Embodiment 1

[0026] Titanium gypsum wet material and titanium gypsum dry material are used to make raw material balls. The titanium gypsum wet material is the filter mud titanium gypsum discharged from the current production, with a water content greater than 40%. The dry titanium gypsum material contains less than 15%. Blocky titanium gypsum.

[0027] Production steps such as figure 1 Shown:

[0028] Step 1); The titanium gypsum wet material and the titanium gypsum dry material are conveyed and measured by speed-regulating metering belts respectively. After the titanium gypsum dry material is measured, it is crushed into fine powder with a bottomless crusher. When the titanium gypsum dry material is crushed, it can pass Water dedusting collects and treats the dust in the crusher to avoid dust pollution. The fine powder granular titanium gypsum dry material and the measured titanium gypsum wet material are put into the secondary suspension mixer, and the secondary suspension mixer mixes...

Abstract

The invention relates to a method for manufacturing raw material balls by reusing industrial waste mud titanium gypsum and a method for manufacturing cement raw materials, belonging to the field of waste mineral reuse. The method is as follows: a titanium gypsum dry material and a titanium gypsum wet material are mixed, and the water content of the mixed titanium gypsum is between 30 and 35 percent; the mixed titanium gypsum is put into a ball forming machine, by rolling the ball forming machine repeatedly, balls with a particle diameter of less than 3 cm are prepared from the mixed titanium gypsum, when the viscosity on the surface of the balls is eliminated, and the strength reaches a value greater than 0.3 MPa, and the ball titanium gypsum is air dried, wherein the strength after air drying reaches a value greater than 3 MPa. The viscosity of the raw material balls manufactured by the method is eliminated, the raw material balls do not stick to the ground, a belt, a bin and the like, and are convenient to dry and store; It is convenient to transport, does not stick to vehicles, and omits special transport vehicles. It can be used as a raw material for cement production after adding relevant components, can completely replace gypsum in cement production, saves mining of mineral raw materials, and achieves the purpose of recycling waste.

Description

technical field [0001] The invention relates to a method for reusing industrial waste mud titanium gypsum to make raw material balls and cement raw materials, and belongs to the field of reusing waste minerals. Background technique [0002] Titanium gypsum is the industrial waste mud produced by the production of titanium dioxide in chemical plants. It has a water content of about 40-55%, is non-toxic, has a high viscosity, and is iron red. Because it contains sulfur trioxide similar to gypsum, it is called "titanium gypsum" for short. . After long-term air-drying, the mud becomes lumpy after being piled up, and becomes powder after breaking up. Puffy, strong adhesion, high viscosity. [0003] According to the analysis of the chemical composition of titanium gypsum, it can be applied to cement production. However, due to the high viscosity of this solid waste, the titanium gypsum sent to the cement factory free of charge through the chemical plant has the following difficu...
