| 更换冲击破碎机机架衬板时，如旧衬板取不下来时，可用气焊切割，并将机架内表面清理干净，衬板背面新浇铸的混凝土，是用500~600号水泥和砂子，比例是按质量比1:3混合，浇铸之前，衬板要打磨干净，使混凝土和它牢固结合起来。 When replacing the frame liner of impact crusher, if the old liner cannot be taken down, it can be cut by gas welding, and the inner surface of the frame shall be cleaned. The newly cast concrete on the back of the liner is mixed with 500 ~ 600 cement and sand in the proportion of 1:3 by mass. Before casting, the liner shall be polished to make the concrete firmly combined with it. 混凝土浇铸完之后，必须修整，使衬板背面的筋面与机架紧贴，并且一定要等混凝土干了之后方能投入使用，否则影响冲击破碎机使用寿命。 After the concrete is poured, it must be trimmed to make the reinforcement surface on the back of the lining plate close to the frame, and it must not be put into use until the concrete is dry, otherwise it will affect the service life of the impact crusher. 更换冲击破碎机圆锥衬板时，在切割衬板过程中切忌不要损伤锥体之间保持1~2毫米的间隙，最上面的衬板装上后，应先将压紧螺母装上，然后再浇铸锌合金，浇铸前，锥体与衬板先预热60~80℃，衬板各接头的间隙要用石棉及粘土塞住，以免锌合金漏出，待衬板浇完合金后，装上压紧螺母和锁紧板，使之紧紧固定。 When replacing the cone liner of impact crusher, do not damage the cone to maintain a clearance of 1-2mm during the cutting of liner. After the top liner is installed, install the compression nut first, and then cast the zinc alloy. Before casting, preheat the cone and liner 60-80 ℃, and plug the gap between the joints of liner with asbestos and clay to avoid the leakage of zinc alloy. Wait until the liner is poured out After alloy, install the compression nut and locking plate to make them firmly fixed. |
