Basic Overview Of Bitumen Sprayers
What is a bitumen sprayer?
Bitumen sprayer machines are known as asphalt distributor and 
they help in controlled spraying of bitumen on the surface prior to 
the laying of hot mix asphalt. Whether it is construction of a new 
road or repair works, these machines form an indispensable part 
of any road contractor’s fleet. You will always need high quality 
equipment that will deliver as and when required so that you can 
get the task done with fewer efforts. Since this is going to use 
bitumen which is a sensitive material one has to be very careful 
with the selection of the equipment.
The property of bitumen is different and seasoned road 
contractors know that it has to be handled with care. 
Mismanagement can lead to accident and also wastage. 
Hence it is important that selection of any equipment is 
important. There are many companies offering bitumen 
sprayer for sale in India. But the million dollar question is: who 
is the better or who is more competitive or whose product is 
trust worthy? This can only be answered if one goes through 
the basic understanding of the machine, the manufacturing 
and testing process that a company uses and also the 
customer reviews that a company has got over the years.
The review has to be about the product performance from 
actual user + feedback and company’s service support 
rendered to the buyer during the use of the equipment.
What are the qualities that make a good bitumen 
sprayer truck?
One of the most basic quality and function of this equipment is 
to store bitumen in a tank, heat it when required and then 
spray the same in controlled quantity on the surface while the 
vehicle on which the entire setup is mounted moves slowly to 
make effective spraying. A complete bitumen spray tank has to 
be mounted on a truck chassis which can take it from one 
place to another while the spraying process is done.

SPRAYER CHASSIS: Sprayer chassis is built as per the truck 
chassis on which the bitumen sprayer is fitted. Depending on the 
width of the truck chassis, the width of the sprayer chassis is 
determined. The main tank and spraying unit is then fitted on the 
base chassis. This base chassis of the equipment can then be 
fitted to the customer’s vehicle at their site or at our factory.
TANKS: Tank for the bitumen sprayer is mounted on the main 
chassis. It occupies a large part of the chassis. Tank is one of 
the important components. The purpose of the tank is to hold 
the bitumen and heat it as and when required. This tank is 
fabricated with a 5 mm MS sheet and carefully welded to avoid 
any leakage. Over the tank a sheet of glasswool of 50 mm 
thickness is put. This is done to reduce the heat loss in the 
sprayer tank. Less heat loss means less fuel consumption 
required to heat the bitumen inside the spray tank = more profit. 
The outer sheet of the tank is a galvanized sheet. Galvanized 
sheet scores better in terms of anti corrosion and are better than 
regular MS sheet. The tank consists of internal coil which is 
used for heating the bitumen inside. A manhole on the tank for 
filling the tank is provided. The tank can also be filled from side 
as there is a three way cock given on one side of the machine. 
Manual and electronic temperature guage is provided with the 
equipment. Ladder is provided for ease of access to the tank’s 
top and drain out cock is also provided.
BURNER UNIT: Many bitumen sprayer manufacturers 
tend to ignore or play with this component. This unit is one 
of the important elements of the machine. It has to be of 
best quality possible. This high pressure oil burner should 
be capable of heating the contents of the tank quickly. 
There is also a small hand burner provided with the 
equipment. It is extremely useful in extreme cold conditions 
where chances of bitumen clogging are high or in some 
conditions where the spraying lines are not cleaned 
properly or adequately.
 ENGINE: This is a single stage twin cylinder air cooled diesel 
engine. It is of 25 HP power made by Kirloskar. The engine drives 
the bitumen pump and air compressor. Its fuel consumption is 
approximately 3-4 liters per hour. Considering the bitumen sprayer 
price, the components used by Atlas are all renowned.
BITUMEN PUMP AND AIR COMPRESSOR: Both bitumen pump 
and air compressor are engine driven. Bitumen pump is a gear type 
pump with capacity of 380-450 liters per minute. Hence it is very 
effective considering the spraying and also for fast filling of the 
tank. Air compressor is double cylinder and of reputed make. It is 
used for opening and closing of pneumatic valves and also for 
pressurized cleaning mechanism that uses air along with diesel.
SPRAYING SYSTEM: Spraying system consists of the 
spray bar and its ancillary components that help in open and 
close of the nozzles. Standard width of the spray bar with Atlas 
bitumen sprayer truck is of 2.4 meters. This is when the spray 
bar is closed. When the spray bar is opened the spray bar width 
is 4.2 meters which can give spraying of 4.5 meters. We are 
among few bitumen sprayer manufacturers that have 
successfully manufactured 6.0 meters spray bar. These spray 
bars have height and width adjustment facility. Depending on the 
conditions, you can adjust the width (2.4 meters or 4.5/6 meters) 
and also the spray bar can be taken up in case you are not 
going to use the machine for a long period 
of time or in case you are going to take the sprayer to a 
different place. By taking the spray bar up it will be more 
comfortable to run the truck at higher speed when not in use. 
By circulating preheated bitumen, it is also possible to heat the 
spray bar. It is important that all the quality machines are 
equipped with a hand spray pipe of suitable length. This is to 
cover up sides of the roads which may have been left out 
during the spraying process. A hand lever valve is provided 
near the operator’s chair. This pneumatic hand lever valve is 
useful for opening and closing of the spray nozzles of the 
bitumen sprayer machines.
CLEANING SYSTEM: Easy to use and effective cleaning 
system is the highlight of any good machine. Proper and 
effective cleaning system will ensure that the equipment is ready 
for next day’s use. Since this equipment is using bitumen and 
the properties of bitumen are such that it gets sticky and hard as 
its temperature lowers. This property of bitumen makes it very 
difficult to deal with as it tends to clog the pipelines with the drop 
in temperature. Effective cleaning system of the asphalt 
distributor consists of a simple process by using air and diesel. 
At the end of the day, the bitumen line has to be cut off and the 
spray bar can be cleaned by using a combination of air and 
diesel. This means that the lines are absolutely clean and the 
machine is ready to work when required.
TESTING PRIOR TO DISPATCH: Testing of bitumen sprayer 
prior to dispatch is one of the key factors that make a product 
very strong. Every sprayer that leaves our factory is factory 
checked and inspected and the end product that leaves is top 
notch quality. Tank is filled with water and spraying is done to 
check for leakages and optimum spraying of the machine.
A combination of these components manufactured with due 
care and by using quality materials will ensure that the machine 
manufactured will ensure quality and clean spraying.
