Working principle of german loesche vertical mill energy storage device

How does a Loesche roller grinding mill work?

The grinding material is comminuted in the Loesche roller grinding mill between the rotating horizontal grinding track and the stationary grinding rollers. Grinding is effected primarily by compression. A certain amount of shear force increases the quantity of fine particles in the grinding material.

How does a Loesche mill work?

The Loesche mill is filled via a star feeder, which pre-vents air leakage into the grinding chamber. The grinding material flows continuously from the top via the inlet hopper into the pockets of the slowly rotating star wheel. Wear caused by the abrasive feed material is minimized by the low circumferential speed.

What is a Loesche grinding plant?

The core elements of these plants are the Loesche vertical mills for dry-grinding the above-mentioned grinding stock. Loesche has developed and built the largest and most efficient grinding plants for its customers. Loesche plants are specifically planned for the required process steps and equipped with the associated techno logy.

Is the Loesche vertical-roller-mill a serious alternative to conventional grinding technologies?

The paper demonstrates why the Loesche Vertical-Roller-Mill (VRM) is a serious alternative to conventional grinding technologies and where the limitations of the system are. VRM's are state of the art technology in the cement, steel, power and minerals industry.

What is the power consumption of Loesche ball mill system?

Ball mill system Loesche Power consumption VRM system 20 40 60 80 100 120 140 160 Fineness acc. to Blaine 3 000 4 000 5 000 6 000.

Does a Loesche VRM reduce s pecific grinding media consumption?

The pilot test work indicates a reduction of the s pecific grinding media consumption of 95% when operating a VRM using metal matrix composite grinding elements. liberation could be significantly improved by grinding with the Loesche VRM.
