Abstract

The embodiment of the present invention provides a raw meal grinding aid for a vertical mill and a preparation method thereof. The raw material grinding aid provided by the embodiment of the present invention has a good grinding effect, and the percentage of 45 μm square hole sieve is as low as 11.3%. Under the same power consumption, the output per machine can be increased to 155t / h, and the clinker 28d strength can reach nearly 50MPa , The preparation method of the raw meal grinding aid provided by the embodiment of the present invention has a simple process, only needs to prepare polymerized polyol amine in advance, the preparation conditions are not harsh, and it is easy to promote industrialization.

Description

Technical field [0001] The invention belongs to the field of concrete technology, and more particularly to a raw material molcher and a preparation method for vertezed. Background technique [0002] During cement production, the raw materials need to be powdered. The raw flour grinding is under external force, by impacting, squeezing, grinding, etc., the internal strength between the stress and the mass point, so that the block material becomes a fine powder process. [0003] The raw material powder is the basic link in the process of cement production, which has a large impact on the subsequent link. For example, during subsequent clinker firing, the quality of raw material grinding will affect the coal consumption, power consumption, quality, and pollutant emissions of the clinker. These are the big items of clinker costs, overlapping Benefits may have a large increase. Therefore, it is therefore the same at all of the raw material to operate its multi-functionalization to the ...
