hello:

We are designing a vibrating screen to separate dry ashes from gasification process.

It´s a little equipment for 20kg of ash per hour.

The size of the ashes is less than 50mm and bigger than 0.5mm. We want to separate in 10mm.

We want to use an unbalanced motor (n=3000rpm and F=800N).

The size of the screen is about 200mm (wide)x300mm (long).

The mass of the vibrating part is around 30kg.

The equipment is sealing from de outside and is developed in 150ºC reducing atmosphere.

We have bought the VSMA handbook and we can find some rules to calculate the slope,the size of the screen, the size of the holes. But nothing about the size, stiffness or position of the springs. We would like to know any book, article, reference, help or similar about this. Could somebody help us?.

Thanks in advance.

Best regards
