Problems solved by technology
[0007] The purpose of the present invention is to solve the problem that the grinding disc in the existing large-scale vertical mill is large in size, heavy in weight, difficult to manufacture, process, and transport. Once the grinding disc is damaged by cracks, it will directly cause damage to the main reducer, and to provide a large combined Disc Vertical Mill

The invention relates to cement building material machinery equipment, in particular to a large-scale vertical mill with combined mill disc, which comprises a machine frame, a mill disc device arranged in the machine frame and an air channel system, wherein a central shell and a mill roller pressurizing system are arranged above the machine frame; a separator is arranged above the central shell; the inside of the central shell is provided with a feeding system and provided with a power-driven system. The large-scale vertical mill with combined mill disc is characterized in that the upper and lower half parts of the mill discs in the mill disc device are connected through a flange and a bolt. The large-scale vertical mill with combined mill disc solves the problems that the volume of the mill disc in the prior large scale vertical mill is large, heavy, and difficult to manufacture, process and transport, particularly a speed reducer is damaged directly once the mill disc is cracked anddamaged. The large-scale vertical mill is mainly suitable to be used in raw materials, coal dust, cement and furnace slag powder milling systems in cement production.
Description
(1) Technical field: [0001] The invention relates to mechanical equipment for cement building materials, which is a vertical mill with large combined grinding discs. (two) background technology: [0002] Due to its advantages of high output, high grinding efficiency, and low energy consumption, vertical mills have gradually replaced ball mills and become the preferred equipment for raw meal and cement grinding systems in cement production. [0003] The development technology of vertical mills began at the beginning of the last century. In the 1980s, the development technology of vertical mills in my country began to develop gradually. Up to now, the development technologies of vertical mills at home and abroad have been relatively mature. Many vertical mill manufacturers have provided customers with various Types of vertical mills, the most famous of which are Loesche (Loesche) Loesche Mill, FLS (Smith Company) ATOX Mill, Pfeiffer (Pfeiffer Company) MPS Mill, Polysius Company...
