2PG系列對輥破碎機概述概述：對輥破碎機適用于抗壓強度小于300Mpa，水份小于35%的硬、中硬、軟物料的中碎和細碎作業(yè)，可廣泛用于礦山、熱電、水泥、陶瓷、冶金、化工、建材等行業(yè)，本機器具有使用維修費特低，性能可靠、粉塵少、噪音低等特點。對輥破碎機配置兩個碾輥，根據(jù)用戶需要的粒度，輥面分為平輥面和堆焊輥面兩種機型，若物料的抗壓強度超過200Mpa時均可選擇加重機型。平輥面機型適用于進料粒度小于80mm，成品粒度要求50目-20mm的細碎作業(yè)。如利用鵝卵石、建筑垃圾人工制沙；礦業(yè)細碎鐵礦石、石英石；陶陶行業(yè)破碎原材料；冶金行業(yè)破碎焦炭、生石灰；焦化廠細碎煤粉；化工行業(yè)破碎各種原料等；或者與上述類似的破碎場合。堆焊輥面機型適用于進料粒度小于110mm、成品粒度要求3-30mm的中細碎作業(yè)。水泥行業(yè)磨機前的預破碎水泥熟料、石灰石及復合材料；水煤漿行業(yè)入磨前預破碎煤；鐵礦行業(yè)入磨前預破碎鋼渣、鐵礦石、硅礦石；制磚廠破碎各種礦石做免燒磚；熱電廠破碎電煤；或者與上述類似的破碎場合。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.工作原理對輥破碎機是利用兩個高強度耐磨合金碾輥，相對旋轉產(chǎn)生的高擠壓力來破碎物料，物料進入兩輥間隙（V型破碎腔）以后，受到兩碾輥相對旋轉的擠壓力和剪切力作用，在擠軋、剪切、和嚙磨下，將物料破碎成需要的粒度然后從機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.主要技術參數(shù)/Specifications序號Serial number規(guī)格型號Model進料粒度(mm)Feed size出料粒度（可調mm）Discharge size(adjustable)生產(chǎn)能力（t/h）Output電機功率（kw）Power電機功率加重型(kw) Powr of heavier mode保護方式Protection mode傳動方式Driving mode12PG0404＜300.5-303-307.5 211 2彈簧或液壓Spring or Hydraulic pressure三角帶或聯(lián)軸器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
