To cleanse off adhering impurities from the surface of broken ore ranging from 0 to 25 mm, washing is generally recommended in Drum Scrubber. MBE-CMTs rugged designs, anti-abrasion coatings of alloyed steel ensure a good life. The washing can be done by ways, co-current as well as counter current. Models are available with and without trommels.

Chain conveyors can be used to transport any type of bulk material safely, gently, with all-round protection and with minimum space requirements. They can transport coal, sorted domestic waste, sewage sludge, filter dust, fly ash, wood chips, cement, clinker, limestone, biomass or alternative fuel. The hot-galvanized flanged casing consists of a tail and a head section, as well as a number of modular intermediate sections. The tail and the head section contain drag and transmission roller.

In the double roll crusher the feed is distributed by a feeder over the entire roll width. The material is drawn into the crushing gap by appropriately shaped teeth projecting from the rolls. For special applications, teeth of different heights are available at option.

The anticipated maximum feed size determines the roll diameter. The size of the desired product can be fixed by the adjustable gap width between tip and bottom of tooth.

The throughput rate is a function of roll width, gap width and peripheral speed.

Both swings systems are carried in the base frame. The crusher rolls are hollow cylinders with headwalls and bearing shafts. Webs fitted to the roll body parallel to the cylinder axis provide for additional securing of the crushing shells. The bearing journals run in self aligning roller bearings and are protected against dust by shaft sealing and labyrinth rings.

Forces generated during crushing are transmitted via the bearing housings and absorbed by the swing retaining frame direct. The gap setting can be adjusted by way of a spindle with threaded sleeve. This adjusting device is normally combined with the mechanical overload protection.

Each crusher roll is driven by a fly-wheel type pulley which serves at the same time as a V-belt pulley. The drive is installed vertically underneath the pulley. This arrangement eliminates re-tensioning of the V-belts and re-locating of the feeder with advancing wear of the crushing shells.

The practical application of roller crushers for a multitude of duties has resulted in the development of a standard machine which, on request, can be modified to a special type of equipment for given comminution tasks.

Special Characteristic features:

• Low machine weight due to the double swing system.
• No transmission into the foundation of the forces generated during the reduction process.
• Counter balancing by retraction of the crusher rolls.
• No re-location of the feeder required, not even in case of pronounced wear.
• Easy replacement of the crushing shells and simple removal of the crusher rolls.
• Effective protection of the bearings against dust and other contaminations.
• Vertical arrangements of the drive which eliminates the necessity of V-belt tensioning upon changes in the gap width or in case of overload.

MBE Coal & Mineral Technology USK (Circular vibrating screen), USL(Linear vibrating screen) and VSL (High Frequency Screen) with throughputs from 15 to 800 TPHare the result of our constant research and development, based on many years of experience in the construction and manufacture of screening machines, which allows our valued clients to select at any time the best machine for operating requirements. MBE has in its product range, three types of screens to suit various needs of the client, namely, Linear Motion Screen (USL), Circular Motion Screen(USK) and High Frequency Screen (VSL). USL Vibrating Screen: This type of screens with linear vibration motion are used for dry or wet screening of coarse, medium or fine grain sizes. Since the vibration movement is linear, the screen may be positioned horizontally or with a slight inclination. USK Vibrating Screen: This type of screens with circular vibration motion are particularly suitable for dry and wet grading of coarse and medium grain sizes in the range from about 80 to 0.5 mm. VSL Vibrating Screen: This type of Vibrating Screen is used for dewatering and sizing of fines (-0.5 mm) using vibrating frequency of 1500 RPM. With the Vibration motors mounted on the top of the Screen,

It is a mechanical classifier which separates on the basis of settling rates of the particles (coarse & fine) in the fluid medium (water). MBE CMT Spiral Classifiers are manufactured as Simplex Submerged Type based on the proven principle of AKINS spiral classifier. Due to the larger and quieter pool, this type of Classifier is applied for finer separations (65# to 325 #) and throughput range from 30 to 275 tph depending on solid concentration.

Very Slow Speed Spiral Classifier is being used for dewatering purposes in various Iron Ore beneficiation plants.

MBE has in its product range, two types of environmental centrifuges, 2 Phase centrifuges & 3 Phase centrifuges.

Solid Bowl Centrifuges Co-Current design (2 Phase): The feed material is into solid bowl centrifuge with the aid of a pump. Progressive cavity pumps are commonly used for this duty, as they ensure a controlled uniform delivery of the feed. The feed rate may be ascertained with the aid of s flow meter in order to determine the throughput rate per hour or per day. The feed material is first pumped through a stationary feed pipe (1) into the feed compartment (2) which is located in the hub of the material screw conveyor (5) and within the field of centrifugal forces. The effect of these centrifugal forces causes the feed to flow through the feed compartment outlets (3) and into the bowl (4) of the solid bowl centrifuge.

The principal of co current flow starts the settling process as the feed enters at the large diameter end of the bowl. Solids and liquid are transported in the same direction. Hence, the complete bowl length is available for setting. This arrangement provides long settling distances and extended sedimentation time for the feed material to be dewatered or thickened. The settling operation proceeds uniformly, trouble free and with minimal turbulence.

The centrifugal force developed during normal operation causes the relatively heavy solid particles to settle on the bowl wall. These sedimented particles are transported inside the bowl by the screw conveyor (5) to the solids discharge point (7). Bowl and screw conveyor rotate in the same direction, but the screw conveyor speed slightly differs from that of the bowl. That differential speed is brought about by a suitable gearbox (6) by the corresponding transmission ratio of the V-belt drive, or through the utilization of s special hydraulic scroll drive system.

The separated solids are discharged through outlet openings (7) and are collected in casing (8). They are then routed through a chute to be discharged. The cent rate flows through the return channels (11) fixed to the conveyor hub in the opposite direction to that of the solids. The liquid leaves the centrifuge at the feed inlet end. This arrangement avoids interference with the sedimentation process, which normally occurs with the traditional countercurrent design.

The return channels for the cent rate discharge are sized so that the velocity of the flow substantially prevents the sedimentation of superfine solids contained in the cent rate against the interior walls of the channels. The cent rate is discharged over vertically adjustable weir plates (12) thus allowing for changes to be made to the cent rate level and consequently , altering the volume of the liquid retained inside the centrifuge. The cent rate is discharged through a chute. Visual inspection of the cent rate for the purpose of controlling the cent rate clarity is possible by taking samples at the machine outlet. Alternatively, provision can be made for automatic cent rate turbidity measurement and adjustment.

• High Separation Efficiency: Solid Bowl Centrifuge is designed for Co-Current flow incorporating, long settling distance, high pool depth, longer dry beach and small angle. Hence, no turbulence will occur with high pool depth and long dry beach, ultimately extending the sedimentation time.
• Low Power Consumption: These centrifuges are operated at low G force/low speed without turbulence and small beach angle. Hence, low power requirement about 08KWH.MH3 and low wear & tear without compromising efficient dewatering.
• Optimum Cake Dryness: Cake dryness is optimized by varying the differential speed between 2-50 rpm by simply changing the pulleys.
• Efficient Wear Protection: Conveyor flight and other wear prone parts are lined with tungsten carbide which is much more superior to standard stelite hard surfacing. The wear & tear of bowl shell is prevented by strip lining.
• Easy Maintenance: MBE CMT Solid Bowl Centrifuge construction is simple with centralized lubrication system by which all the bearings can be lubricated while the machine is in operation.

Robust design

ROMJIGspecifically developed for treating ROM coal for deshaling purposes. Earlier jigs were incapable of deshaling without crushing the ROM coal to a size less than 150 mm which incurred extra costs. But with the development and introduction of the ROMJIG this limitation was done away with and ROM coal with sizes upto400 mmcould be directly Deshaled with this machine without crushing. This method also thus helps in protecting the subsequent comminution system. This machine is a movable bed screen with excellent separation efficiencies and robust design. It is highlighted by advantages such as absence of hutch water clarification, low water and energy demands and small number of ancillary equipments. Therefore, it outrivals any other method of mechanical refuse separation.

The horizontally arranged MBE CMTI vibrating Screen Basket Centrifuge, the material to be dewatered is fed into the inlet cone through the feed pipe. While flowing through the inlet cone, the material is slowly accelerated and uniformly distributed on the circumference of the slot type Screen Basket. The rotating basket is made to perform axial vibration by a vibrator unit with unbalanced drive.

Due to the combination of Centrifugal & Vibratory components, these axial vibrations have the material transported inside the conical screen basket along the inclined basket will. This movement entails a reduced friction between the feed & basket wall.

The Centrifuge is mounted on Rubber Buffers for preventing the transmission of vibrations to the foundation. Vibration may occur as a result of fluctuating feed rates.

The horizontal design permits fitting the drive components to the outside of the machine housing. This means that all drive parts and consequently the basket inside the machine housing is easily accessible. The one piece Screen Basket and the inlet cone have been fastened to the Basket Shaft in an overhung position by means of the load bearing ring. This ensures easy assembly & dismantling. The vibrator with out of balance weight is accommodated in the bearing housing of the basket shaft. The complete drive mechanism has been suspended by the guide linkage spring. The axial vibrations are transmitted to the screen basket direct on the basket shaft and the load bearing ring without resilient element having been interposed. This results in a very simple & robust design. The vibrating mass is made up of the Screen Basket, Inlet cone, Load Bearing Ring & Basket Shaft as well as of the drive mechanism. It exceeds by further mass of material accumulating. Due to this fact and the horizontal arrangement, the centrifuge is insensitive towards the overload or fluctuating feed rates. The Screen Basket & Vibrator are each driven by a standard motor and V Belt.The MBE Basket Centrifuge is particularly suitable for continuous separation of solid/ liquid mixtures of grainy bulk materials. The standardized design of mechanical & Centrifugal components enables optimum adaption to the specific requirement. Details of this standardized design, of the dewatering process & design criterion have been given on the following pages.

Jaw crusher is mainly used for primary crushing. It is made up of frame, eccentric shaft, grooved wheel, and flywheel, moving jaw, side guard plate, and toggle plate, toggle backseat, adjusting screw, returning spring, fixed jaw plate and moving jaw plate. Toggle plate is of safety function. ixed jaw plate and moving jaw plate. Toggle plate is of safety function.In jaw crusher the material is being sandwiched between the two jaws. The jaw moves to the maximum position of the jaw plate, i.e., the movable the jaw plate leaves the fixed jaw plate to the furthest position. Then the material falls into the crushing chamber, the movable jaw plate moves gradually to the fixed jaw plate, thus material is squeezed into several small pieces. Due to gravity, the crushed material will fall, and those small enough will be discharged by the crusher. And the bigger sizes will fall to the bottom of jaw crusher chamber, and will be crushed again with newly fed raw materials.

It is used for handling coarse ore, especially Primary Crusher feed. MBE-CMT is ruggedly constructed, consisting of a series of high carbon/manganese steel pans, bolted to strands of heavy duty chain, which run on steel sprokets.
