Abstract

A raw material for processing fused magnesia and a preparation method thereof, comprising the following raw materials in parts by weight: 40-50 parts of flotation powder with a particle size of ≤2 mm, 20-30 parts of magnesite powder with a particle size of ≤15 mm, granules 20-30 parts of electro-fused magnesium smelting auxiliary materials with a diameter of ≤10 mm, 10-15 parts of light-burned magnesium oxide powder with a particle size of ≤1 mm, and 10-15 parts of water. Compared with the prior art, the beneficial effect of the present invention is that the present invention can effectively improve the ball forming rate and the strength of finished balls without adding chemical binders, and avoid the problems of increased production cost due to the addition of chemical binders and the production cost in electrical appliances. Environmental pollution problems of binders in fused magnesia smelting process. In addition, the present invention solves the problem that the mixing time and pressing time in the briquetting process do not match, causing the compactor and the briquetting machine to wait for the mixed material to run without load and waste electric energy.

Description

technical field [0001] The invention relates to the technical field of refractory production, in particular to a raw material for processing fused magnesia and a preparation method thereof. Background technique [0002] At present, due to the resource integration of magnesite mines by the state, the mining area is required to carry out restorative, rational and orderly mining, and to make secondary use of the white waste generated in the previous mining, that is, low-grade magnesite. The flotation powder produced by these low-grade magnesites is used as a kind of raw material by most fused magnesia processing industries. The main equipment for processing fused magnesia raw materials is composed of electrical supporting equipment such as mixer mill, conveyor belt, compactor, ball press machine and vibrating screen. Flotation ore powder, light-burned magnesium powder, fused magnesium smelting auxiliary materials (back-fired materials) and binders are used as the main raw mate...
