VM - Vertical Grinding Mill

VM series vertical grinding mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of research of mills, vertical grinding mill is designed and manufactured based on advanced home and abroad technology, in combination with years of experience in the production of grinding machine and the market demand. VM vertical grinding mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meet the requirement of clients of the high production of powder, and its main technical and economic indicator reaches the international level.

Vertical grinding mill is the ideal substitute of the traditional grinding mills like raymond mills, high pressure suspension grinding mills, ball mills, etc. Nowadays, Kefid vertical grinding mills have been widely used in cement, power,metallurgy, chemical and nonmetalliferous ore industries. The vertical grinding mill is widely used to grind lumpy, granular and powdery material to the required size. It can grind the non-flammable and non-explosive mineral materials with Moh's hardness less then scale 9.5 such as quartz, feldspar, calcite, talcum, barite, fluorite, marble, iron ore, manganese ore, zircon, slag, chrome green, gold mine, kaolin, gangue, pyrophyllite, red ware rock, basalt, gypsum.

Maintenance Of Vertical Grinding Mill

Maintenance is very important for vertical grinding mill, and is related to life. The operator must note these things as follows:

1. Normally plan 2 days per month or every other week
2. Mill internal inspection; monitor wear
3. Feed belt systems, dust collectors
4. Scale calibrations
5. Inspect/clean water spray lances

1. Normal Table and Grinding Roller segments
2. Lower separator cone
3. Scatter ring – Check underside as well!
4. Mill inlet plenum – check for buildup
5. Reject or plow chamber
6. Process Fan, inlet cones, dampers

Technical Parameter

Mm to inch conversion: 25.4millimeters=1 inch
Mm to mesh conversion: 25.4mm=1in.
The humidity and hardness of raw materail will affect the fineness and capacity.
