Abstract
The present invention adopts the waste material of a fireproofing material as a main raw material for producing a grinding medium of aluminum oxide, which relates to a production technology of a grinding medium in the field of inorganic materials. Firstly, the waste material of the fireproofing material is used as the main raw material which is matched with other auxiliary raw materials for proportioning; secondly, the grinding medium with high performance can be sintered after mixing, granulating and shaping. With the method, the cost of the raw materials can be reduced considerably, and resources can be repeatedly utilized. The production technology is simple and convenient, and the performance of an obtained product achieves or even exceeds the performance of a grinding medium prepared from the aluminum oxide as the main raw material.
Description
Technical field
The present invention relates to adopt refractory materials is that main raw material is made grinding medium, and it relates to a kind of manufacturing technology of field of inorganic materials grinding medium.
Figure viewed from behind technology
Grinding medium is widely used in raw-material grinding of industry and processing such as cement, mineral, pottery, electronic material, magneticsubstance and coating, paint, makeup, food, pharmacy.The main raw material of grinding medium was an aluminum oxide in the past, and its market price is relatively more expensive.The content of aluminum oxide is very considerable in the refractory materials, and refractory materials factory after product is processed leftover bits and the refractory materials user waste and old refractory materials overwhelming majority that changes out all as refuse treatment.The present invention is a main raw material with refractory waste (roller rod, alumina firebrick etc.), is intended to save production cost, and realizes the recycling of resource.
Summary of the invention
The objective of the invention is to utilize refractory waste to be main raw material, be equipped with other fusing assistant manufacturing property grinding medium preferably, save production cost, realize the recycling of resource.
Concrete steps are as follows:
(1) earlier with the bulk of refractory waste coarse crushing to several millimeter, put into ball grinder ball milling a few hours then, take out dry for standby.
(2), be that main raw material is equipped with other auxiliary material clay, feldspar, lime carbonate, talcum and prepares burden with the refractory waste according to the requirement of prescription.Then prepare burden to insert and carry out batch mixing a few hours in the ball grinder.
(3) mud that mixes is dried, the porphyrize granulation.
(4) again powder machine-shaping, burn till then.
This invented technology is simple, convenient, and cost is low; It is the prepared grinding medium of main raw material that prepared product meets or exceeds with the aluminum oxide.
Embodiment
Example one
With the ceramic rod waste material is that main raw material is made grinding medium
1. earlier roller rod waste material (its chemical ingredients sees Table) coarse crushing granular to several millimeter, inserted in the ball grinder ball milling then 24 hours, the taking-up dry for standby.
2. require adding weight percent according to prescription is roller rod waste material behind 60% the ball milling, adds other auxiliary material again, clay, feldspar, lime carbonate, talcum.
3. the material that will prepare carried out batch mixing 4 hours, put into oven for drying, porphyrize granulation, moulding after the taking-up.
4. use chamber type electric resistance furnace at 1360 ℃ of sintering the porcelain base of forming.
5. carry out wear test relatively with prepared grinding medium and the commercially available grinding medium that with the aluminum oxide is main raw material makes, its performance reaches even is better than with the aluminum oxide is the prepared grinding medium of main raw material.
