Turbine reaction composite vertical mill

Abstract

The invention relates to a turbine reaction composite vertical mill, which comprises a turbine disc, wherein a feeding pipe is arranged on the top of the turbine disc; a first bearing support is arranged outside the feeding pipe; the bottom of the turbine disc is connected with an output shaft of a driving motor directly or is provided with a second bearing support and is connected with the output shaft of the driving motor; the bottom of the turbine disc is connected with the output shaft of the driving motor directly by a lower end part with a middle shaft which extends downwards or is provided with the second bearing support and is connected with the output shaft of the driving motor; and a reaction disc is connected to the middle of the middle shaft. Two-stage crushing can be performed in the turbine reaction composite vertical mill, so under the condition of the same yield, the weight of equipment is only 3 / 5 that of 'a multi-stage turbine pulverizing mill', the height can be reduced by 1 / 2, the power matching is low, and power consumption can be reduced further, namely the power consumption of the vertical mill is between 5 and 6 kw h / t, and the power consumption of the multi-stage turbine pulverizing mill is more than or equal to 9 kw h / t; and the fineness of products can be higher, namely can be over 400 meshes, the pulverizing efficiency is improved greatly, the unit cost is lower, the investment can be saved, the centering and stability of a main shaft are ensured, and necessary conditions are provided for large-scale equipment.

Description

technical field [0001] The invention belongs to the technical field of material grinding machinery and equipment, and in particular relates to a turbine counterattack compound vertical mill. Background technique [0002] The structure of the existing vertical turbine pulverizer generally includes: a crushing chamber, and a motor located below is connected to the turbine above by its output shaft key. [0003] The material falls into the turbine from above and is centrifugally thrown by the blades of the turbine to the wall of the crushing chamber to be crushed. The turbine with this structure is connected to the cantilever output shaft of the motor, and because the materials received by the turbine cannot fall completely evenly, and the degree of wear of the turbine is different, the turbine is sometimes subject to a large eccentric force. The turbine connected to the cantilever shaft It will run unstable and shake left and right, and due to stability problems, it is diffi...

Problems solved by technology

The turbine with this structure is connected to the cantilever output shaft of the motor, and because the materials received by the turbine cannot fall completely evenly, and the degree of wear of the turbine is different, the turbine is sometimes subject to a large eccentric force. The turbine connected to the cantilever shaft It will run unstable and shake left and right, and due to stability problems, it is difficult to achieve stable operation and large-scale equipment
