Mining Construction Cement

Low heat cement is prepared by maintaining the percentage of tricalcium aluminate below 6% by increasing the proportion of C2S. This makes the concrete to produce low heat of hydration and thus is used in mass concrete construction like gravity dams, as the low heat of hydration prevents the cracking of concrete due to heat.

Our crushers are designed and built with advanced technology and stringent quality control at every stage of the manufacturing process, to meet the rigorous demands of aggregate operations.Our #1 goal is making the customer more productive and profitable by providing the best impactor-based technology and after-market support available.
