Coarseness and fineness integrated iron ore hydraulic pulverizer

Abstract

The invention provides a coarseness and fineness integrated iron ore hydraulic pulverizer. The coarseness and fineness integrated iron ore hydraulic pulverizer is provided with an upper coarse pulverizing chamber and a lower fine grinding pulverizing chamber. The discharge port end on the bottom of the coarse pulverizing chamber communicates with the fine grinding pulverizing chamber through a discharge channel. The fine grinding pulverizing chamber is internally provided with an upper pressure cylinder, a lower pressure cylinder, an upper pressing plate, a lower pressing plate, a grinding rotary table and a grinding motor. The upper pressing plate is an annular pressing plate, the inner edge of the upper pressing plate is matched with the outer wall of the discharge channel, and the outer edge of the upper pressing plate and the outer edge of the lower pressing plate are matched with the inner wall of the fine grinding pulverizing chamber. At least one side of the fine grinding pulverizing chamber is provided with a discharge door. The upper pressure cylinder is installed between the upper side wall of the fine grinding pulverizing chamber and the upper pressing plate, and the lower pressure cylinder is installed between the lower side wall of the fine grinding pulverizing chamber and the lower pressing plate. The grinding motor is installed on the lower pressing plate, an output shaft of the grinding motor penetrates the lower pressing plate to be fixedly connected with the grinding rotary table, and grinding teeth are arranged on the lower surface of the upper pressing plate and the upper surface of the grinding rotary table in a staggered manner. The coarseness and fineness integrated iron ore hydraulic pulverizer is simple in structure and can achieve coarseness and fineness integrated pulverizing conveniently to meet machining requirements of iron ore produces with different grain size grades.

Description

technical field [0001] The invention relates to an iron ore crushing device, in particular to a thick and fine integrated iron ore hydraulic crushing machine. Background technique [0002] The crushing of ore refers to the process of crushing the material ore by mechanical means, so that the larger stones become relatively smaller stones or even ore powder. At present, there are many types of ore crushers on the market, and their working principles are also different, such as jaw crushers, cam crushers and so on. But they all have a common shortcoming that they cannot effectively control the gap between the crushing actuators, and the crushing of ore is not uniform and thorough enough. For some enterprises that need powder grade ore powder grade, most of the existing equipment in the market If the requirements cannot be met, it is often necessary to repeatedly crush an ore, which complicates the processing technology, prolongs the processing time, and reduces work efficienc...
