The hydraulic headbox is suitable for the speed of 320-1200m/min. Pulp is evenly distributed through the cone-shaped main pipe to step-changing tube . The dilution water is injected into pulp before pulp enters the stepped tube for adjusting the concentration and to improve the quantitative of the entire paper web.
