description
It is used for shot blasting of flat steels of different dimensions and lengths of large series. (For example: flat steel 9 x 12 mm, 20 x 30 mm, 25 x 24 mm). It is suitable for medium capacity. It depends on the construction of the machine and required speed flow of work pieces (usually between 3 – 12 m / min). Transport type: The machine is equipped with a horizontal manipulator for automated handling of flat steel to machine and then on conoid rollers through shot blasting machine.
Shot blasting machine type PL 20x30 is used to shot blast flat steels of maximal dimensions 20 x 30 mm and minimal dimensions 12 x 8 mm. Orientation of flat steel can be vertical or horizontal. Working speed is 6 m / min, quality of cleaned surface is minimal Sa 2 ½.
Flat steel is loaded to a loading device. Vertical conveyor is adding flat steel on roller conveyor automatically, pressing wheel is pressing flat steel on the rollers. After shot blasting they are automatically unloaded from roller conveyor. Width of guiding beam on roller conveyor can be changed according to a width of flat steel. In the machine there are two change-over flaps from wear- resistant steel, which direct jet to working pieces, in way that the throwing wheel energy is maximal used. Entrance switch automatically turns on – off shot blasting, so that throwing wheels shot blast only on working piece, this decrease wearing of the machine and use of energy to minimum. Additional dust collector on exit of fan allows release of air into working space in mode, that in winter time there is no loss of heat. Machine is robust; shot blasting part is made of manganese steel and additionally protected with wear – resistant shields.
