Description

Technical Field

[0001] The utility model relates to the technical field of fused magnesia production, and more specifically to a fused magnesia crushing and separation device. Background Art

[0002] Fused magnesia is a general term for the products of magnesia raw materials such as magnesia that have been sintered after high-temperature treatment to reach the degree of sintering. The magnesia fired with natural magnesia as raw material by a single calcination or two-step calcination process using high-temperature equipment such as vertical kilns and rotary kilns is called sintered magnesia; the magnesia formed by smelting magnesia and other raw materials in an electric arc furnace to a molten state and then cooling is called fused magnesia; the magnesia made from magnesium oxide extracted from seawater is called seawater magnesia, and fused magnesia needs to be screened and separated during its production process.

[0003] After searching, the utility model patent with announcement number CN220215099U discloses an efficient screening device for crushing and separating fused magnesia, including a crushing component and a screening component, the bottom of the crushing component is fixedly connected to the top of the screening component, the crushing component includes a crushing box, the bottom of the crushing box is fixedly connected to the top of the screening component, and the top of the crushing box is fixedly plugged with a feed trough; the patent fills the water tank with water, and then puts the fused magnesia from the feed trough into the crushing box, and starts the water pump and the drive motor at the same time. The drive motor drives the driving gear to rotate in the crushing box, so that the driven gear is forced to rotate synchronously. At this time, the two crushing rods rotate synchronously to crush the incoming fused magnesia, and the fused magnesia can be crushed more thoroughly by mincing. During the crushing process, the water pump draws out the water in the water tank and discharges it through an inclined nozzle.

[0004] However, the above patent still has the following shortcomings: the crushed fused magnesia is discharged from the crushing box through an inclined filter screen. When a large amount of crushed fused magnesia falls on the filter screen, some of the fused magnesia will easily stay on the filter screen, affecting the discharge speed of the fused magnesia; and the surface of the fused magnesia is cleaned by spraying water, so that the fused magnesia after crushing and separation is stained with water, and it is necessary to wait for the water on the fused magnesia to be dried, which affects the subsequent treatment of the crushed fused magnesia. For this reason, we propose a fused magnesia crushing and separation device. Utility Model Content
