Large mobile order cements supplier relations with Japan

Part of the renowned Fujisaco group, the Showa Corporation has been a Sandvik customer for five years, purchasing a variety of Sandvik drill rigs, breakers and medium range mobile crushers and screens. Now it is also Sandvik?s first customer in Japan for the acclaimed U-440 range of tracked crushers.

Mr Yamanoi, the owner of the Showa Corporation, is one of the biggest quarry owners in Japan, with 10 different sites and more than 500 employees.

He has been a loyal Sandvik customer for the past five years and has now chosen to partner with Sandvik on the processing power of Sandvik?s productive U-range of mobile crushers.

Yamanoi chose this range of larger mobile equipment because of its proven high performance and ability to deliver a consistent high quality end product. Because Yamanoi and his companies have a reputation for being among the most forward thinking and innovative concerns in Japanese quarrying, the processing power of the Sandvik U-range of tracked crushers has provided the Showa Corporation with the perfect solution for its stringent crushing requirements.

Discussions between the Showa Corporation and Sandvik began in late autumn 2011, when Hiroshi Kezuka, Sandvik?s regional product line manager for mobile crushers and screens and Peter Delbrant, the product line manager for the U-range crushers, met with Yamanoi. As a result of this meeting Yamanoi placed an initial order for eight mobile crushing and screening units. The order comprised two sets of equipment, each consisting of a UJ440i jaw and US440i cone crusher complete with hanging screens, plus a UH440i cone and QA450 triple deck screener.


A key piece of equipment for the successful operation of each crushing and screening train is the UJ440i jaw crusher. This state of the art machine maximises production through its class leading feed opening, which coupled with a hydraulic close side setting enables rapid changes through push button operation, further enhanced by integral intelligent operation.

The heavy duty crusher utilised on the UJ440i is capable of handling any type of hard rock in any climate, including the most extreme weather conditions, when fitted with an optional engine pre-heater. Quick set-up time and site to site transportability are integral design features that ensure the unit is able to rapidly process materials in any location.

Both crusher and unit are manufactured to the highest quality using Sandvik components, meaning the number of spare and wear parts that need to be stocked is minimised. Trouble-free and safe operation is ensured thanks to automatic and continuous monitoring of the production process by the in-built intelligence control system.

The Sandvik UH440i and US440i tracked cone crushers, making up the other key components of the two production units, are proving to be the perfect choice for the Showa Corporation due to their high flexibility. As fully mobile secondary crushing units they are providing a rapid return on investment through their high productivity and low operational costs.

Like the jaw unit fitted to the UJ440i, the cone on both these crushers is able to handle any type of hard rock material in virtually any climatic conditions, due to its high quality construction. This is providing the Showa Corporation with trouble-free and optimal production, which is ensured by on-board high level intelligence that enables minimal set-up time through the unit?s sequential start with memorised application data. This precision crusher is further equipped with automatic setting regulation, Sandvik ASRi, and in combination with the
unique CLP crushing chamber provides excellent versatility.

One of the keys to Showa?s high productivity and efficiency has been the cone unit?s automatic setting system, ASRi, which further optimises cone crusher efficiency and automatically adapts the crusher to variations in feed conditions. By continuously measuring and compensating for crusher liner wear, ASRi allows for optimal utilisation of crusher liners and schedule liner replacements to coincide with planned maintenance stops. The ASRi also assists in keeping the crusher choke fed to maximise rock on rock crushing, which helps ensure the highest quality end product.

The Sandvik U-440 tracked crushers are currently used in two crushing trains to produce aggregate for concrete production. The first production unit concentrates on producing a 20-5mm limestone product, while the second produces a 20-5mm and 5-0mm product from a hard sandstone and andesite.

Both crushing trains are reportedly operating at high throughput and producing superb product shape. In addition to this, smaller members of the Sandvik mobile crushing and screening range, in the form of the QJ340 jaw crusher, QA140 screener and QE330 scalper, are used for special size production at various points of the sites, while the QJ240 jaw crusher is utilised to crush concrete for recycling and reuse. These latter elements further provide the Showa Corporation with enhanced operational flexibility whenever and wherever it is needed.

Because aftermarket care is key to Sandvik?s operational ethos, and to ensure the Showa Corporation would get the very best from its investment, four people were invited from the Showa Corporation to visit Europe as guests of Delbrant. They undertook service training in England, then proceeded to the Svedala factory in Sweden to learn more about the Sandvik heavy range of equipment and see heavy units operating in the field. To capitalise on the successful trip to Europe, Delbrant recently ran a further course in Japan.

This has undoubtedly paid off as Yamanoi recently placed a third order with Sandvik that not only comprises two additional QA440 screens and a US440i crusher but also two members of the ?super-heavy? range of mobiles ? the UJ540 jaw and UH640 cone.

The order from the Showa Corporation is the first step in introducing the Sandvik U-range of larger, heavy duty mobile crushing and screening equipment to Japan. It seeks to build on the excellent work already undertaken expanding the market for the Q-range of crushing and screening equipment.

All units in the Sandvik U and Q ranges of mobile crushers and screens provide customer-focused solutions for large and small operations in the construction and aggregates industries. Although perfectly capable of operating independently, they are also able to work in conjunction with each other, thereby supplying the Showa Corporation with two fully functional screening and crushing trains.
