Overview
The laboratory manual lift basket sand mill is an economical wet dispersion grinding equipment, suitable for scientific research institutions and enterprises and institutions. The equipment can operate stably for a long time, with low noise, and complete two processes of dispersion and grinding at the same time, which can effectively reduce the fineness of medium and low viscosity materials in a short time.
Features
1. High grinding efficiency, good product fineness: Rotation speed up to 3000rpm, arc impeller kinetic energy drive, zirconia lever makes the grinding medium irregular movement, fineness can reach 10um or less, liquid-liquid dispersion grinding can reach sub-micron or nano level; separation plate adopts CNC control numerical processing of whole material, long life without blockage.
2. Easy to operate, easy to clean: its own energy-saving inverter to control the start and speed; configuration of manual or electric lifting device; cylinder and lid are relatively closed, less solvent volatilization; unique design of grinding cavity, direct solvent circulation cleaning; stainless steel design of the whole machine, beautiful and easy to clean; long time timing shutdown can be set for grinding.
3. Small temperature rise, stable product: Mixing Tank with double-decked chill down jacket, mirror polishing treatment, water chill down during operation, conventional temperature rise is less than 10 °; multiple barrels can be customized for easy use.
4. Strong non-standard: lifting form can be customized manual or electric; non-standard customized explosion-proof type; material contact parts can be made of SS304 or SS316L material; support high temperature, high voltage, flammable, explosive, corrosion and other working conditions tailor-made.
Principle
When the laboratory manual lift basket sand mill motor is running, it drives the dial rod and dispersion disc to swirl/spin at high speed, so that the ground body generates negative pressure, which prompts the material to be forcibly sucked into the grinding cavity, and the high-density zirconia beads continue to collide and rub, so that the material particle size becomes smaller and the fineness is reduced.
Applications
Interior-wall latex paint, industrial paint, wood paint, various colorants, water-based oily inks, pesticide suspensions
Steps
1. Start the device and adjust the speed: Use the built-in frequency converter to control the start and Rotation speed.
2. Lifting operation: Select the manual or electric lifting device according to the configuration.
3. Material handling: The material collides and rubs with zirconia beads in the grinding cavity.
4. Chill down: Water chilling down Mixing Tank to control temperature rise.
5. Timing setting: According to the process setting, the grinding time is regularly stopped.
6. Cleaning and maintenance: Use solvent circulation to clean the grinding chamber and keep the equipment clean.
Notice
• Material viscosity should be controlled at ≤ 5000 cps (mPas).
• Ensure that the chilled down system works properly to control the temperature rise when the equipment is running.
• Use direct solvent circulation when cleaning to avoid clogging.
• When customizing non-standard equipment, it is necessary to provide detailed data on high temperature, high voltage, flammable, explosive, corrosion and other working conditions.
• Regularly check the abrasion of the grinding medium (zirconia beads) and replace it in time.
