Apeco supplies Kunda Nordic Tsement AS cutting edge technology for mixing aggregate

March 13, 2015

Kunda Nordic Tsement AS has recently invested in Apeco-produced technology for mixing aggregate. This modern equipment for mixing aggregate now makes it possible to produce various aggregate mixes more flexibly and to meet the ever-increasing quality requirements. The equipment is designed to produce various long fractions, or graded aggregate, at a rate of 400 t/h according to the grading curve required. High flexibility and an automated process boost productivity and efficiency across the entire production process. A modern automated system allows all of production to be monitored, ensuring a high-quality final product.

According to Riho Iskül, Development Director at Kunda Nordic Tsement AS, “The mixing unit is not something new to the world; however, in collaboration with Apeco, a bespoke suit, as it were, has been created for our company, its design tailored for our materials (both the aggregate and the binders produced). Our firm hope is for this equipment to take us to the next level in the production of aggregate.”

The aggregate mixing line also enables Estonian crushed limestone to be enriched very efficiently. For this, hydraulic road binder (HRB), or simply cement, is mixed into aggregate. Metered from a silo, cement or HRB is mixed into aggregate according to the recipe entered.

Thanks to its innovative solutions, all of the equipment is very easy to control and handle. Based on a previously stored recipe and with the support of an RFID card, the driver of a dumper truck can handle the entire loading process by himself with a single press of the button, which will activate the entire mixing line. With the equipment, the necessary quantity of material can be metered into the load bin of a dumper truck according to the order.

The owners of AS Kunda Nordic Tsement are HeidelbergCement Sweden AB (Sweden), who holds 75% of the shares and CRH Europe Holding BV (the Netherlands), who holds 25% of the shares.
