Magotteaux is a leading global manufacturer of crusher wear parts and professional VSI crushing equipment, with over a century of industrial experience and advanced metallurgical technology. The Mag’Impact 2100 (MAG2100) is one of its most popular mid‑range VSI crushers, widely used in aggregate shaping, manufactured sand production, mineral crushing and construction waste recycling.

The MAG2100 Impeller (core part numbers: QCA313, QCA102) is the core rotating wear component of the MAG2100 VSI crusher. It directly determines crushing efficiency, the cubicity of finished sand, and the overall stable operation of the equipment. As the most frequently replaced key wear part, its working principle, fixing structure and material quality are critical to reducing plant downtime and operating costs.

MAG2100 Impeller Working Principle

The MAG2100 Impeller is the core power and material acceleration component of the vertical shaft impact crusher. It uses a high‑speed rotary impact crushing principle, and its working principle is precise and efficient:

After raw materials fall into the center of the high‑speed rotating MAG2100 Impeller, the impeller’s internal flow channels evenly distribute the materials to each outlet. Driven by strong centrifugal force, the impeller accelerates stone and sand materials to ultra‑high linear velocity, then throws them outward uniformly.

The ejected high‑speed materials collide violently with the static cavity anvil blocks or the material stone bed formed in the crushing chamber. Through continuous impact, friction and splitting, the materials complete crushing, shaping and fine sand making. Meanwhile, the MAG2100 Impeller can stabilize the material discharging trajectory, effectively optimize the particle shape of finished aggregates, reduce flakiness and improve the overall quality of finished sand and stone.

In actual operation, the impeller bears dual loads of high‑speed material abrasion and frequent impact force. Once the impeller is worn, deformed or unbalanced, it will cause rotor vibration, uneven feeding, reduced output and poor aggregate cubicity, seriously affecting production efficiency.

Material Solutions for MAG2100 Impeller

Saikuang is a professional manufacturer of aftermarket VSI crusher wear parts, specializing in the production of fully compatible MAG2100 Impeller (QCA313, QCA102). We offer three material options for the MAG2100 Impeller: High Chrome 26%, High Chrome 26% with Ceramic, and High Chrome 26% with Tungsten Carbide, matching different customer working conditions. All products undergo strict heat treatment, hardness testing, dimensional inspection and non‑destructive flaw detection to eliminate casting defects, ensure stable dynamic balance and excellent wear resistance, completely matching the working performance of original parts.

High Chrome 26%

This is the standard high‑chrome material with 26% chromium content. It has balanced wear resistance and impact toughness, fine and uniform internal metallographic structure, and strong resistance to particle scratching and abrasive wear. It is suitable for medium‑abrasive materials such as limestone, river pebble, recycled concrete and ordinary aggregate. It can meet the daily sand making and shaping needs of conventional crushing plants, with cost‑effective performance and stable service life.

High Chrome 26% with Ceramic

Based on the 26% high‑chrome matrix, this grade is reinforced with embedded ceramic particles. The combination perfectly merges the high toughness of the metal matrix with the ultra‑high wear resistance of ceramic. It is mainly used for crushing high‑hardness materials such as granite, basalt and quartz stone. Compared with standard high chrome 26%, the ceramic‑reinforced MAG2100 Impeller delivers significantly longer service life, reducing frequent replacement and production shutdown loss.

High Chrome 26% with Tungsten Carbide

This grade further enhances the 26% high‑chrome matrix with tungsten carbide reinforcement. Tungsten carbide provides extreme hardness and excellent anti‑abrasion performance, making it ideal for the most demanding high‑abrasion and high‑impact applications. It is particularly suitable for crushing hard rock, ore and other highly abrasive materials. The tungsten carbide reinforced MAG2100 Impeller offers the longest wear life among the three options, effectively minimizing downtime and maximizing productivity.
