Screening buckets are attachments fitted to excavators and loaders. They act as multi functional tools which can be ideal for separating materials, which can be anything from top soil, construction waste, crushed aggregates, turf, roots, or compost.
Screening buckets can be used for primary selection and to separate natural material, or material obtained after any crushing or other operations. These buckets can have screens of different configurations and this will depend on the particular requirements at any job site. Screening blades that have a spacing of 15 to 75 mm will screen material from 0 to 70 mm. These buckets are attached to the loaders or excavators or other equipment and will be allowed to function through the use of hydraulics. It is fairly easy to change attachments on these types of construction equipment and this makes it easy for operators to change the function of their machines, and even the size of screens in a short period of time. It adds to the versatility of the equipment.
Applications that require the need of these buckets can be the screening of topsoil when a landscape is being prepared in large gardens or sports fields. They can be used to screen any material that has been excavated for trenches for laying pipelines and cables so that backfilling and padding is easily carried out. They can be used to mix and aerate materials that can assist in the composting of soil to create a soil with high nutrition. In industries, they will be used to separate raw materials and can easily do this even with materials that are lumpy or wet. Screening buckets are extensively used on construction sites to separate construction waste so that the fines are separated before the coarser material is sent for reuse through crushing.
When you require separating stones, stumps, and roots from excavated material, these buckets can make the work that much easier. These buckets are often used in conjunction with buckets that allow the operator to crush material, while at the same time reducing crushing time, as fines are already separated out and do not impose any load on the crushing attachment. You will find these buckets in use for the cleaning of beaches, and to allow for the selection of pebbles to be installed in waterways.
Screening and crushing buckets can go a long way in reducing the costs for material and their transport, as they facilitate the recycling of materials on any site. These buckets can have rotators that move in both directions and this action helps to sieve material. Larger particles remain within the bucket and are disposed off separately after the sieving operation is completed. These buckets are available in many different sizes and with a varying number of screens.
Screening buckets have seen wide use in demolition jobs, in quarries and when rocky ground needs to be reclaimed. The buckets can also have blades that can rotate and act to further crush or shred the excavated material.
