Silo Dischargers

Silo Dischargers or Silo Reclaimers vary in sizes and technology, depending on the capacity of the silo and stored materials. They enable efficient and reliable unloading of the coarse material with high controllability. Laitex design and manufactures tailored heavy-duty discharger solutions based on customers’ needs.

Silo Dischargers can be divided into two main groups: Screw Dischargers and Live Bottom.

Silo Screw Dischargers

Laitex Screw Dischargers can be used as a part of bulk material feeding and storing systems. The Screw Dischargers are a trouble-free solution for even the most demanding applications. For a maximum service life, all the exposed parts of the discharger are stainless or wear resistant steel. In addition to abrasion resistance, the functionality of the discharger is also improved.


Live Bottom for small volumes

A Live Bottom provides reliable feeding of various solid fuels. Typically Live Bottoms are used for small volume bulk material receiving applications, which require accurate and controlled dosing. The Live Bottom solution can be implemented including several screws depending on the fuel feeding requirements.
