  • TYRES & SUPPORT ROLLERS

    TYRES & SUPPORT ROLLERS

    Request for Price

    Tyres, sometimes called riding rings, usually consist of a single annular steel casting, machined to a smooth cylindrical surface, which attach loosely to the kiln shell through wedge arrangements. These require some ingenuity of design, since the tyre must fit the shell snugly, but also allow thermal movement. The tyre rides on pairs of steel support rollers, also machined to a smooth cylindrical surface and set about half a kiln-diameter apart. The rollers must support the kiln and allow rotation that is as nearly frictionless as possible. Depend on size and capacity an additional tyre can be provided with a set of support rollers. Kilns usually rotate at 0.5 to 2 rpm. The bearings of the support rollers must be capable of withstanding the large static and live loads involved, and must be carefully protected from the heat of the kiln and the ingress of dust. In addition to support rollers, there are usually upper and lower "retaining (or thrust) rollers" bearing against the side of tyres, that prevent the kiln from slipping off the support rollers.

  • Spray Dryer

    Spray Dryer

    Request for Price

    Spray drying is the transformation of feed from a fluid state into a dried form by spraying the feed into a hot drying medium. The feed is pumped from the product feed tank to the atomizing device, located in the air disperser at the top of the drying chamber. The drying air is drawn from the atmosphere via a filter by a supply fan and is passed through the air heater to the air disperser. The atomized droplets meet the hot air and the evaporation takes place, while cooling of the air happen simultaneously. In Spray Drier, after the spray is dried in the drying chamber, the majority of the dried product falls to the bottom of the chamber and enters to a pneumatic conveying and cooling system.The fines, which are the particles with a small diameter, will remain in the air, and it is therefore necessary to pass the air through cyclones to separate the fines. The fines leave the cyclone at the bottom via a locking device and enter the pneumatic system, too. The air passes from the cyclone to the atmosphere via the exhaust fan. The two fractions of powder are collected in the pneumatic system for conveying and cooling and are passed through a cyclone for separation, after which they are bagged off. The instrumentation comprises indication of the temperature of the inlet and outlet air, as well as automatic control of the inlet temperature by altering the steam pressure, amount of oil or gas to the air heater, and automatic control of the outlet temperature by altering the amount of feed pumped to the atomizing device.  There are two basic types of atomization : Nozzle atomizer Disc atomizer Spray Drier Configuration : Co-Current Flow Counter Current Flow Advantages Of Using A Spray Dryer For Drying Application : Control of particle size. Spray dryers can typically produce between 30 to 500 micron average particle sizes, in a bell shaped distribution. The shape of most spray dried particles is spherical, which provides for fluid-like flow properties. Spray drying produces the most homogeneous product. Many heat sensitive products can be spray dried easily at relatively high inlet temperatures. Permits drying without thermal degradation.

  • Spin Flash Dryer

    Spin Flash Dryer

    Request for Price

    Spin Flash Drier is used for effective and efficient method of removal of surface or on bound moisture from a feed product. Spin Flash Driers are designed for continuous drying of cohesive and non-cohesive pastes, filter cakes and high viscosity liquids. The wet cake appears granular and gets fluidized. Instantaneous exchange of heat and mass take place. The dried materials are taken in the collector as powder products. PRINCIPLE OF SPIN FLASH DRYING The Spin Flash Drying is more often in the line of an agitated fluidized bed system. The drying agitator works as rotor to break the lumps and the hot air enters at reasonably high velocities to give dynamic action to dry and disintegrate the product.Fresh air is sucked through hot air generator, which can be direct or indirect the nature. The entry to the drying chamber is tangential to give whirling air suction across the dryer. The hot air generator can be liquid, solid or gaseous fuel fired. The feed screw pushes the material to the drying chamber. The drying chamber has a rotor driven from the bottom. The rotor has specially designed scrapper blades and disintegrator for breaking the lumpy mass into smaller fragments. The lumps, which are broken by the rotor, start drying and simultaneously disintegrating in the stream of hot air. The airborne fine powder particles get carried to the top of the drying chamber and a classifier classifies them to the required size. The particles with larger diameter go back to the chamber, while the fine travel through with the air for final collection through Reverse Pulse Bag Filters, wherein almost 100% powder recovery is achieved. ADVANTAGES OF SPIN FLASH DRYING SYSTEM Energy consumption is much less than spray dryers, fluidized bed dryers, flash dryers, rotary dries, tray driers etc. Space requirement for installing this dryer is much less than spray dryer, pneumatic dryer, fluidized bed dryer and rotary dryer etc. It is a completely automatic plant with temperature controller etc. Dry product discharge section of the dryer can be installed in your product packing section, hence cost of transport of dry product to the finished product section can be eliminated. Pulverizing after drying will not be required. The unit will dry, classify and convey all in a single operation. Wet cake can be directly fed from filter/centrifuge to lump breaker bin, which feeds the cake in to the dryer and hence all intermediate handling of material can be eliminated. The entire system is closed and hence any chance of contamination is eliminated. Since it is a closed system, wastage and dusting etc. are totally eliminated resulting in clean environment, zero wastage and total recovery of product and pollution free atmosphere. It is possible to vary the bulk densities also by minor changes in the classifier situated near the top of the dryer. COMPONENTS OF SPIN FLASH DRYER (A) HOT AIR GENERATION SYSTEM This will consist of a hot air generator - direct/indirect/finned tube heat exchanger type.

  • Single Mechanical Seal

    Single Mechanical Seal

    Request for Price

    A single mechanical seal consists of two very flat surfaces that are pressed together by a spring and slide against each other. Between these two surfaces is a fluid film generated by the product. This fluid film prevents the mechanical seal from touching the stationary ring. An absence of this fluid film (dry running of the pump) results in frictional heat and ultimate destruction of the mechanical seal. Mechanical seals tend to leak a vapor from the high pressure side to the low pressure side. This fluid lubricates the seal faces and absorbs the heat generated from the associated friction, which crosses the seal faces as a liquid and vaporizes into the atmosphere. So, it's common practice to use a single mechanical seal if the product poses little to no risk to the environment.

  • Refractory Lining

    Refractory Lining

    Request for Price

    The purpose of the refractory lining is to insulate the steel shell from the high temperatures inside the kiln and to protect it from the corrosive properties of the process material. It may consist of refractory bricks or cast refractory concrete. The refractory selected depends upon the temperature inside the kiln and the chemical nature of the material being processed. Mostly refractory is installed as solid block to fit in to different areas tightly in round formation from sliding or falling out. There are many types of bricks in different composition and have different properties such as insulation value, maximum temperature and resistance to wear. Areas where brick cannot be used liquid refractor called castables are used with anchor support. Also provided insulation material under the brick and this extra layer helps to reduce the heat transfer to the shell. A typical refractory will be capable of maintaining a temperature drop of 1000°C or more between its hot and cold faces. The shell temperature needs to be maintained below around 350°C in order to protect the steel from damage and continuous infrared scanners are used to give early warning of "hot-spots" indicative of refractory failure.
