Problems solved by technology

[0004] The above-mentioned technology of lime powder into balls is mainly based on improving the compressive strength of lime powder balls, and the crush resistance, drop resistance and wear resistance of lime powder balls are not greatly improved. There are disadvantages of fragility and pulverization on the conveyor belt, and the broken lime powder balls seriously affect the recycling of lime powder balls

Abstract

The invention provides an anti-crushing anti-breaking lime powder ball. According to the invention, the anti-crushing and anti-breaking performances of the lime powder ball are improved by adding a small amount of artificial fibers in lime powder, thereby meeting the performance requirements of the lime powder ball for crushing resistance, breaking resistance, wear resistance and the like during transportation and conveying of the lime powder ball. Compared with conventional lime powder balls, the lime powder ball provided by the invention has higher bonding strength and better breaking resistance, can be recycled a plurality of times, and saves resources.

Description

technical field [0001] The invention relates to the field of preparing lime powder balls from lime powder, in particular to an anti-breaking and anti-shattering lime powder ball and a preparation method thereof. Background technique [0002] Lime is a basic chemical and construction raw material, also called quicklime, and its chemical composition is CaO. Generally, limestone or slaked lime of a certain specification is decomposed by high-temperature calcination. The annual output of lime in my country is more than 100 million tons. At present, industries that use active lime in large quantities, such as iron and steel industry and calcium carbide industry, all require lump lime of certain specifications because of technological requirements, so as to ensure safe, stable, high-quality and high-yield production. [0003] So far, the relatively mature technology in China is to process lime powder into spherical or granular lime blocks for utilization. According to whether a ...
