Grinding Mill Process Flow And Application of Volcanic Ash Vertical Mill

The grinding process of natural volcanic ash materials consumes a large amount of energy. After grinding, natural volcanic ash materials have irregular particles, multiple edges and corners, and a relatively small fluidity ratio. In addition, natural volcanic ash materials have relatively low activity as natural materials. Therefore, the vertical grinding of volcanic ash is an ideal new type of volcanic ash grinding mill equipment. As a manufacturer of volcanic ash vertical mills, HCMilling(Guilin Hongcheng) will introduce the process flow and application of volcanic ash vertical grinding mills.

Application of volcanic ash vertical mill: With the advancement of infrastructure construction in domestic civil engineering, water conservancy, transportation, and other fields, the consumption of concrete, as the largest civil engineering material, has reached 5 billion cubic meters worldwide. Adding mineral admixtures such as fly ash, slag powder, and silica fume to concrete can improve the workability of concrete, delay the rate of hydration and heat release, reduce concrete cracking, and improve concrete durability, It is one of the key technologies for achieving high-performance concrete. However, some countries or regions lack traditional mineral admixtures due to their developed industries. If they persist in using traditional mineral admixtures, they require long-distance transportation, high cost, and uncontrollable time, and there is an urgent need to find alternative materials. Natural volcanic ash material refers to a large amount of lava, debris, and dust deposited by volcanic eruptions on the ground surface or water to form loose or slightly cemented materials, including a wide range of volcanic ash, pumice, zeolite rock, basalt, andesite, tuff, diatomite, and so on. These natural volcanic ash materials are used as admixtures for concrete, and have similar effects to artificial volcanic ash materials such as fly ash, burnt clay, and burnt shale, and can be used as mineral admixtures.

The technological process of vertical grinding of volcanic ash powder: Take natural volcanic ash material sources and use 9.5mm and 16mm square mesh sieves for screening, and process them into smaller particles using a jaw crusher; Place natural volcanic ash materials ranging from 9.5 to 16 mm into a volcanic ash vertical grinding mill, and place composite mineral admixtures with a mass fraction of 10 to 20% of natural volcanic ash materials into a volcanic ash vertical grinding mill for mixed grinding; A natural volcanic ash material grinding additive with a mass fraction of 0.1 to 0.5% is put into the grinding mill equipment for grinding for 1-3 minutes to produce a finely ground natural volcanic ash material; The composite mineral admixture is made by mixing fly ash and silicon powder in a mass ratio of (70 to 80): (20 to 30); Volcanic ash vertical mill can reduce the energy consumption of natural volcanic ash material grinding process, and the processed natural volcanic ash material has better technical indicators, overcoming the shortcomings of large energy consumption and poor technical indicators of natural volcanic ash material grinding process.
