2. Professional designed stock guide , adjustable long overflow weir board and optimized spiral speed make washing and classification to be more accurate.
3. New leakproof structure can reduce the maintenance work and upkeep cost to the maximum content. 
4. The helical blade is made of wear-resistant material , this can reduce the cost and make the machine have a longer service life.
