检修改换滤网。筛网由薄钢板或铁皮冲制而成。当屏幕被异物磨损或损坏时,假如损坏面积不大,能够铆接或锡焊修复;假如屏幕损坏面积较大,应改换新的屏幕。装置筛网时,筛孔的毛刺侧应向内,润滑侧应向外,筛网片与筛框应严密配合。装置环形筛板时,堆叠的内残茬应沿旋转方向旋转,以避免物料在堆叠处卡住。

Check and modify the filter. The screen is made of thin steel plate or iron sheet. When the screen is worn or damaged by foreign bodies, if the damaged area is not large, it can be riveted or soldered to repair; if the damaged area of the screen is large, it should be replaced with a new screen. When installing the screen, the burr side of the screen hole should be inward, the lubrication side should be outward, and the screen sheet and the screen frame should be closely coordinated. When installing annular sieve plate, the stacked stubble should rotate along the rotating direction to avoid material being stuck in the stack.

轴承的光滑和改换。每运转300小时后,磨机应清洁轴承。假如轴承是用油光滑的,在添加新油时,好向轴承座加注1/3的间隙。大值不超越1/2。操作前,只能略微拧紧油杯盖。破碎机轴承磨损或损坏严重时,应及时改换,并留意增强光滑;运用圆锥滚子轴承时,应留意检查轴承的轴向间隙,使其坚持在0.2-0.4 mm。假如有任何不适,能够经过在轴承盖上增加或减少纸垫来调整。

Smoothing and replacement of bearings. After 300 hours of operation, the mill should clean the bearings. If the bearing is smooth with oil, it is better to add 1/3 clearance to the bearing seat when adding new oil. The maximum value does not exceed 1/2. Before operation, the oil cup cap can only be tightened slightly. When the bearing of crusher is seriously worn or damaged, it should be replaced in time, and pay attention to enhancing smoothness; when using tapered roller bearings, it should pay attention to checking the axial clearance of the bearing, so that it adheres to 0.2-0.4 mm. If there is any discomfort, it can be adjusted by adding or reducing the paper mat on the bearing cover.

三。改换钳子和锤子。破碎件中,破碎爪和破碎锤是饲料粉碎机的易损件,也是影响破碎质量和消费率的主要部件。破碎爪、锤磨损后应及时改换。改换卡爪时,应先拔出制动盘。拔出前,先翻开圆盘反面的圆螺母锁,用钩形扳手拧紧圆螺母,然后用专用拉具拔出圆盘。为了保证转子运转的均衡,换齿时应留意彻底改换。改换后应停止静均衡实验,使磨机工作稳定。装配卡爪时,必需拧紧螺母,不得漏装弹簧垫圈。换齿时应选用合格零件。单爪重量差不应小于1.0-1.5g。

Three. Change pliers and hammers. Crushing claw and hammer are the vulnerable parts of feed crusher, and they are also the main parts affecting crushing quality and consumption rate. The broken claws and hammers should be replaced in time after wear and tear. When changing the claw, the brake disc should be pulled out first. Before pulling out, first turn the round nut lock on the opposite side of the disc, tighten the round nut with a hook wrench, and then pull out the disc with a special puller. In order to ensure the balanced operation of the rotor, the teeth should be changed thoroughly. The static equilibrium experiment should be stopped after replacement to make the mill work steadily. When assembling claws, nuts must be tightened and spring washers must not be missing. Qualified parts should be selected when changing teeth. The weight difference of single claw should not be less than 1.0-1.5g.

一些锤式破碎机的锤是对称的。当锤头的尖角变钝时,可用于反角度调整。假如一端的两个角磨损,则应反向运用。调整角度或头部时,一切锤子应同时停止。锤子四角磨损后,应改换一切锤子。应留意,每组锤子的重量差不应大于5克。主轴、盘、定位套、销、锤装置终了后,应停止静均衡实验,坚持转子均衡,避免机组振动。另外,固定锤销轴和装置销轴圆孔由于磨损会逐步磨损,圆孔也会逐步磨损。销轴直径比原尺寸小1mm,圆孔直径比原尺寸大1mm时,应及时修理或改换。

The hammers of some Hammer Crushers are symmetrical. When the sharp angle of the hammer becomes blunt, it can be used to adjust the reverse angle. If two corners of one end are worn out, they should be used in the opposite direction. When adjusting the angle or head, all hammers should stop at the same time. After the four corners of the hammer are worn out, all hammers should be replaced. It should be noted that the weight difference of each group of hammers should not be greater than 5 grams. When the spindle, disc, positioning sleeve, pin and hammer are finished, the static balancing experiment should be stopped, and the rotor balancing should be insisted to avoid the vibration of the unit. In addition, the round holes of fixed hammer pin shaft and device pin shaft will gradually wear out due to wear, and the round holes will also gradually wear out. When the diameter of pin shaft is 1 mm smaller than the original size and the diameter of round hole is 1 mm larger than the original size, it should be repaired or replaced in time.
