Industrial Laboratory Jaw Crusher for Medium and Fine Raw Material Sample Preparation Crushing

Product Overview

This laboratory jaw crusher is an industrial-grade size reduction machine designed for medium and fine crushing of bulk raw materials. Utilizing an optimized eccentric dynamic squeeze mechanism, the equipment delivers powerful, continuous compressive force to break down hard, brittle, and aggregate materials with compressive strengths up to 100 MPa. It is engineered to bridge the gap between primary bulk receiving and fine analytical milling, ensuring consistent sample preparation in pilot plants, commercial laboratories, and quality control departments.

Built for demanding processing environments, this unit is widely utilized across geology, metallurgy, coal mining, building materials, and chemical testing sectors. The system reliably processes a broad range of challenging feedstocks—including coal, gangue, metallurgical coke, limestone, pyrite, and construction aggregates. Its heavy-duty design facilitates high-throughput batch or continuous operations while maintaining strict sample integrity and uniform particle size distribution.

Engineered for structural durability and operational consistency, the crusher integrates a robust 15 kW high-torque drive mechanism and a generous 250 × 400 mm feed throat. With multiple specialized jaw plate metallurgical options and an easily adjustable discharge opening, this unit delivers exceptional mechanical reliability, minimal downtime, and long-term wear resistance under continuous laboratory and small-scale production demands.

Key Features

• Dynamic Kinematic Squeezing Action: The mechanical motion employs an eccentric reciprocating compression stroke that applies continuous, high-force dynamic pressure directly across the jaw cavity, pulverizing bulk feeds efficiently while preventing material bridging and operational stalling.
• Substantial Processing Capacity: Delivering high-efficiency throughput rates ranging between 5 and 16 metric tons per hour, this machine accommodates demanding test schedules and pilot-scale sample runs without sacrificing size reduction consistency.
• Large Feed Throat Acceptance: Featuring an expansive 250 × 400 mm inlet aperture, the assembly accommodates large aggregate lumps and coarse core samples up to 220 mm in diameter, significantly minimizing pre-crushing labor and preparation time.
• Continuously Adjustable Discharge Sizing: The internal setting allows operators to adjust the closed-side discharge gap dynamically to achieve final particle outputs below 80 mm, providing flexible sizing control across various downstream assay requirements.
• Interchangeable Metallurgy Options: To match diverse material abrasiveness and prevent cross-contamination, the unit supports standard high-manganese steel jaw plates as well as specialized wear-resistant alloy, alloy tool steel, technical ceramic, and tungsten carbide configurations.
• High-Torque 15 kW Industrial Drive: Powered by a heavy-duty 380V three-phase electric motor, the drive system generates superior mechanical crushing torque capable of processing minerals and aggregates with compressive strengths reaching 100 MPa.
• Robust Structural Cast and Fabricated Frame: Engineered from reinforced industrial plate steel and heavy stress-relieved castings, the housing absorbs heavy dynamic impact vibrations, prolonging bearing life and ensuring mechanical alignment during deep-cavity crushing.
• Accessible Maintenance and Cleaning: The open cavity layout and standardized jaw retention wedges facilitate fast plate rotations, rapid chamber inspection, and thorough cleaning between sample batches to prevent sample carryover.
