Metal powder refers to a group of metal particles with a size less than 1mm. Including single metal powders, alloy powders, and certain refractory compound powders with metallic properties, they are the main raw materials for powder metallurgy. Metal powders are traditionally classified into five levels: coarse powder, medium powder, fine powder, fine powder, and ultrafine powder. Metal powders mainly include iron, tungsten, molybdenum, copper, cobalt, nickel, titanium, tantalum, aluminum, tin, lead and other powders, accounting for more than 2/3 of the total production of metal powders. Metal powders can be used as raw materials for powder metallurgy products or directly applied.

Purpose of metal powder screening

Remove impurities from metal powder and perform fine grading.

Introduction to Metal Powder Sieve

Metallurgical powder special sieve is a clean and environmentally friendly screening device designed to achieve the goal of removing impurities and fine grading in metallurgical powder under fully balanced and sealed conditions. It is a new type of screening equipment.

The metallurgical powder special sieve is used to filter the positive pressure airflow generated during the screening process through an air bag, air window, or equipped dust collector, and then discharge it, thereby balancing the air pressure inside and outside the sieve machine and even generating negative pressure; So it won't cause powder to fly, environmentally friendly and green; The dust generated by this machine is below 10mg/m ³. The ordinary screening machine adopts a simple closed method of only blocking the gas and not exhausting it. The movement of raw materials generates heat, causing the gas to expand and be trapped inside the machine, forming a malignant positive pressure gas. Therefore, no matter how tightly sealed the ordinary screening machine is, there will always be dust.

Characteristics of Metal Powder Sieve

The metallurgical powder special sieve is widely used in the screening of materials such as molybdenum powder, tungsten powder, nickel powder, cobalt powder, copper powder alloy powder, etc. Its main characteristics are as follows:

1. The pressure inside and outside the metallurgical powder special sieve is balanced, and there is a dust collector, which is dust-free and clean;

2. Metallurgical powder specialized screening components are formed by one-time rolling, modular production, and good sealing performance;

4. Recycling dust into the dust collector to prevent material waste;

5. Through CE standard certification, it is green, reliable, convenient, and reassuring.
