1, In order to match the ball mill drum feeder, we increase the sand scraper, thus it make the mortar from the side to the mill drum feeder.

2, Some classifiers using the rolling bearing to replace the original bearing bushing, so that reduce  the friction resistance and avoid the frequent replacement of bearing maintenance, by using ZQ type reducer to reduce installation and maintenance space.

3,Improved lubrication parts, large size products are equip with dry oil pump, with reliable lubrication.

1. When ordering, in addition to indicating the type and quantity, but also must indicate the direction of spiral classifier.

2. Associated with the ball mill for matching use, we can design according to user needs, we can make the lengthened type (back sand area lengthened, precipitation area lengthened), must  indicate extended dimensions.

3. The classifier is divided into several revolutions, when the user without special requirements, according to the conventional speed (In the table, black numerals with a short line) production.
