Excerpt from Report on the Gypsum Deposits of the Maritime ProvincesThe mixer is a machine having essentially two compartments, a' mixing chamber, and a sacking chamber. The mixer has one mixing shaft, with two sets of paddles so arranged that one set throws the material from the outside of the mixing chamber towards the centre, at the same time causing the material to travel towards one end of the mixing chamber, while the other set of paddles causes this operation to be reversed. All working parts are made of iron or steel. The main shaft and stufing hoses are made extra heavy, the main bear ing independent of the stufiing boxes. 'the mixer is provided with wooden receiving hopper, lined with sheet steel. By operating a lever the operator discharges the material from the hopper into the mixing chamber. After the material has been in the mixing chmsber a sufficient length of time (from 3 to 8 minutes) the operator, by turning a pilot wheel, opens the valves to the sack ing chamber, which allows the material-to discharge into the mking chamlet. This is made of wood, lined with sheet steel, and provided with an agitator to keep the material from clogging, it also allows the mixed product to be dis charged directly into sacks for shipping.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
