Lowering Emissions
THE PLESOVICE PROJECT
BACKGROUND
Kámen a Písek spol. s r.o. is a company that operates in the aggregates sector and is one of the biggest in this sector in the Czech Republic. Kámen a písek s.r.o. is a subsidiary company of the Kirchdorfer Industries GmbH and produces around 1.5 millions tonnes per year.
Plesovice site is one of the biggest aggregate deposits in South Bohemia and provides reserves for 165 years. The aggregate is mainly used for the production of aggregates for rail and road as well as aggregates for concrete and coating mixture production.
ACTION
In 1992 the Kámen a Písek, spol s r.o. initiated a gradual upgrade of the site. In 2003 the company started to solve problems concerning the final products sorting line, material sorting quality, noise levels of the old sorting machines, sorting line dust nuisance and final sorting of elements smaller than 0,063mm from 0-4 mm fractions for coating plants.
The reconstruction was carried out in two stages. The first stage of reconstruction consisted of installation of new bearing structure with sorting machines, casing, exhaust, belt transporter and new sheathing. The second stage included the installation of a new cascade air separator intended for removal of elements smaller than 0,063 mm from 0-4 mm fractions.
RESULTS
As a result the production quality now meets European standards as well as the requirements for lower operating costs and quality products, lower noise levels, dust nuisance and emissions, better utilization of the raw material from the deposit and reduced secondary dust nuisance. In addition it will result in smaller mining areas in the future.
