Single Tank Horizontal Jar Mill for Laboratory Grinding and Mixing

Product Overview

The single tank horizontal jar mill is a high-performance laboratory instrument engineered for precise grinding and homogeneous mixing of a wide variety of materials. Utilizing a frictional processing mechanism, the mill rotates a cylindrical grinding jar on two durable polyurethane-coated rollers, creating a controlled cascading motion that reduces particle size efficiently. This robust system is ideal for processing small, medium-low hardness, brittle, dry, or low-viscosity samples, making it an essential tool for research and quality control laboratories.

This versatile unit excels in applications across material science, geology, ceramics, pigments, pharmaceuticals, and chemical industries, where achieving consistent particle size distributions from 1 to 20 µm is critical. With a jar capacity range of 250 ml to 3000 ml, it seamlessly scales from small-batch testing to pilot production. The ability to perform both dry and wet grinding, as well as milling under inert gas or vacuum conditions, ensures that even oxygen-sensitive or moisture-reactive samples can be processed without compromise.

Designed with reliability and user safety in mind, this mill integrates a powerful 250W motor, electronic roller positioning (classic or positioning type), and a comprehensive suite of safety features including overload protection, emergency stop, and a power-off memory function. The IP65-rated enclosure provides protection against dust and water jets, while CE certification confirms compliance with international safety standards. Its low-maintenance design, combined with quick roller replacement and a durable polyurethane coating, guarantees long-term, trouble-free operation in demanding lab environments.

Key Features

• Wide Jar Compatibility: The mill accommodates grinding jars from 250 ml to 3000 ml, available in materials including zirconia, tungsten carbide, agate, nylon, stainless steel, and polyurethane. This broad selection allows users to tailor jar properties—hardness, abrasion resistance, contamination risk—to precisely match the sample type, ensuring clean and consistent results across diverse applications.
• High-Speed Roller System: Twin polyurethane-coated rollers driven by a robust 250W motor achieve a maximum speed of 900 r/min, producing a vigorous yet uniform grinding motion. The carefully balanced roller assembly minimizes vibration, enabling stable operation even at full speed and contributing to extended mechanical lifespan and reduced noise.
• Flexible Grinding Modes: The equipment supports dry grinding, wet grinding, and protective atmosphere milling (inert gas or vacuum), making it adaptable to a wide spectrum of materials. This versatility is critical for processing oxygen-sensitive compounds, moisture-avoiding samples, or when contamination must be strictly controlled.
• Precision Particle Control: With an initial feed size of less than 5 mm, the mill consistently achieves output particle sizes in the range of 1 to 20 µm, depending on material properties and grinding duration. The programmable timer and variable operation modes (continuous, intermittent, alternating) allow fine-tuning of the milling process for repeatable particle size distributions.
• Intelligent Operation & Safety: An intuitive control panel offers electronic roller positioning (classic or positioning type), digital timing, and selection of grinding cycles. Safety features include emergency stop, overload and dangerous operation protection, and a power-off memory that restores settings after power loss, enabling unattended operation with confidence.
• Easy Maintenance & Durability: The electric sliding roller mechanism facilitates quick, tool-free roller changes, minimizing downtime. Integrated LED lighting and a transparent protective cover allow real-time process observation, while the IP65-rated enclosure and heat dissipation design ensure reliable operation in dusty or wet laboratory environments.
