Product Introduction
>Product Introduction
Jaw crusher is a crushing machinery that uses the squeezing and bending effects of two jaw plates on mineral to First or Second crush various hardness mineral.
This Jaw crusher consists of a fixed jaw plate and a movable jaw plate. When the two jaw plates approach, the ore is crushed. When the two jaw plates leave, the ore blocks smaller than the discharge port are discharged from the bottom.
Its breaking action is intermittent. This type of crusher is widely used in industrial sectors such as mineral processing, building materials, silicates, and ceramics due to its advantages of simple structure, reliable operation, and ability to crush hard materials.
1. Jaw plates
Jaw plates is the consumable spare part of Jaw crusher machinery , be used to Crush & Smash the minerals / rocks or other raw material. this crusher jaw plates should have longer life with high hardness, lower wear-rate & breakage rate, so used high Manganese alloy or high Chromium alloy material to make, casting by advanced automatic casting line, finished product with special heat-treatment, will improve this hammer product quality and life !
2.Side liner
This spare wear part of Jaw cruser be used to protect the machine will not broken by ore impact during operation, should have longer life with high hardness, lower wear-rate & breakage rate.
>Product Advantage
Relatively stable quality
High Manganese-Chromium alloy steel cast ware parts have been used with a longer usage time history than other kind materials.
NGZR have more than 10 years experience of R&D / Manufacutring / After-sales srevice for High Mn & High Cr casting wear parts (such as high Chrome casting gridning media and high Mn-Cr alloy cast mill liner & crusher liner & Jaw plate etc.) in Mining and Cement Indusries.
Lower usage cost
Mn-Cr alloy steel cast waer part (Jaw plates & Liner) have long usage life with stable quality. Because NGZR have large production capacity with Advanced Lost foam process full Automatic precision casting line and Resin-sand Wooden mould manual casting production line, we can provide more competive price products to all customers to help customer get lower production unit cost than before.
Customized alloy Steel composition
NGZR foundry was able to match customer needs to readjust the Chemical Composition of alloy steel content (Mn /Cr) , or increased other special metallic element (Si /Mo /Cu /Ni etc), through special heat-treatment processing, can help this casting crusher liner & Jaw plate achieve to special Mechanical performance, to follow different customer’s different working conditions.
Customized drawing size and shape
NGZR foundry can follow customer’s drawing of exist jaw crusher wear part to customized . Also we can revised the exist wear parts shape / thickness and wearing quality to help customer get lower wear-parts cost and higher production efficiency.
Door to door measure & Installation Guide
If customer can’t provide drawing of existing hammer crusher, NGZR will arrange our service engineer come to measuring and design of the one-stop service with free of charge.
If customer required, NGZR provide door to door installation guide serivce with pay charge.

How to choose correct alloy material and shape to reduce production cost?
1.Fit the existing Jaw crusher to choose Jaw plates Alloy material
High Mn-Cr alloy steel have good impact toughness, should not be broken;
High Cr alloy steel have good hardness & wear-rate than Mn-Cr alloy, but easy to broken;
2.Fit the RCM to choose the alloy steel
The RCM ( reliability-centered maintenance) time of crusherl become loner, the crusher liner and Jaw plate should be have more hardness. However, the product hardness increased, that will be used more expensive alloy material such as Mo / Ni / Cu / Cr / Mn etc, that will be increased the product price and unit usage cost.
3.Design the better shape of crusher liner & Jaw plates
The better shape of Jaw plates & liner will help crusher have more effective crushing, increased the production capaciy and quality!
NGZR can help customer to Research & Develop the Jaw platea & liner shape for existing hammer crusher machiery.
