Product Introduction
>Product Introduction
Metal crusher (also known as metal grinder), is a machine that crushes waste metal materials.
Metal crusher can crush various scrap metal and other waste materials such as plastic/rubber/circuit boards into shapes and sizes that are easy to handle,
The external forces applied to the waste solid materail during the crushing process include rolling, shearing, impact, and grinding. Rolling is mainly used for coarse and medium crushing, suitable for crushing hard materials and large blocks; Cutting is mainly used for fine crushing, suitable for crushing tough materials; Impact is mainly used for medium crushing, fine grinding, and ultrafine grinding, suitable for crushing brittle materials; Grinding mainly involves fine grinding and ultrafine grinding, suitable for crushing small pieces and fine particles. The actual crushing process often involves several external forces acting simultaneously.
1. Knife /Hammer head
The knife head is the most important working component of a metal crusher. This knife hammer is made of a new high-quality Cr-Mn alloy steel composite casting, its service life is better than other alloy material.
2. Crusher liner & Sieve plate
The crusher liner protect the crusher machinery not destory by waste material crushing process.
>Product Advantage
Relatively stable quality
High Mn-Cr alloy steel casting mill liners 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 (knife hammer & 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. So customer will 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 cast crusher liner & Impact plate & Plate hammer 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 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 metal 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.

>Product design & uses
How to choose correct alloy material and shape to reduce production cost?
1.Fit the existing crusher to choose knives hammer material
The knife hammer head is made of a new high-quality Cr-Mn alloy steel composite casting, its service life is several times that of ordinary hammerheads.
2.Fit the RCM to choose the liner thickness size
The RCM ( reliability-centered maintenance) time of crusherl become loner, the crusher liner thickness size should be increased. However, the liner thickness size increased, the liner total weight will enlarge, so the liner purchased cost will rised.
3.Design the better shape of crusher liner & hammer
The better shape of hammer & liner will help crusher have more effective crushing, increased the production capaciy and quality!
NGZR can help customer to Research & Develop the hammer & liner shape for existing hammer crusher machiery.
