1.Low noise
2.Low energy consumption
3.Quick control response
4.The vibration is small from start to stop
5.Strong adaptability
6.Small covering area
7.Easy adjustment
8.Excellent dry grinding capacity
9.Easy maintenance (no need to dismantle and can replace easily worn-out parts)
Vertical roller mill (known as vertical mill) has the features of good process performance and low energy consumption. The comminution technique trends to its development. This mill grinds the particles in a limited bed in principle of a particle bed comminution to improve the energy availability and reduce the energy consumption by 30% or so. In the integration with the high efficient separator of the third generation it improves the separation efficiency considerably, enhances the output in the system and optimizes the product size distribution. The mill suns in a negative chamber plus a compact intermediate to prevent the dust escape from the system in order to achieve a environment-friendly operation. This type of mill is a large heavy technical equipment that is energy-saving and environment-friendly. It is introduced and applied widely in China.

LGMS vertical roller mill for slag and LGM vertical roller mill for cement raw meal are both the large grinding complex in an integration of crushing, grinding, separating, drying, and conveying. The machine has the features of the concentrated process, less space, low cost, energy saving and reduced power consumption. After the Chinese first large slag vertical mill LGMS4624 with CITIC HIC's own design and manufacture has been put into production successfully in Jiangsu Leida, it has become the main model on slag grinding production line, and CITIC HIC has succeeded in developing the largest slag mill Lgms5725 in China. CITIC HIC's own large raw material vertical mill LGM5024 has been put into production successfully in Jilin Yatai Group, Neimeng Mengxi Group and Kungang Jiahua Cement Group. Based on this, CITIC HIC has developed the larger raw material vertical mill LGM5426.
Application:
The mill is mainly applied in grinding cement raw meal and clinker in construction material processing and grinding blast furnace slag in the metallurgical industry.
Technical Features:
Grinding table.
There is a certain inclination between the conical roller and grinding table.
Swing crank arm responsible for fixing and guiding the table is outside the mill shell.
Feature:
Vertical roller mill for slag: Roller is designed in 2+2 and 3+3 which is more suitable for milling the clinker and the slag. The main roller and the assist roller are arranged symmetrically. The assist roller compacts the bed and the air is let out in the gap between particle before the main roller grinds in the stable particle bed to absorb the possible vibration.
Vertical roller mill for raw meal: Four independent rollers design, Equal load on grinding table, High efficiency for grinding all type of raw material, High capacity.
The hydraulic-pneumatic combined spring loading system compresses stably to provide a function of a elastic buffer.
Limit buffer is designed to make it possible that there is no metal contact between the roller parts in full mill operation.
The course particle separator (separator ) is an integrated part of the mill. The stator blade can be adjusted.
The roller extraction device driven hydraulically ensures a simple and quick maintenance and replacement.
The grinding table can be adjusted in height to retaining particles for different wearable materials and parameter changes in the system.
The position of roller is monitored in real-time by a displacement sensor to adjust the operating parament in time.
The design of grinding table part,reducer part and foundation functions for damp shock.
Common features of vertical roller mill:
Simple operation and sensitive response;
High drying capacity to allow the water content in feed to be 20%;
An integration of drying, milling, gas conveying and course particle separation:
High throughput;
Low specific energy consumption.
Less vibration and less noise;
Compact structure, easy arrangement, civil cost savings.
MZL Reducer on LGMS\LGM Vertical roller Mill:
Various kinds of different reducers are developed to meet the requirement in cement industry. They form a series of reducer product with transmission power 2800-6400 kw used on vertical roller mill. The reducer can be installed on the vertical mill in complete. The company got a medal for the large reducer "China Top Brand" in 2007.
