Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries.
The Major Utilization Areas Of Fly Ash :
- Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC).
- Part replacement of OPC in cement concrete.
- High volume Fly Ash concrete.
- Roller Compacted Concrete used for dam & pavement construction.
- Manufacture of ash bricks and other building products.
- Construction of road embankments, structural fills, low lying area development.
- As a soil amender in agriculture and wasteland development.
Types of Fly Ash:
- According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties.
- Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product.
- Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash.
- Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics.

Grade: P0, P5,4. Notes: Tapered roller bearings with radial oriented mainly to bear radial and axial joint load. Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity. This kind of bearing is separable bearings, rolling bearings according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance adjustment required to the user during installation; Double row and four row tapered roller bearing clearance from the factory has been given based on user requirements, users do not need to adjust.Tapered roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. The surface of the projection lines of all cone bearing axis in the same point together. This design makes tapered roller bearings particularly suitable for bearing complex (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle �± ; A angle increases, the higher the axial load capacity. Angle size of the computational coefficient e to represent; E greater the contact angle the greater the bearing axial load greater applicability.Tapered roller bearings are usually separated type, that is, with roller and cage assembly of the inner components of the composition of the inner cone with tapered outer (outer) installed separately.5. Application: Tapered roller bearings are widely used in automotive, mill, mine, metallurgy, plastics and machinery.6. Packing: Single colour boxes or industrial packing, carton around 22kg, then into wooden or steel pallet.
We are manufacturer of all types of tapered roller bearing. The given part numbers 30204 (br-30204) / 320/32x (br-320/32) / 30205 / u399-u360l / etc of the tapered roller bearing are suitable for tata ace. We also accept the drawing of the customer and according to that drawing, we developed their product.
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.>
This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e. the differences in surface speeds creates a scrubbing action. Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems. Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear.
The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
The larger the half angles of these cones the larger the axial force that the bearing can sustain.
Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup. Internal clearance is established during mounting by the axial position of the cone relative to the cup.

Tapered roller bearings can be separated from the inner ring with roller cage components together and the outer ring can be installed separately. As amended by the roller and raceway contact at the contact line can reduce the stress concentration. The tapered roller bearing can withstand large radial and axial load. Tapered roller bearings can only pass one-way axial load, axial load in the opposite direction to pass on another with symmetrical installation of tapered roller bearings. The tapered roller bearings, the largest amount of single row tapered roller bearings. In the front wheels of cars in recent years, using the small size of the double row tapered roller bearings.
