Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] A high-efficiency cement production method (1) Sampling recovered shells to replace limestone to prepare cement at low temperature; shells can be widely recovered from various construction sites and waste rock material factories.

[0013] (2) Make shells, gypsum and kaolin into fine powder, put the three into a grinder and grind them into fine powder; first, you can put large pieces of shells, gypsum and kaolin into the gravel In the blender, stir into small fine stones, and then add the small fine blocks of the three into the stone grinder, and grind them into fine powder.

[0014] (3) Put the shells, gypsum and kaolin into the high-temperature furnace, heat the high-temperature furnace, and after the furnace temperature rises to a suitab...

Abstract

The invention discloses a production method of high-efficiency cement, relating to the field of building production. According to the method, shells are used instead of limestone as the substrate to fire the cement. The method comprises the following steps: making the shells, gypsum and kaolin into fine powder, respectively calcining in a high-temperature furnace in a ratio of 4:3:3, and finally, uniformly mixing. The method is economical and practical; and since the amount of the shells is not limited, the shells can be taken freely, thereby saving abundant cost.

Description

technical field [0001] The invention relates to the field of construction production, in particular to a production method of high-efficiency cement. Background technique [0002] Cement is a powdery hydraulic inorganic cementitious material. In recent years, due to the increase in investment in fixed assets, infrastructure construction and the rapid development of the real estate industry have significantly boosted cement production. Driven by huge demand, cement output will still maintain a relatively stable growth, and people's demand for cement is also increasing year by year. The patent application No. 200710137472.1 discloses a high-efficiency cement production method. Although the effect of cement is improved, the production process of cement is not changed, and the basic materials added are not changed. The cost is too high and uneconomical. Contents of the invention [0003] The purpose of the present invention is to provide a kind of high-efficiency cement pr...
