Preparation and production equipment for unclassified tailing filling material and preparation process

Abstract

The invention discloses preparation and production equipment for an unclassified tailing filling material. The preparation and production equipment comprises a high condensation product thickener (1), wherein the upper part of the high condensation product thickener (1) is connected with a concentrating mill thickener bottom flow pipe (10), and the bottom part of the high condensation product thickener (1) is connected with a sand tank through a thickener bottom conveying pipeline (2); the sand tank is connected with a coagulating, stirring and filling system through a sand discharging pipe (11); and the high condensation product thickener (1) is high efficiency and deeply conical, namely the bottom part of the high condensation product thickener (1) is a conical surface. Furthermore, the invention also discloses a preparation method adopted by the preparation and production equipment. Through the technical scheme, the novel efficient deep-cone thickener is used for preparing the full-fraction filling tailings, so that a continuous preparation of the filling material and an automatic control of the filling process are achieved; and the preparation and production equipment guarantees that overflow water quality meets the demand of recycling use of a concentrating mill.

Description

technical field [0001] The invention belongs to the technical field of mining production, and relates to the processing technology of industrial solid waste, more specifically, the invention relates to a production equipment for preparing full-size tailings filling materials. In addition, the present invention also relates to the preparation process of the production equipment. Background technique [0002] Traditional tailings filling only uses coarse-grained tailings, and fine-grained tailings are not used as filling materials. However, with the development of technology, and considering that fine mud tailings will easily cause safety problems when entering the tailings pond, the current trend of tailings filling is to carry out full-size tailings filling, and the preparation of full-size tailings filling It is a key technology of the filling system. [0003] The current vertical sand chamber preparation process requires the construction of multiple sand chambers, and th...
