Crushing and recycling
The company Marián Balún BAPA has been engaged in quarrying and stone processing since 2007. Main activity of the company focuses on quarrying, processing, and sale of quarried stone. It also provides aggregates for use in bound and unbound mixtures and aggregates intended for sale to clients and to other consumers. Assortment of aggregates is certified under Act No 90/1998 on construction products in accordance with EN and STN.

Crushing and recycling
Since 2009 our company has decided to recycle construction waste (material to be reused) originating from demolition of buildings, industrial properties, highways, as well as from temporary slab roads.
Hydraulic hammer is capable of breaking stone and concrete up to a thickness of 60 cm. It is applied for breaking of concrete constructions, rocks, and the like.
Technological equipment for processing of construction waste should meet some of the essential requirements. The most important is the ability of crushing plant to process the biggest pieces of waste, separation of unsuitable admixtures, ensuring of required granulity of the material as well as to provide separation of reinforcing bar. An important factor in construction waste processing was an ability of the plant to get closer to the landfill, use of self-energy, possibility of sorting on required fractions as well as spraying for reduction of dust. Moreover, it has an ability of recycling of bituminous surfaces. Based on the criteria and requirements, we have decided to recycle with mobile crushing plant on a tracked undercarriage.
Crushed material is transported to sorting equipment - Mobile screen on a tracked undercarriage. Supply of the material to a dumping hopper is performed by front wheel loader or by caterpillar with backhoe buckets. All these equipments operate independently with minimum requirements on working area and operation. Spraying of landfill and of the material is used for dust control before the entry and after the exit of the crushing plant. Transport of such modified material is usually realised by large capacity vehicles to the treatment place or to the temporary storage of waste.
Recycling can be performed in the construction site or in the collection sites. Mobile technologies for recovery operations are used in demolition works. These are equipped with digital scales serving as a back control of recycled material for customers. Foreign material like for instance wood, plastics, metals, etc. is separated from the material produced in excavation and demolition works. Then, it is processed by crushing and sorted on fractions by size. The output is the ecological construction material that can be fully reused in construction or in many other industries.
