SU629181A1 - Raw mixture for making cement clinker - Google Patents

Description

The invention relates to the field of cement production by the wet method and can be used in the cement and other industries where it is necessary to reduce the water consumption of the ground materials or the viscosity of the suspensions, as well as to provide equipment corrosion protection.

The known raw mix for the production of cement clinker, including sodium tripolyphosphate II as a diluent.

Its disadvantage is an insufficient reduction in the water content of the mixture and equipment corrosion.

The known mixture for the production of cement clinker, including carbonate clay component, corrective additive and thinning naphthalene formaldehyde sulfate sodium in an amount of 0.025-0.1% 2. The disadvantage of this is insufficient effect of the dilution of the mixture, equipment corrosion and the duration of the grinding process.

The aim of the invention is to enhance the dilution effect, intensify the grinding process and protect the equipment from corrosion.

This is achieved by the fact that the mixture for the production of cement clinker, including carbonate, clay components, a corrective additive and a thinner, additionally contains higher unsaturated fatty acids or their salts in the following ratio, wt. %: Carbonate Compound72 - 81 nent

Clay component 17 - 26 Corrective

1-5 additive Thinner O, 1 - 1 Higher unsaturated fatty acids and their

0.001 - 0.0 salt

The thinning effect of the additive-thinner is enhanced by 4–60% with an increase in the surface area of the particles of raw materials due to the increased contacts of the adsorption layer of surfactants with the liquid phase. Popes of the raw mixture with increased dispersion without reducing the productivity of the mop with its help, introduce tappo maspo, sodium hypotone, or oleic acid in the amount of 0.001-0.05% by weight of dry matter. The mixture is prepared as follows. Before grinding, tall oil, or sodium oatum, or oleic acid is introduced into the blend, and a thinner is added to the mixture at the outlet of the grinding unit or into its second chamber. Additives in the form of a liquid are introduced into the raw meal mixture in the usual way using metering devices. In tab. 1 shows examples of the raw mix and the results of testing it.
