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) .
4-1500T & 2-2000T Grease Steel Silo Process
This project is 4-1500T&2-2000T oil processing factory storage project in oil industry; the technological characteristics are as follows:
1- The main materials in silo are raw material which can be used for oil extracting like maize, soybean and rapeseeds. 2000T silo is the bolt silo with diameter ￠14.6m, the height of the straight part is 15.68m, and the base is concrete all cone hopper. 1500T silo is the bolt silo with diameter ￠12.8m, the height of the straight part is 15.68m, and the base is concrete all cone hopper.
2- The main process: unloading-cleaning-buffering- drying- storage-bulk truck loading
1) unloading process is double side loading, the grizzly can carry the truck, two sided of dumping hoper is equipped with de-dusting system to improve the working condition.
2) cleaning process is equipped with double drum cleaner and tubular magnet with large capacity 80TPH
3) buffering and drying process: 1-500T bolt silo is for buffering, it will be a buffer for the speed difference between inlet and drying to reach the goal of quick loading, even drying.
4) storage process is 4-1500T&2-2000T bolt silo: the capacity for inlet is 40TPH, there is temperature measuring and ventilation system inside the silo which could control the grain condition.
5) bulk process: equipped with 1-75T soybean bolt silo, truck could pass and discharge through the bottom.
Features of the engineering process design:
(1) equipped with double drum cleaner specially used for cleaning maize and soybean, and also vibration screener for rapeseeds;
(2) When design the silo, the ventilation screen is designed to be detachable and easy to replace, so as to keep the air duct unobstructed and the good ventilation effect, effectively control the grain situation in the silo;
(3) the silo base is designed as concrete cone hopper type, the material can be discharged as their own gravity which can save equipment and power.
For different projects and different customer requirements, the process will be also different, the following could be options during the process design:
(1) cleaning system (this part can be removed if the raw materials are clean);
(2) 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);
(3) the cone hopper could also be concrete flat bottom, then the discharging could choose sweep auger based on customer's need.
(4) the silo changing system (if the raw material is dry and storage time in the silo exceeds 60 days in winter and 30 days in summer, the silo changing system shall be considered);
(5) customers can choose helix silo or bolt silo according to their own needs.
