破碎机筛网更换及紧固方式

1首先平移进料皮带输送机，留出换网空间，方便更换筛网。

2用内六角扳手逆时针拧开下料斗下方固定螺丝，然后平移抽出破碎机下料口。

3先用适当规格内六角扳手沿逆时针拆卸3颗黑色内六角螺丝，依次取出加厚垫片。

4用大力钳逆时针拆卸，固定筛网的尖头丝杆4个。

5 筛网调节杆，逆时针退100mm行程，筛网托架下移，即可取出筛网旧件。

6更换新筛网，需用叉车或者手动液压车辅助安装，将筛网放至筛网托架上。

7将筛网调节杆顺时针转动，筛网托架会逐步升起，如遇到卡顿现象，请勿继续转动筛网调节杆，逆时针转动筛网调节杆半圈，使用撬棒之类的工具，撬动筛网直至筛网处于活动状态，继续顺时针转动筛网调节杆，直至筛网到达合适的位置，需要检查筛网托架与筛网匹配度，±1-2mm，如果筛网与筛网托架匹配，均匀无缝隙。最后再依次顺时针转动固定筛网的箭头丝杆，筛网安装完毕。

8将破碎机下料口平移推进破碎机至合适位置，固定好螺栓，最后将输送带平移至破碎机进料口即可。

9如果不匹配，需要做好记号，调整筛网弧度。建议用折弯机或者锤子调整，调整完之后，重复第七步和第八步即可。

Crusher Screen Replacement and Tightening Method 

1.  First, move the feed belt conveyor horizontally to leave space for screen replacement, making it convenient for screen change.

2.  Use an Allen wrench to unscrew the fixing screws below the discharge hopper counterclockwise, then move and pull out the lower discharge port of the crusher.

3.  use Allen wrench to unscrew three black Allen screws counterclockwise, then sequentially remove the thick washers.

4.  Use a heavy-duty vice to unscrew in a counterclockwise direction, removing the four pointed screw rods that fix the sieve mesh.

5.  The sieve adjustment rod should be retreated 100mm in a counterclockwise direction, causing the sieve tray to lower, thus allowing the old sieve mesh to be removed.

6.   To replace the new sieve mesh, assistance from a forklift or manual hydraulic truck is required. Place the new sieve mesh onto the sieve tray.

7.  Adjust the sieve mesh regulating rod clockwise. The sieve mesh tray will rise. If you encounter any jamming, do not continue to turn the sieve mesh regulating rod. Instead, turn it counterclockwise by half a turn and use a crowbar or similar tool to lift the sieve mesh until it is in a movable state. Then, continue to turn the sieve mesh regulating rod clockwise until the sieve mesh reaches the appropriate position. You need to check the fit between the sieve mesh tray and the sieve mesh, ensuring it is within ±1-2mm and that there are no gaps. Finally, turn the arrow screw fixing the sieve mesh clockwise . The sieve mesh installation is complete.
8 Shift the discharge outlet of the crusher forward to position the crusher at the appropriate location, tighten the bolts, and then move the conveyor belt to align with the crusher's feed inlet.
9 If there is a mismatch, mark the necessary adjustments and modify the screen mesh curvature. It is recommended to use a bending machine or a hammer for this. After making the adjustments, repeat step 7 and 8
