1. Slotted type screen basket is produced by making a slot-shaped hole using catter on the plate and
   widely used. Careful selection effect of raw materials increases to the full because slot type becomes
   perpendicular to the direction of rotor's rotation movement.

2. Although slot type can improve careful selection degree of raw materials by removing smaller granular
   alien substances compared with hole type, its capacity is lower than hole type and long substances are
   not hardly removed.
   Currently various profile-shaped baskets are being produced and profile- shaped baskets are very
   effective in processing large quantity by generating whirlpool movement of a fluid when processing
   raw materials.

3. Usually, 0.15m/m ~ 0.45m/m slots are used.
