This section addresses the most general and relevant technical questions received by Borum's customer service department. We hope you will find the information helpful and informative. If you have a relevant question to Borum please mail it to firstname.lastname@example.org. Thank you.
Question: How do I find out which material to buy?
Answer: The recommendation of products is always a bit difficult because the composition of materials is different depending on the climate you are working in. In addition, the composition of materials can also differ from area to area. Therefore, materials coming from a supplier can have a different mixture depending on where they are being purchased. Overall, we recommend new customers to buy from well-known manufacturers that deliver in similar areas (in terms of climate, and the like). However, smaller local suppliers can also supply ok quality in accordance with the areas' requirements. Therefore, we recommend testing out different options.
Question: What line width can I apply with one Borum gun for airless cold paint application?
Answer: We offer a large selection of nozzle sizes for this type of application. The choice of a nozzle is made based on the capacity of the pump, a number of guns, application speed, layer thickness, and line type. For example, it is possible to spray 90 cm with 3 guns. The two outer guns with one size of nozzle, angled towards the center, and the center gun with a different nozzle, over spraying the other two, to give an even layer. We recommend contacting our Sales Department in order to determine the right nozzle size for your machine.
Question: What line width can I do with one Borum gun for spray plastic application?
Answer: For optimal line quality, we recommend the following specifications: - line width of up to 20 cm - 1 gun - line width between of 20 - 40 cm - 2 guns - line width between of 40 - 60 cm - 3 guns and one additional compressor Depending on the quality of the line you would like to obtain, you can apply a line width of 20-25 cm with one spray plastic gun. These recommendations are for both Borum self-propelled machines and trucks. However, on trucks, there is more room for making adjustments in terms of increasing the line width to 25 cm. Alternatively, we offer a narrow nozzle with which you can spray 5-15 cm with one gun.
Question: What line width can I apply with one Borum gun for automized cold paint application?
Answer: As standard, we offer the BM C-6 gun with our cold paint equipment. For optimal line quality, we recommend the following specifications: - a line width of up to 20 cm - 1 gun - a line width between of 20 - 40 cm - 2 guns - a line width between of 40 - 60 cm - 3 guns and one additional compressor Depending on the quality of the line you would like to obtain, you can apply a line width of 20-25 cm with one cold paint gun. There is more flexibility in terms of increasing the line width to 25 cm depending on work conditions, application speed, layer thickness, wind, etc. Optionally, we also offer Kamber guns with a wide range of nozzles sizes to choose between.
Question: Using Hot Spray Plastic, Twin guns for double line, approx how many metres per ton of Thermo plastic can our BM SP 350 do. We assume this will double up when using one gun!
Answer: Given line widths of 10 cm, double lines, and a line thickness of 1,5 mm you will be able to do 1667 m double lines with 1000 kg material – regardless of machine size! You are right – this will double up when making a single line using one gun only ;-)
Question: What is the required speed when yo use a Borum 250 / 350 / 500 machine for spray plastic and extrusion?
Answer: The application speed is the same regardless of the size of the machine. The application speed for spray and cold paint is up to 15 km/h. Normal speed is around 7-10 km /h (with cold paint the max speed is a little higher because of the lower viscosity and same max pressure on the tanks 8 bar). The best speed for extrusion is 3-6 km/h and max up to 8-10 km/h. With the screed box, the speed will be around 2-3 km/h.
Question: What will happen to the oil temperature of the hydraulic tank if it exceeds more than 80 degrees centigrade?
Answer: Normal work temperature is 60-80 degrees centigrade. If the oil gets too hot (more than 95 degrees. Centrigrade) it will lose the ability to lubricate and the lifetime of the oil will drop dramatically, and filters and gaskets can be damaged.
Question: Do you operate the Borum Megaroad the same way that you operate the selfpropelled machines. If not what is the difference?
Answer: All Borum machines are operated with the same kind of line controller and the same kind of equipment. There is only a small difference in the way it is handled.
Question: What is the main reason when the thermostats are malfunctioning? And what will happen to the thermostat in case of failure? How do I repair it?
Answer: If a thermostat is malfunctioning you need to replace it. In most cases, it will not turn on, but there is also a small risk that it will not turn oﬀ, and if both of them do that, the burner will keep on running, until something brakes or bursts into fire. Therefore it is very important to check the function of the thermostats during start-up and keep an eye on the temperature during the day. The thermostats are normally not repairable.
Question: How does the combination machine (equipped with thermoplastic extruder and pressurized cold paint) work?
Answer: Connect the cable from the equipment which you want to use to the computer and operate as normal.
Question: What is the difference between the self propelled and the Borum truck?
Answer: Some of the differences between the self-propelled machines and the trucks are: The self-propelled machines: • The operator and the driver is the same person • Smaller size, easier to get around with. • Easier to maintain a constant speed at low application speed. (Below 8 km/h) Truck mounted machines: • Bigger capacity, larger tanks • Faster transport operation, no loading and offloading. • Safety level for the workers is a bit higher; they are protected by the frame of the truck and are seated up higher. • Good at high application speed
Question: How far can you drive on battery with the BM 50 if the engine is turned off?
For how long can you drive on battery with the BM 50 if the engine is turned off?
Answer: Given the 6 km/h speed that you can reach with the BM 50, the machine can drive around 10-15 km on battery if the battery is full. However, the distance depends a lot on the driving conditions (e.g. if it’s a flat or inclined road, if you drive continuously or with stops, etc.). The BM 50 can drive a maximum of 2-3 hours on battery if the battery is full. However, the time depends a lot on the driving conditions (e.g. if it’s a flat or inclined road, if you drive continuously or with stops, etc.).
Question: Concerning the pins for the Borum Line Eraser, does it mean that the 24 pins is most suitable for thermoplastic and the 48 pins more suitable for cold paint?
Answer: As far as the LNX8 erasers go, the normal usage should yield about 40,000 Sq. Feet. Like any other piece of equipment, you must balance the speed VS equipment wear etc. and maximize their yield. As a general rule, you should: A. properly align the heads B. Only use the amount of down pressure required to erase the surface C. Set RPM to a slow speed initially and raise to increase yield to an acceptable level. The way we suggest for setting up the machine to get maximum value is as follows. 1. Start and warm up the machine on a flat level surface. 2. Using the elevation handle, raise the cutters up above the surface. 3. Using the long elevation handle, lower the cutters all the way down. 4. Use the aluminum elevation handle, begin to lower the cutters and watch for dust coming out of the machine. 5. Using the long elevation handle, lift the cutters off the work surface and move the machine away from the original position. You will now be able to see the pattern on the work surface comparable to crop circles. 6. If the circle is only partial, the machine should be adjusted to level the cutters. 7. On the front sides of the machine you will find 4 bolts which can be loosened with a 19MM wrench. Above these bolts they will find a pair of bolts and lock nuts. 8. Using a circle pattern for reference the customer may raise or lower either side or both sides to get the cutters to complete a full circle on the test surface. This may take a few minutes to adjust but the benefits are extended cutter life. The normal method of operation is pulling the machine backward while sweeping from side to side slightly. This has two benefits. It widens the erased path while feathering the edges to minimize surface damage. The leveling is a fairly important issue regarding cutter wear. Having the cutters hit in only a small contact area will necessitate adding un-needed pressure on the cutters heads to try to get a good removal rate. This also will accelerate the headwear which should be avoided.
Question: Concerning the pins for the Borum Line Eraser , does it mean that the 24 pins is most suitable for thermoplastic and the 48 pins more suitable for cold paint?
Answer: Yes, the 24 pins are designed for thermoplastic and the 48 for traffic paint.
Question: How many metres can we expect to get from 350 L machine and a 500 L machine per tank load? A) When doing Spray Plastic & B) When doing Thermo Extrusion?
Answer: BM 350 machine, tank capacity 350 l = 700 kg: • Hot spray plastic, a line width of 10 cm, single line, and a line thickness of 1,5 mm you will be able to do 2333 m with 700 kg material, which is one tank load. • Hot thermo extrusion, a line width of 10 cm, single line, and a line thickness of 2 mm you will be able to do 1750 m with 700 kg material, which is one tank load. • Hot thermo extrusion, a line width of 10 cm, single line, and a line thickness of 3 mm you will be able to do 1167 m with 700 kg material, which is one tank load. BM 500 machine, tank capacity 500 l = 1000 kg: • Hot spray plastic, line width of 10 cm, single line, and a line thickness of 1,5 mm you will be able to do 3333 m with 1000 kg material, which is one tank load. • Hot thermo extrusion, line width of 10 cm, single line, and a line thickness of 2 mm you will be able to do 2500 m with 1000 kg material, which is one tank load. • Hot thermo extrusion, line width of 10 cm, single line, and a line thickness of 3 mm you will be able to do 1667 m with 1000 kg material, which is one tank load.
Question: What is the approx total Litres or Gallons per ton of cold paint & Hot Thermo Plastic material?
Answer: Given a density of 1,6 kg/l for cold paint material, one ton of cold paint corresponds to approximately 625 l. Given a density of 2 kg/l for thermoplastic material, one ton of this corresponds to approximately 500 l.
Question: Using Hot Thermo Extrusion and making twin lines how many metres per ton can we expect?
Answer: This will change depending upon thickness of the Extrusion. Here are examples using 2mm & 3mm thickness of Extrusion. Given line widths of 10 cm, double lines, and a line thickness of 2 mm you will be able to do 1250 m double lines with 1000 kg material or 2500 m single line. Given line widths of 10 cm, double lines, and a line thickness of 3mm you will be able to do 834 m double lines with 1000 kg material or 1667 m single line.
Question: When using our BM C 350 Cold paint machine please give the Approx metres per ton of Cold paint.
Answer: Given a line width of 10 cm, single line, and a line thickness of 0,3 mm you will be able to do 20.833 m with 1000 kg material – regardless of machine size!
Question: What is the consumption per hour for BM T 250-2 and preheaters 2 x ID-600 with PS-15 pump station? We need this for calculating the cost of application.
Answer: Given the situation, we estimate that the machine uses approximately 25kW when using the extruder (The engine output is 36 kW which is being exploited when applying spray plastic at 10 km/h) This gives diesel oil consumption as follows: 25 kW à 270 g/kWh = 25 x270/0.86/1000 = 7,85 L/h. Approx. 8 L/h. The max. consumption of the burner is approx. 3,5 kg/h = 3,5/0,86 = 4 L/h. At a mean ambient temperature, the burner will be working approx. half of the time = 2 L/h Consumption of burners for 2 units ID 600 = each approx. 3 L/h = 6 L/h Hydraulic pump station, PS-15 for 2 units ID-600 = approx. 3 L/h. Consumption: Engine, BM T 250-2 = 8 L/h Burner for thermoplastic tank = 2 L/h Total for BM 250-2 10 L/h 2 units ID600 = 2x3 L/h = 6 L/h 1 unit PS-15 = 3 L/h Total for preheaters 9 L/h. NB! The capacity of the fuel tank of the BM 250-2 is 50 L, which corresponds to approx. 5 hours marking. The capacity of the tank of the PS-15 is 50 L, which corresponds to approx. 5,5 hours of operation.
Question: I work with a BM 250 road marking machine and have lately experienced a very slow reaction when starting to drive forward or reverse. What can I do to solve this problem?
Answer: • Some customers with BM 250 machines have experienced a very slow reaction when driving or reversing their machine. • After pushing the handle back or forth it could take 5-10 seconds before the machine starts to move! • The solution to this is to clean a small hole in the hydrostate – see the explanation on the photo.
Question: What is the difference between the two pre-marking systems?
Do you know the consumption of this system with aerosol (paint can)?
What are the advantages and disadvantages of each?
Answer: The difference between the two systems is that for the "Premarking system with paint can" pre-marking is done with an aerosol (so you have to buy aerosols) and for the "Pre-marking System with paintgun" there is a small tank to put the painting in and the application is done with a paint gun (as used for marking paint). A can of aerosol reaches approximately 1000-1200 meters. The pre-marking with a gun is cheaper to use and has a reach of approximately 2000 meters per refill. Some might say that using aerosol cans is easier.
