The present invention relates to an SCC having an enhanced mobility of a removal object by a distance between upper levels being wider than that of lower levels. The present invention provides the SCC, comprising: a housing having a rotary shaft; at least one reaction substance supply portion which is formed inside the housing; spinning cones, at least two of which are installed on the rotary shaft so as to have a specific tilted angle from an upper end to a lower end, for transferring a reaction substance that is supplied by the reaction substance supply potion, and for rotating with the rotary shaft at the center; fixing cones, which are fixedly formed on an inner surface of the housing, and are positioned on the lower end of each of the spinning cones that provide a path for sequentially transferring the reaction substance from the spinning cone at the upper end to the spinning cone at the lower end; a product collection portion for collecting the reaction substance which is transferred through the spinning cones and the fixing cones; and a driving portion for rotating the spinning cones, wherein one pair of consisting of the spinning cone and the fixing cone is considered to comprise a level, at least one distance between the upper levels is wider than that between lower levels. The SCC, according to the present invention, can improve the mobility of the removal object by the SCC having the at least one distance between the upper levels being wider than that between the lower levels.
