H3 MOBILE ROLLER SCREEN SYSTEM

MOS is an independent Italian company founded with the aim of developing a new generation of

mining machines. We have a long tradition as designers and manufacturers of mobile gantry cranes

and material handling systems.

After 40 years in the heavy transportation market and hundreds of machines delivered, we are still

able to grant innovative solutions and create efficient and reliable machines that are custom made.

Most of our employees are engineers and we focus our work on the material handling in opencast

mines.

MOS activity is based on a new innovative patent that assures a more efficient hauling system and

higher production screening process.

MOS H3 SERIES: 3000 ton/hour

When it comes to sizing and loading the ore material onto the extraction point of the

open pit mines, the MOS H3 Mobile Roller Screen System is particularly impressive

thanks to its exceptional performance.

Equipped with an efficient roller screen, the MOS H3 series ensures mobility (3 km/h),

high productivity (3000 ton/h) and efficiency in a rugged machine even in difficult

working conditions.

Designed and patented by MOS, this screening and loading technology is the ideal

choice for cutting mining processing costs and offers a flexible range of applications

in the open pit mines. The intuitive nature of the H3 series makes it easy to use while

also ensuring quick and trouble free positioning at the extraction point.

SIZING AND LOADING THE ORE MATERIALDIRECTLY IN THE MINING EXTRACTION LOCATION Extraction loading ore material on MOS H3 Screening onsite loading automatically on dump truck

A NEW STANDARDWith its unique features, the innovative MOS H3 series overcomes the disadvantages of the conventional mining material hauling and processing systems. Bringing the roller screen to the extraction location, waste and oversized stones will not loaded on trucks anymore. MOS H3 series is able to screen 3000 tons of ore material per hour and load it on the trucks. We set up a new standard in the market but other benefits are:

HigH production rate, sizing tHe ore material at tHe extraction location and loading automatically on trucks

total mobility on every surface and up to 8% slope to stay close to tHe extraction equipment

HigH efficiency to load on trucks only neat material, removing stones and impurities

cutting mining processing costs, reducing tHe number of necessary trucks, tHeir maintenance and most of

tHe standard equipment used nowadays

Compared to what currently exists in the market of mining in-pit screening equipment, MOS H3 series has a higher production rate, reaching 3000 metric ton per hour and combining a high capacity mobile screen to a wheel loader/shovel, but still maintaining the mobility of a standard dump truck. The machine also isolates the hard unwanted impurities like oversized rocks and loads the dump truck with only valuable fine mineral ore.The use of rolling shafts with constant gap between discs and the use of scraper tools beneath each roller to remove caked material ensure a high rate and quick scalping operation. The productivity is related to the width of the internal roller shafts (see product details) and the capacity of the used loading machines available on the extraction site.

HIGH LOADING CAPACITY

MINE OF SOLUTIONS

09

Being a mobile gantry, the MOS H3 series can travel within the mine pit and from site to site with extraordinary agility and easy maneuverability. The equipment is designed to follow the mining loading activity front and travelling on the hauling roads. It can also travel on asphalt, concrete or uneven and inclined roads up to 8% maximum slope.The MOS H3 series can steer at 90°, carousel, front or rear side in order to stay as close as possible to the loading equipment or to the loading platform area, minimizing the movements of the extraction equipment.

EXTRAORDINARY MOBILITY

The MOS H3 series screens the ore material onsite, ensuring the load of only pure material on the trucks. Where waste and oversized stones are up to 40% of the extracted material (like phosphate ore), the MOS H3 series can increase significantly the efficiency and the productivity of the whole mine. Instead of transporting waste or unprocessed ore to the screening site, it is now possible to haul more uniform and clean material, increasing the daily production rate using the same fleet of dump trucks. Or it is possible to reduce the number of mobilized dump truck to fit the daily production rate so all the fleet CAPEX and OPEX ex-penses (equipment price, drivers, fuel, tires, grease, amortization, insurance, etc.) will be significantly reduced.

HAULING ONLY PURE MATERIAL

10

With a MOS H3 series working in-pit, the customer will not need to install and operate other equipment at the feeding hopper installation. Rock breaker booms, rollers screen and rock crusher are no longer necessary.

CUTTING MORE PROCESSING COSTS

for existing conventional feeding hopper: the installed rock breaker boom, roller screen and rock crusher can be switched off. The dumped material is sent directly from the apron feeder to the installed vibrating screen. All the OPEX expenses for these machines (electrical energy, ope-rators, maintenance and so on) will be economized. It is even possible to sell these machines as second hand equipment for other mining activities. Since the oversized waste material is already removed in-pit, the OPEX for the waste disposal system will be cut. Moreover the feeding hopper will produce less noise and less vibrations, extending its operating life.

The MOS H3 series can be manufactured as per the customer needs. It also can be designed to fit within the customer’s existing loading/hauling equipment. With different gaps between roller shafts configurations, several mining material can be proces-sed granting high productivity. MOS H3 series can be used either for scaling out the fines from the loaded material (by placing the dump truck under the roller screen) or for providing feed of the oversized material (by placing the dump truck on the dumping chute). It can be used to accomplish loading and scalping for industries such as phosphates, bauxite, coal, granite, salt, gypsum, lime-stone, coke, quartz, salt, aggregates and other mineral processing applications.

VERSATILITY & CUSTOMIZABLE FEATURES

for installation of a new feeding hopper: with the MOS H3 series working in-pit, the related CAPEX expenses will be optimized and significantly reduced. Rock breaker booms, rollers screen and rock crusher are no longer necessary. Also the reduction of the waste size material results in less disposal equipment.

11

Manufacturing and maintaining all mining equipment has a relevant carbon footprint. Improving the pro-ductivity of the hauling process leads to less dump trucks roaming the mine and a reduced annual fuel consumption. To reduce our carbon footprint, we design each generation of our products to be as energy efficient as possible. When products can be used longer, fewer resources need to be extracted from the earth to make new ones.

mos H3 series is designed to support rollers screen that size the ore material and dump the coarse fraction to the ground.

Operating Rollers The rollers screen is composed by two set of rotating rollers break the ore ma-terial and move it along. Fine grains smaller than the effective separating size drop down between the rollers and fall into the dump truck. Coarse grains big-ger than the separating size are pushed forward and dumped through the chute.

Upper Trolley Framethe upper trolley, with its frame, supports all the rollers and the bucket and it is equipped with translation wheel bogies. two hydraulic cylinders move the trolley for a better transversal distribution of sized ore material on truck body.this translation can be done in automatic or manually using the controls in the operator’s cabin; the translation movement is done during bucket rotation for minimizing the cycle time. all the process is controlled by cameras and visualized in the monitors inside the operator’s cab.

STRUCTUREAND TIRE GROUPS The H3 series has the shape of a mobile gantry for receiving underneath the dump trucks and it is provided with steering tires for moving in the mine at 2.8 km/h, following the loader and distributing the ore mineral on the dump trucks.The frame of MOS H3 series is designed with box section for a better torsion and bending strength. Mild steel used throughout provides flexibility, durability and resistance to impact loads, even in cold climates. The frame and its parts are bolted and can be stored and shipped inside containers. The frame sits on four twin tire groups provided each one with a special shock absorber.
