The India crushers market is poised for significant growth, driven by various factors. One of the primary drivers is the rapid urbanization and the expanding construction industry in the country. Crushers play a crucial role in processing and recycling construction and demolition waste, contributing to sustainable construction practices.
Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.
