Description

Technical Field

[0001] The present invention relates to the technical field of processing raw materials for synthesizing ferric phosphate, and in particular to a raw material crushing device for synthesizing ferric phosphate. Background Art

[0002] In the preparation process of synthetic ferric phosphate, the crushing of raw materials is a key process step. The purpose of the crushing process is to refine the initial raw materials into the required particle size to meet the requirements of subsequent reactions. This process is especially important when it comes to using white fertilizer slag or ammonium phosphate slag as part of the raw materials. These slags usually contain under-utilized phosphorus components, which can be effectively recovered and reused through proper crushing and treatment.

[0003] In the process of crushing the raw materials for synthetic iron phosphate, namely white fertilizer slag and ammonium phosphate slag, a crusher is usually required. The existing crusher is usually composed of two sets of crushing rollers and filter plates. The rotation of the two sets of crushing rollers can achieve the purpose of crushing the raw materials for synthetic iron phosphate. At the same time, a filter is set at the bottom to screen the crushed raw materials to ensure that the crushed raw materials are of uniform size and improve the quality of subsequent processing.

[0004] However, in the process of filtering and crushing the raw materials through the filter plate in the crushing device, as time goes by, some raw materials with larger particles, such as raw materials extracted from white fertilizer slag and ammonium phosphate slag, will gradually accumulate on the top of the filter screen, causing the aperture of the filter screen to be blocked, affecting the subsequent raw materials from being filtered through the aperture. Therefore, the accumulation of raw materials on the filter screen not only affects the crushing processing efficiency, but also may reduce the effect of recovering iron phosphate from these slags.
