Now a days Cement plants are producing 7580% PPC 2025% 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.

To fundamentally extend the service life of the gear, it is necessary to deal with the sealing problem, improve the basic structure of the gear cover, and make it difficult for sand and dust to enter the gear clearance. At the same time, the lining plate bolt structure should be improved to avoid sand from the root.
