Abstract

The invention relates to a weakly magnetic mineral powder preheating treatment and reduction system. The system comprises a crushing and drying device, a preheating device, an accumulation reduction device and a cooling device, wherein the crushing and drying device is used for treating weakly magnetic mineral powder until the weakly magnetic mineral powder with a preset fineness of -0.074 mm accounts for more than 30% and the water content is less than 3%; the preheating device is used for preheating the weakly magnetic mineral powder treated by the crushing and drying device; the accumulation reduction device is communicated with the preheating device and is used for conducting reducing treatment on the preheated high-temperature mineral powder; the accumulation reduction device comprises at least two reduction bins, and the reduction bins are provided with coal injection devices used for injecting coal into the reduction bins for reduction treatment; and the cooling device is used for cooling the ore subjected to reduction treatment in a water cooling manner, so that the cooled ore pulp is conveniently conveyed to a mineral separation system. The preheated weakly magnetic mineral powder is reduced through at least two reduction bins, so that the problems that an existing magnetic roasting mode is complex in control process and high in energy consumption are solved.

Description

technical field [0001] The invention belongs to the field of mineral processing equipment, in particular to a weak magnetic mineral powder preheating reduction system and an electronic device. Background technique [0002] There are a large amount of red (brown) iron ore and other weakly magnetic ore powders at home and abroad, which cannot be processed by conventional beneficiation. It needs magnetization roasting and then magnetic separation to obtain high-grade iron concentrate. Common magnetization roasting methods at home and abroad include shaft furnace roasting, rotary kiln roasting, suspension roasting, etc., which have disadvantages such as complicated control process, high energy consumption, and serious pollution. Based on the above problems, the inventor proposed the present application. Contents of the invention [0003] In order to solve the above-mentioned problems, the present application provides a kind of mineral processing equipment, aiming at at least ...
