THERMOPLASTIC EXTRUSION AND AGGLOMERATE APPLICATION
From city areas to urban and interurban roads, the Borum Master 2000 can handle both smaller jobs and longer road stretches.
The BM 2000 T AG is an agile machine with excellent load abilities and a turning radius of only 3,2 m. It allows for material tank capacity of 265 L.
The BM 2000 has a one-seat slidable drive and operator section for flexible working on the left or right side.
The thermoplastic Borum extruder can apply lines of 5 – 40 cm width depending on the set-up. The extruder may be used for the application of various types of plain and profiled lines, single and double lines of different widths, as well as for simultaneous application of continuous and interrupted lines.
The thermoplastic agglomerate equipment can apply one line in widths up to 40 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 ready hot thermoplastic material through the extruder shutters onto the road surface. Glass beads can be automatically applied. The thickness of the line is controlled by the opening gap of the shutter and the speed of the machine, coupled to the thermoplastic feed rate. Thermoplastic extruder set-up ranging up to 30 or 40 cm total line width, built-up with 5 cm standard shutters (alternative shutter 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, lifetime is increased.
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 are 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 inactive extrusion shutters, 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.
