Abstract
The present invention relates to a kind of copper ashes carbonaceous pelletizing molding NEW TYPE OF COMPOSITE binding agent, wherein comprise α starch and bentonite dry powder.These compound binding agent raw material sources are extensive, it is simple, with low cost to prepare, it is simple in extensively application and the popularization in mineral dust balling-up field；This compound binding agent is water-soluble dry powder material, it is easy to mix homogeneously with powder, meets water and is prone to dissolve and produce adhesive property, easy to use, simple to operate, beneficially large-scale industrial production.
Description
Technical field
The present invention relates to powder compacting bonding technology field, be specifically related to a kind of copper ashes carbonaceous pelletizing molding NEW TYPE OF COMPOSITE
Binding agent.
Background technology
The castaway slag that copper ashes produces during being primarily referred to as refining metallic copper, it is generation number in nonferrous metallurgical process
Measuring one of bigger, main several slags, annual adding up reaches tens million of ton.In copper ashes, the tenor such as Cu, Fe is higher, but
The smelted furnace cinder of most of copper smelting plants is not utilized effectively, but it is discarded for a long time and even store up in the wild, and this is not
Only cause a large amount of wastes of efficient portfolio, and produce certain environmental pollution and environmental protection pressure.Thus, how to realize copper ashes money
The later use in source and sustainable method battle array, reduction energy consumption, it is achieved economic, society and harmonious development have become society and enterprise
The task of top priority of development.
But, copper ashes is during recycling, it is necessary first to the problem solving its balling-up, current copper ashes carbonaceous pelletizing
Main employing paste is as binding agent, and pelletizing pulverization rate prepared by this binding agent is high, pelletizing cold strength is on the low side, this bonding simultaneously
Agent high expensive.
In prior art, the allocation of binding agent is the most more complicated, is applied to step during pelletizing molding cumbersome, is unfavorable for
Large-scale industrial production.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that one can meet copper ashes carbonaceous pelletizing performance and smelting
The compound binding agent of gold performance, these compound binding agent raw material sources are extensive, with low cost, easy to use, and utilize this compound viscous
Carbonaceous pelletizing intensity prepared by knot agent is high, can meet needs of production.
Specifically, the invention provides a kind of copper ashes carbonaceous pelletizing molding NEW TYPE OF COMPOSITE binding agent, wherein comprise α-
Starch and bentonite dry powder.
In order to improve the synergism of two kinds of compositions, improve the adhesive property of products obtained therefrom, the preferred described α-shallow lake of the present invention
Powder is 21～35:65～79 with the mass ratio of bentonite dry powder.
As a preferred embodiment of the present invention, described compound binding agent is made up of alphalise starch and bentonite dry powder.Described
In compound binding agent, the mass percent of alphalise starch is 21～35%, and bentonitic mass percent is 65～79%, the two it
With for 100%.
In order to make gained compound binding agent be prone to raw material to mix, convenient use, the grain of the preferred described each raw material of the present invention
Footpath is respectively less than 0.15mm.
The copper ashes carbonaceous pelletizing molding NEW TYPE OF COMPOSITE binding agent that the present invention provides has the advantage that this compound binding agent
Raw material sources are extensive, it is simple, with low cost to prepare, it is simple in extensively application and the popularization in mineral dust balling-up field；This is combined
Binding agent is water-soluble dry powder material, it is easy to mix homogeneously with powder, meets water and is prone to dissolve and produce adhesive property, adhesive property
Well, forming operation is simple, balling property good, and pelletizing pulverization rate is low, intensity is high, easy to use, simple to operate, the most extensive work
Industry produces.
Detailed description of the invention
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Embodiment 1
Weigh alphalise starch and the bentonite dry powder being smaller in size than 0.15mm, both mass percents are respectively 21%,
79%, uniformly mix above-mentioned material and prepare compound binding agent.
Embodiment 2
Weigh alphalise starch and the bentonite dry powder being smaller in size than 0.15mm, both mass percents are respectively 35%,
65%, uniformly mix above-mentioned material and prepare compound binding agent.
Embodiment 3
Weigh alphalise starch and the bentonite dry powder being smaller in size than 0.15mm, both mass percents are respectively 25%,
75%, uniformly mix above-mentioned material and prepare compound binding agent.
Although, used general explanation, detailed description of the invention and test, the present invention made detailed retouching
Stating, but on the basis of the present invention, can make some modifications or improvements it, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements without departing from theon the basis of the spirit of the present invention, belong to claimed
Scope.
