Screening buckets - Excavator attachment for screening, mixing and processing

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

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

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

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

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 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.
