Screening buckets

Remu screening buckets have a long history dating back to the late eighties. Recent models have gone through rigorous development. Our customer focused development process keeps us on track and ensures continuous improvement which helps us to create products which solves real material processing problems and fulfil customers' requirements.

Applications

What you can process with screening bucket?

Preparation of topsoil, composting, and recycling are the most common applications of screening buckets. The screened fraction obtained can be classified as a clean, high-quality soil free of oversize stone, etc. Buckets can also be used to mix sand, clay and compost to achieve the desired consistency required for a specific use.

Screening organic waste
Screening organic waste

Screening buckets can process various organic materials. This bucket in Spain is used for screening and crushing biomass which is a waste stream output from the olive oil production process.

Material: industrial waste stream including fruit stones, sticks and leaves
Objective: Crush & screen the material for feeding biomass boilers
Bucket model: EE4290
Blade model: 4304
Blade thickness and spacing: 16mm /24mm

Topsoil
Screening Topsoil

Preparing topsoil with screening buckets has long been a common application in northernly countries and is becoming more frequent in other areas as well. The benefits of processing materials onsite instead of transporting them, is also recognized in the USA. Producing topsoil is one of the most common applications. With our blade screen technology you can separate stones, wooden sticks and other unwanted particles from the soil. Blades also mince up the lumps in the material. 

Material: topsoil
Objective: Separate the stones and sticks and other oversized particles to prepare the topsoil for landscaping. Maximum particle size 28 mm
Bucket model: EP 4150
Blade Model: 2001
Blade thickness and spacing: 16mm/34mm

Aerating and Mixing Compost
Aerating and Mixing Compost

Mixing and aerating organic waste piles will speed up the composting process. More aggressive blades, such as screening-crushing blades, break the material into smaller particles to catalyze the process. Composition can vary from very moist to dry, depending on the type of material and how advanced the composting process is. In the early stages of the process, a bucket with very large gaps between the blades can be used to mince up particles and aerate the material whilst later in the process the compost can be screened using a bucket with narrow blade spacing between the screening blades to separate any remaining oversized particles from the end product. The screening bucket are compact and are easy to bring inside any composting installations.

Material: Dried and composted sewage sludge
Objective: Remove remaining oversized particles from composted material
Bucket model: EP 4150

Demolition waste recycling

Recycling demolition waste

Onsite processing of demolition waste reduces the amount of material sent to landfill. The PD 3160 was used at the demolition site of an old hospital in the UK.

Material: Gravel, constructions waste
Objective: Separating oversized particles and preparing the material for reuse onsite
Bucket model: PD 3160
Blade Model: 4304
Blade thickness and spacing: 16mm/24mm

Soil remediation
Coal processing

Screening buckets with aggressive blade models can easily process coal and break it down to a smaller particle size. In the UK coal was processed with the EE 4220, which is the second largest of our models of bucket.

Objective: screening particles size for further use
Bucket model: EE 4220
Blade model: 4311
Blade thickness and spacing: 16mm/ 74mm

Gypsum Processing
Gypsum Processing

The recycling of gypsum board often requires, that the material is first crushed down to a smaller particle size. In Washington, USA, gypsum is crushed with a Remu XO2150 bucket  equipped with screener-crusher blades. The crushed material is then reused as an agricultural soil additive.

Objective: Crush recycled gypsum board for further use
Bucket model: XO2150 with SC module
Blade model: 2304
Blade thickness and spacing: 10 mm/ 20 mm | 3/8"minus

Soil stabilization
Soil stabilization

Soil characteristics can be enhanced to meet the required engineering specifications by adding stabilizing agent like fly ash, lime fly ash, cement or other stabilizers. With our screening buckets the stabilizing can be done on-site by mixing just the right amount of stabilizer to the soil.

Operation principle of shaft screens

REMU screening buckets have between 2 and 4 rotators powered by hydraulic motors. The spinning motion of the rotators and the carefully designed shape of the blades create movement that effectively separates the fine material, which drops through the bucket, and oversized particles, which remain inside the bucket. Because of this up and down movement, even material that is moist and thus hard to process with vibrating or sifters screens, is easy to process with the Remu blade screens.

Blade designs

Our blade designs can be divided into two groups:

  • Screening blades genuinely the materials without breaking up large particles thus avoiding them passing into the screened product.
  • Aggressive blades are designed to mince and break up materials like glass, roof tiles, root lumps

Counter blades

Comb counter blades are designed purely for screening and separating the material while aggressive counter blades are used for rough material and to help mince up the particles and lumps.

Cleaning scrapers

Blade screen technology is the best choice for moist materials. Rotating blades make the material move up and down while cleaning scrapers, constantly cleaning sticky material off the shafts.

FAQ

Q&A on our Screening Buckets

How much material you can load into the bucket?

REMU screening bucket can be loaded fully which gives you more capacity at each scoop whilst trommel style buckets can be only filled to 1/3 of the bucket volume.

Multiple series for each unique application

Screening Bucket Series

STANDARD SCREENING BUCKETS

Designed to maintain an optimum ratio of bucket mass to bucket volume, we make the most of the lifting capacity of the machine to load more material. Buckets can be fitted to excavators, wheeled loaders, tractors, and telehandlers of various sizes.

CROSSOVER BUCKET

The crossover bucket is a totally new concept for the attachment sector: one bucket frame with multiple work modules enables a quick transition between different jobs. This is the perfect choice if you process several different materials.

EXTRA STRONG SCREENING BUCKET

Overcoming the challenges of pipeline projects, trench backfilling and other demanding heavy-duty applications. These buckets have a high strength frame that can take a hammering. The buckets can execute demanding applications where an extra strong structure is required.
