Top quality coatings of sports floors having an EPDM granulate
upper surface requires a lot of know-how and special
experience of spreading. For a perfect surface with
secure coverage of the coating material, an even application
layer and a sufficient quantity of granulate are absolutely
essential.
The special challenge faced during the careful spreading
required for the installation of a running track is to provide
large granulate throw widths with a high degree of accuracy.
Normally, this work is carried out by hand, using shovels.
Consequently, achieving a large throw width is extremely
labour-intensive and exhausting. The GranuMatic makes
this work much easier. The heart of the machine comprises
a very efficient rotary blower which is driven by a diesel engine.
The flow of air generated by the blower conveys the
granulate to a rotary vane feeder and via a flexible hose
to a spreader tube. With this spreader tube, the granulate
can be scattered in measured quantities in a radius of up
to 12 meters.
The spreader tube allows the spreading path of the granulate
to be precisely controlled. Therefore, it is much easier
to ensure that an equal surface structure will be obtained.
The delivery capacity is approx. 50 to 75 kg/min, depending
on the specification of the granulate. For continuous
work, the material container must be topped up at regular
intervals. The capacity of the material container is approx.
200 liters and therefore it serves as a buffer and feed container
during the work operation.
