Seite 25 - ... at both ends, which is set in a horizontal position, and contains an axis with iron arms, their revolution serving to break up the clay, which is charged through a hopper at the top. A current of water passes through the cylinder and carries the fine clay particles with it, while the coarse ones are left behind in the machine. The speed of the current has to be regulated by experiment, for if too much water is used coarse material will be washed out of the cylinder, and conversely if the current...

Seite 26 - The troughing has a slight pitch, commonly about one inch in 20 feet, but the amount depends on the kaolin and whether the contained sand is fine or coarse. If the kaolin is very fine and settles slowly, the pitch need not be so great, and vice versa. A large quantity of very coarse sand in the kaolin is a nuisance, as it clogs up the log washer and the upper end of the trough more quickly, causing much labor to keep them clean. As it is, considerable sand settles there, and to keep the trough clear,...

Seite 26 - ... on the second. If the vegetable matter and sticks are allowed to accumulate, they clog the screen, and prevent the kaolin from running through; consequently stationary screens must be closely watched. The revolving screens are far better; for they are self-cleansing. Such screens are barrel-shaped, and the water, with the kaolin in suspension, is discharged into the interior and passes outward through the screen cloth. As the screen revolves the dirt caught is carried upward and finally drops;...
Seite 152 - Lily White.' The specimens examined were, therefore, rather below the average quality, and on long exposure to the air their surface shows some yellowish spots. I found, nevertheless, that in baking at a high heat they yielded a biscuit of greater whiteness than their natural color when fresh, and that fine splinters exposed for ten minutes to the highest heat of the mouth blowpipe retained their shape perfectly while reduced to a .semitransparent grit. A quantitative analysis of the clay from Clingscale's...
