THERMOPLASTIC EXTRUSION AND AGGLOMERATE APPLICATION
The Borum Master 3000 series provides you with a variety of high capacity line marking machines designed for large scale jobs such as marking highways, motorways or airport runways.
The material tank capacity can be up to 445L. The possibility for the large material capacity naturally gives fewer stops during the day for refilling.
The BM 3000 has a two-seat slidable drive and operator section for flexible working on the left or right side.
The thermoplastic Borum extruder can apply single and double lines of 5 – 50 cm width depending on the set-up.
The Agglomerate equipment can apply lines in widths up to 50 cm.
Line types that can be applied with this equipment
Non-pressurized thermoplastic tank indirectly heated via heat transfer oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically.
Diesel burner system for heating of the thermal oil (and thermoplastic). Propane burner available on demand.
Vertical agitator (mixer)
With hydraulic transmission. Heated center pipe for efficient uniform temperature control. Perfect melting & homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.
The working principle of the extruder lies in the extrusion of the hot thermoplastic material through the extruder valves onto the road surface. This allows to switch in between line types in seconds with a push of the button. No need for mechanical adjustment.
The thickness of the line is controlled by the slot gap and the speed of the machine, coupled to the thermoplastic feed rate.
Glass beads can be pre-mixed and/or automatically applied with glass bead guns.
You can choose between thermoplastic extruder of 30, 40, or 50 cm in total line width, built-up with 5 cm standard valves (alternative valve dimensions in the range of 4-10 cm for alternative line widths).
Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven. This ensures optimal performance and that the material does not stiffen and set inside the equipment.
The shutters do not touch the high tensile steel drum and therefore, this can lead to an increased lifetime.
Pneumatic lifting cylinder for up/down function, operation controlled from operator’s seat.
Pneumatically controlled quick cleaning function for the removal of solids left in the extrusion slots can be activated while extrusion is in process.
The application speed goes up to 8-10 km/h. Speed-dependent settings possible.
The transport of material from tank to extruder head is done by a hydraulically driven screw pump, which is electronically controlled. The screw pump has a permanent thermoplastic recirculation system which ensures a constant flow past the in-active extrusion valves, keeping these clean and ready for opening. This avoids settling and catching of solid parts and prevents unnecessary wear of mechanical parts.
Build-in pressure regulating system ensures that line width and thickness does not change no matter the number of the shutters involved in the current marking assignment.
Thermoplastic is a durable material that cures quickly and adheres strongly to the road surface. It can be used for applications of both flat lines (also known as type 1 lines) or of thick profiled lines and markings (also known as type 2 lines).
This type o material is used on various types of roads, but you will often see it on highways or motorways as it can outstand high traffic density, it has a high visibility at night and during wet conditions and glass beads can be mixed in for further enhancing visibility.
The Borum LineMaster control unit is an easy way of setting and controlling your line marking jobs. The LineMaster is attached to the operator's section of the machine and gives you full control of all your line marking tasks, from line application and pre-marking to reporting and invoicing.
It is possible to store up to 99 different line types, and to arrange these in up to 30 different marking programs. You are also able to pre-set line widths, line types, colours and combinations to have them ready for marking, and can instantly adjust them on the go.
Furthermore, you are able to view the status of various parts of the machine (e.g. compressor) on the computer screen that will help with correctly maintaining the machine and avoiding break downs.
Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. It can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of layer.
