Low Temperature Water Cooled Continuous Feed Grinder Two Stage Coarse and Fine Grinding System

Product Overview

This system is a low-temperature water-cooled continuous feed grinding solution engineered for efficient size reduction of dry materials. Its core value lies in an integrated two-stage grinding process that combines coarse crushing and fine grinding within a single unit, significantly improving workflow and eliminating the need for separate pre-crushing equipment. The built-in water circulation cooling system effectively controls temperature rise during operation, preserving the chemical and physical properties of heat-sensitive substances such as herbs, food ingredients, and chemical compounds.

Ideal for a wide range of industries including pharmaceutical production, food processing, chemical manufacturing, and material science laboratories, this unit handles diverse materials—from soft botanical fibers to hard minerals. Whether you need small-batch processing for R&D or continuous operation up to 50 kg/h, its adjustable fineness settings (60 to 180 mesh) ensure consistent, repeatable results across applications. The design accommodates everything from traditional Chinese medicine roots like notoginseng and maca to grains, spices, and industrial raw materials.

Engineered with precision components such as German FALA bearings and a durable automotive-grade timing belt drive, this equipment delivers reliable, low-noise performance even under demanding production schedules. The robust construction, complemented by thoughtful safety features including chamber door micro-switches and thermal overload protection, ensures operator safety and a long service life. Users can count on stable operation at 6000 r/min and minimal maintenance requirements, making it a trusted asset in any sample preparation workflow.

Key Features

• Two-Stage Grinding Mechanism: Coarse crushing via a toothed disc followed by fine grinding with six sets of swing hammers and wear-resistant grinding tiles. This dual-action design handles large feedstocks without pre-cutting and achieves ultra-fine output in one continuous process, minimizing handling steps.
• Water Circulation Cooling: A built-in water jacket surrounding the grinding chamber, paired with pure copper cooling tubes and a 45W pump circulating up to 2500 L/h, efficiently dissipates heat. This safeguards temperature-sensitive actives such as essential oils and alkaloids from thermal degradation.
• Precision Timing Belt Drive: Employs an automotive-engine timing belt system for smooth, quiet power transmission. Compared to chain or gear drives, it reduces vibration, extends service intervals, and contributes to a lower-noise operating environment.
• German FALA Bearings: High-precision bearings support the main shaft at 6000 r/min, ensuring concentricity and long-term reliability. Their quality construction minimizes friction and maintenance downtime even under continuous use.
• Easy Screen Replacement: The pull-out inclined iron mesh screen design enables rapid access for inspection or cleaning. Tool-free removal simplifies mesh changes, allowing quick particle size adjustments between batches.
• Comprehensive Safety Features: A micro-switch on the grinding chamber door prevents motor startup when the door is open, while a thermal overload relay protects against excessive current. These redundant safety measures ensure operator protection and equipment longevity.
• Optional Mobile Platform: An available trolley base with lockable casters and a handle facilitates movement between workstations or storage areas. This flexibility supports multi-user environments, job-site demonstrations, or cleaning operations.
• Continuous Feed Capability: Unlike batch-style mills, the open feed hopper allows non-stop material introduction, maximizing productivity for medium-scale processing. Consistent feeding results in uniform particle size output and stable thermal management.
• Durable Construction: The grinding chamber and key wear parts are fabricated from abrasion-resistant materials, extending service life even when processing hard minerals or metallic compounds. Stainless steel options are available for food-grade applications upon request.
• Versatile Material Compatibility: Processes an exceptionally wide range of dry substances, including fibrous roots, brittle ores, and sticky powders. The adjustable fineness and robust design accommodate diverse industry requirements without compromising performance.
