Alloy Cast Knife Hammer & Liner for Metal Shredder (Scrap & Waste Metal Recycling)

Product Introduction

Product Introduction

A metal crusher (also known as a metal grinder) is a machine that crushes waste metal materials.
A 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 material 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 materials.

2. Crusher liner & Sieve plate
The crusher liner protects the crusher machinery not destory by the 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 kinds of materials.
NGZR has more than 10 years of experience in R&D / Manufacturing / After-sales service for High Mn & High Cr casting wear parts (such as high Chrome casting grinding media and high Mn-Cr alloy cast mill liner & crusher liner & Jaw plate etc.) in Mining and Cement Industries.

Lower usage cost
Mn-Cr alloy steel cast wear parts (knife hammer & Liner) have a long usage life with stable quality. Because NGZR has large production capacity with an advanced lost foam process, full Automatic precision casting line, and a resin-sand wooden mould manual casting production line, we can provide more competitive price products to all customers. So customers 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 increase other special metallic elements (Si /Mo /Cu /Ni, etc), through special heat-treatment processing, which can help this cast crusher liner & Impact plate & Plate hammer achieve special Mechanical performance, to follow different customers’ different working conditions.

Customized drawing size and shape
NGZR foundry can follow the customer’s drawing of existing crusher wear parts to customize. Also, we can revise the existing wear parts shape/thickness and wearing quality to help customers get lower wear-parts cost and higher production efficiency.

Door-to-door measurement & Installation Guide
If the customer can’t provide drawings of the existing metal crusher, NGZR will arrange for our service engineer to come to measure and design the one-stop service at no charge.
If the customer requires, NGZR will provide door-to-door installation guide serivce with pay charge.
