Mobile stockyard Equipment can offer a cost efficient alternative to traditional stacker/reclaimer systems, especially for those developing new greenfield sites. The equipment is perfect for the initial "start-up phase" of the project, with the advantages of lower capital costs and no civil requirements/limited planning permission.
Typical operations in either developing a green-field site or upgrading a current stockyard operation would use a stacker/reclaimer system for all their needs in terms of stockpiling and reclaiming of the bulk material. There are many manufacturers of stacker/reclaiming systems worldwide with varying associated capital costs depending on the customers requirements. Also, other substantial costs associated with this type of installation includes civil requirements, planning permission, government legislation, etc., which further increase the capital expenditure and time frame of the project.
The mobile systems can offer a cost efficient alternative to stacker/reclaimer systems. Telestack specialise in the design, manufacture and installation of a complete range mobile stockyard management solutions for handling dry bulk materials. The range of equipment takes into consideration the "day to day" operational capabilities of any stockyard system, consisting of stockpiling, reclaiming, truck unloading and linking conveyors. The company's equipment offers the operator cost efficient solutions with high mobility and flexibility for any stockyard system.
The equipment is designed for operators handling up to 5 million tonnes per year with a single system, while still maintaining the required production capacities. For those upgrading their current system from an older stacker/reclaiming system to a new design, the robust design of the Telestack equipment ensures that the operator can maintain their current tonnage per year while limiting their capital expenditure. For those developing new Greenfield sites, this type of equipment is perfect for the initial "start-up phase" of the project. The lower capital costs and no civil requirements/limited planning permission are the main advantages of the equipment in comparison to fixed stacker/reclaiming systems. The equipment allows the operator to begin phase one of the stockyard very quickly and easy, with leads times on Telestack equipment as short as 12 weeks from order. All Telestack units can be packed into 40 ft containers for shipping globally and fully built on site within one week, with limited planning permission, civil requirements, etc.
The mobile equipment allows for a range of stockpiling requirements depending on the customer needs and height restrictions within the stockyard. The radial telescopic conveyors from Telestack are heavy duty stockpiling conveyors up to 58 metres length (190 ft) which allow for a maximum stockpile height of 20 metres and up to 200,000+ tonnes (based on 1.6 t/m3 density). The luffing (up/down) facility of the units allow the operator to use the units even in areas with restricted stockpile height. Also, the automatic PLC stockpiling system reduces the labour required to operate the equipment, while reducing the degradation, segregation, contamination and compaction of the material. The robust heavy duty design stockpiles up to 2500 tonnes per hour with the ability to handle a complete range of materials from coal/pet coke to iron ore which is ideal for multi-material stockyards. The mobility of the units are key to ensure production rates are maintained changing from one stockpile to another, Telestacks’ integrated tracked dolly units (see Fig. 2) ensure a highly mobile independent unit on harsh ground conditions within the stockyard. As seen in Fig. 3, the radial telescopic can be fed directly from the mobile link, reclaim and truck unloading conveyors to stockpile in the yard. The mobility allows the units to move back and around the stockyard to maximise the space / efficiency in the yard (see Fig. 3) as required, while limiting downtime in the stockpiling process.
