Weighing Large Rocks for Grading Tests

In this technique, a digital weighing scale measures the weight of each rock in a single sample. An excavator lifts the rocks to ensure precise measurements, enabling us to conduct grading tests using the weight method.

Aggregate Sampling from Conveyor Belt

This sampling method captures the full range of material sizes— from fines to oversize—directly from the conveyor belt. It's essential for accurate analysis, ensuring that the entire mix is properly graded and meets quality standards

Manual Sorting of Rocks by Size Using Steel Plates

In this process, rocks are manually sorted using steel plates to separate them according to size, ensuring they meet the precise specifications set by our customers. This hands-on approach guarantees quality and consistency for each project

Summary of Testing Purpose

In the end, the main goal of these tests is to understand exactly what products are contained within the stockpile or the output from production. The samples we take need to accurately represent the materials inside the stockpile, allowing us to control the production process effectively. This means we can determine whether we need larger rocks or finer aggregates. Ultimately, these tests support both the quarry and the client. They help the quarry produce the correct materials as requested, ensuring that clients are satisfied because the rocks delivered meet the specified designs.

Shape Factor Test

This test helps us estimate the relationship between bulk volume and metric tons, providing a useful value for calculating material in cubic meters. While the test involves precision, the result gives us practical measurements for everyday use in project planning

Size Matters, but So Does Rock Profile

In addition to size, the profile of each rock plays a crucial role. Rocks can vary greatly in terms of soundness and porosity, which affect their strength and durability. The color—whether black or white—also signifies different mineral compositions. Some rocks are brittle and crack easily, while others are more solid and robust. Furthermore, the source of rock formation can differ, with some being homogenous and others heterogenous in structure. These variations all influence the suitability of the rock for specific construction projects and must be considered during production and grading.

Alternative Sieve Analysis for Armour Rock

This method showcases the process of sorting armour rock based on size using a manual sieve setup. By separating the material through various mesh sizes, we ensure consistent grading and quality control for large-scale projects

Sorting Rocks by Size According to Customer Specifications

Each pile of rocks has been carefully separated based on size to meet the exact specifications provided by the customer, ensuring the material is ready for use in their specific projects
