Product Overview
This laboratory batch ball mill is a specialized grinding system designed for the controlled pulverization of cement clinker and auxiliary raw materials. Built to prepare uniform samples for physical strength testing and chemical composition analysis, the equipment provides highly reproducible milling conditions essential for cement quality control. In addition to standard clinker testing, this unit effectively processes various medium-hard minerals, ores, and ceramic materials in research and testing environments.
Engineered for deployment in cement manufacturing plants, industrial testing laboratories, civil engineering research centers, and mining quality assurance facilities, the system bridges the gap between laboratory-scale experimentation and pilot-scale material preparation. Its closed-loop grinding environment ensures that sample loss and environmental contamination are eliminated, maintaining precise material ratios and precise particle size distributions for analytical workflows.
Constructed with heavy-gauge structural steel and premium mechanical transmission components, this mill delivers continuous operational stability under heavy grinding loads. The entire assembly is designed to withstand intense mechanical impact during extended milling cycles, offering analytical facilities a dependable, long-life solution that complies with standardized testing requirements.
Key Features
- Integrated Dual-Section Dust Containment Shell: Heavy-duty iron plate enclosure features upper and lower housing sections complete with a front-access door and bottom receiving hopper, fully sealed with felt ring shaft packing to prevent particulate emissions.
- High-Torque Gear-Reduced Transmission Drive: Driven by a reliable 1.5 kW motor paired with a precision speed-reduction gearbox, maintaining a consistent cylinder rotational speed of 48 r/min for optimal media impact energy.
- Vibration-Damping Structural Base Frame: Constructed from high-strength structural channel steel with six integrated 28 mm anchor bolt mounting holes to secure the assembly and eliminate operational drift.
- Automated Control Panel with Timing Relay: Outfitted with an intuitive push-button interface, thermal overload relays, indicator lamps, dynamic inching control for precise hatch alignment, and programmable timer relays for exact milling duration.
- Standardized Multi-Diameter Grinding Media Package: Supplied with a 100 kg optimized charge comprising graded forged steel balls (40 mm to 70 mm) and steel cylpebs (25 × 35 mm) designed for efficient impact shattering and attrition grinding.
- Rapid-Access Milling Hatch Mechanism: Securely sealed drum door allows effortless opening, rapid batch loading, thorough cleaning between runs, and direct discharge into the internal collection hopper.
- Controlled Powder Fineness Output: Capable of reducing raw feed up to 7 mm in particle size down to a uniform 80 to 150 mesh discharge powder within rapid 10 to 30 minute processing cycles.
- Robust Powder Discharge System: Features an internal discharge plate structure that facilitates fast, complete emptying of the ground material without residual cross-contamination between test runs.
