本机是一种新型造纸用除砂器，用于对造纸制浆进行除砂，包括相互连接的上锥体和下锥体，其上、下锥体分别有外支撑体和内部的陶瓷材料工作层，陶瓷材料工作层与外支撑体相互结合在一起。采用外支撑体和陶瓷材料工作层的组合结构，制作、装配方便，充分利用了陶瓷材料具有强度高、硬度大、抗腐蚀、耐磨性好等特点，大大延长了除砂器的使用寿命，经试验测试，可延长使用寿命达数十倍，减少了频频更换的麻烦，保证了正常生产，又降低了生产成本，避免了纤维流失，节约了材料，保证了纸浆成纸的质量。
当纸浆在一定的压力下从除砂器进水口以切向进入设备后，产生强烈的旋转运动，由于砂、纸浆密度不同，在离心力、向心力、浮力和流体曳力的作用下，使密度低的纸浆上升，由出水口排出，密度大的砂粒由设备底部的排污口排出，是一种利用离心原理去除浆料中的混合胶粘物、沙石、石蜡、热熔胶、塑料片、尘埃、泡沫、气体、铁屑、油墨离子等重、轻杂质的理想设备。
local is a new type of paper used desanding, pulp and paperused to carry out desanding, including the interconnection of thecone and the next cone, which, under the cone of the respectiveforeign and internal support working layer ceramic materials,ceramic materials and work-outside combination of mutual-support.use of outside support and the work of ceramic layer structure ofthe combination of manufacturing and assembly convenience, to makefull use of the ceramic materials with high strength, hardness,corrosion resistance, good wear characteristics, greatly extendedthe desanding"s life, after the pilot testing, extend the servicelife of up to 10 times that number, reducing the fre of trouble to ensure normal production and reduceproduction costs so as to avoid the loss of fiber, amaterial-saving, ensuring the of the paper into pulp.
when the pulp to a certain pressure from the inlet todesanding-cutting e to enter, have a strong rotation, asthe sand, pulp density, the centrifugal force, centripetal force,buoyancy and fluid drag role, so that low-density the increase inpulp from exhaust outlet, the density of the sand at the bottom ofthe device by the outfall discharge, the use of a centrifuge toremove the principle of mixed slurry stickies, sand, wax, hot-meltadhesives, plastic film , dust, foam, gas, iron filings, ink, andother heavy ions, light impurities in the ideal device.
