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

Doosan’s new DX140LCR-5 15tonne reduced tail swing crawler excavator is powered by the Perkins 1204F engine, which combines reduced fuel consumption with the power and torque of larger engines with a smaller displacement. The new Perkins 1204F engine provides a 6% increase in power with an output of 85.9kW at 2,000 rpm and a 3% increase in torque. Swing torque has also been boosted by 28%. Trouble-free operation is guaranteed by meeting Stage IV emission regulations without the need for a diesel parti

BAV Crushers offers a variety of crushing attachments and is highlighting those for the same weight range of carrier excavator, roughly based on 3-6tonne operating weight, from each of its three core products. These are the BAV Alligator jaw pulverisers, for ripping up of slabs, demolitions of walls, cutting of rebar and primary crushing; BAV-CB crusher buckets, for reducing general, on site rubble, such as bricks, blocks, concrete and even rock, to a re-useable aggregate,and BAV-RS rotary screening bucket

McCloskey International is introducing the new R155 Dual Power mobile screener to its line-up of screening equipment. Designed for maximum uptime on the job, the company says the R155 Dual Power can switch easily between the two sources of energy. Easily connected to external electricity supply sources, the Dual Power R155 is adaptable, and able to work in a variety of sites around the world. The R155 is a member of the durable scalping R Range and boasts the 2.5m transport width.

Highly innovative, LINTEC’s new LEP 95 system is a new, patented warm mix asphalt solution. This can be configured to produce both hot and warm mix asphalt depending on demand at the job site. A major reduction in energy consumption and emissions can be achieved by the LINTEC system working in a temperature range of 95°C-100°C. This unitcan be fitted to new or existing plants and is said to produce a smooth and stable foam for an optimum mixing result at low temperatures, while it is reliable and has low ma

Developed by Ammann, the new ARX 90 and ARX 110 tandem rollers are available in both Tier 4Final/Stage IV variants for use in Europe and North America, as well as Tier 3 versions for use in lesser regulated markets. These high performance units are the first Ammann vibratory rollers to feature oscillation. This system cuts out around 90% of the vibrations to surroundings from conventional vibratory systems. The new rollers combine the oscillating, back-and-forth-movement of the drum with a constant static l

The new L45H and L50H wheel loaders from Volvo Construction Equipment are well balanced machines, built to a solid design that ensures the strongest performance even in confined jobsites. The H-series wheel loaders have Volvo’s Torque Parallel (TP) linkage to deliver high breakout torque and excellent parallel movement throughout the lifting range. A long wheel base, low center of gravity and good weight distribution give the machine superior stability on rough and uneven terrain. A robust, compact d

CONTROLS says it is offering a new system that provides more accurate testing of concrete and cement. The AUTOMAX E-Modulus can be used for both the standard failure test and the determination of the Modulus of Elasticity. This modulus is a key parameter to verify the behaviour of building structures under load, such as in seismic areas or for high buildings. This determination is performed conforming various national Standards as DIN 1048/1, ASTM C469, BS 1881:121, ISO 6784, UNI 6556. The accuracy of the c
