Product Overview
This high-performance disc pulverizer is engineered specifically for batch-type and continuous fine grinding of medium-hard, hard, brittle, and tough raw materials. Designed to bridge the gap between primary crushing and analytical fineness, the equipment utilizes extreme compressive and frictional shearing forces generated between one stationary and one motor-driven rotating disc. It delivers dependable particle size reduction for laboratory testing and industrial quality control environments requiring reproducible results.
Targeted primarily at metallurgy, mining, geological prospecting, building materials, ceramics, and chemical synthesis laboratories, this system enables operators to rapidly prepare representative sample powders from coarse inputs. Whether processing mining ores, geological drill cores, industrial slag, or advanced technical ceramics, the machine efficiently handles demanding materials, significantly minimizing sample preparation cycle times while eliminating reliance on external testing services.
Built on a rigid cast base with precision-machined spindle assemblies and heavy-duty wear-resistant disc alloys, this grinding unit demonstrates unmatched operational stability and durability under demanding testing conditions. Its fully enclosed grinding chamber ensures clean laboratory operation, prevents airborne particulate contamination, and preserves sample purity throughout extended daily operation.
Key Features
- Dual Disc Shearing Mechanism: Employs a precision-aligned dynamic disc opposing a stationary disc, generating intense friction and compressive stress to pulverize tough, brittle mineral and material matrices rapidly.
- Dual Handwheel Gap Calibration: Features an intuitive dual-wheel adjustment mechanism where a primary lock handwheel and secondary micro-adjustment lead screw move the drive spindle axially, delivering rapid, reproducible grinding gap control down to 0.15 mm.
- Heavy-Duty V-Belt Transmission: Delivers smooth, vibration-damped power transfer from a high-efficiency 1.1 kW industrial motor to the grinding spindle, protecting the motor against torque spikes while operating continuously at 780 rpm.
- Robust Sealed Grinding Chamber: Combines a heavy-duty structural body, sealed front end cover, and secure upper access hatch to fully contain dust, maintain sample integrity, and ensure clean laboratory operation.
- Versatile Gravity-Fed Feed Hopper: Features an optimized intake throat geometry that ensures uniform, uninterrupted raw material feed directly into the central eye of the grinding discs without material bridging.
- Rapid Sample Recovery System: Discharges ground particulates directly from the peripheral disc perimeter into an integrated bottom collection bin, ensuring near-total sample recovery and simplified operator workflow.
- Industrial Cast Base Stability: Built on an ultra-rigid cast iron foundation that eliminates harmonic vibration, stabilizes disc parallelism during heavy crushing loads, and extends overall bearing service life.
- Quick-Access Chamber Design: Allows laboratory technicians to swiftly unlatch the front end cover for rapid internal inspection, thorough disc cleaning between batches, and complete cross-contamination prevention.
