ALLU’s new drum allows one screen to produce three different sizes

Screen manufacturer ALLU revealed is new ALLU TS drum assembly, which allows one unit to produce different product sizes, for the first time at Intermat 2015. Developed a few years ago for its compact machines – from 2 to 12 tonnes – the feedback from clients was so positive that the group has invested in developing the technology for the larger D series frames.

Screen manufacturer 2180 ALLU revealed is new ALLU TS drum assembly, which allows one unit to produce different product sizes, for the first time at Intermat 2015. Developed a few years ago for its compact machines – from 2 to 12 tonnes – the feedback from clients was so positive that the group has invested in developing the technology for the larger D series frames.

The core of the ALLU TS technology, which has a patent pending, is the blades that spin between the screening combs, with the size of the end product defined by the space between the combs. The fragment sizes can be changed by just repositioning the screening combs with three possible sizes: 16/32 mm, 25/50 mm and 35 mm.

The screening combs carry most of the material weight which means that the drums and bearings take less impact and load. According to ALLU, the construction is clog free which ensures good capacity even with wet materials.

There are seven different models of ALLU TS drums available, for 16 – 45 t excavators between 16 and 45 tonnes and 7 – 30 t wheel loaders between 7 and 30 tonnes. The drums are available with two different blade types: standard blades and axe blades for when crushing is needed.

    The latest developments in drilling rigs can help boost efficiency in quarry producion applications - Mike Woof reports. Efficient drilling and blasting operations can have a huge impact on production costs in quarrying. Accuracy of hole direction and depth, as well as optimum blast design and explosives use, are critical for efficient blasting work. Ineffective blasting can result in high quantities of fines of low commercial value as well as over-sized material requiring secondary breaking. This impacts o

    New innovations are underway that will help optimise rock crushing and screening operations and boost quarry efficiency overall - Mike Woof writes. Quarrying is a tough industry that provides enormous challenges to equipment providers as machines and technology have to be rugged, durable and productive. Cutting the cost of production while optimising output has been a major target for suppliers, with new technologies playing an increasingly important role. Taking the long view with regard to increased qu

    Metso's Indian-manufactured Nordwheeler portable crushing and screening plants are said to be playing an important role in a number of road and other construction infrastructure projects in Asia and Africa. During a short period of time, Metso has sold over 30 portable Nordwheeler plants to Asian and African-based aggregates producers. The plants are manufactured in Metso's factory in Bawal, India – earlier this year reaching the milestone of 1,000 Indian-manufactured portable plants.
