一、浙江凝灰?guī)r特性與破碎加工難點
作為典型的火山碎屑巖，浙江地區(qū)凝灰?guī)r具有以下特征：
硬度特性：莫氏硬度3-5級，屬于中等硬度巖石
結(jié)構(gòu)特點：孔隙率較高（10-15%），局部含硅質(zhì)夾層
加工難點：
破碎過程中易產(chǎn)生過多粉末（石粉含量控制）
大塊原料占比高（最大進(jìn)料達(dá)800mm）
成品粒形要求嚴(yán)苛
針對上述特點，世邦工業(yè)科技集團(tuán)特別開發(fā)了浙江凝灰?guī)r專用破碎機(jī)解決方案。

智能運(yùn)維：
關(guān)鍵部位實時監(jiān)測（振動、溫度、電流等）
五、結(jié)語
該條時產(chǎn)300噸凝灰?guī)r破碎生產(chǎn)線作為世邦工業(yè)科技在華東地區(qū)的標(biāo)桿項目，成功解決了浙江凝灰?guī)r加工的三大行業(yè)難題：
大塊率過高的問題（通過PEW860強(qiáng)力破碎）
粒形達(dá)標(biāo)率提升（HPT500層壓破碎）
項目投產(chǎn)以來，其"好的破碎+智能控制+綠色生產(chǎn)"的模式正在浙江地區(qū)推廣應(yīng)用。
