移动破碎机鄂板如何减少磨损
How to Reduce Wear of Moving Crusher Jacket
1.设备参数与物料相顺应
1. Compatibility of equipment parameters with materials
对每批物料停止抽检,发现物料性质有较大幅度的动摇时,及时调整破碎机的各项次要参数,如钳角、公平轴转速、产量和电动机功率等,使之与进机破碎机物料相顺应,增加颚板的磨损。
When the sample inspection is stopped for each batch of materials and it is found that the properties of the materials are greatly shaken, the minor parameters of the crusher, such as clamp angle, fair shaft speed, output and motor power, are adjusted in time to make them conform to the materials of the crusher and increase the wear and tear of the jaw plate.
2.留意紧固鄂板
2. Pay attention to tightening the jaw plate
新装颚板要留意紧固,并确保颚板与机体(动、静颚)的外表接触颠簸。可在两外表之间垫层铅板、胶合板水泥砂浆等塑性较好的资料。对动颚板和静颚板的拆卸要求是颚板的赤峰对准另一个颚板的齿槽,即活动颚板与固定颚板出于根本啮合形态。
The new jaw plate should be tightened carefully, and ensure that the jaw plate and the body (dynamic and static jaw) surface contact bumps. Good plasticity data such as lead sheet and plywood cement mortar can be obtained between the two surfaces. The removal of the moving jaw plate and the static jaw plate requires that the Chifeng of the jaw plate be aligned with the alveolus of the other jaw plate, that is, the movable jaw plate and the fixed jaw plate are in the fundamental meshing form.

3.鄂板的材质选择
3. Material Selection of Eupatorium Plate
颚板要选用硬度高的材质以抵抗挤压显微切削生效,选用有足够韧性的材质,以抵抗凿削撞击发生的疲劳生效。通常选用含锰12%~14%的高锰钢铸成颚板。小型颚式破碎机也可用白口铸铁制造颚板,同时在齿板构造上停止改良,增加物料与齿板的绝对滑动。由于颚板通常被制成上下对称外形,故可在小修时将下部已磨损了的颚板倒置过去运用。
The jaw plate should be made of material with high hardness to resist extrusion micro-cutting and material with enough toughness to resist the fatigue effect caused by chipping impact. High manganese steel containing 12%~14% manganese is usually used as jaw plate. Small jaw crusher can also use white cast iron to make jaw plate. At the same time, it can stop improving the structure of the tooth plate and increase the absolute sliding between the material and the tooth plate. Since the jaw plate is usually made into upper and lower symmetrical shape, it can be used in the past to reverse the worn lower jaw plate during minor repairs.
4.互换同型鄂板
4. Exchange of the same type of jaw plate
拥有矿山破碎工艺线的水泥企业,可以将矿山粗碎和水泥厂细碎的同型磨损颚板互相对换,替代新颚板持续发扬作用。
Cement enterprises with mine crushing technology line can exchange the same type of wear jaw plate between mine crushing and cement plant crushing, and replace the new jaw plate to continue to develop.
5.采用堆焊或电弧焊
5. Surfacing or arc welding
关于已磨损生效的颚板,可采用堆焊的方法,使齿形恢复。修复时可采用电弧焊,也可采用自动埋弧堆焊。
For the worn jaw plate, surfacing can be used to restore the tooth shape. Arc welding or automatic submerged arc surfacing can be used in repairing.
