QM-3SP04 Planetary Ball Mill (gear type)

Application:
QM series planetary ball mill is the requisite equipment for mixing, fine grinding, small sample preparing, new product development and small volume high-tech material production. The product has small volume, complete function, high efficiency and low noise. It is the ideal facility to acquire research samples for research institutes, universities as well as enterprise laboratories (can acquire four samples in one experiment). If mated with vacuum ball milling tanks, it can grind samples in vacuum status. The product is extensively applied to in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry Medicine, Environmental Protection etc.

QM series planetary ball mill has four ball grinding tanks installed on one turnplate. When the turnplate rotates, the tank axis makes planetary movements and the balls in the tanks grinds and mixes samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of grinded products can be as small as 0.1 micron (i.e.) 1.0×10-4mm)
If equipped with the air cooling plant, the machine can be upgraded into a low temperature planetary ball mill. For further information on the low temperature planetary ball mill, please see the brief introduction to QM-DY,QM-DK low temperature planetary ball mills.

Type:

Technical parameters:
Drive Mode: gear drive and belt drive
Operation Mode: two or four grinding tanks working together
Maximum Loading Capacity: 2/3 of the capacity of milling tank
Feeding Granularity: soil material ≤10mm, other materials ≤3mm
Output Granularity: Minimum 0.1um
Rotation Speed: 0.4L:0~600rounds/min;

or negative revolving
Max. continuous operating time (full-load): 72 hours

Advantage:
1. High uniformity
2.Excellent repeatability
3.Convenient operation: belt replacement is not needed;
Gear drive mode offers an effective solutions to problems caused by belt drive mode, such as belt creep, and belt abrasion.

Criterions for evaluation:
1. Rotational speed Studies have proved that the rotational speed is the most important criterion of the planetary ball mill. In principle, the higher the rotational speed is, the better the milling performance is.
2. Maximum continuous operating time The planetary ball mill is used for making sub-micron or milli-micron materials, frequently requiring the maximum continuous operating time (at full load) being 50 hours or above, and the technical conditions such as the rotational speed not changing.
3. Uniformity A gear-driven ball mill can make materials in two or even four tanks uniform perfectly, but a belt-driven ball mill cannot.
4. Repetitiveness A gear-driven ball mill can make the same materials processed by the same technique repetitive perfectly, but a belt-driven ball mill cannot.
5. Noise The noise of belt-driven ball mill is 66dB and that of gear-driven ball mill is 68dB at no load; and the noise of the two ball mills at full load is 75dB.
6. Rational speed ratio: The rational speed ratio is very much related to the rational speed, the milling time and etc. Tests prove that the rotational speed ratios 1:2 (≤4L) and 1:1.5(≥12L) are the best ones.

Features: 
1. Gear-drive guarantees high uniformity and repeatability of experiments;
2. Fast rotational speed, high efficiency and fine granularity;
3. Four samples with different sizes and materials in one experiment available;
4. Stepless speed regulation; ideal rotary speed selection according to experimental results;
5. Timed powering-off, positive and negative revolving if required;
6. It features low center of gravity, good rigidity, compact structure, safety and reliable operation, low noise, no pollution, and small wear etc.

Standard configuration:
Main machine, power supply controller
