The 200 Ton Conical Bottom Steel Silo

The 200 ton conical bottom steel silo is a medium-sized storage equipment specially designed for the storage of large and medium-sized bulk materials, focusing on the sealed and fresh-keeping storage of grain, granular materials, and powder materials. The 45 ° cone bottom design ensures material self discharge, no residue or blockage. The warehouse is made of high zinc coated anti-corrosion steel plate, which is tightly sealed and has stable load-bearing capacity. It is equipped with standardized safety accessories, easy to assemble on site, controllable land occupation, strong durability and easy operation and maintenance. It is suitable for large-scale material turnover and long-term storage, and has a wide range of applicable scenarios.

Technical Parameters

No.	Item Category	Detailed Parameters & Configuration Description
1	Angle Design	Silo roof angle: 25°; cone bottom angle: 45°. The angle design fully complies with grain storage industry operation specifications.
2	Core Silo Body Specifications	Total silo volume: 275 m³; grain storage capacity: 206 tons; silo diameter: 5.5 m; overall height: 15.49 m; cylinder wall height: 10.15 m.
3	Plate Material & Layer Thickness	Silo roof plate: 1.0 mm cold-rolled Zinc-Aluminum-Magnesium SGC340 steel sheet, heat and corrosion resistance is 5 times that of ordinary galvanized steel sheet. Cylinder wall plates: High-quality double-sided galvanized corrugated steel plate BGH340/SGH440+275 from Handan Iron & Steel, spangle-free & oil-free, double-sided zinc coating weight 275 g/㎡. Layer thickness distribution: • Layer 1: 1.5 mm • Layer 2–3: 1.0 mm • Layer 4–7: 1.5 mm • Layer 8–9: 2.0 mm
4	External Column Specification	External M-type galvanized columns, unfolded width approx. 312 mm. Section thickness by segments: • Section 1–2: 3.0 mm • Section 3–5: 4.0 mm Superior structural stability.
5	Steel Cone Bottom & Supporting Components	Whole steel cone bottom treated with anti-corrosion spray painting. • Column base: H-beam H200×150 • Tie bar: 63×6 angle steel • Cone bottom plate thickness: δ4–6 mm
6	Auxiliary Safety Facilities	Complete supporting safety accessories: • 1 set maintenance manhole on silo roof • 1 set silo access door on cylinder wall • 1 set vertical climbing ladder inside the silo • 1 extra vertical climbing ladder from ground to lower silo door (outside)
7	Installation Technology & Connection Configuration	On-site assembly mode. Silo corrugated plates are processed by cold rolling, punching, arc bending and cutting production lines with high manufacturing precision. Fasteners: Grade 8.8 high-strength galvanized bolts (brands: Shanghai Hardway, Jinyi) for silo roof and cylinder walls; Grade 10.9 upgraded high-strength galvanized bolts for key load-bearing positions. Sealing system: Waterproof, wear-resistant & anti-corrosion rubber nylon gaskets from Fujian Yongda for all bolts; Shanghai Kejian aviation sealing putty applied on wall plate joints — excellent corrosion resistance and airtightness. Designed service life: 30 years. Distinct from ordinary simple construction using standard bolts, common gaskets and regular rubber strips without aviation sealing treatment.

Product Uses

1. Large grain depots/grain storage centers: Suitable for cross season storage of wheat, corn, and rice in national grain depots and regional storage bases, with a large capacity of 300 tons to meet bulk storage needs. The 45 ° cone bottom is combined with mechanized unloading, greatly improving grain turnover efficiency and reducing storage losses by sealing and moisture-proof.

2. Large scale feed processing group: As a centralized transfer warehouse for core raw materials such as soybean meal, corn, and bran in large-scale feed factories, it reduces the frequency of feeding with large capacity, and the high anti-corrosion board is resistant to raw material corrosion. The self discharge seamlessly connects with the automated production line to ensure the continuity of large-scale production.

Product Advantage

1. Modular precision manufacturing and installation: Corrugated sheets are processed by automated cold rolling, punching, and bending production lines, with high dimensional accuracy; Modular assembly of the entire machine on-site, compact footprint, short construction period, supports parallel expansion of multiple warehouses, and is suitable for large-scale site layout.

2. Extra large load-bearing+safety reinforcement design: External thickened M-shaped galvanized columns are used to strengthen the load-bearing capacity, and key load-bearing parts are specially reinforced. The structure is stable under a full load of 300 tons, and safety accessories such as warehouse doors and straight ladders are standard. Daily inspections and material control are safe and convenient.
