Secure Discharging Structure
GSI offers commercial type discharging solutions for 24″ (7.31m) and 120″ (36.57m) diameter silos. Discharging spiral tube diameters may be 8″ (203.2mm), 10″ (254mm), or 12″ (304.8mm). If you are transporting excessive amounts of grain, even if you have a small silo, you may need a commercial type discharging system. For frequent use, thicker galvanized steel structure will make these types of discharging systems more endurable.
Commercial type scraping engine systems are produced by using 3/16″ (4.76mm) thick steel plates. All of the bearings are isolated, they may be arrayed on their own, they can be lubricated again and they are preserved in a cast block.
All of the caps operate with a geared cap control mechanism.
Only with a simple shaft changing operation both the central and the intermediary caps may be opened and closed.
In 48’ (14.63m) or larger silos, there are bottom-scraping transporters available. Transporter wheels move at the base of the silo and they assist in supporting the spiral and its protector. If your silo is 90’ (27.43m) or larger, then the transporter is comprised of two pieces.
Long-lasting, commercial silo discharge traps may be used for ventilation systems, which have bases that are entirely covered with perforated sheet metals, duct type ventilations systems or the ventilation systems that have been embedded in concrete. The traps are made of 1/4” (6.35mm) thick steel and due to the durable bearings, the traps can be easily opened and closed with only a slight amount of effort.
Engine Power Heads
Horizontal engine power heads are available in 6″ (152.4mm), 8″ (203.2mm), 10″ (254mm), and 12″ (304.8mm) dimensions. Depending on the unit, they can be directly pushed with single or double belts. Commercial types may have an operation system with 2, 3 or 4 belts or may have a oil bath reduction systems. 25° tilted power heads are used in those silos that have maximum 75´ (22.86m) diameters. They may have 6″ (152.4mm) (horizontal) and 6″ (152.4mm) (tilted), 6″ (152.4mm) and 8″ (203.2mm), 8″ (203.2mm) and 8″ (203.2mm), 8″ (203.2mm) and 10″ (254mm), or 10″ (254mm) and 12″ (304.8mm) dimensions.
If you want maximum capacity with regular grain flow, we would recommend you to use wider angled, tilted and smaller diameter, horizontal spiral system. 5´(1.52m) length provides approximately 2´ (.61m) extra discharge height. All of the tilted types are equipped with 2 or 3 belts and they also include an adjustable support table. Optional wheel kit can also be used to make the support table portable.
In 36´ (10.97m) diameter or smaller silos, 14´ 6″ (4.42m) with a standard vertical type spiral, discharge can be directly made to trucks, trailers or mills. These types of engine power heads require a single engine system in order to operate both vertical and horizontal type spiral below the silo. It is assembled to a vertically angled, oil bath gearbox. They can be operated either using a PTO unit or an electrical engine.
Within standard vertical type spiral package, there is a 3´ (.92m) long 45° tilted spiral tube, base support and silo wall assembly clamps. There is also an optional kit available to connect the 8″ (203.2mm) vertical type spiral to 6″ (152.4mm) discharge tube. 16´ 6″ (5.03m) long commercial type double engine vertical type spiral can be used in 24´ (7.32m) and 90´ (27.43m) diameter silos.
This system, which is offered with 8″ (203.2mm) and 10″ (254mm) diameters, is also equipped with a double engine system. Directly connected belt system engine or 3:1 ratio oil bath reduction system may be used to operate the engine in the horizontal section.
As in the standard type, within the package, there is a 3´ (.92m) long 45° discharge proclivity tube, base support and silo wall assembly clamps. There is also an optional kit to connect the 10″ (254mm) vertical type to 8″ (203.2mm) discharge tube.
Due to the rubber wheel, the spiral can be moved and the bottom scraper can touch the silo base.
The bearings provide the balance of the spiral at the grain weight kerf.
