INTRODUCTION

LM series vertical roller mills are a excellent grinding equipment, which have the capacity of 24hours constant running. Because of this automatic operation, this VRMs are popular in the condition, which needs easy monitor, large capaity, constant running, stable product quality, like large mineral powder plant, cement plant, GGBS powder plant, coal grinding plant, etc.

PRODUCT ADVANTAGES

High Purity of Material

LM Vertical Grinding Mill can effectively control product size, chemical composition and iron content, and ensure the purity and whiteness of finished materials.

Less Comprehensive Investment

LM Vertical Grinding Mill adopts a compact integrated design, which covers an area of about 50% of the ball mill system, and can be arranged in the open air with less comprehensive investment.

High Degree of Automation

LM Vertical Grinding Mill is equipped with an automatic control system, which can realize free switching between remote control and local control. It is easy to operate and has low labor cost.

Environmentally Friendly

LM Vertical Grinding Mill is sealed and operates under negative pressure, characterized by no dust spillover, small vibration, low noise, and more eco-friendly production.

FAQ

Can the dust emissions from the LM vertical mill meet the standards?

Certainly. The LM vertical mill is designed to operate under complete negative pressure, and it’s equipped with a pulse dust removal system. The dust emission concentration is less than 30mg/m³, meeting national environmental protection standards.
Is the particle size distribution of the product made by the LM vertical mill uniform?

The distribution is extremely uniform. The LM vertical mill uses a cage-type powder separator, enabling precise particle sizing. As a result, the finished product has a narrow particle size distribution, good particle shape, and stable quality.
What’s the level of automation in LM vertical mills?

The LM vertical mill features a fully automated control system. It enables one-key start/stop, automatic load adjustment, and automatic fault alerts. No manual supervision is required on-site, significantly reducing labor costs.
What are the vulnerable parts of the LM vertical mill? What is the replacement cycle?

The main vulnerable components include the grinding roller sleeves, grinding disc linings, and classifier blades. Under normal operating conditions, the replacement cycle for roller sleeves and linings is 1–2 years, depending on the hardness of the material and the level of usage.
Can the LM vertical mill process materials with high moisture content?

Certainly. The LM vertical mill is equipped with a built-in hot air drying system. The temperature of the hot air can be adjusted to dry the material accordingly. It can handle materials with a moisture content of up to 15%, eliminating the need for pre-drying equipment.
What is the maximum fineness of the product that can be achieved with an LM vertical mill?

The fineness of the product produced by the LM vertical mill can be adjusted arbitrarily between 80-600mesh. Precise control of the fineness is achieved through a variable-frequency powder separator.
