Lab scale co-mill ( Model: WSZLJ-100 )

The machine uses the high-speed relative movement between the rotor and the screen to quickly mill the lump-shaped
materials under the rollers and pass through the sieve holes to form granules. The finished granules are discharged
instantaneously. The frequency conversion speed regulation is adopted, and the spindle speed is adjustable. , The range is wide,
the lower drive is adopted, and the feeding is smooth. Wildely used in pharmaceutical,food,chemical and other industries.It is an
ideal equipment for laboratory process exploration and practical teaching.

Model: WSZLJ-100

It is suitable for the mill of materials ≥10g per batch.
It adopts touch screen + service motor control, which is convenient to control and can precisely control the speed.
Quick-installation connection, simple, fast and easy to clean.

CONCEPTION

The calibration Of the granulated material by means Of the conic screen mill is got when the granule goes into the impact and cutting chamber, and an impeller – which is turning round at high speed — impacts on the material, shatters it and impels it tangentially towards the holes of a selector screen or cone (see figure 1)
The conic calibrator CPS Developer has been manufactured with the purpose of offering higher calibration versatility, in such a way that a wide variety of materials could be calibrated with the highest accuracy required.

CPS versatility is due to the possibility 0/5 controllable variable combination, in a unique configuration for each type

Of material to be calibrated:
1. Impeller speed
2. Impeller shape
3. Size and shape of the selector cone boles
4. Distance between the impeller wall and the selector cone wall
5. The total area of holes in the selector cone

Each of these 5 variables will affect on the features of the obtained calibrated material in different ways.

Keeping 4 constants of the 5 variables and changing the fifth one, you could see a change in the features of the obtained calibration in accordance with the following general rules:

• The impeller speed increase or reduction will reduce or increase the medium size of the obtained calibration, respectively.
• The flat side face impeller shall produce finer granules than the round face impeller.
• The cone hole size and shape shall determine the particle medium size and its shape.
• The impeller— cone distance shall affect the medium size.
• The total biggest opening area of the cone shall give the lower proportion of fine granules.

SCALE UP

The obtained calibration quality with the CPS Developer mill can be reproduced in CPS mills of a productive scale by means of two alternative scaling factors:

1. Tip Speed
2. Specific Energy Consumption (ESPEC)

Due to a wide range of turning speed, CPS Developer reaches to tip speeds similar to the ones of the production mills.

Optionally, CPS Developer can be equipped with a device that measures the power consumption; this value is used to calculate the ESPEC value.
