Description: The rubber bouncing ball (screen cleaning ball) of the vibrating screen is a wear-prone accessory for corn linear cleaning vibrating screens and is placed between the screen frame and the perforated support mesh. Relying on the vibration of the equipment, it continuously bounces up and down and repeatedly strikes the screen mesh to shake off broken corn, corn husks, dust and fine moldy particles stuck in the screen holes. It prevents the screen mesh from clogging and continuously ensures the screening throughput and impurity removal effect, making it an essential self-cleaning accessory for corn raw material pretreatment production lines.
Principle After the vibrating screen is started the bouncing balls bounce back and forth at high frequency in the mesh frame cavity.
Continuously impacting the upper screen mesh clearing blockages in the mesh holes and stop material from sticking to the mesh.
At the same time it helps to loosen corn material and improve the separation efficiency of whole corn kernels from broken kernels and impurities.
Mainstream Material Classification (Material Selection for Corn Processing Conditions)
1. Natural Rubber Bouncing Ball (Black).
Cost-effective, with strong rebound force and impact resistance. Corn coarse screening at grain depot purchasing stations and feed mills, and screening of dried corn raw materials.
Drawbacks: Prone to aging after long-term use under humid and high-temperature conditions. Food-grade Silicone Bouncing Ball (White/Semi-transparent) [Preferred Choice for Corn Starch and Bio-fermentation Projects].
Non-toxic and odorless does not contaminate grain high temperature resistant not easy to stick to materials antioxidant and with a longer service life.
Edible corn corn starch plants alcohol plants deep processing EPC production lines and processes with food hygiene requirements.
Specifications for Corn Screening Mainstream diameters: Φ20mm, Φ25mm, Φ28mm and Φ30mm; the most commonly used for grain linear impurity removal screens are Φ25mm and Φ28mm.
Selection principle: The ball diameter must be larger than the screen aperture to stop the bouncing ball from falling through the mesh holes.
Product 1. The ball is smooth and round with low out-of-roundness, providing stable rebound and uniform impact.
2. High elasticity, wear resistance and fatigue resistance; it is not easy to crack under long-term high-frequency vibration.
3. The food-grade silicone material meets the hygiene standards for grain and oil processing, with no impurities falling off.
4. Installation is simple: the balls are directly placed in the compartments of the screen frame without additional fixing.
5. It effectively solves the problem of screen clogging caused by broken corn and bran powder and reduces the frequency of downtime for cleaning.
