In some cases the material traverses the chamber from the coolest to the hottest part on a conveyer or in wagons.
Guides are placed in front of the retort to direct its course to the coke hoppers or conveyer below, and to prevent scattering of the hot material.
You can either eat around the conveyer belt or there are some booths to sit in.
Crystals and precipitates, deprived of as much water as possible by centrifugal machines or filter-presses, are transported by means of a belt, screw, or other form of conveyer, on to trays staged in brick chambers heated directly by flue gases or steam pipes; the latter are easily controlled, and if the steam be superheated a temperature of 300Ã‚° and over may be maintained.
They are designed like conveyer belts and quickly transport the rider to the top of the hill.
