The principal disadvantage is that it can be considered crude or unhygienic and dangerous to health and the environment – it litters the railway lines and can convey serious ...
A wooden hopper for grain, on a millstone. Materials can be added either manually or automatically to the top of a hopper. For dust collection, it enters the hopper from a collection device. For example, baghouses are shaken or blown with compressed air to release caked-on dust from the bag. Precipitators use a rapping system to release the dirt.
