Summary:A processing method for making controllable low strength backfill material, which comprises the steps of: A setting step: setting an initial viscosity value of the initial material; A pickling operation step: stirring the initial material, a water and an acid solution in accordance with an initial proportion to uniform, and immediately adjusting the acid-base value proportion in the pickling process; A certain amount of output steps: using buffer slot as buffer to output quantitatively; A filtering step: filtering the fine particles of the slurry output from the buffer slot; A drying step for removing water to form a dry solid; A mixing and crushing step for crushing the dry solid to form a powder; as well as A heat treatment step: Cracking the organic matter in the powder to make controllable low strength backfill material.
