Ash hopper skirt type aggregate discharge device of vertical roller mill

Abstract

The invention discloses an ash hopper skirt type aggregate discharge device of a vertical roller mill. The device comprises a mill shell, an ash hopper used for collecting waste, an abrasive disk used for mashing the waste, and an ash hopper discharge tube used for leading the waste in the ash hopper onto the abrasive disk. A material collecting hopper used for collecting powder and discharging the powder in a guiding mode is arranged under the ash hopper. A pore or net structure is arranged on the portion, arranged in the material collecting hopper, of the ash hopper. The lower end of the material collecting hopper is connected with a pipeline. The lower end of the pipeline is connected with an external discharge tube. According to the ash hopper skirt type aggregate discharge device of the vertical roller mill, by designing the special skirt type material collecting hopper at the joint of the ash hopper cone bottom and the ash hopper discharge tube, materials in the area near the material collecting hopper are collected and discharged out of the mill through the pipeline to form a product. The ash hopper skirt type aggregate discharge device of the vertical roller mill has the significance that the conventional function that a vertical mill can only produce one type of products within a certain time is changed, the vertical mill can be used for producing products with two particle diameter requirements, new functions of the vertical mill are developed, and application and popularization of the ash hopper skirt type aggregate discharge device of the vertical roller mill in a wider range of fields are facilitated.

Description

technical field [0001] The invention belongs to the technical field of construction waste treatment equipment, and in particular relates to a vertical ash hopper skirt type aggregate discharge device. Background technique [0002] Vertical mill equipment is a new technology integrating grinding, homogenization, drying, powder selection and conveying functions. Its wide application, economy and stability have been proved by industrial practice. The adaptability and energy-saving characteristics of the vertical mill conform to the development of many industries. Although the vertical mill has been developed for nearly a hundred years, there has been no major breakthrough in structure and principle, so it is only characterized as a milling equipment to a large extent. , Other application properties of the vertical mill have not been expanded. [0003] With the development of economy and technology, industrial waste such as construction waste (waste concrete blocks, waste brick...
