Question 1

What materials are suitable for mixing with a conical powder mixer?

Accepted Answer

Suitable for powders and particles (such as chemical raw materials, medicines, food additives, battery materials, etc.), especially for materials with large density differences, fragile or slightly sticky. Not applicable: strong viscous pastes, high-humidity agglomerated materials (special design required).

Question 2

How long does the mixing time usually take?

Accepted Answer

Conventional materials are about 5-20 minutes, which needs to be determined through experiments. High uniformity requirements (such as the pharmaceutical industry) may be extended to 30 minutes.

Question 3

What is the maximum load capacity of the equipment?

Accepted Answer

The recommended load capacity is 30%-70% of the container volume (overloading will cause uneven mixing).

Question 4

How to choose a single or double spiral model?

Accepted Answer

Double spiral: suitable for materials with high uniformity and large density differences (such as lithium battery materials, medicines). Single spiral: suitable for ordinary mixing needs, lower cost.

Question 5

Is an explosion-proof design required?

Accepted Answer

If flammable and explosive dust (such as metal powder, certain chemicals) is mixed, it is necessary to select an explosion-proof motor + static elimination device, and ensure that the equipment is grounded.

Question 6

How to choose the material?

Accepted Answer

Stainless steel (304/316L): Food, pharmaceutical industry (in compliance with GMP standards). Carbon steel + coating: General chemical, metallurgical industry (select carbon steel lining plastic when corrosion protection is required).

Question 7

What should I do if there is a lot of material residue after mixing?

Accepted Answer

Check whether the gap between the spiral blade and the bottom of the cone is too large, or whether the bottom valve is not sealed tightly. Polyurethane scrapers can be installed or the discharge port design can be adjusted.

Question 8

What may be the cause of abnormally high noise during operation?

Accepted Answer

Common causes: Bearing wear (need to be replaced). Friction between the spiral blade and the cylinder wall (adjust the installation position). Metal foreign matter is mixed in the material (stop the machine for investigation).

Question 9

Can the material be heated or cooled during mixing?

Accepted Answer

Optional jacket design, through steam/thermal oil heating or cold water circulation temperature control, suitable for scenes that require dry or temperature-sensitive materials.

Question 10

How often do you need to lubricate the equipment?

Accepted Answer

Grease the bearings and gears every 3-6 months (refer to the manufacturer's manual for details). The cycle needs to be shortened for high-frequency use or high-temperature environments.

Question 11

How to clean the inside of the equipment?

Accepted Answer

Dry cleaning: Use a soft brush or compressed air to clean the residue. Wet cleaning: Some models support CIP (cleaning in place system), directly pass the cleaning agent to rinse.

Question 12

What should I do if the spiral blade is severely worn?

Accepted Answer

Check the blade thickness regularly, and replace it if the wear exceeds 30%. In high-wear scenes, wear-resistant alloy blades or tungsten carbide coatings can be selected.

Question 13

Possible reasons for uneven mixing?

Accepted Answer

The material properties are too different (such as density, particle size). The loading capacity exceeds the recommended range. The speed setting is unreasonable (the rotation/revolution speed needs to be adjusted).

Question 14

What should I do if the equipment does not rotate after starting?

Accepted Answer

Check whether the power supply is normal. Check whether the motor overload protection is triggered (may be caused by material jam). Contact the manufacturer to check the reducer or transmission parts.

Question 15

How to deal with the blockage of the discharge port?

Accepted Answer

Use a soft stick to clear it after stopping to avoid metal tools scratching the inner wall. For sticky materials, anti-stick coating can be sprayed on the inner wall of the discharge valve in advance.
