ALLU Group

Paving the way for the future of demolition, ALLU's Screener and Crusher Buckets for 10 to 38 Ton machines are designed to be adjustable for 13 different discharge sizes. Place two solutions side by side provides demolition sites with increased capacity, saving the customer five times over, which saves time and money giving you a solution for your business.

The advantage of using both solutions side by side is increased capacity and resumed wear and tear for sites with five times the production rate. First launched in Finland and tried and tested with Nordic countries which are known for harsh environments, when a customer in Finland tested the crusher and screener side by side, it became a game-changer for demolition. A sieve and crusher bucket chain for handling powdered concrete. At this site, 85% percent was screened and also partially crushed through a screener crusher bucket (Allu Transformer DH 3-17 XHD) and only the excess very hard material was crushed with a crusher bucket (Allu Crusher AC 25-37). The company expects this percentage to be higher in less harsh environments.

“The demolition concrete was treated after pulverization with two ALLU’s The excess obtained from the screener crusher bucket visible at the front was crushed to a 90 mm fraction with a crusher bucket. Thus, a total of about 5,000 tons passed through two buckets. The demolition of two two-story (lower floor underground) residential buildings produced a total of about 5,000 tons of concrete. The maximum fraction size achieved in the pulverization was 400 millimeters, which is a maximum good input feed size for the Allu crusher bucket.  The jaw is reversible, which enables fast and easy recovery of from possible blockages, in my 30 years in the industry this has changed the direction for demolition.”
Ilpo Ellonen, Regional Sales Manager at Allu Finland Oy

The demolition phase of the demolition yard site took a total of three weeks. At the time of the visit, approximately 600-700 tons of concrete waste were still untreated. In the next or fourth week, there was still a run-off of crushed concrete for use at the bottom of the forest road. The purpose of the entire process is to recycle concrete waste at ALLU into stone aggregate for reuse, which replaces the need to use virgin aggregate providing environmentally sustainable solutions.

Fine material by Screening

The throughput of material from the screener crusher bucket is many times higher than with the crusher bucket, so the goal is to get the fines out as accurately as possible by screening so that the amount of material to be crushed is kept to a minimum and the customer was very surprised the blades were hardly worn during this tonnage.  The screener crusher bucket has a basic block-type drum with a 75mm hammer configuration. In the future, it is worth examining carefully whether there is an economic justification for using more durable and expensive hammers. If the hammers cost half as much, then they should also reach at least double their service life. The replacement of hammers in Allu is fast, so it is handled conveniently on-site conditions.
