100–1000 KG Semi-Automatic Powder Hook Scale Packaging Machine

Product Introduction

This machine is designed for packaging 100–1000 kg of powders, including ultra-fine materials. It is widely used in new energy, chemical, pharmaceutical, and food industries. Integrating weighing, compaction, de-aeration, and dust collection, it ensures stable, accurate, and clean packaging while improving efficiency and reducing manual work.

Features

Loss-in-weight weighing method, vibration compaction, air-bag bag clamping, no-drop filling design, de-aeration system, and built-in dust collection. It also features an independent weighing structure, integrated check weighing and vacuum sealing, and a mobile conveyor system.

Problems Solved
Effectively solves issues such as inaccurate weighing, heavy dust, loose filling, air entrapment, and low efficiency, ensuring precise, dense, and efficient powder packaging.

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 + Vertical) de-aeration screw / Vertical screw

Typical Industries

Widely used in new energy battery, fine chemical and advanced materials, pharmaceutical, food, powder & functional materials, mineral & inorganic materials, and energy & environmental protection industries.
