Major crushing and screening equipment manufacturers unveiled many new machines at the Hillhead 2014 event, making use of the quarry setting near Buxton, County Derbyshire, England, for demonstrations and static displays of the latest technology. Patrick Smith reports.
“This is perfectly suited to the mobile jaw crusher MOBICAT MC 110 EVO, which made its world première at
“Like the other Kleemann crushers in the EVO range, the MCO 9 was developed especially for the needs of customers in the contractor market. Weighing approximately 30tonnes, it is easy to transport and ready for operation quickly and simply with just a few movements.”
Similar to the other Kleemann EVO models, the drive concept with crusher direct drive and electric drives of the conveyor belts also promises extremely efficient operation. The Kleemann mobile jaw crusher MC 100 R EVO is also new and has a crusher inlet size of 950 x 550mm. Weighing approximately 30tonnes it has a feed capacity of up to 200tonnes/hour and like the MC 110 R (on whose design it is heavily based) is available with options such as electromagnet or permanent magnet, extended side discharge or crusher discharge conveyors, continuous feed system (CFS) for permanent crusher loading or crusher deblocking system.
Among Terex Finlay’s machines were the J-1175E (diesel/electric) jaw crusher prototype which was running in line with a C-1540E cone crusher and 694+E inclined screen.
“We are offering a jaw, cone and screen in one complete plant which can either utilise mains electricity or has an onboard generator to provide the electric power,” says Nigel Irvine, Terex Finlay’s sales and marketing director.
“No need to purchase diesel, no need for hydraulic services or so on. Generally, electricity is a lot cheaper than fossil fuel and the maintenance costs are a lot less with electric motors.”
Another first comes from Maximus Crushing & Screening with its new design MXJ-1 mobile jaw crusher and MXC-2 cone crusher, which was also getting its world première.
The MXJ-1 primary jaw crusher has a hydraulically driven 1,150mm × 750mm jaw box and is equipped with a 10m³ capacity feed hopper, a grizzly pre-screening grid and a large 1,200mm main conveyor belt.
With a transport weight of 57tons (51.7tonnes), the MXJ-1 is powered by a
The medium to large tracked mobile crusher is equipped with a 1,200mm MSP300 high capacity cone, and is said to be ideally suited to secondary crushing applications such as taking feed from the MXJ-1 primary jaw crusher.
Sandvik Construction says its CI531 and CI532 Prisec 3 crushers provide customers with “a low capital cost solution, optimum performance and good cubical shape, while ensuring the lowest operating cost per tonne for a wide range of materials and applications.”
As with the rest of the Prisec range the HSI crushers can be configured into either a primary or secondary crusher. Additionally single-stage crushing is also a possibility with the ability to recirculate material to the primary versions of the crushers.

“The lively screening action lends itself equally as well to fine screening applications with materials such as crusher run and topsoil,” says Powerscreen.
The Powertrak 750 screen features a
The J960 ECO jaw crusher is the first mobile crusher product from
“I guess people have been wondering when we were going to get into crushing as it is a natural step after screening but we did not take this decision lightly. Crushing is not for the faint-hearted and we have spent considerable time on the J960 ECO project to get it right. A lot of time was spent understanding the features that would really make a difference to potential customers and we have designed this machine with standard items that others would consider options,” says Martin Quinn, technical director.
The J960 ECO offers a 900 x 600mm jaw opening, a dirt belt, magnet and dual power as standard. There is also an auxiliary power socket to run a separate stockpiler or to run a small generator.
Austrian manufacturer of mobile crushing and screening machines dsb Innocrush is offering its Innocrush 30 with the new Innodrive drive concept and the Innocrush 35 with built-on screenbox Innoscreen2.
The Innocrush 30 is a crusher which is directly powered without a clutch, having no clutch lining and no visco-clutch, meaning the Innodrive replaces those wear and maintenance-intensive components
The Innocrush 35 with Innoscreen 2 is powered directly from the crusher without any additional power unit, and according to the company it produces less oversized grain. With the new screenbox the oversized grain goes back into circulation and only pre-defined grain is therefore supplied. “This screenbox option is now available and no additional screening machine is required. This is a key benefit for many customers,” says dsb innocrush.
Baioni’s big plant for a big job
Italian company
Bismayah New City is owned by Hanwha Corporation. It covers 1,830 hectares and plans to accommodate around 600,000 occupants in 100,000 residential units.
To help achieve the production of aggregates for construction, affiliate civil engineering company, S & P World Networks, Korea, turned to Baioni, having previously used the company’s stationary crushing and screening equipment.
The client’s main material application is crushing alluvional abrasive material for use as aggregate for concrete production for the Bismayah project. The plant operates at 400tonnes/hour and consists of two different crushing stages.
The first stage crushes 5-200mm using two secondary impact crushers, MIS 140 and MIS 100. Material is conveyed to two screens for stockpile (0-40mm), while +40mm oversize product is further crushed using a BV 6500 vertical shaft impactor for the production of sand (0-5mm). The second stage uses a GTB 2000 bars mill to produce sand.
The fully automated crushing and screening plant includes two parallel V18.50/3 deck screens removing the 0-5mm (stockpile) while the +5mm oversize is conveyed into bag storage and then sent to crushing.
There is no primary crushing as the material received is already +200mm. At this stage the client has two parallel operational lines: production of the 0-40mm or production of the +400mm oversize product which, passing through different stages of crushing, screening, cycloning, achieves a good quality sand.
In primary production mode the plant produces a 0-4mm sand (50% of the production is sand), while in secondary production mode the +40mm oversize is processed through the combination between impact crushers, bars mill and vertical shaft impactor which provides high quality 8-13mm and 5-8mm aggregates.
