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.
