Kant Cement begins development of new limestone mine
18 July 2022Kyrgyzstan: Kant Cement has begun excavating the Severnaya Gryada limestone deposit near to its Kant cement plant. The producer says that the limestone has a higher purity than that from its existing Agalatas mine.

Kant Cement currently replaces a part of the limestone in the plant’s cement production with 65,000t/yr of fly ash.
UK: Aggregate Industries and Coomtech have partnered to develop low-energy kinetic drying technology for pulverised fuel ash (PFA) from power plant. The partnership will see Aggregate Industries use Coomtech’s kinetic dryers in its PFA processing, as part of its effort towards increasing the volume of waste materials incorporated in its products to 3Mt/yr from 1.5Mt/yr by 2025. The project has attracted funding from the UK government Department of Business, Energy and Industrial Strategy (BEIS).
Chief commercial officer Chris Every said “We’re delighted to have the support of Aggregate Industries in this grant project. Coomtech is especially pleased to have the business’ ongoing technical and commercial input to the project operation and analysis of performance. In addition, the opportunity to work together with a brand that is leading the way in creating new materials that will prove fundamental to the future of the construction sector and meet net zero objectives.” Every continued “The added benefit of our new drying technology is its flexibility - providing the potential to dry a wide range of materials being considered to aid the greening of the cement industry, including limestone, ground blast furnace slag (GBFS), natural pozzolans and other crushed and milled minerals that can offer an activated character to combine in cement and concrete mixes.”
