All the components of these silos are properly galvanized, along with the circular ring beam and the supporting leg structure. The bottom end of the silo features a flaccid concrete base. These galvanized silos are commonly used to store grains for a prolonged time without getting spoilt. A Galvanize flat bottom silo is much cheaper as compared to a hopper bottom kind of silo of identical capacity.


Such a silo is also provided with various high-end accessories like aeration system, level switches, discharge gates and temperature monitoring device. Pneucon designs these silos are taking into consideration various factors present on-site like cold, humidity, heavy rainfall, earthquake and hot region. We take a lot of care if the silo is to be placed in a seismic zone.



Flat bottom silos boast of several features. It is made of galvanized silo S350 GD which boasts high elastic resistance. A galvanize silo also has Z450 minimum coating that equals 450 g/m2 of zinc. Our entire product range of silos is equipped with 8.8 high quality dichromate bolts. These silos also have washers equipped with neoprene ensuring a watertight seal. Our galvanized silos’ exteriors are galvanized reinforced. Irrespective of the thickness, all have galvanized shatter-proof exteriors. This ensures complete protection against corrosion. On silo models that feature a diameter more than 12.22 meters, the roof structure is cross section galvanized.


We employ a strict, demanding method of calculating the thickness. The platforms and stairs used in the manufacture of a galvanize silo adhere to the European standard Directive 89/654/CEE.

We also excel in the manufacture of Galvanized Hopper Bottom. The storage capacity of these silos range from 13 m³ to 2000 m³. All the components of these silos are efficiently galvanized, including the circular ring beam and the supporting leg structure. The silo’s bottom end is in a conical hopper shape and measures either 60 degrees or 45 degrees depending on what kind of grain would be stored inside. The hopper angle of the silo is based the repose angle of the stored grain as well as some other characteristics.

The primary benefit of this silo is complete discharge of the grains stored inside owing to gravity. These silos are appropriate for day production along with Galvanized Flat Bottom Silos. These silos are equipped with different accessories like temperature monitoring system, aeration system, level switches and discharge gates. We design the silos keeping in mind various external climatic conditions like earthquake zone, hot, cold, humidity, heavy rain and snow climatic conditions.

We manufacture hopper bottom silos with galvanized steel S350GD that are highly elastic tolerant and also with Z450 minimum coating same as 450 g/m2 zinc. These silos also feature a hot dip galvanized leg support mechanism. For more details please Click Here……

Horizontal Silo manufacturer

Pneucon’s horizontal silos are commonly used for storing cement and other heavy construction materials. Pneucon manufactures these horizontal silos from mild steel plate which are molded in a way that the material is dropped into the horizontally shaped screw conveyor fixed on the lower end of the bin. The material is extracted by the horizontal screw conveyor and transferred to the inclined screw conveyor. Following this, the material is discharged from a height of 4.2 meters. Pneucon’s horizontal silos feature a control panel which is useful for the horizontal screw conveyor, vibrators and the inclined screw conveyor. The control panel can be operated automatically while batching a defined cement quantity out from the silo or manually operated through push buttons.


The weight indicator on the horizontal silo displays the net weight of the stored cement inside the silo. It also enables accurate and quick calibration of the load cells. The cement’s pre-set quantity can be batched out automatically on loss- in-weight basis just with a single hit button that can be operated from the display panel. The same procedure also can be manually done by separately operating all other dosing devices through push buttons that are found on the control panel. The accessories bin is held up electronic load cells. This bin effectively transfers the load to an appropriate framework.
The framework is equipped with offloading legs that are operated manually. As a reliable horizontal silo manufacturer, we provide horizontal silos with efficient vibrators for facilitating material flow, as well as flow of relief pipe, loading pipe, man hole and pressure relief valve. Pneucon’s horizontal silos are available in capacities of 20 tons, 30 tons and 4o tons. Our horizontal silos feature well engineered load cell weighing systems with advanced electronic instruments. Some other salient features of these silos are inclined screw conveyor, horizontal screw conveyor, electric control panel, pressure relief valve, relief pipe and loading pipe. The vibrators help to facilitate smooth material flow. These horizontal silos are feature a Man Hole and an optionally provided rear mounted dust filter.

Since then time we started business, we have earned a formidable reputation for developing an innovative concept for storage silos and are industry leaders when it comes to horizontal silos. For the clueless, horizontal silos are suited for temporary storage of granular and powder products. We can deliver the silo on a traditional flatbed vehicle and can be sited with a forklift, lorry-mounted crane or a simple crane.
We also excel in the production and design of a cement silo. Pneucon is a major company that produces it. We also excel in manufacturing concrete batching plants.

The PNEUCON Screw Pumps are heavy-duty, screw-type pneumatic pumps. These pump systems are most commonly used to convey dry, free-flowing, pulverized materials from grinding mills, transfer materials from silo to silo, transfer dust from collectors, and load and unload railcars, ships and barges. The materials are conveyed literally anywhere a pipeline can be run and to any number of delivery points.


General Specifications

PNEUCON Screw Pumps are constructed of mild and structural steel, and mounted on a base. PS pumps are equipped with pedestal blocks that support a pump screw which helps to provide a smooth, balanced operation. The screw is dynamically balanced and areas of this screw, along with other parts of the pump in direct contact with the material to be conveyed, are made of hardened, wear-resistant material and special hard surfacing where required. The screw is directly coupled to the driving motor but can be v-belt driven.

Standard equipment on PS pumps includes a pressurized seal and bearing assembly that extends the service life of the discharge seals by preventing the material being handled from entering the bearing area. Each pump system includes the pump, drive motor and compressed air source.


The materials to be conveyed enter the hopper by gravity or dumped by any means. The material is compacted as it is advanced. Its density is further increased in the space between the terminal flight of the screw and the face of the non-return valve to form a seal against the transport line pressure, thus preventing blowback. The material then enters the discharge body, is fluidized by compressed air, and is conveyed into the transport line.
