双螺旋磨浆机（国外称之为bivis机）采用挤压机械法制浆，其利用两根平行、同向旋转且相互啮合的组合式螺旋辊，使所处理的浆料纤维受到挤压、搓磨，纤维受到强化处理，进而实现纤维分离、帚化、分丝，完成磨浆作用。同时还可完成高效混合、脱水、洗涤等功能。可广泛应用于：化学机械浆和半化学浆等高得率浆生产；高浓漂白浆料与药液混合；废纸浆的离解；棉、麻浆的制浆；纤维板行业的浆料磨解；抄前纸浆的高浓预磨等方面。
与现有制浆设备相比，具有独到的优点。
A：磨浆质量高 B：节能20-50% C：节水80-90% 污染轻 D：药品利用率高，节省化学药品
E：制浆生产线投资少 F：原料适应性强 G：可将漂白和制浆合二为一，制浆的同时完成漂白过程
机器占地面积小，设备投资少工艺流程紧凑，生产能耗低，生产废水不含硫，不含氯，无污染。
Double helix grinding machine (referred to as foreign bivis machine) using extrusion machinery pulping, the use of two parallel, with the rotation to mesh with each other and the combined roll spiral, so that the processing of pulp fiber by extrusion, twist Mill, enhanced by fiber processing, fiber and thus achieve separation, broom, silk hours to complete the grinding effect. At the same time can complete high-performance mixed, dehydration, washing and other functions. Can be used: chemical mechanical pulp and semi-chemical pulp production of high-yield pulp; high-concentration bleach solution mixed with slurry; waste from the pulp of the solution; cotton, Ma's pulp and pulp; fiber pulp mill industry solution; Copy before the high concentration of the pulp mill in advance, and so on.
Pulp and compared with existing equipment, has unique advantages.
A: Refining the high quality of B: energy-saving 20-50% C: water-saving 80-90% of the light pollution D: Drug utilization, saving chemicals
E: less investment in pulp production line F: raw materials adaptable G: pulping and bleaching can be combined, at the same time the pulp bleaching process
Small footprint machinery and equipment investment in less compact process, the production of low energy consumption, waste production and not content, not chlorine, pollution-free.
