Product Overview
The Kintek Solution KT-EP Jaw Crusher is a high-performance, heavy-duty laboratory instrument designed for the rapid and gentle crushing of varying material types. Engineered for high efficiency, precision, and zero contamination, the KT-EP acts as the ideal pre-crushing solution for preparing samples for analysis.
Capable of reducing 90mm feed sizes down to <2mm in a single pass, the KT-EP is essential for laboratories dealing with geology, metallurgy, building materials, and chemical analysis. Its unique design features a complete non-magnetic stainless steel housing and specialized jaw options (Tungsten Carbide/Zirconia), ensuring maximum sample purity—crucial for trace analysis and eliminating iron pollution.
Key Features & Benefits
🛡️ Superior Contamination Control
- Zero-Iron Contamination: The instrument body, fixed jaw, and moving jaw brackets are constructed from SUS304 non-magnetic stainless steel. This prevents rust, paint chips, or magnetic adsorption from polluting mineral samples.
- High-Purity Jaw Options: For analytical grade purity, the crushing cavity can be equipped with Tungsten Carbide or Zirconia jaw plates, effectively eliminating metal abrasion contamination.
⚙️ Precision & Performance
- High Throughput: Powered by a robust 1.1 kW motor, the KT-EP delivers a continuous crushing capacity of up to 300 kg/h.
- Adjustable Fineness: Features a stepless gap width adjustment (0–30 mm) via an ergonomic handwheel with a scale display, allowing for reproducible particle sizing.
- Wide Applicability: Effectively handles medium-hard, hard, and brittle samples with a reduction ratio that prepares samples perfectly for subsequent fine grinding (e.g., in a ball mill).
👷 Operational Safety & Design
- User-Friendly Design: Features a flip-top feed hopper for easy cleaning and a removable fixed jaw arm for quick maintenance.
- Full Protection: Equipped with motor and belt pulley protection covers. The unit boasts an IP65 protection class, ensuring the internal mechanics are dust-tight and protected against water jets.
- Mobility: Comes standard with a sturdy, mobile base stand featuring universal locking wheels for easy laboratory positioning.
Working Principle
The KT-EP Jaw Crusher operates on the principle of pressure and friction. The sample enters the grinding chamber through a splash-back-proof hopper. The crushing takes place in the wedge-shaped area between the fixed crushing arm and the moving crushing arm driven by an eccentric drive shaft.
The elliptical motion of the moving jaw crushes the sample against the fixed jaw. As soon as the sample is crushed smaller than the set discharge gap width, it falls into a removable collection drawer under gravity.
Typical Applications
The KT-EP is versatile and suitable for a wide range of industries:
- Mining & Geology: Ores, coal, granite, basalt, quartz.
- Ceramics & Glass: Clinker, glass, porcelain, chamotte.
- Construction: Cement, concrete, slag, construction rubble.
- Metallurgy: Alloys, silicon, iron ore, coke.
