In 2016 and 2018, Caleras San Juan S.A., based in the province of San Juan, Argentina, placed orders with Maerz Ofenbau AG for two Maerz PFR lime shaft kilns, a stationary crushing plant and a roller mill for grinding petroleum coke at its lime plant in Los Berros.
The two new E5-type kilns each produce 300 t/d of quicklime or dolomite and can be operated either with natural gas or petroleum coke.
Financing the project was a particular challenge for all those involved: after several years of negotiations with various European credit institutions and the Swiss Export Risk Insurance (SERV), the contract for the first kiln was awarded in 2016 - this kiln has been operating successfully since 2018.
Caleras San Juan is pursuing a consistent growth strategy and has decided to build another Maerz kiln at the end of 2021, again with a 300 t/d production capacity. For this new investment, too, Caleras San Juan has entered into financing agreements with its proven partners. The construction of a fourth kiln is the next expansion step.
