Not illustrated. 1907 Excerpt: ...is, perhaps, hardly descriptive of the various processes or treatments involved in the reduction of fibrous materials, and, perhaps, no comprehensive, term can be found for these several processes. These vary from actual cutting of the fibres in the manner of a pair of scissors to that of bruising and crushing, and between these two extremes we have the mere drawing out or separation of ultimate fibres, the flattening as by rolling, and splitting into fibrillae. All these different processes are involved in every case of beating, although the conditions of beating, as well as the nature of the material, assist to determine which is to predominate. The mechanics of beating is, therefore, complex, and incapable of scientific treatment, in so far that it does not lend itself to any form of numerical expression. 'Refining' and Refiners.--The operation of refining, as originally conducted, and as generally practised at the present time, is used for clearing the stuff, i.e. performing just that operation which is ordinarily conducted in the beater when the roll is lifted and made to brush out the stuff just before emptying. In such cases only a small amount of the power is expended in the refining operation. It has become the practice in some mills to put an increasing amount of work upon the refiner, and, consequently, less upon the beater. The 'Jordan, ' 'Home' and 'Marshall' refining engines consist essentially of hollow cones provided internally with fixed bars, in which rotates a solid cone provided with bars; the stuff passing between these bars is brushed out. If a small amount of brushing or clearing only is required the stuff is passed rapidly through, the reduction being controlled largely by the flow, but also by the pressure of the revolving bars again..
