1200立式冲击破碎机的设计.doc

济南大学毕业设计22摘要PL-1200立式冲击破碎机是一种结构轻巧、效率高的立式冲击破碎机，适用于各种矿物的研磨与细碎，特别对中硬、特硬以及腐蚀性材料比其他类型的破碎机更具有优越性。主要由进料斗、分料装置、转子、涡动破碎腔、机架、驱动装置等组成。具有径向发射通道的转子在涡动破碎腔内高速旋转，转子径向发射通道和破碎腔内都可以形成驻留物料，形成物料衬层，物料进入破碎机后，经过分料装置后，在转子中被加速后高速发射出去，从而形成连续的物料幕，在涡动破碎腔内自行撞击与磨碎，一块物料在破碎腔内会进行多次撞击，保证了破碎效果。破碎后的物料从机架两侧的排料通道连续不断的排出，因为破碎过程中进行的是物料之间的碰撞与研磨，此过程中无金属磨损。此破碎机目前在人工砂的制作工艺中得到了广泛使用。关键词：立式冲击破碎机；涡动破碎腔；转子；石打石ABSTRACTPL-1200verticallashcrusherisakindoflight-structuredandefficientmachine,whichcanbeappliedtogrindandcomminuteallkindsofminerals.Comparedwithotherkindsofcrusher,itismoreproficientatgrindingminerals,especiallythatofthesecondary-solidity,special-gradesolidityandcausticones.Itismainlycomposedofbunker,stuff-dividingapparatus,rotor,whirlpoolmovetatteringcavity,structureanddrivingapparatus.Thewholeworkingprocesscanbedescribedasfollows:therotorwithradial-directionaltunnelspinatahighspeedinthewhirlpoolmovetatteringcavity,thenremainingmaterialswhichcanbemadeinthelaunchingtunnelofrotorandtatteringcavitydevelopintomaterial-lininglayer;thefollowingstepisthatthematerialslaunchedoutatahighspeedcomeintocrusherdevelopintoconsecutivedownfallofstuff;atlast,havingbeencollidedandcomminutedinthewhirlpoolmovetatteringcavityformanytimes,themineralscanbegrandfully.Thegrand-stuffcanbeexcavatedcontinuallyfromthepumping-tunnelofthestructure.Becausethewholeprocessiscarriedoutbetweenthematerials,thereisnometalerosions.Sofar,thismachineiswidelyadoptedinthetechnologyofhand-madesand.Keywords：verticallashcrusher;whirlpoolmovetatteringcavity;rotor;stone-hit-stone目录摘要………………………………………………..…….….……………...IABSTRACT…………….……………………..…………….II1前言....................................……….…………………………………………….….……11.1研究的目的和意义................................................………….………….………..11.2PL-1200立式冲击破碎机的特点......……….......…………….………….………..21.3破碎机产品粒度的控制及影响因素……………………….…....……..………61.4立式冲击破碎机国内外现状与发展……………………….…....……..………62总体结构设计......................……..….………………………….…..….………….82.1总体结构和工作原理………………………………………………………..82.2主要参数…………………………….………………...………………..….….102.3功
