Guidelines for the Proper Use of Biomass Pellet Machines

As core equipment for biomass energy production, biomass pellet machines play a vital role in converting agricultural and forestry residues into high-efficiency, eco-friendly solid fuels. Proper operation ensures safe production, boosts equipment output and performance, and extends its service life. Below are detailed guidelines for the rational use of biomass pellet Machines.

Guide for the Proper Use of Biomass Pellet Machines

I. Pre-Operation Preparation

(1) Basic Pre-Operation Requirements

Before operation, operators must read the user manual carefully and familiarize themselves with all the equipment's technological processes. During production, strictly follow the operating procedures and sequence, and complete installation as required. Smoking and open flames are strictly prohibited in the production area to eliminate safety hazards.

(2) Installation Requirements

For long-term fixed operation, install the biomass pellet machine on a concrete foundation (secure the main machine to a horizontal cement floor with tightened screws). For frequent position changes, mount the pellet machine and motor together on an angle iron frame. If using a diesel engine, ensure its output power is slightly higher than the pellet machine’s for proper matching. Also, align the pulley grooves and keep their ends flush to avoid transmission issues.

(3) Pre-Operation Inspection

After installation, check all fasteners and tighten any loose ones. Also, verify the drive belt tension and ensure the motor shaft is parallel to the pellet machine shaft for smooth transmission.

(4) Rotation and Lubrication Inspection

Before starting, manually rotate the motor rotor to check that gears, hammers and the rotor operate smoothly with no internal collisions. Confirm the rotor rotation matches the machine’s arrow indicator and ensure all lubrication points are well-oiled to prevent dry friction damage.

(5) Pulley Usage Specifications

Never replace the pulley arbitrarily. This prevents crushing chamber explosions from excessive speed or reduced efficiency from insufficient speed, ensuring equipment operates within design parameters.

II. Operation Process Guide

(1) Idle Operation Requirements

After starting, let the equipment idle for 2-3 minutes. Start feeding only after confirming the pressure wheel rotates normally against the mold with no abnormal noise. Avoid direct feeding without idling to prevent malfunctions.

(2) Operation Monitoring

Monitor the equipment closely during operation. Feed uniformly to prevent blockages and stalling; never run the equipment overloaded for long periods. If vibrations, abnormal noises, overheating, or material spraying occur, stop immediately, inspect, and resolve the issue before restarting.

(3) Raw Material Inspection

Inspect raw materials carefully to keep hard objects (copper, iron, stones) out of the crushing chamber, which could cause accidents. Never put stones, metals, or other foreign objects into the feeder. Remove iron before granulation to protect the granulation chamber.

III. Safety Operation SpecificationsIII. Safety Operation Specifications

Operators must not wear gloves during operation. Stand beside the pellet machine when feeding to avoid rebounding debris hitting the face. Never use hands or tools to stir materials while the equipment is running to prevent injury.

Operators are strictly prohibited from wearing gloves during operation. When feeding, stand on the side of the pellet machine to prevent rebounding debris from hitting the face. During the operation of the equipment, it is strictly prohibited to use hands or other tools to stir materials to avoid personal injury.

(1) Abnormal Handling Specifications

If abnormal noise occurs during production, cut off power immediately. Inspect and resolve the issue completely before restarting; never operate with faults.

If abnormal noise occurs during production, cut off the power supply immediately. Only after a comprehensive inspection and proper handling of the abnormal situation can the machine be restarted for production. Operation with faults is strictly prohibited.

(2) Shutdown Operation Requirements

Before shutting down, first stop auxiliary feeding, then add oil. Shut down the machine only after the mold holes are filled with oil and there is no residual oil in the granulation chamber. The purpose of adding oil is to facilitate smooth material discharge and reduce equipment startup resistance in the next production.

Proper operation per this guide extends equipment life, improves output and stability, and lowers maintenance costs.

Strictly operating the biomass pellet machine in accordance with this guide and paying attention to all precautions can not only improve the equipment's output and operation stability, but also effectively extend the service life of the equipment and reduce maintenance costs.
