Stallion for Investment says it has improved aggregate quality, operational productivity and efficiency at a customer’s site in Egypt. Patrick Smith reports The 460 Sandvik Construction authorised distributor for crushing and screening products in the country has done this through the use of CH 430 and CH 440 cones in conjunction with Sandvik’s Flexifeed mantle. This is fitted to the customer’s cone crushers to more effectively process abrasive aggregate, playing a key role increasing capacity, as well as reducing the cost per tonne of production.
Stallion for Investment is part of the Rodan Group of companies, which was founded in 1976 by Ashraf L.Youssef, specifically to meet the growing demands of the road construction and quarry industry in Egypt for high-end equipment and spare parts, all backed by aftermarket care. cost of stone crusher
Today the Rodan Group is one of Egypt’s leading construction and quarry equipment distributors, with the group specifically aiming to offer its customers access to equipment from some of the leading equipment manufacturers.
It now represents a wide-ranging portfolio of manufacturers through its locally-developed and rapidly expanding network of affiliated companies. These are strategically positioned to support the specific requirements of customers, and this was seen when a longstanding quarry customer, who also acts as a distributor for a Chinese crusher manufacturer, sought help and advice to maximise productivity while improving end product quality.
The customer produces aggregates for the burgeoning Egyptian construction industry, and is a user of both Sandvik CH 430 and CH 440 Stallion for Investment customer’s quarry has a very hard 99% Silica rock, which due to its abrasive nature proved to be particularly hard wearing on the liners of the Sandvik cones. Although well within the parameters established by the customer, providing production of over 150tonnes/hour, the liners were only lasting an average of 12 days of continuous 15-hours daily operation. A new solution was required: the Flexifeed mantle from Sandvik Construction.
“On the CH440 the liners lasted a great deal longer, even though the Flexifeed is a heavier mantle with more material in it,” says Tarek Youssef of Stallion for Investment.
“Based on our advice the customer used to operate its jaw and a cone at any given time so we were able to switch between the CH430 and the CH440 whenever the liners wore down, giving us time to change the liners of one cone while the other was operating, thereby providing almost continuous production.”
Sandvik says its Flexifeed mantle optimises the crushing process, producing a finer product and greater reduction through the crusher. This is accomplished as the mantle is able to achieve a more efficient crushing operation due to the latest chamber design. Using Flexifeed, the crusher can accept over-sized material in part of the chamber, while simultaneously reducing the chamber profile in the opposing part of the chamber, thus permitting operation at a tighter setting. This results in a finer product being produced on a first pass basis, but also a superior shape which is essential when the equipment is set up to produce single-size products.
“As our customer is keen to minimise its carbon footprint, improved crushing efficiency means not only better production, but also lower emissions,” says Tarek Youssef.
Indeed, in the UK, County Kent, England-based KKB Group is also ramping up productivity with the introduction of a new model 668 Terex Finlay J-1170. Supplied by Finlay Plant South East last year, the J-1170 is supporting KKB Group’s commitment to maximise the value of waste material.
Specialists in the recovery and recycling of construction waste, the group is using the new machine to crush concrete, making Type 1 MOT graded material, which is reused as infill, piling mats and sub-base.
“The Terex Finlay J-1170 is delivering excellent production rates and is working well on site,” says Colin Basi of KKB Group.
The Terex Finlay J-1170 tracked primary jaw crusher is said to offer a range of features for the recycling and quarrying industries.
At the heart of the machine is a hydrostatically driven 3652 Terex jaw chamber, which provides high capacity with large reduction ratios. The jaw chamber configuration can be set up specifically for either processing construction demolition debris or quarrying applications.
It also features a heavy-duty variable speed VGF and integrated pre-screen while options include a variable speed pan feeder along with an independent pre-screen system.
The jaw chamber is also available with optional hydraulic release, which is of value when crushing construction and demolition debris, due to an automatic overload protection system to prevent damage by uncrushable items in the feed material. Another development has come with the new Terex CRH1316 portable HSI plant. Electrically powered, Terex Minerals Processing Systems (Terex MPS) has added the Terex CRH1316 horizontal shaft impact crushing plant to its CR Series portable plant. It features a large under-crusher vibrating pan feeder to accept the high velocity crusher discharge material and convey it to the straight-line product conveyor, a design said to eliminate impact damage to the conveyor belt and maintain maximum belt tension to prevent slippage, while providing a very large discharge opening to prevent blockages.
To complement the CRH1316, Terex MPS has also released the new CRC380X and CRC450X cone plants and the CRS6203V screen plant.
“This new plant addresses the issue of handling the high velocity discharge from impact style crushers. As with all of our new CR Series portable plants, it was developed with input from numerous customers. Our plants include many design features that simplify maintenance and allow plants to be mated and configured to meet various customer needs,” says Ed Sauser, product manager at Terex MPS, which has also unveiled its new MC1300 cone module, increasing the application and production capabilities of its existing modular product range.
It can be matched with other units in the modular product line to create a system capable of processing up to 270tonnes/hour.
In screening, 613 Anaconda Equipment launched the FSL100 tracked scalping screen which produces two end products and can be a pre- or post-crushing screener.
The company says the FSL100 has been added to its range to address requirements from customers around the globe who do not require conventional three-way segregation of product.
“The FSL100, like many of the Anaconda screens, will ship worldwide in a standard 40 feet container,” says Anaconda.
Powered by a JCB444 Dieselmax engine or a Deutz TD2011FL04i engine, the two-deck vibrating grid can be fitted with grizzly bars, fingers, punch plate or mesh, and the hopper is protected by a heavy-duty plate to prevent damage when clearing the oversize product from the machine.
The feeder belt and the discharge belt both offer variable speed control and the machine can be operated by wired or radio remote control.
“Designing new products in tandem with our dealer network has been a key factor in our success to date,” says Alistair Forsyth, managing director. “The FSL100 has once again evolved from these discussions.” Major Wire Industries says its new crown bar adaptors for modular decks allow producers to convert their flat screen decks to a crowned deck on both pin and grooved-type screen decks.
“This innovative technology will allow producers to choose the best screen media for the job without being limited by the screen deck,” says the company.
Major Wire says it developed its line of crown bar adaptors to fill an expressed need for producers with flat screen decks that were limited to only using modular type screen media but wanted to use 3815 Major Wire’s Flex-Mat 3 tensioned high-performance screen media.
Flex-Mat 3 panels employ independently vibrating wires that are said to increase product throughput by up to 40% over polyurethane and rubber panels by increasing open area and eliminating blinding, pegging and clogging..
What is said to be the world’s first educational, mobile and fully-automated 448 Metso plant worldwide was inaugurated late last year in Taivalkoski, north-east Finland.
Three Lokotracks, Metso DNA automation system including operator training simulator and Bruno process simulation are among the main practical tools for training skilled, future miners and crushing contractors in Finland. As a result of the mining boom, Finland alone will need to create 5,000 new mining jobs between now and 2020, and one-third of these jobs will be in crushing. To achieve this, the training of miners has to be doubled quickly. Many colleges have started offering courses for miners to fill the existing GAP.
Oulu Vocational College (OSAO) is one of the new schools offering mining courses with a three-year programme for students to become professional miners or crushing contractors.
The programme includes classroom work in crushing theory and parameters in addition to on-site work with a Lokotrack LT106 jaw plant; LT200HP cone plant; ST3.5 mobile screen and the Metso DNA automation system. Along with the Metso units, an excavator and front-end loader are used. In the Metso plant automation application, operation and camera screens are installed in the excavator feeding the Lokotrack and in a separate on-site cabin. The touch screen enables the excavator operator to control and monitor the process without visiting the machines, which increases both productivity and safety.
In addition to the real machinery, the college owns state-of-the-art excavator and front-end-loader simulators that even simulate the operator’s seat movements. In one classroom, Bruno process simulations are rehearsed. In the near future, OSAO will still assemble a small-scale rock laboratory to test rock and ore parameters.
“We intend to organise further crushing and screening training for adults. Our intention is to stay at the top of crushing knowledge,” says Kalevi Hirvonen, OSAO project manager.
mobile vsi crusher “We intend to continue our close cooperation with the college, serving widely the domestic and international training needs of crushing and screening equipment customers and partners,” says Kari Kokkonen, vice president, technical support, Metso crushing and screening equipment.
