2PG系列对辊破碎机概述概述：对辊破碎机适用于抗压强度小于300Mpa，水份小于35%的硬、中硬、软物料的中碎和细碎作业，可广泛用于矿山、热电、水泥、陶瓷、冶金、化工、建材等行业，本机器具有使用维修费特低，性能可靠、粉尘少、噪音低等特点。对辊破碎机配置两个碾辊，根据用户需要的粒度，辊面分为平辊面和堆焊辊面两种机型，若物料的抗压强度超过200Mpa时均可选择加重机型。平辊面机型适用于进料粒度小于80mm，成品粒度要求50目-20mm的细碎作业。如利用鹅卵石、建筑垃圾人工制沙；矿业细碎铁矿石、石英石；陶陶行业破碎原材料；冶金行业破碎焦炭、生石灰；焦化厂细碎煤粉；化工行业破碎各种原料等；或者与上述类似的破碎场合。堆焊辊面机型适用于进料粒度小于110mm、成品粒度要求3-30mm的中细碎作业。水泥行业磨机前的预破碎水泥熟料、石灰石及复合材料；水煤浆行业入磨前预破碎煤；铁矿行业入磨前预破碎钢渣、铁矿石、硅矿石；制砖厂破碎各种矿石做免烧砖；热电厂破碎电煤；或者与上述类似的破碎场合。SummarizeDouble-roll crusher suitable for compression strength less than 300Mpa,humidity less than 30%of the hard,medium hard and soft materials,fine and intermediate crushing.Can be widely used in mining,thermal power,cement,ceramics,metallurgy,chemicals,building materials,etc.Features:olw use and maintenance costs,high reliability,low dust,low noise.Double-roll crusher has two abrasive rolls.Accouding to the user s,demand,the roll surface is divided into flat surface and overlay welding surface of two models.If the material s hardness is bigger than 200Mpa,heavier model is suitable.The flat roll model is for the fine crushing which requires the maxium feeding 80mm,range of discharge 0.3-20mm.Such as making sand with pebbles and constructiong waste,mining crushing iron ore,quartz stone;ceramics crushing raw materials;metallurgical industry cushing coke,lime;coking coal crushing plant;chemical industry crushing all kinds of raw materials;or in the similar occasions.The overlay welding roll model is for the medium fine crushing which requires the maxium feeding 110mm,range of discharge 3-30mm.For example,before the mill:cement industry pre-crushing cement clinker,limestone and composite materials;CWS industry pre-crushing coal;iron ore industry pre-crushing slag, iron ore, silica minerals;brick factory pre-crushing kinds of ore to produce unburned brick;thermal power plants crushing coal; or in the similar occasions.工作原理对辊破碎机是利用两个高强度耐磨合金碾辊，相对旋转产生的高挤压力来破碎物料，物料进入两辊间隙（V型破碎腔）以后，受到两碾辊相对旋转的挤压力和剪切力作用，在挤轧、剪切、和啮磨下，将物料破碎成需要的粒度然后从机器下部的排料口排出。Working principalDouble-roll crusher is fixed with two high-strength wear-resistant alloy rolls.Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space bwtween the two rolls,suffered both extrusion and shear force. In the crowd rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment.主要技术参数/Specifications序号Serial number规格型号Model进料粒度(mm)Feed size出料粒度（可调mm）Discharge size(adjustable)生产能力（t/h）Output电机功率（kw）Power电机功率加重型(kw) Powr of heavier mode保护方式Protection mode传动方式Driving mode12PG0404＜300.5-303-307.5 211 2弹簧或液压Spring or Hydraulic pressure三角带或联轴器Triangular blet or Shaft coupling22PG0605＜400.5-306-5015 218.5 232PG0806＜600.5-3010-10018.5 222 242PG1008＜800.5-3015-13022 230 252PG1209＜900.5-3030-25030 237 262PG1212＜900.5-3040-35045 255 272PG1612＜1100.5-3060-42075 290 282PG1618＜1100.5-3075-55090 2110 2
