  • PARTICLE SHAPE APPLICATION EXAMPLE: Portland Cement

    The challenge Portland cement is a controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients to which gypsum is added in the final grinding process to regulate the setting time. Lime and silica make up about 85% of the mass. Common among the materials used in its manufacture are limestone,

  • Effect of grinding method and particle size distribution

    These interactions can help or hinder the grinding process, and influence the relative content of each component in different size fractions and the particle size distribution of the ground products. As a result of these interactions, particle size distribution (PSD) of interground blended cements is different than that of separately ground
