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 method of making cement (1) Sampling recycled marble instead of limestone to prepare cement at low temperature; marble can be widely recovered from various construction sites and waste rock material factories.

[0013] (2) Make marble, 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 marble, gypsum and kaolin into the crushed stone 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 marble, gypsum and kaolin into a high-temperature furnace and heat the high-temperature furnace. After the furnace temperature rises to a suitable temperature, th...

Abstract

The invention discloses a cement preparation method and relates to the field of construction production. According to the method, recycled marble is used for replacing limestone so as to prepare cement at a low temperature. The method comprises the following steps: processing the marble, gypsum and kaolin into fine powder; separately calcining in a high-temperature furnace; finally, evenly mixing. Cost is saved greatly by utilizing the method, which conforms to the current slogans and calling very well.

Description

technical field [0001] The invention relates to the field of building production, in particular to a method for making 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. 200880118466.4 discloses a method of cement production. Although it plays a fixed role, the cost of the added basic materials such as hydraulic cement and carbon fiber is too high and uneconomical. Contents of the invention [0003] The purpose of the present invention is to provide a method for cement production to solve the above-mentioned technical defects caused in the prior art. [...
