Embodiment 1

[0016] Prepare 1000 kg of the product of the present invention: take by weighing 50 kg of rare earth ore, 250 kg of fluorite ore, 200 kg of barium slag, 200 kg of copper slag, 200 kg of lead-zinc slag, and 100 kg of steel slag. The above-mentioned raw materials are crushed to 3-5mm, then sieved, measured, mixed evenly, measured, packaged and formulated into an energy-saving cement clinker fast-burning enhancer.

Embodiment 2

[0018] Prepare 1000 kg of the product of the present invention: take by weighing 150 kg of rare earth ore, 100 kg of fluorite ore, 300 kg of barium slag, 250 kg of copper slag, 150 kg of lead-zinc slag, and 50 kg of steel slag. The above-mentioned raw materials are crushed to 3-5mm, then sieved, measured, mixed evenly, measured, packaged and formulated into an energy-saving cement clinker fast-burning enhancer.

Embodiment 3

[0020] Prepare 1000 kg of the product of the present invention: take by weighing 100 kg of rare earth ore, 130 kg of fluorite ore, 300 kg of barium slag, 200 kg of copper slag, 200 kg of lead-zinc slag, and 70 kg of steel slag. The above-mentioned raw materials are crushed to 3-5mm, then sieved, measured, mixed evenly, measured, packaged and formulated into an energy-saving cement clinker fast-burning enhancer.

Abstract

The invention discloses an energy-saving cement clinker quick sintering intensifier, which is prepared into a finished product through the steps of crushing, screening, metering, uniformly mixing, metering and packing rear earth ores, fluorite mines, barium slag, copper slag, lead-zinc slag and steel slag which are in certain weight percentages. The energy-saving cement clinker quick sintering intensifier is a granular and powdery, nontoxic, harmless and radiation-free inorganic nonmetallic material which consists of a plurality of catalytic components and trace elements. When the product is used for a dry-process rotary kiln, the product can greatly improve the rate of dissolution of calcium carbonate, reduce the content of f-CaO, improve the yield per hour of the kiln by 10 to 30 percent, improve the early strength of clinkers by 3 to 7 MPa, keep the later strength of the clinkers about 60 MPa, reduce the sintering temperature of the clinkers by 50 to 100 DEG C, reduce coal consumption by 5 to 15 percent and reduce power consumption by 10 to 20 percent.

Description

technical field [0001] The invention relates to a cement clinker reinforcing agent, in particular to an energy-saving cement clinker quick-burning reinforcing agent used in the cement clinker firing process of a dry method rotary kiln. Background technique [0002] With the increase of national basic investment, the cement industry presents a situation of both production and sales. How to increase the output per kiln hour, reduce the energy consumption of cement production, and improve the quality of cement clinker has always been the goal pursued by researchers. At present, there is no catalytic material that can be used in the dry rotary kiln cement clinker production process, which can not only increase production but also save energy and strengthen. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving system that can increase the output of cement clinker, increase the strength of cement clinker, a...
