Planetary ball mill (soil grinder) and sieve

Purpose:

The planetary ball mill (soil grinder) and sieve are essential devices for mixing, fine grinding, sample preparation, new product development, and small-scale production of high-tech materials. They have good applications in soil sample grinding, sample preparation, and pre-treatment for heavy metal analysis.

Host material:

The grinding tank material can be selected from hard steel, stainless steel, tungsten carbide, agate, sintered corundum, zirconia, and hard ceramics. For soil heavy metal analysis, four agate grinding tanks are required. The pressure of the sealed agate grinding tanks is set through a scale, and they rotate in the opposite direction around their own axis while revolving around the turntable axis. The samples in the tanks collide and rub against each other at high speed to achieve the purpose of crushing, grinding, mixing, and dispersing the samples. They can be ground dry, wet, or vacuum. Two or four grinding tanks can work simultaneously at once

Technical parameters:

(1) Voltage: 220V AC

(2) Transmission method: belt transmission, ultra quiet during operation;

(3) Working mode: Four ball milling tanks work simultaneously, with agate tanks of 250ml and 500m 1000ml optional

(4) Feed particle size: soil material ≤ 10mm, other materials ≤ 3mm

(5) Discharge particle size:ZUp to 0.1um in size

Sample size: The material and grinding medium should not exceed two-thirds of the volume

(6) Adjustable RPM (R/MIN): Revolution: 30-450 Rotation: 60-900

(7) Speed regulation method: Brand frequency converter with stepless speed regulation, speed accuracy of 0.2 revolutions per minute, automatic setting for forward and reverse rotation, and automatic shutdown.

(8) Three phase motor frequency converter controller power: 0.75KW (high-tech microcomputer chip control, with power display electronic monitoring device)

Continuous operation timing time (MIN): 1-9999

Reversing cycle (MIN): 1-9999

(9) Continuous working time (full load): 72 hours (timer 0-9999h);

(10) Ball milling working environment options: vacuum ball milling, inert gas ball milling, low-temperature ball milling, high-temperature ball milling

(11) Electric screening machine: Multi layer sieve with a diameter of 200MM.

Screening range: 20-200 mesh（Z is 20 microns small)
