具有破碎比大、產(chǎn)品粒度均勻、結(jié)構(gòu)簡單、工作可靠、維修簡便、運營費用經(jīng)濟等特點。工作原理工作時，電動機通過皮帶輪帶動偏心軸旋轉(zhuǎn)，使動顎周期地靠近離開定顎，從而對物料有擠壓搓碾等多重破碎，使物料由大變小，逐漸下落，直至從排料口排出。隨著電動機連續(xù)轉(zhuǎn)動而碎石機動顎作周期運動壓碎和排泄物料，實現(xiàn)批量生產(chǎn)。缺點是雞舍的建筑通風設(shè)備清糞設(shè)備要求較高，不便于觀察雞群，管理困難。
鉀長石是分布最廣和蘊藏量最豐富的含鉀礦物，在我國各地都可以找到，它常存于酸性火成巖中，有花崗巖的地方往往可以發(fā)現(xiàn)鉀長石。專業(yè)經(jīng)營生產(chǎn)礦建物資機電設(shè)備風動機械及配件于一體的綜合性工貿(mào)公司。中煤工礦公司擁有六個經(jīng)貿(mào)分公司，一個機械制造分公司。由此可見，采用熔模鑄造方法可大量節(jié)省機床設(shè)備和加工工時，大幅度節(jié)約金屬原材料。
熔模鑄造方法的另一優(yōu)點是，它可以鑄造各種合金的復(fù)雜的鑄件，特別可以鑄造高溫合金鑄件。
