Superfine tailing instantaneous thermosetting granulation high-concentration filling system and method
According to the superfine tailings instantaneous thermosetting granulation high-concentration filling system and method, only graded fine tailings in superfine tailings are granulated, the overall particle size of the mixed tailings is remarkably increased, the concentration of filling slurry is remarkably increased under the condition that the fluidity of the filling slurry is not changed, and compared with traditional full-size-fraction tailings granulation, the particle size of the mixed tailings is remarkably increased; the granulation efficiency is obviously improved, and the granulation cost is reduced; graded fine tailings granulated particles and graded coarse tailings are mixed to prepare filling slurry, the supporting effect of the graded coarse tailings is fully utilized, granulated particle sedimentation is remarkably reduced, the stacking density is improved, and meanwhile the strength of a filling body is improved; by utilizing the instantaneous high temperature generated by microwaves and the thermophilic characteristic of the slag-based cementing material, the granulated particles are cured in a short time and obtain higher strength, so that the aim of instantaneous high-strength thermocuring is fulfilled; the method has the characteristics of high filling slurry preparation efficiency, low energy consumption, flexible equipment arrangement and easiness in concentration, and can effectively solve the problems of low superfine tailing filling concentration, large cementing material consumption, high filling cost and the like.
一种超细尾砂瞬时热固粒化高浓度充填系统及方法，仅将超细尾砂中的分级细尾砂进行粒化，显著提高混合后尾砂整体粒径，在充填料浆流动性不变情况下，显著提高充填料浆浓度，与传统全粒级尾砂制粒相比，显著提高制粒效率、降低制粒成本；通过将分级细尾砂粒化颗粒与分级粗尾砂混合制备充填料浆，充分利用分级粗尾砂承托作用，显著降低粒化颗粒沉降，提升堆积密度同时提高充填体强度；利用微波产生瞬时高温和矿渣基胶结料喜热特性，使粒化颗粒在短时间内实现固化并获得较高强度，达到瞬时高强度热固化目的；本发明具有充填料浆制备效率高、能耗低、设备布置灵活且易于集中的特点，能够有效解决超细尾砂充填浓度低、胶结料用量大、充填成本高等问题。
