Laboratory Mini Jaw Crusher for Ore Coal Mineral Sample Preparation

Product Overview

This laboratory mini jaw crusher is an essential primary crushing solution engineered for high-efficiency size reduction of brittle bulk samples. Designed specifically for analytical testing environments, quality control laboratories, and pilot plants, the equipment processes a wide spectrum of hard and medium-hard materials including coal, gangue, metallurgical coke, limestone, pyrite, and geological ores. By reducing coarse raw inputs into uniform fine fractions, this system creates optimal conditions for downstream pulverizing, milling, and chemical composition analysis.

Operating on a proven curved squeezing and kneading principle, the machine utilizes dual opposing jaw plates to fracture feed materials cleanly and efficiently. The mechanical action exerts immense compressive force, breaking down brittle solids into predominantly flaked and angular particles. To maintain steady throughput and prevent material bridge formation within the feed chamber, feed material moisture levels should be maintained at or below 8%, ensuring uninterrupted discharge during high-frequency crushing cycles.

To accommodate diverse sample hardness profiles and prevent cross-contamination, the unit features interchangeable jaw plate metallurgy options including white cast iron, high manganese steel, and specialty alloys. Combined with an enclosed structural housing that minimizes ambient dust release and a simple discharge gap adjustment mechanism, this equipment provides research and testing laboratories with a dependable, clean, and highly repeatable sample preparation system.
