Problems solved by technology

[0002] In the coarse and fine ore separation process; most of the machines used in the dry coarse and fine ore separation currently use vibrating screening machines. The vibrating screening machine has the advantages of strong practicability and reliable screening effect, but there is a consumption The energy is high, the noise is high, and the dust raised by the ore powder carried by the ore particles during vibration is very polluting to the environment, and has caused harm to the health of the operators. , energy-saving, and no pollution to the environment of the birth of the ore separator

Abstract

The invention relates to crude and fine ore grain separation in the processes of grinding, rolling, ball-milling, crude and fine ore grain separation and the like of raw ores in a mineral separation process. The following two separation forms exist in the crude and fine ore grain separation process: wet separation and dry separation. The invention provides a negative pressure cyclone ore grain screening machine, namely a dry totally closed negative pressure environment-friendly and energy-saving machine used for crude and fine ore grain separation.

Description

Technical field: [0001] The present invention relates to the separation of coarse and fine ore particles from the raw ore in the mineral processing process: crushing, rolling, ball milling, coarse and fine ore separation, etc. There are two types of separation in the coarse and fine ore separation process Form; 1. It is wet sorting. 2. It is dry sorting. What is going to be described here is a kind of dry-type fully enclosed negative pressure environmental protection and energy-saving machine for sorting coarse and fine ore particles--negative pressure cyclone ore particle screening machine. Background of the invention: [0002] In the coarse and fine ore separation process; most of the machines used in the dry coarse and fine ore separation currently use vibrating screening machines. The vibrating screening machine has the advantages of strong practicability and reliable screening effect, but there is a consumption The energy is high, the noise is high, and the dust raise...
