Embodiment 1

[0027] A kind of technology that utilizes ore leftovers to regenerate, its method steps are as follows,

[0028] 1) Choose leftovers and waste from mines or natural marble and granite production enterprises as the main material, and use cement and water as the batch material. One cubic meter of semi-finished products requires 450 kg of cement, 180-220 kg of water, and 1200-200 kg of main material. 1300 kg;

[0029] 2) Put the main material into the crushing equipment for crushing, then sort, and put it into the automatic batching equipment after passing it, add cement and water, and enter the mixing equipment for mixing;

[0030] 3) After the mixing is completed, put the raw materials into the static pressure molding equipment, and use the static pressure molding equipment for extrusion molding; the specific operation process is: first put the raw materials into the lower mold of the static pressure molding equipment, and use the upper mold to press down the raw materials For...

Embodiment 2

[0034] A kind of technology that utilizes ore leftovers to add colorant to carry out regeneration, its method step is as follows,

[0035] 1) Choose leftovers and waste from mines or natural marble and granite production enterprises as the main material, and use cement and water as the batch material. One cubic meter of semi-finished products requires 450 kg of cement, 180-220 kg of water, and 1200-200 kg of main material. 1300 kg;

[0036] 2) Put the main material into the crushing equipment for crushing, and then sort it. After passing the test, put it into the automatic batching equipment, add cement and water, and enter the mixing equipment for mixing; in the batching process, coloring materials and reflective materials are also added. All materials can be selected from commercially available products, or self-prepared color materials, wherein the self-prepared color materials are made of the following components by weight: 50 parts of nano-silicon carbide, 5 parts of nano...

Abstract

A process for regeneration of ore leftovers comprises the following steps: (1) selecting natural marbles and leftovers and scraps of granite manufacturers as main materials and adopting cement and water as batches; (2) throwing the main materials into crushing equipment to be crushed, then sorting the crushed main materials, throwing the qualified main materials into automatic blending equipment, adding cement and water, and stirring in stirring equipment; (3) after stirring, throwing the raw materials into static molding equipment, and performing extrusion molding by the static molding equipment to prepare products of different specifications; (4) stacking and curing the semi-finished products, wherein curing is carried out by three-stage temperatures, in the first stage, curing is conducted for 7 days at the temperature of 10-20 DEG C, in the second stage, curing is conducted for 15 days at the temperature of 0-10 DEG C, and in the third stage, curing is conducted for 20 days at the temperature of 0-10 DEG C; (5) after curing, planing, polishing and waxing to obtain the end product. The ore leftovers serve as kerbs and pavers, and natural marbles, granite leftovers and scraps are recovered and reutilized, so that waste of secondary resources is avoided.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a regeneration process using ore leftovers, and in particular to a method for preparing curbstones (side flat stones) and sidewalk bricks from natural marble and granite production enterprise leftovers and waste materials. Background technique [0002] With the progress of society and the continuous improvement of urban construction level, people's aesthetic concept is increasing day by day. Curb stones, side leveling stones, and pavement bricks, as a common pavement accessory material, are increasingly appearing in people's vision. At present, there are only two kinds of products in China, one is natural curb stones, side level stones and sidewalk bricks; the other is curb stones, side level stones and sidewalk bricks made of original concrete; Formed, and a waste of national mineral resources. The service life of raw concrete is short, the color is single, the prod...
