Introduction

LM vertical roller mill is a kind of high efficiency and energy saving product perfectly combined with 30 years of mature vertical grinding technology, foreign successful experience and our company's technical innovation and upgrading. It has realized the localization of world-class vertical grinding.

It adheres to advanced powder making technology and multi-function, adopts reasonable and reliable structural design, and coordinates with advanced technological process. Its main technical and economic indicators reach the international advanced level.

After decelerating by the gear reducer which installed at upper main engine. Material that scooped up the blade is grinded between roller and ring, and then the grinded powder is blown into analyzer by air blower for separation. After being classified by cage classifier, substandard material fall back for regrinding, and standard powder is blew into bypass cyclone collector.
product introduction

Product Advantages

  • 01

    Optimized Grinding Device

    • The Grinding Mill adopts the heavy type design which fully considers the grinding efficiency and service life and has achieved many key breakthrough.

  • 02

    The stability of product quality

    • As the material stays in the mill for a short time it is easy to detect and control the product particle size and chemical composition to reduce duplication of grinding stabilize product quality.

  • 03

    High Chrome Hammer Plate

    • Keyless connection easy to maintain high abrasion resistance big impact. Unique plate hammer fixation device makes maintain and disassembly easier.

  • 04

    Low Investment Cost

    • This mill itself can crush dry grind classify and transport so the system is simple and occupation area is about 50% of ball mill system. In addition it can be installed outside so it will reduce a large number of investment costs.
