  1. CONSTRUCTION SEQUENCE OF SILOS by L.SUCHITHRA
  2. SILOS Silos are deep bins in which the plane of rupture of material store meets the opposite sides of the structure before meeting the top horizontal surface of the material. It is a tall cylindrical structure. TYPES OF SILOS: Reinforced concrete silos Prestressed concrete silos Steel silo Concrete block silo Fibre Reinforced Polymer Silos
  3. CONSTRUCTION SEQUENCE OF SILOS Foundation: The foundation should necessarily be a raft construction. It should be constructed in one pair to avoid cold joint. Wall: Three methods are available v/ Conventional method v/ Jumpform method Slipform method. Roof slab: The roof slab is of concrete. However, it is not possible to do stuttering for the slab/beam system from bottom.
  4. Tunnel inside silo: Plum concrete is done in the bottom zone of the silo and the tunnel base slab, side wall and roof are constructed in the sequence by conventional method. Floor of silo: This rests on plum concrete and this floor is constructed by convential method.Concreting is done through manholes provided in the side walls.
  5. CONSTRUCTION TYPE The construction types of silos are Flat Bottom Silos Hopper Bottom Silos Smooth Wall Silos Stainless Steel Silos Corrugated Steel Silos Bolted & Welded Steel Silos Elevated Silos Tower Silos Transportable Silos Lipp Silo
  6. FLAT BOTTOM SILOS Flat bottom silo, a flat surface is required to give full support. v/ The floor design of the steel silos is decided by the material to be silos. In flat bottom silos, air slides can be bolted onto the plinths cast into the floor or bolted directly to the silo floor. v/ If you plan to store cement, fly ash or other materials that require fluidizing systems, flat bottom silos are generally the first choice. For a custom made steel silos such as columns are required below the silo floor, our material handling designers and silo designers will reach agreement through consultation to ensure the needs of both are
  7. met. Additionally, if the steel grain silos need to accept loads from mixing, condition and unloading equipments, equipment floors will be added to the steel silo plans. Flat bottom silos are one of the most common used steel silos in agricultural industry. And they are regard as the most popular and cost-effective way for long term storage, especially for grain and feed storage. All our flat bottoms are designed and constructed in accordance with D-4097 or ASTM D-3299 standards.

  9. CONSTRUCTION OF FLAT BOTTOM SILO
  10. HOPPER BOTTOM SILOS Hopper bottom silo, also named as cone bottom silo, hopper bottom storage bins, refers to silo with a cone bottom. Generally, a funnel is needed in the silo for most material storage. v/ For small silo storages, the steel hopper/cone can be fixed with the sidewalls. v/ However for industrial silos with large diameter, to reduce the risk, the hopper/cone is designed to be supported by the silo bottom floor. Hopper bottom silo contains complete drainage.
  11. The configuration of hopper silo depends on the type of material to be stored. v/ In generally, pellet products require a 450 cone bottom silo while powder or other material which is hard to flow fits 600 cone bottom silo storage. Hopper bottoms are designed in accordance D-4097 or ASTM D-3299 standards for elevated cone heads. v/ Hopper bottom steel silo come standard with a primed carbon steel pipe leg stand with silo floor plates and a standard 18" under clearance from the silo bottom to the silo floor plates. v/ That is to say, hopper bottom silo is your only choice if complete drainage is absolutely necessary.

  13. SMOOTH WALL SILOS v/ Smooth wall silos is cylindrical in shape from top to bottom. v/ Smooth wall silos are designed for bottom reclaiming. The followings are the advantages of KMEC smooth wall bins: Smooth wall design can help eliminating the bridging of materials in bottom unloading silos. The interior silo wall is smooth and all fasteners are located on the outside of the bin silos. Smooth wall bin design largely contributes to bridging problems since all wall sheet offsets, corrugations and bolt heads on inside walls are eliminated.
  14. Smooth walls are clean and have no contamination problems and this makes Smooth Wall Hopper Bin a good choice for food or grain storage. > Flange and angle silo wall construction which creates a smooth interior wall also provides tight joints while permitting normal expansion and contraction from radical ambient temperature changes and when absorbing foreign vibrations.
  15. SMOOTH WALL SILOS
  16. STAINLESS STEEL SILOS This type of silos are manufactured by stainless steel. v/ This style of silo adopts 4mm thick stainless steel, higher-grade coatings, screw seal and welding structure, which means less maintenance and long working life. v/ They have the ability to eliminate cross contamination and easy to install. v/ Stainless steel silos are widely in industrial areas especially Cement Industry and agricultural industry.
  17. SALIENT FEATURES OF STAINLESS STEEL Portability User-friendly Less maintenance Resistant to climatic variations Defect free Long working life Short construction period Trustworthy performance Ability to eliminate cross contamination Can withstand extensive use of open field

  19. CORRUGATED STEEL SILOS We manufacture a range of steel grain silos and metal silos that match with the highest quality standards and can be applied to various industries. v/ Corrugated steel grain silo is made from stainless steel (ripple steel sheet), known for high tensile strength and non reactivity. With experienced metal silo designing and constructing teams, we can promise long working life and less maintenance of it, offering our clients suitable silo system for a competitive price. v/ This corrugated steel grain silo can also meet the needs of portability, which means you can set the silo in place at the project site by using a crane.
  20. ADVANTAGES OF CORRUGATED STEEL SILOS Low request for foundation, low basic cost and low consumption of Steel. v/ High degree of standardization, easy to install, short assembling period. Equipped with conveyor, monitoring, drying and ventilation devices and this makes the storage safer and more automatic. v/ Long working period (more than 30 years). Easy to maintain. Our corrugated steel silo is easy to remove or repair since all the parts of the silo are connected by standard bolts.

  25. WELDED SILOS KMEC's welded silos are constructed without gaskets, seams and bolts, eliminating material hang up problems. v/ For welded epoxy-coated carbon steel silos, the outside wall must be primed and enamel coated to prevent rusting and the inside wall must be epoxy coated to keep away from contamination. But for welded stainless steel silos, there is no need of any internal epoxy coating or external painting.
  26. BOLTED STEEL SILOS v/ Due to our stainless steel fabrication and carbon steel with factory- baked protective coatings, along with a great selection of hardware and gasketing, we can ensure the quality of our bolted steel silo and offer our clients reliable storage solutions for various applications. v/ For additional protection, bolted steel silos are supposed to utilize plastic encapsulated bolt heads and nut caps.

  31. TOWER SILOS Advanced tower silos are strong enough to withstand wind and storm damage. Furthermore, quality control and on-site inspection is required during construction. In generally, there are two styles of tower silo, one is tower silos with antennas (antennas are mounted on the outside wall) and the other is wireless silo tower with the antennas hidden (antennas are mounted inside or under a fiberglass roof). v/ Tower silos can also be designed with equipment rooms inside the silo. During the silo construction, we have quality control and on- site inspection to keep the strength and safety.
  32. v/ In old days, tall, bullet-shaped tower silos are used for storing forage crops for feeding animals. Over about 40 years, the design, construction and foundation have been largely improved. Small size silo fabricating may be not that difficult for contractor or distributor. But for large tower silos, experience, technical knowledge and thorough soil investigation is quite necessary. v/ That is to say, you are recommended to find a reliable and large tower silo manufacturer, so that you can get optimal silo plans and professional guidance. Besides, the properties of the foundation silos should also be taken into account in silo design.
