Commercial Hopper Silo

General Information

If frequent unloading of stored grain is necessary, hopper bottom silos shall be choosen. Hopper angles may vary according to grain type to be stored, silo diameter and usage intention. Hopper structure prevents loss of time and money during the unloading period.

Hopper bottom silos can be separated into two sections. First ones which have low capacity are named Economic Hopper Bottom Silos and others which have high capacities Commercial Hopper Bottom Silos.

Commercial Hopper Bottom Silos’ diameters may vary from 4,58 m. to 11 m. and maximum capacity is 1800 m³.

Due to the high capacity, specially designed strong hopper structure bears the silo loads efficiently. All design details are considered for the safe grain storage.

Four different hopper angles as 37°, 40°, 45° and 60° can be manufactured according to silo diameter, grain to be stored, natural conditions of the place where silo is desired to be erected such as wind, seismic, snow loads.

High strength sidewalls provide firm and long-lasting structures by its min. 350 N/mm² tensile strength and optional 275, 350 or 450 gr./m² galvanized steel sheets which has a quality of EN S350GD+Z. Mysilo sidewall sheets have the most narrow corrugation in the world which is 65 mm.

Sidewall stiffeners are manufactured from S350GD+Z (min. 350 N/mm² tensile) high strength steel with optional zinc coating of 275, 350 or 450 gr/m². Transition of the vertical loads (dead load, load during loading or unloading, wind and seismic loads) of silo is very easy with these specially designed stiffeners.

Roof structure of silo is also specially designed and manufactured by using high strength steel with 275 gr/m² zinc coating. It provides an excellent sealing by fully overlapped, strong structure. Mysilo roofs are framed by sturdy beams. Beside standard roof models, custom designed roofs are available which can bear the specific loads such as different snow and wind loads according to the location.

High strength hardware is another reason why Mysilo products have long-life. Accordingly; DACROMET or JS-500 coated, Grade 10,9 hardware used both on sidewall and stiffener beams. Thanks to bonded washer and strip caulking, efficiency on sealing is obtained.

Safety on roof access is provided via Mysilo sidewall and roof ladders. Spacing between sidewall ladder and sidewall, embossing on the ladder rungs are specially designed for safety and not to slide. Resting platforms are located at certain levels according to related standards. Inside ladders are also available for maintenance and the controls inside silo. Mysilo also offers circular stair and specially designed roof ladders with hand-rails and stairs optionally which are more comfortable and safe equipments.

Silo access door is offered two pieces in each silo. First is utilized to access from roof when silo is loaded, other is located on second bottom ring for entering silo when silo is empty. Thanks to the inner cover of lower access-door; opening of the door is prevented when silo is loaded and safe usage is provided.

Grilled roof vents prevent bird entrance into silo. Vent quantity may vary according to silo diameter and grain type to be stored. Seams between roof panels and vents are sealed with high strength-special materials.

High sensitive temperature monitoring system is one of the unavoidable equipments for hassle-free stocking. Stored grain is always in danger of spoiling due to molding and insect occurring with the result of high temperature. Here comes the most sensitive temperature monitoring system; Mytemp.

Mysilo offers best solutions with its professional engineer staff.

* %6 grain compaction rate and 28° grain repose angle has been taken into consideration on capacity calculations.

** All silos are designed for the storage of grain and other free-flowing materials weighing up to 841 kg/m³.
