Powder dryer

The Problem

Powder dryer

A powder dryer was generating noise levels of 95dB. The majority of the noise emanated from the gearbox, which was bolted to an angled 'connector' plate. As a consequence the plate vibrates and behaves like a loud speaker cone and radiates noise. Gaps between the main drier body and the concrete supports also allowed noise to leak out.

The Solution

The Results

The noise levels were reduced by 8dB to 87dB.

The Costs

£4875 (2005 rates).
