Silica & Abrasives Handling

Silica powder handling is widely used in polycrystalline silicon or organic silicon production plants. The raw silica powder is unloaded and pneumatically transferred via inert gas or process gas to the destination. Due to the strong abrasive character of silica powder, the system needs special treatment for wear protection, such as wear resistant pipes and elbows, wear protected valves and others.

To avoid the potential blockage due to insufficient fluidizing, silica powder normally is transferred with an external by-pass system. Please refer to our dense phase powder technology for details.
