Jiangsu Liangyou Zhengda Co., Ltd is a professional enterprise engaged in steel silo equipment and storage engineering technology research, development, design, manufacturing and related products sales & service. Steel silo engineering could be applied in: food industry, feed industry, oil industry, building materials industry, brewing industry and port industry. FDSP is specialized in design, manufacture, installation for both domestic and foreign helix silo and bolt silo project.
Introduction about bolt silo:
fabricated by good quality hot-dip galvanized steel sheet(mass of Zn coat could be: 275g/㎡、350g/㎡、450g/㎡), adopt full automatic corrugated plate production line. The diameter of bolt silo could varied from φ2.75m toφ27.5m, height of straight part could varied from 1.12m to 20.16m, the storage volume could varied from 11m³ to 13333m³.
Temperature measuring system, ventilation system, indicator level system, circulation fumigation system inside the silo could be optional according to customer's need.
Based on the carried material, the silo could be divided into: maize steel silo, soybean steel silo, wheat steel silo, barley steel silo, sorghum steel silo, soybean meal steel silo, sawdust steel silo, biomass pellet steel silo. Also we can customized flour steel silo, cement steel silo, building materials steel silo;
Based on the hopper type, the silo could be divided into: concrete flat bottom steel silo, concrete cone hopper steel silo, steel structure support steel silo(single silo capacity should less than 1500T) .
This project is 1-2000T&1-3000T maize steel silo storage projec
The technological characteristics are as follows:
1、The main materials in silo are maize, the silo type is the bolt silo, for 2000T silo ,diameter is ￠12.8m, the height of the straight part is 20.16m, for 3000T silo, diameter is ￠14.6m, the height of the straight part is 21.28m, the base is concrete flat bottom.
2、The main process: unloading- storage - discharging
1)The unloading process the loaded by hydraulic back flip unloading, the grizzly cannot carry the truck. dumping hoper and dumping shed is equipped with de-dusting system to improve the working condition.
2) storage and discharging process: in this process, the main storage material is maize, there is temperature measuring and ventilation system inside the silo which could control the grain condition.
Features of the engineering process design:
1) adopt the hydraulic back flip loading according to customer's inquiry.
2) in this process, consider the large unloading capacity, there will be much dust in confined unloading shed when back-flip loading, so we make extra two de-dusting points on the top of unloading shed which closed to the dumping hopper besides the dedusting point on the dumping hopper.
(3) as the raw material for this customer is very clean so the cleaning system is not equipped in this project.
4) the silo base is designed as concrete flat bottom type, discharging by sweeping auger.
For different projects and different customer requirements, the process will be also different; the following could be options during the process design:
1)the customer required two different capacity silo in this project, but usually we suggest the silo in one project with same specifications.
(2) cleaning system (the cleaning system can be added before the material go into the silo if there is many impurities in raw material);
(3) ventilation and temperature measuring system (if the raw materials are relatively dry, and the storage time in the silo is less than 7 days in winter and less than 4 days in summer, this part can be removed);
(4) the silo changing system (if the storage time in the silo exceeds 60 days in winter and 30 days in summer, the warehouse changing system shall be considered);
(5) because of the site limitation and the customer need the same general height of two silo, we specially designed the 2000T silo with ￠12.8m×20.16m, 3000T silo with ￠14.6m×21.28m, but usually, we recommend 2000T silo with ￠14.6m×15.68m, 3000T silo with ￠16.5m×17.92m
6) customers can choose helix silo or bolt silo according to their own needs.
