The traditional roller sieve, due to restrictions, each structure between rollers cannot adjust, using a gear transmission, when the screen roller use after a period of time, the interval between screen roll become larger, qualified raw ball plenty of leakage, caused the roller sieve efficiency is lower. Each pelletizing plant (sintering plant) often take the change of roller diameter larger part roller adjusted so that again, also increased cost increases the repair work, LGS roller clearance adjustable round roll sieve used single roller drive, effectively solved the problem which can adjust each roller clearance, and do not suffer roller number accumulated adjustment quantity caused by big effect to the maximum use screen roller Specificationroller and lengthscreen roller materialsSift roller quantityLGS1000×Φ102Lightweight compositeLGS1020×Φ102Lightweight composite26LGS1040×Φ102Lightweight compositeLGS1050×Φ102Lightweight compositeLGS1070×Φ102Lightweight composite25LGS1150×Φ102Lightweight compositeLGS1200×Φ102Lightweight composite26LGS1200×Φ105Lightweight compositeLGS1380×Φ105Lightweight compositeLGS1380×Φ125Lightweight compositeLGS1400×Φ102Lightweight composite27LGS1450×Φ102Lightweight composite27LGS1550×Φ95Lightweight compositeLGS1550×Φ102Lightweight compositeLGS3136×Φ115Lightweight compositeLGS3136×Φ133Lightweight compositeLGS3155×Φ119Lightweight compositeLGS3980×Φ125Lightweight compositeLGS3980×Φ130Lightweight compositeLGS4000×Φ130Lightweight composite23LGS4152×Φ130Lightweight compositeLGS4750×Φ140Lightweight composite26
