High Abrasion Resistant Alloy Cast Blades Of Spiral Classifier Machinery For Mineral Processing Plant

Product Introduction

Product Overview

The spiral classifier (Screw classifier) is a piece of mineral processing equipment. This mechanical classification device exploits the fact that solid particles of different specific gravities settle at different speeds in liquid. It screens the mineral powder ground in the mill, uses spiral blades to carry the coarse material back into the mill feed inlet, and sends the screened fine material out through the overflow pipe.
In mineral processing plants, spiral classifiers are paired with ball mills to build a closed-circuit loop that separates mineral sand. They also serve gravity beneficiation plants for grading ore sand and fine mud, handle particle size classification of slurry in metal beneficiation, and perform desliming and dewatering in mineral washing operations.

1. Classifier Blades
The blade is the most critical working part of a classifier, so it needs highly abrasion-resistant material. It is cast as a composite from a new, high-quality Cr-Mn alloy steel, and it lasts longer in service than blades made from other alloy materials.

Key Advantages

Fairly consistent quality
Compared with other materials, cast wear parts of High Mn-Cr alloy steel have a longer record of use.
NGZR has over 10 years of experience in R&D, manufacturing and after-sales service for high manganese & high chromium alloy cast wear parts, such as high chrome cast grinding media, high Mn-Cr alloy cast mill liners and crusher wear parts, for the mining, cement and aggregate industries.

Reduced operating cost
Cast wear parts of Mn-Cr alloy steel combine a long service life with consistent quality.
NGZR has a large production capacity, an advanced lost foam process, a fully automatic precision casting line and a manual resin-sand wooden mould casting production line. Therefore we can supply more competitively priced products, which brings customers a lower unit production cost than before.

Tailored alloy steel composition
To follow customer requirements, the NGZR foundry can adjust the chemical composition of the alloy steel (Mn /Cr) or add other special metallic elements (Si /Mo /Cu /Ni, etc). Together with special heat treatment, this gives these cast wear parts particular mechanical properties that fit each customer's different working conditions.

Custom drawings, sizes and shapes
The NGZR foundry can customize screw classifier wear parts based on the drawing of the customer's existing ones. We can also modify the shape, thickness and abrasion resistance of the existing parts, helping customers cut purchase cost and raise production efficiency.

On-site measurement & installation guidance
Should a customer be unable to supply a drawing of the spiral classifier currently in use, NGZR will send a service engineer free of charge to measure it and design the solution, as part of a one-stop service.
On request, NGZR can offer a door-to-door installation guidance service, which is paid.
