Storage Silo Cone Design Print E-mail
The Astec silo cone is exceptional. It prevents segregation and mix build-up with its mass-flow slope, it is equipped to resist wear, protected from heat loss, and its gate seals the silo for storage.

Cone Design Prevents Mix Segregation

Astec silo cones are taller and built with a steeper angle than other brands. The Astec design provides optimal material flow. Third party and Astec research shows the precise angle at which the entire column of mix flows down evenly to be 66°. The steeper angle of the cone provides true first-in/first-out inventory rotation, there is no mix buildup on silo walls, and mass flow loadout minimizes mix segregation. Mass flow occurs when mix flows out across the entire silo cross-section and that only happens with the correct cone angle.


Prevents Drops Into the Cone

If the mix level falls below the top of the cone, the level indicator signals the silo discharge gate to remain closed. To open the gate and empty the cone in this situation, you manually override the gate controls. This is because if mix dropped from the batcher is allowed to impact the cone directly it can cause unnecessary wear, or segregate on impact against sloped cone walls.


No Heat Loss Through Astec Cones

Unheated cones cause excessive mix heat loss. Our heating system operates during fill/run and storage modes. Together with the cone insulation the system works to keep mix in the cone hot.

A silicone electrical blanket surrounds the cone. A heat indicating controller turns the blanket on when the temperature drops below a selected point. This sensor saves you money because the energy to heat the cone is used only when required. Hot-oil heating is available as an alternative to the electric blanket.

Four inches of insulation on the outside of the cone's bottom portion help hold in the heat. A partition covered with a six-inch layer of insulation forms a warm, dead-air space around the top portion of the cone for even greater energy savings.


Protect Critical Areas

Mix can be abrasive and can wear on the area where the cylinder and silo cone meet. Astec lines this area with abrasion-resistant steel liners. Optional ceramic liners are available.
