Title: Method of screening materials
Inventor: KRYVORUCHKO OLEKSANDR MYKHAILO
IPC: B07B1/00
Filed: 2003-04-29
Abstract: A method of screening materials includes supply of material into the vertical channel, in which vibro-excited grates are installed one under another in zigzag manner. The grates are located in two vertical sections, in which forced dynamic effect is achieved. The process of screening is achieved due to the joint kinetic energy of the flow of material, energy of forced oscillations of grates and energy of vibroexcitation of grates. Forced dynamic action is carried out separately in each section with different fixed vibration frequency: resonance frequency and frequency larger than resonance frequency. The invention ensures the improvement of the quality of screening of moist fine-fraction materials and output of the process of screening.
