1. PAINPOINT DRIVEN OPENING

Are inconsistent feed materials and variable target sizes causing bottlenecks in your pilot plant or laboratory? When processing representative samples for analysis, you face a critical balancing act: achieving precise particle size reduction without crosscontamination, excessive heat generation, or timeconsuming cleanup. These challenges directly impact project timelines, data accuracy, and operational budgets.

How do you ensure sample integrity for assay work when equipment retains material from previous batches?
What is the cost of delayed results due to a mill that cannot quickly adapt to different ore hardness or moisture content?
How much productivity is lost during the disassembly and cleaning required between sample batches?

A reliable bespoke harga hammer mill sample solution is engineered to address these exact operational friction points.

2. PRODUCT OVERVIEW

This equipment is a configurable laboratoryscale hammer mill designed for the controlled reduction of ore, aggregate, and industrial material samples. It provides a repeatable method to prepare representative samples for chemical analysis, mineral liberation studies, or process development.

Operational Workflow:
1. Feed Preparation: The sample (typically <25mm) is introduced via a sealed feed chute.
2. Controlled Comminution: Rotating hammers impact the material against a replaceable breaker plate within a fully enclosed chamber.
3. ize Classification: Reduced particles pass through an interchangeable screen with specific aperture sizes (e.g., 0.5mm 6mm) determining the final product top size.
4. Sample Collection: The processed material is discharged into a sealed container with minimal dust generation.
5. Changeover & Cleaning: Quickrelease clamps and toolfree screen/hammer access facilitate rapid cleaning between different sample types.

Application Scope & Limitations:
Scope: Ideal for dry batch processing of brittle to mediumhard materials in mining (core samples), construction materials testing, and industrial R&D labs.
Limitations: Not suitable for continuous hightonnage processing, highly abrasive materials without specialized liners, or sticky, highmoisture feeds that may cause screen blinding.
