An improved hair dryer includes a fan unit and a heating unit to generate a linear heated air current which can mix with outside cold air to obtain a rotational air current of moderate temperature and to increase the capability of penetrating a user's hair. Therefore, the air provided by the hair dryer would not become both hot and dry, but maintain an ideal, moderate temperature suitable for users, so that users may feel more comfortable while dressing their hairs. Furthermore, the increased capability of penetrating a user's hair allows the hair to be dried more quickly.

Disclosed herein is a process for removing water from a particulate material selected from (oxy)hydroxides and carbonates containing at least one of nickel cobalt, and at least one metal other than nickel. The process includes the step of introducing at least one particulate material with a water content in the range of from 1 to 30% by weight, referring to said particulate material, into a rotary kiln with external heating elements and moving it through the rotary kiln together with a flow of a gas. The residual moisture of the resultant product is in the range of from 50 ppm to 1.5% by weight.

A shoe care apparatus includes an inner cabinet, a suction port, a discharge port, a connection flow path, a blower and a moisture absorbent block. The moisture absorbent block includes an inner mesh, an outer mesh and a moisture absorbent. A first flow path, which is a portion of the connection flow path, is provided inside the inner mesh, and a second flow path, which is a portion of the connection flow path, is provided outside the outer mesh. Air inside the inner cabinet flows into the connection flow path through the suction port, flows to the second flow path from the first flow path while passing through the moisture absorbent block, is dehumidified by means of the moisture absorbent block, and then is circulated inside of the shoe care apparatus while being discharged into the inner cabinet again through the discharge port.
