100–1000 KG Semi-Automatic Powder Net Weighing Packaging Machine

Product Introduction

This machine is specially designed for 100–1000 kg powder packaging, including ultra-fine powders. It is widely used in new energy battery, fine chemical, pharmaceutical, and food industries. Featuring vibration compaction, de-aeration filling, and no-drop feeding, it effectively reduces dust, improves filling density, and ensures accurate weighing. Equipped with a dust collection system and independent weighing structure, it delivers clean, stable, and precise packaging. A mobile conveyor system also helps improve efficiency and reduce manual labor.

Features

Vibration compaction system, pneumatic airbag bag clamping, no-drop filling design, de-aeration device, self-cleaning dust collection system, mobile conveyor, dust hood, and independent weighing structure for stable and reliable performance.

Problems Solved
Effectively solves issues such as heavy dust, loose filling, material blockage, inaccurate weighing, and low efficiency. It improves material density, reduces dust pollution, ensures stable weighing, and enhances overall packaging efficiency.

Applicable Materials

Suitable for 100–1000 kg of ultra-fine powders and various powder materials, including dry materials, high air-content materials, low bulk density materials, and dust-prone materials.
Examples include: ultra-fine graphite powder, lithium battery materials (LFP, cathode and anode materials), silica powder, coal powder, matting agents, additives, dry chemical powders, toner, dyes, pearlescent powders, wettable powders, ternary materials, and other ultra-fine powders.

Feeding Method

Vertical de-aeration screw / Horizontal twin screw / Electromagnetic vibration / Rotary valve
