Discription of bucket conveyor

A bucket elevator can elevate a variety of bulk materials from light to heavy and from fine to large lumps. A centrifugal discharge elevator may be vertical or inclined. Vertical elevators depend entirely on the action of centrifugal force to get the material into the discharge chute and must be run at speeds relatively high. Inclined elevators with buckets spaced apart or set close together may have the discharge chute set partly under the head pulley. Since they don't depend entirely on the centrifugal force to put the material into the chute, the speed may be relatively lower. Nearly all centrifugal discharge elevators have spaced buckets with rounded bottoms. They pick up their load from a boot, a pit, or a pile of material at the foot pulley. The buckets can be also triangular in cross section and set close to on the belt with little or no clearance between them. This is a continuous bucket elevator. Its main use is to carry difficult materials at slow speed.

Early bucket elevators used a flat chain with small, steel buckets attached every few inches. While some elevators still are manufactured with a chain and steel buckets, most current bucket elevator construction uses a rubber belt with plastic buckets. Pulleys several feet in diameter are used at the top and bottom. The top pulley is driven by an electric motor.The bucket elevator is the enabling technology that permitted the construction of grain elevators. A diverter at the top of the elevator allows the grain to be sent to the chosen bin. A similar device with flat steps is occasionally used as an elevator for humans, e.g., for employees in parking garages. (This sort of elevator is generally considered too dangerous to allow use by the public.)

Discription of storage silo for grain

A silo is a structure for storing bulk materials. Silos are used in agriculture to store grain (see grain elevators) or fermented feed known as silage. Silos are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust.

Hopper Bottom Silos are generally built on fabricated steel structures with conical bottom made of steel plates and the corrugated sheets preformed are assembled with bolts and nuts on circular purlins and vertical stiffeners with water proof washers , cylindrically above the conical hopper with a slopped roof in the top. Ladders to clim b and get into the silos, handrails, manholes etc are provided. The grains will be discharged by gravity to the bucket elevator/belt conveyor for onward conveying. These silos can also be built on the top of concrete conical hopperhopper bottom silos. Normally these silos are recommended for storage upto 500 tones of grains like paddy having density of less than 550kg/m3. with beams and columns built in situ. Aeration, ventilation, temperature monitoring system as required are all provided to the built

Characteristics

Hopper Bottom Silos are multipurpose and are suitable for grain processing plants, animal feed plants, grain milling plants, and poultry houses.

Hopper Bottom Silos are manufactured in capacities from 20 Tons to 1000 Tons.

Zincalume steels sheets are used in the manufacturing of the silos, which are able to withstand strength 350 Mpa.

Standard angle for bottom hopper of a silo is 45 degrees. However, the bottom hoppers of angle 50, 55, 60 degrees may also be manufactured on request

Description of Ribbon Blenders

The koyka group ribbon blender are based on a proven agitator construction that provides a triple mixing action thus ensuring fast efficient blending. The dimensions and configuration of the ribbons in ribbon blender are carefully balanced to provide a movement of material within the container that avoids dead spots and gives rapid product discharge. The design of the Jas ribbon blender can incorporate features required for a customer's product or process such as: wear resistance, corrosive resistance, vacuum filling and discharge arrangements, special shaft seals, heating/cooling jackets. Ribbon blender are available in sizes 100-8000 liters in Stainless Steel 304, Stainless Steel 316 and Mild Steel Construction.

About ribbon blender design

Ribbon blender are widely used for homogeneous mixing of dry granules and powders. The blender comprises a "U" tank, shaft with two sets of spiral ribbons, one inside the other. Inner and outer ribbons are perfectly arranged, that during rotation, the material reaches each corner of the trough and imparts radial and linear motion to the whole of the material to be mixed. Our range of ribbon blender are based on a proven agitator construction that provides a triple mixing action ensuring fast, efficient blending. As the agitator rotates in ribbon blender, the material is tumbled and carried radically around the inside of the blender. The pitch of the outer ribbon moves the material towards the discharge opening. The inner ribbon which has an opposing pitch moves the material away from the discharge opening.

Another feature of this mill is that effective and continuous crushing leads to increased production and faster return on investments.

Operating principle of pulses and grains grinder

koyka group's pulses and grains grinders are durable utility grinders capable of grinding most pulses and grains. The Techno wings multipurpose pulses and grains grinder comprises of a heavy duty aluminum body (alternatively stainless steel construction can be provided in multipurpose pulses and grains grinder wherever necessary). Multipurpose pulses and grains grinder operate on the principle that most materials will grind or crush upon impact with the hammers. The material is feed into a multipurpose pulses and grains grinder from the top back through gravity into the grinding chamber. The grinding chamber of multipurpose pulses and grains grinder is lined with serrated wear plates, which protects the body from wear and tear. Design provides for admitting extra air during grinding to facilitate cool operation. Soft to medium hard materials are quickly pulverized to fine powder. Improved mixing and dispersion are added advantages of such mills. Quite popularly, it is also called high speed close tolerance grains mill. Uniformly fed material undergoes a complex grinding force through attrition between liner plate and hammer tip, impact of high speed hammers and collision between particles. Bottom sieve controls the particle size.

Discription of screw conveyor

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water.

They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.

A flexible screw conveyor works by using the internal friction within a powder or bulk solid to transfer the forward motion of the powder in contact with the spiral to the whole tube contents. With an angled system, a dynamic equilibrium is set up with the spiral action moving some particles upwards.

Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.

The rotating part of the conveyor is sometimes called simply an auger.

Discription of grain cooling system

The cooling system works for silos and warehouses.

For silos, the refrigerator is connected instead of the aeration fan. Installation is simple requiring minimal modifications. In fact, the system can be easily moved around and connected to other silos as required.

For warehouses, a ducting system is included at the base.
