海绵钛是精炼钛锭的原材料,它的表面凸凹不平外形很不规则,其内部组织密实度及其各部位的结构、孔隙率也都不同。生成后的直径一般都在1m以上(视坩锅直径大小而定),其硬度一般为HB115～185。为了精炼成钛锭,需把钛坨经过粗碎、中碎、细碎到一定粒度(0.5～30mm或0.5～12.7mm)。鉴于破碎粒度和质量对钛材质量有很大影响,因此,国内外对海绵钛的破碎工作十分重视,都在积极研制破碎新工艺及新设备。长期以来,我国海绵钛坨的破碎(包括近年来从日本引进的破碎机在内),都是采用整体钛坨压碎(以下简称“压碎”)的传统落后 Titanium sponge is the raw material of refined titanium ingot, its uneven surface is irregular, its internal organization density and the various parts of the structure, porosity are also different. Generated diameter are generally more than 1m (depending on the crucible diameter size), the hardness is generally HB115 ~ 185. In order to refine into titanium ingots, titanium lumps need to be coarsely crushed, broken, crushed to a certain size (0.5 ~ 30mm or 0.5 ~ 12.7mm). In view of crushing particle size and quality of titanium has a great impact on the quality, therefore, at home and abroad on the work of the sponge titanium broken very seriously, are actively developing broken new technology and new equipment. For a long time, the crushing of sponge titanium lumps in China (including crushers introduced from Japan in recent years) are based on the traditional backwardness of titanium lump crushing (hereinafter referred to as crushing)
