煤的转鼓试验机,用于测定煤炭易碎性和粉尘指数. 煤的转鼓试验机，测定块煤在运输过程中抗破碎能力的设备。主要用于测定褐煤、烟煤、无烟煤等块煤的易碎性 和粉尘指数 ）。将规定粒度25-50mm块）和质量的煤样放入转鼓中，以规定的转速转速 40 r/min旋转规定的转数2400转。煤样在鼓内通过跌落、摩擦和碰撞产生破碎。试验结束后进行筛分，根据各粒度级煤的质量变化，计算平均粒度减少百分率。 技术参数名称 煤的转鼓试验机 测定对象 原煤、块煤 测定指标 易碎性、粉尘指数 核心参数 转 2400转，转速 40 r/min 执行标准 MT/T 1012, ASTM D441 试验步骤 制样：按照 GB 475 标准采取煤样，并筛分出规定粒度范围（如 25mm-50mm）的块煤。称量：称取一定质量的煤样（具体质量视标准要求而定）。运行：将煤样放入转鼓，设定转数为 2400转，启动机器。筛分：试验结束后，取出煤样，使用标准筛（如 38mm, 25mm, 13mm, 6mm, 3mm, 1mm 等）进行筛分。计算：称量各粒级煤的质量，计算易碎性指数和粉尘指数。LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;min-height:auto;max-height:none;min-width:auto;max-width:none;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransPARency="true" scrolling="no" allow="attribution-reporting; run-ad-auction" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&lmt=1776062744&plaf=1%3A2&plat=1%3A128%2C2%3A128%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C41%3A32%2C42%3A32%2C43%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&pra=5&aiof=9&asro=0&itsi=9&aiapmd=0.0001&aiapmid=1&aiactd=0&aicctd=0&ailctd=0&aimartd=4&aieuf=1&aicrs=1&uach=WyJXaW5kb3dzIiwiMC4xLjAiLCJ4ODYiLCIiLCIxMzAuMC42NzIzLjQ0IixudWxsLDAsbnVsbCwiNjQiLFtbIk5vdD9BX0JyYW5kIiwiOTkuMC4wLjAiXSxbIkNocm9taXVtIiwiMTMwLjAuNjcyMy40NCJdXSwwXQ..&abgtt=6&dt=1776062744623&bpp=12&bdt=41&idt=66&shv=r20260408&mjsv=m202604070101&ptt=9&saldr=aa&cookie=ID%3D76e5dcfe79ebe321%3AT%3D1776062137%3ART%3D1776062439%3AS%3DALNI_MYDbb1UBSd3nRedm4TJmXz0MQ48aw&gpic=UID%3D00001250ea586851%3AT%3D1776062137%3ART%3D1776062439%3AS%3DALNI_Mb1cSRe__yd11eBZ6KbqLTa2675mQ&eo_id_str=ID%3Df9b330ed3036467e%3AT%3D1776062137%3ART%3D1776062439%3AS%3DAA-AfjZJKv6t51tgN4j53S5iSzE-&nras=1&correlator=5948211867898&frm=23&ife=1&pv=2&nhd=1&u_tz=480&u_his=19&u_h=900&u_w=1600&u_ah=860&u_aw=1600&u_cd=24&u_sd=1&DMC=8&adx=-12245933&ady=-12245933&biw=1583&bih=719&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=95385799%2C95387623%2C95386955%2C95388044%2C95379824&oid=2&pvsid=6068713817704939&tmod=1258364296&uas=0&nvt=1&fsapi=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&fc=1664&brdim=0%2C0%2C0%2C0%2C1600%2C0%2C1600%2C860%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&plas=260x567_l%7C308x567_r&bz=1&ifi=1&uci=1.nc4xxj2yes4k&fsb=1&dtd=105" data-google-container-id="1.nc4xxj2yes4k" tabindex="0" title="Advertisement" aria-label="Advertisement" data-load-complete="true"> |
