Adaptive energy-gathering vertical roller mill

Abstract

The high-efficiency vertical roller mill includes a hydraulic transmission system, an intelligent control system, a frame (1), a transmission device (2), and a reduction mechanism (6). (8) Installed on the outer circle of the grinding disc device (15) and at the upper opening of the air inlet duct (7) connected to the air inlet pipe (5), multiple grinding roller devices (10) pass through the lower casing (11) The grinding door is installed above the grinding disc device (15), and the rocker arm (9) is installed on the outer end of the grinding roller device (10). ) connection, the other end is connected with the frame (1) respectively, and the powder selection device (12) is installed on the upper end of the middle casing (14). The machine has the advantages of efficient use of extrusion energy and impact energy, reducing the vibration intensity of the grinding host equipment, improving grinding efficiency, reducing grinding energy consumption, improving equipment stability and service life, and reducing operating costs.

Description

technical field [0001] The self-adaptive vibration-gathering and energy-supplying vertical roller mill belongs to grinding equipment in mining, electric power, building materials and cement industries, and specifically relates to a vertical roller mill. Background technique [0002] Compared with the ball mill, the vertical roller mill has high grinding efficiency, low energy consumption, compact structure, convenient process layout, simple process flow, small floor space, large drying capacity, and large particle size of the material to be milled. The advantages of strong adaptability to grinding materials, no dust leakage in negative pressure operation, and low noise have attracted more and more attention from domestic and foreign mines, electric power, building materials, and cement industries. However, since the vertical roller mill is the main equipment in the application of various industries, its grinding operation process is an important link and has the characterist...

Problems solved by technology

However, since the vertical roller mill is the main equipment in the application of various industries, its grinding operation process is an important link and has the characteristics of large lag, nonlinearity, strong coupling, etc., so it has always been vertical The key and difficult issues in the grinding operation process control of roller mills not only put forward higher requirements for the grinding process control technology, but also put forward higher requirements for the structural design and optimization of vertical roller mills. Requirements; application practice proves that the vertical roller mill is sensitive to the stability of the powder-abrasive bed and the vibration of the equipment itself. A large number of cases show that the instability of the powder-abrasive bed and the vibration of the vertical roller mill are likely to cause equipment failure. And it is difficult to control timely and safely; what’s more, the particle shape and gradation of the finished powder cannot be effectively controlled by the powder selection device of the vertical roller mill. The above problems need to be solved in the development process of the vertical roller mill. Troubleshooting
