Bradley Pulverizer was founded in 1886 in Boston, Massachusetts. Our first single roll pulverizers were used in fertilizer plants grinding phosphate rock and in cement plants grinding raw material and clinker. To meet the growing demand of the fertilizer and cement industries, Bradley Pulverizer quickly expanded its pulverizing mill offerings.

The production of clinker is the most energy intensive stage in cement manufacture. Additionally, large amounts of CO 2 are emitted as a result of the calcination reaction. If less clinker is used per tonne of cement, significant savings in both energy and CO 2 emissions can be achieved [46].Hydraulic cements can be grouped into three main types: Ordinary Portland cement, …
To reduce energy consumption during clinker grinding, the concept of self-pulverized clinker has emerged. The characteristic volume expansion during the transformation from β-C 2 S to γ-C 2 S has been utilized in the preparation and development of self-pulverized clinker [20], [21].SPLCC, a self-pulverized low-calcium clinker system comprising C 3 S 2-γ-C 2 …
