Embodiment 1

[0040] This embodiment discloses a method for crushing and separating fused magnesia, using such as Figure 1-7 The fused magnesia crushing and separating system includes a jaw crusher 1, a first hoist 3, a silo 2, a vibrating feeder, a vertical shaft impact crusher 4, a first cyclone separator 5, a linear vibrating screen 7, Second cyclone separator 10 and magnetic separator 12 .

[0041] Between the jaw crusher 1 and the vertical shaft impact crusher 4, a first hoist 3, a material bin 2 and a vibrating feeder are sequentially arranged. Specifically, the outlet of the jaw crusher 1 is set at the lower end of the first hoist track, and a silo matching the outlet of the loading crawler is set below the upper end of the first hoist track, and the silo The outlet is arranged above the vibrating feeder, and the outlet of the vibrating feeder communicates with the inlet of the vertical shaft impact crusher. The vibrating feeder can realize uniform feeding.

[0042] The outlet of...

Embodiment 2

[0054] This embodiment discloses a crushing and separating system for fused magnesia. A cyclone separator, the inner wall of the cyclone near the dust-laden air inlet of the cyclone separator is provided with a plurality of inserting plates along the circumference, and the inserting plates are inclined to the direction of wind flow. Compared with ordinary cyclone separators, which are difficult to separate due to piles of particles, the cyclone separator with insert plate in this embodiment can break up the piled particles, which is beneficial to separation.

Abstract

A fused magnesite crushing and separating method is disclosed. The method includes steps of adding a raw material into a jaw crusher, performing first time of crushing until the particle size of the raw material is 6-8 cm and the content of particles having a size of 40 meshes is 5-15%, feeding raw material particles after the first time of crushing into a vertical-shaft impact crusher, performing a second time of crushing until the particle size of the raw material is 4-6 cm and the content of particles having a size of 40 meshes is 40-60%, feeding raw material particles after the second time of crushing into a first cyclone separator, performing a first time of micro powder separation to separate particles the particle size of which is less than 400 meshes from the raw material particles, putting the raw material particles after the first time of micro powder separation to a linear vibrating screen to remove particles the size of which is less than 325 meshes, conveying the raw material particles residual on the screen to a second cyclone separator, performing a second time of micro powder separation, adding the raw material particles after the second time of micro powder separation to a magnetic separator, and performing magnetic separation to obtain a target product. The method is scientific and reasonable in steps, good in crushing and micro powder separation effects, and capable of effectively reducing the content of micro powder in the product.

Description

technical field [0001] The invention relates to crushing equipment technology, in particular to a method for crushing and separating fused magnesia. Background technique [0002] The existing fused magnesia pulverization method steps are unreasonable, resulting in excessively high fine powder content of crushed and separated products, which in turn leads to the following defects in fused magnesia products: high product flow rate, uneven density, large dust, and the size of the insulation behind the electric heating tube is not large. 1. The elongation rate of the electric heating tube is different. Therefore, there is an urgent need for a crushing and separation method for fused magnesia that can effectively reduce the content of fine powder under the premise of ensuring crushing efficiency and quality. Contents of the invention [0003] The object of the present invention is to propose a method for crushing and separating fused magnesia in view of the problem that the st...
