount of recycled building materials, realizing the recycling of resources and reducing the consumption of new sand and gravel and other resources in the construction industry.
3.Reducing costs
On the one hand, using these attachments to directly process materials at the construction site reduces the cost of material transportation. There is no need to transport a large amount of waste to a special treatment site, and the cost of purchasing new materials is also reduced. For example, in road construction, recycled aggregates made from recycled construction waste are used to replace some natural aggregates, reducing material procurement costs. On the other hand, work efficiency is improved and labor costs are reduced. For example, the jaw crusher bucket adopts a drive method in which the international first-line brand hydraulic motor is directly connected to the drive shaft. It has strong crushing power and stable performance, which can greatly reduce the cost of manual crushing of materials. Promote the development of environmental protection Reduced the discharge and accumulation of waste and reduced the risk of environmental pollution. In soil remediation and sludge treatment, the application of accessories such as mixing heads has achieved harmless and stabilized treatment of contaminated soil and sludge, improving soil quality and water environment. For example, in the contaminated soil treatment project, the coordinated use of screening buckets and mixing heads effectively repaired the contaminated soil, reduced the impact of harmful substances in the soil on the surrounding environment, and promoted the development of environmental protection.
In summary, Motek machinery attachments are widely used in many fields of material recycling, from construction waste treatment to mining waste utilization, from soil remediation to resource recovery. By improving resource utilization, reducing costs and promoting environmental protection, they have made important contributions to sustainable development. In the future material recycling industry, they are expected to continue to play a greater role and help the industry continue to progress.
