AUSTRALIAN MADE CONE BOTTOM SILOS FOR EFFICIENT GRAIN STORAGE

Kotzur’s large elevated silos (cone bottom silos) are designed for efficient grain handling, fast unloading and flexible storage, making them ideal for a wide range of agricultural and industrial applications.

Manufactured in Australia and built to perform in harsh conditions, these silos combine gas-tight sealing, structural
strength and operational efficiency to deliver reliable performance across your grain storage system.

Whether you are operating a feedlot, processing facility or on-farm storage system, Kotzur provides cone bottom silos engineered for productivity and long-term value.

WHY CHOOSE KOTZUR ELEVATED SILOS

Cone bottom silos are a popular choice for operations that require frequent unloading, controlled flow and operational efficiency. Cone bottom silos are often preferred storage for pulses to reduce the risk of spits and gradings.

Key advantages include:

Rapid discharge through gravity-fed hopper design
Reduced reliance on mechanical unloading systems
Improved workflow and efficiency
Ideal for frequent grain movement and handling
Suitable for a wide range of grains and bulk

Cone bottom silos are commonly used in feedlots, grain processing, seed handling and commercial grain storage systems.

Wheat capacity based on typical consolidated/compacted bulk density in silo.
Max. Load based on engineering design for wheat at 920kg/m³ – this load will vary for products with differing properties.
Alternative (non Standard) Outlet heights are optional on all models.
Auger lengths are indicative only and are based on 35° angle. As differing auger brands elevate to different angles, always check individual auger height.
Nominal outlet height

Actual tonnage capacity achieved in silos will vary according to a number of factors including bulk density (test weight), angle of repose and headspace volume (for aeration).
