DH-800-4S all stinless steel vibration sieve is mainly used in the food industry, pharmaceutical industry, chemical industry. GMP production require enterprises should have good production equipment, such as food, pharmaceutical industry require whole machine is 304 or 316 stainless steel material vibration sieve. DH-800-4S all stinless steel vibration sieve work principle Vibrating screen is vertical vibration motor as vibration source, upper and lower of vibrating motor installed eccentrcs, then changing rotation movement into horizontal, vertical, inclined Three-D movement, finally, conveying the movement to sieve surface. Adjusting upper and lowe angle to change material movement direction on the screen.
