It provides controlled mechanical treatment to pulp, allowing accurate evaluation of fiber quality, consistency, and handsheet properties.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

        Samples are withdrawn from the beater at regular intervals and made into laboratory handsheets. The physical properties of these handsheets, such as tensile strength, tear resistance, and smoothness, are analyzed to construct a beater curve<\/strong> showing the degree of refining over time.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
