Toyo says that its hydrostatically driven submersible pumps provide performance benefits over rival electrically driven units. Features include robust construction and special metallurgies coupled with hydraulic motors that deliver high torque at low speed and which can handle tough applications. With the hydraulic piston motor featuring adjustable rotation speed, the capacity and the pressure supplied by the pump can be adapted to application and site requirements. The motors can cope with slurrie

Innovations in drilling and blasting and crushing and screening are bringing major economies of scale to aggregate production operations. Drilling and blasting is an area where new technology is offering major saving to quarrying companies. This is another important factor in the quarrying process, as inefficient drilling and blasting can have major financial repercussions.

The first motorway connecting the cities of Hyderabad-Bangalore will be approximately 600km long, with three lanes in both directions. It will represent an important change in India as the country will benefit from a fast and greater flow of communication, transportation and commerce networks, which up until now have been carried out mainly by sea.

MB S.p.A. of Italy has launched the first of a new generation in its bucket crusher range following the successful launch of the units in 2007. According to the company, which currently exports to more than 100 countries, applications for MB bucket crushers, which fit a variety of excavator sizes (and which also include an iron separator) are many. They include demolition, general construction, excavation work, earthmoving, quarry and mines, vineyard deep ploughing and environmental remediation. However,

Mexico-based Grupo Pinfra was one of the country's first aggregate producers to invest in mobile crushing and screening equipment. Twenty years on, the company is still confident that mobile equipment is key to meeting demand and has just expanded its fleet. In 1991, Pinfra took delivery of two Metso Minerals Lokotrack LT125 mobile crushers and these have now clocked up 30,000 working hours. Nonetheless, there is still plenty of life in these machines and while the newly acquired LT140 jaw crusher takes

Conveyors specialist Superior Industries is now offering virtual welder training at its Welding Training Centre. The VRTEX 360 is a virtual reality arc welding training system from Lincoln Electric and allows Superior's welders to practice techniques in a simulated environment. The aim is to boost welding skills while reducing material waste. The combination of a realistic welding puddle simulation and arc welding sounds tied to the welder's movement is said to provide realistic training. The system scores

A wide variety of new equipment and technology to assist production at asphalt plants is about to be launched onto the market, while asphalt producers are continuing to look at greener working practices. Guy Woodford reports Lintec, in partnership with Loesche, recently created what they say is the world's first containerised Coal Mill Plant for independent coal dust supply at the jobsite which offers mobility and high economic efficiency through the substitution of gas or oil with coal. The mobile co

A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

Work is continuing to upgrade Chhatrapati Shivaji International Airport (CSIA), India's largest airport in Mumbai, the country's largest city.
