Powder grinder for strontium carbonate processing

Abstract

The invention relates to the technical field of grinding devices, in particular to a powder grinder for strontium carbonate processing. The powder grinder comprises a grinding device feeding frame, afeeding port is formed in the top end of the grinding device feeding frame, a discharging frame is arranged at the bottom end of the grinding device feeding frame, and a reinforcing rib plate is additionally arranged between the discharging frame and the grinding device feeding frame; a driving shaft penetrates through the surface of the grinding device feeding frame, a plurality of material stirring plates are arranged on the surface of the driving shaft, and a telescopic groove is formed in the surface of the material stirring plate. The powder grinder for strontium carbonate processing hasbeneficial effects that the powder grinding device for strontium carbonate processing is additionally provided with the grinding device feeding frame, the driving shaft is additionally arranged in thegrinding device feeding frame for mounting material stirring plates, a plurality of charging spaces are formed by the plurality of material stirring plates, quantitative feeding of the discharging frame is achieved, a series of troubles caused by one-time continuous feeding are avoided, and a telescopic structure is additionally arranged at the end part of the material stirring plate to pull a cleaning plate to clean residual materials on the inner wall of the grinding device feeding frame.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a powder grinder for processing strontium carbonate. Background technique [0002] The lapis lazuli and coal powder are pulverized to pass through 20 meshes as raw materials, the ore-to-coal ratio is 1:0.6~1:0.7, and the reduction roasting is carried out at a temperature of 1100~1200°C. After 0.5~1.0 h, the roasted product is leached twice. , wash once with water, leaching temperature 90℃, leaching for 3 hours each time, the total leaching rate can reach more than 82%, the leaching solution is filtered, and the filter residue is leached with hydrochloric acid to further recover strontium. Ammonium bicarbonate or sodium carbonate solution is reacted to form strontium carbonate precipitate (or directly carbonized with carbon dioxide), and then separated, dried, and ball milled to obtain the finished product of strontium carbonate.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when raw materials are pulverized, one-time input of materials easily leads to incomplete pulverization, and there is a risk of crushing roller jamming; therefore, the present invention proposes a powder grinder for strontium carbonate processing to solve the above problems
