Shaker-Type Dust Collectors
BCE has extensive experience designing, supplying, and installing solutions for mechanical shaker-type dust collectors.
How It Works: Mechanical shaker dust collectors have filter bags attached to a tubesheet at the bottom of the housing (at the hopper bin line) and suspended from horizontal bars at the top. Dusty air enters the hopper and is drawn into the bag interiors, where dust collects on the insides of the bags, and clean air passes through the bags and out of the collector.
Cleaning Process
Bags are cleaned off-line when a motor-driven shaft and cam vibrates the bars on which the bags are held, shaking off the dust cake. Shakers are generally used for intermittent or batch operations, but can operate continuously if the unit is compartmented, allowing one compartment at a time to be isolated for cleaning.
Advantages
- Simplicity of design
- No need for compressed air
- Good for applications where dust is easy to collect
- Can be used continuously if compartmented
Considerations
- Cleaning energy is low compared to pulse-jet collectors
- Air-to-cloth ratio must be kept relatively low
Expert Consultation: BCE can analyze your application and recommend whether a mechanical shaker dust collector is the right choice for your process and dust type.
