Problems solved by technology

When the raw meal mill is shut down, the kiln dust enrichment cycle in the raw meal homogenization storage causes large fluctuations in the raw meal rate value entering the kiln, which affects the easy-to-burn production of the raw meal entering the kiln

Embodiment 1

[0045] A kind of Portland cement clinker, the raw meal that is made by the limestone of 83.5 parts by weight, the sandstone debris of 9.5 parts by weight, the coal oil slag of 3 parts by weight, the steel slag grinding of 4 parts by weight, and mixes through It is formed by calcining 2.8 parts by weight of coal ash after burning.

Embodiment 2

[0047] A kind of Portland cement clinker, the raw meal that is made by the limestone of 80 weight parts, the sandstone debris of 7 weight parts, the coal oil residue of 4 weight parts, the steel slag batching grinding of 5 weight parts, and mixes It is formed by calcining 2.8 parts by weight of coal ash after burning.

Embodiment 3

[0049] A kind of Portland cement clinker, the raw material that is made by grinding of 85 parts by weight of limestone, 10 parts by weight of sandstone debris, 2 parts by weight of coal oil residue, and 6 parts by weight of steel slag, and mixed with It is obtained by calcining 2.8 parts by weight of coal ash after burning.

Abstract

The invention provides a Portland cement clinker with high compressive strength. A raw meal adopts the following components in percent by weight: 80%-85% of limestone, 2-4% of coal-to-oil residue, 7-12% of sandstone, and 2-6% of steel slag ingredients. New industrial solid waste coal slag is adopted as a substitute for a clay raw material to participate in a raw meal formula, natural non-renewableresources are saved, and the pain point problem of waste producing enterprises and government is solved. The three-day compressive strength value of the clinker can be increased to 37 MPa or more. Bythe unique raw meal homogenization technology, large fluctuation of a raw meal rate into a kiln caused by cyclic enrichment of kiln ash in a homogenization silo when a rotary kiln is started and a raw meal mill is stopped is avoided, continuous uniformity of raw meal ingredients into the kiln is ensured, and thus reliable guarantees for improvement of clinker strength are provided.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a Portland cement clinker with high compressive strength and a preparation method thereof. Background technique [0002] According to the requirements of GB / T21372-2008 "Universal Portland Cement Clinker", the three-day compressive strength of general Portland cement clinker can meet the requirements of the national standard. At present, the clinker strength of the domestic new dry process cement production line Most of them can reach between 26 and 33MPa. However, the current situation of the domestic cement industry is that the production capacity is seriously overcapacitated and the market competition is becoming increasingly fierce. All enterprises rely on their own product quality to continuously optimize and improve to strive for market share. [0003] Because clinker is the main source of cement strength and also the main component of cement compone...
