Application
Rubber balls for vibrating sieves help improve screening performance by preventing the accumulation of screened material that can cause blockages in the sieve screen openings. How do they work? Vibrations produced by the plant motor are transferred to the screen mesh, causing the rubber balls to bounce and clean the accumulated material from the screen openings.
Types
Rubber ball cleaners are mainly made from standard EPDM rubber, highly elastic natural NR rubber, and silicone rubber:
Silicone rubber cleaners: Characterized by standard elasticity, good resistance to acids, alkalis, oils, and lubricants, and good resistance to low and high temperatures.
EPDM synthetic rubber cleaners: Characterized by standard elasticity, good resistance to acids, alkalis, ozone, and atmospheric influences, but low resistance to oils and lubricants (resistant to vegetable oils).
Natural NR rubber cleaners: Characterized by excellent elasticity, good resistance to acids and alkalis, but low resistance to oils and lubricants.
Technical Specifications
Available in sizes of 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, and 50 mm.
Recommendations for Choosing Rubber Ball Size:
- For rotary vibrating sieves with a diameter less than 800 mm, a rubber ball diameter of 20 mm is usually recommended.
- For screens with a diameter from 1 m to 2.5 m, rubber ball cleaners with diameters of 25 mm and 28 mm are usually recommended.
- For screens larger than 2.5 m in diameter, rubber ball cleaners with diameters of 30–40 mm are usually recommended.
