Abstract
The present invention relates to a production method of cement. In the course of production the slag is used as seed crystal and placed in other raw materials, and the weight of the slag is 0.3%-4% of total weight of the cement, so that it can reduce its production cost, and can protect environment, and the slag has the good fluxing function for calcination process. Said invented method is applicable to general vertical kiln, mechanical vertical kiln, also to dry or wet rotary kiln.
Description
The present invention relates to the Cement Production method.
Current many manufacture of cement producer all in raw material, add 0.3%-4% cement clinker, remove the liquid phase crystallization of inducing next samsara new as crystal seed, the fusion shielding effect that is produced when overcoming the high-temperature calcination pellet.Improve in the kiln and the ventilation and the calcination of pellet inside, have certain inducing action.But because after the cement clinker fine grinding, aquation very easily, after pre-watering granulation or pigment balling-up, most of and the reaction of water generation hydrate cause easy bonding pan-pelletizer, stop up tremie pipe and hopper.Formed what is more crystal water enters 1000 degree Celsius during high temperature at pellet, resolves into hydrogen and oxygen, often quick-fried kiln, nibble fire, play wind-tunnel, be unfavorable for the operation of kiln face, even cause work accident, cement clinker consumption is bigger simultaneously, causes waste, pays the huge duplication of labour.
Purpose of the present invention provides original technology of a kind of employing and equipment to the public, replaces the method for production of cement that cement clinker is made crystal seed with industrial slag.
The present invention realizes like this: adopt original technology and equipment, in the cement ingredient component, add crystal seed, crystal seed is the industrial slag of similar cement clinker crystallographic system structure homology material, in order to replace cement clinker, and slag is 0.3% to 4% of a cement slurry gross weight.They are Ferro Manganese sand or blast furnace slag or lead-zinc smelting slag or copper smelting slag or smelt the phosphorus ore slag or vitrifying cinder that bituminous coal obtained.
Advantage of the present invention: replaced the crystal seed that cement clinker is made manufacture of cement with industrial abandoned mine slag; calcination has been played fluxing action; not only protect environment but also reduced cost, both be applicable to cement ordinary shaft kiln, mechanical vertical kiln, also be suitable for the kiln that circles round of dry production or wet production.
Embodiment 1 does not change in ordinary shaft kiln Central Plains processing condition, under the situation that original equipment is not transformed, adds the Ferro Manganese slag that accounts for raw material total amount 0.5% to 3%, replaces cement clinker.
Embodiment 2 in the machine shaft kiln, adds the lead-zinc smelting slag that accounts for raw material gross weight 0.3% to 3% under technology and the immovable situation of equipment, replace the cement clinker crystal seed.
Embodiment 3 adds the smelting phosphorus ore slag that accounts for raw material gross weight 0.5% to 2%, in wet method is circled round kiln under technology and the immovable situation of equipment.
Embodiment 4 is with embodiment 1,2,2, do not change production technique and do not transform kiln, adds to account for raw material gross weight 0.5% to 3% produce cement in the dry back rotary kiln.
Claims (2)
1, a kind of Cement Production method adopts original technology and equipment, in the cement ingredient component, add crystal seed, it is characterized in that crystal seed is the industrial slag of similar cement clinker crystallographic system structure homology material, in order to replace cement clinker, slag is 0.3% to 4% of a cement slurry gross weight.
2, the method for a kind of manufacture of cement according to claim 1 is characterized in that slag is: Ferro Manganese sand or blast furnace slag or lead-zinc smelting slag or copper smelting slag or smelting phosphorus ore slag or the vitrifying cinder that bituminous coal obtained.
