Cold Compression Strength Test Machine

STANDART: ISO 4700, ASTM E 382, IS 8625

LT-M0100 Cold Compression Strength Test Machine

PRODUCT DETAILS

The Cold Compression Strength Test Machine is a fully automatic system designed to determine the crushing strength of iron ore pellets by measuring the compressive load required to cause pellet breakage. The system combines automatic feeding, controlled compression, statistical evaluation and digital test-data management.

Pellet crushing strength: Determines the maximum compressive load required to break individual pellets.
10 kN test capacity: Provides a maximum compression load of approximately 1,000 kgf.
8–12 mm pellet size: Designed for standard iron ore pellet samples within this size range.
60–1000 pellet test batches: Supports both routine and high-volume testing.
Automatic feeding system: Vibrating feeder transfers pellets individually to the test area.
Selectable compression speed: 5, 10, 15 or 20 mm/min.
Automatic cleaning: Air-jet system removes broken pellet fragments from the testing area.
Automatic sample handling: Encoder-controlled mechanism transfers tested pellets after crushing.
7-inch TFT touch screen: Displays test values and crushing-load graphs.
Statistical evaluation: Calculates minimum, maximum, average, standard deviation and coefficient of variation.
Manual and automatic modes: Allows routine testing as well as controlled research applications.
PC connectivity: Supports data acquisition, archiving, graphical analysis and report generation.
Machine weight: Approximately 300 kg.
Product code: LT-M0100.

Description

What Is a Cold Compression Strength Test Machine?

The Cold Compression Strength Test Machine determines the compressive load required to break iron ore pellets. The system tests individual pellets under controlled loading conditions and automatically records the maximum crushing load.

The LT-M0100 is designed as a fully automatic testing system with sample feeding, compression control, test-data acquisition and statistical evaluation. It is suitable for routine quality control as well as research applications involving fired iron ore pellets.

Automatic Pellet Feeding System

The machine incorporates a continuous vibrating feeder. Pellet samples are loaded in bulk and then transferred individually to the compression area.

The system is designed for pellets approximately 8–12 mm in size. A test batch can contain between 60 and 1000 pellets, allowing laboratories to process both smaller research samples and larger routine quality-control batches.

Automatic feeding reduces the need to position every pellet manually and helps maintain a continuous testing sequence.

10 kN Controlled Compression

The loading system provides a maximum capacity of 10 kN, equivalent to approximately 1,000 kgf.

Compression speed can be selected as 5, 10, 15 or 20 mm/min. The low selected speed is maintained during the actual compression stage, while faster movement is used during approach and return to reduce total test time.

When the pellet breaks, the system records the maximum compressive load as the crushing-strength result.

Automatic Cleaning and Sample Transfer

Broken pellet fragments can interfere with subsequent measurements. Therefore, the LT-M0100 incorporates an air-cleaning system that removes remaining fragments from the testing area.

An encoder-controlled handling mechanism then transfers the tested material away from the compression zone. This automatic cycle allows consecutive pellets to be processed with minimal operator intervention.

TFT Control and Statistical Analysis

A 7-inch TFT touch-screen control unit manages the testing process and displays crushing-load data and graphs.

The control system calculates statistical values including minimum, maximum, average, standard deviation and coefficient of variation. Test information can also be transferred to a computer for archiving, graphical presentation and report preparation.

ISO 4700 and ASTM E382 Testing

The LT-M0100 supports ISO 4700, ASTM E382 and IS 8625 crushing-strength procedures.

ISO 4700:2015 specifies a method for determining the compressive load required to cause breakage of hot-bonded iron ore pellets. The current edition remains valid following its 2026 confirmation.

ASTM E382-20 covers crushing-strength determination for fired iron ore pellets and direct-reduced iron and is currently listed by ASTM as the active edition.

Overall, the LT-M0100 Cold Compression Strength Test Machine combines automatic pellet handling, controlled 10 kN loading and digital statistical analysis for efficient iron ore pellet quality control.
