850 Vertical Ring‑Die Biomass Pellet Mill

Product Overview

Model 850 vertical ring‑die biomass pellet mill is a large‑size industrial pelleting host. It adopts static ring‑die, rotating‑roller vertical centrifugal feeding structure, developed for high‑capacity demand of large‑scale biomass fuel plants. It efficiently presses sawdust, wood shavings, bamboo dust, rice husk, peanut shell, palm EFB, straw, branch chips and other agro‑forest waste into premium‑quality bio‑fuel pellets.

The whole machine adopts fully reinforced heavy‑duty design for long‑term full‑load continuous operation. Rarely used standalone, mostly combined with crusher, dryer, pellet cooler and packing machine to form complete large‑scale pellet production line. It serves as core main machine for large overseas biomass‑energy projects.

Key Advantages

1. Extra‑heavy high‑torque hardened gear transmission system: Oversized gearbox and thickened main shaft for excellent impact‑resistance and heavy‑load performance. Fully‑automatic closed‑loop circulating oil circuit continuously cools and lubricates gears and bearings, supporting 24‑hour full‑load non‑stop production for year‑round factory operation.
2. Oversized vertical feeding structure: Widened & thickened stainless‑steel feeding chamber for large throughput. Uniform centrifugal material distribution. Excellent adaptability for high‑fiber fluffy straw and palm materials, greatly reducing blockage risk.
3. Large‑size heavy‑duty wear‑resistant die‑roller assembly: Enlarged pelleting chamber. Alloy‑steel ring die with vacuum quenching treatment; high‑strength anti‑wear alloy rollers. Pellet size 6‑12 mm by replacing ring die. High forming rate with hard, stable‑quality final pellets.
4. Heavy‑duty modular maintenance design: Enlarged quick‑open access door for convenient die and roller replacement. Independent discharging unit. Standardized components for easy spare‑parts stock in overseas factories.
5. International‑working‑condition adaption: Multi‑country custom voltage available. CE‑relevant documents can be provided. Every machine passes load test before delivery. Full‑set electric control system and auto‑lubrication system as standard supply.
6. Project‑level export‑oriented service: 1‑year warranty for whole machine. Complete plant layout & process solution available. Remote technical support, optional overseas on‑site installation & commissioning training. Long‑term supply of original wearing parts.
