Choosing an Air Screen Cleaner with Gravity Table: Application Fit and Specification Checks

Start with the material and separation problem

Choosing an air screen cleaner with gravity table should begin with the incoming material, the impurities that must be removed and the required process outcome—not with capacity alone. The confirmed product is described for grains, pulses and seeds, including sesame, soybeans, mung beans, kidney beans, chickpeas, coffee beans, peanuts and chia seeds. Its documented functions combine lifting, air separation, dust removal, screening and gravity separation in one unit.

The product is most applicable when the feed contains both light impurities and lower-quality kernels that need separation by specific gravity. The published description lists dust, leaves, fine and large impurities, as well as shriveled, sprouted, insect-damaged, moldy, smut-infected and immature kernels among the materials or defects it is intended to address.

Specification checks that affect application fit

1. Confirm the material and target defects

Ask the supplier to review a representative sample of the actual grain or seed. The confirmed product is specifically described as suitable for sesame, beans and groundnuts, while also listing a wider range of grains, pulses and seeds. Do not assume that a stated suitability list guarantees the same result for every variety, moisture condition or impurity profile.

If the main concern is light foreign material, an air-screen stage may address the requirement. If the feed also includes defective kernels with different density, the gravity function is relevant to the selection. The product description says that the gravity table removes low-quality particles such as shriveled, broken and other defective grains.

2. Check capacity against the complete cleaning line

The published specification for the Air Screen Cleaner with Gravity Table lists a capacity of 7–15 tons per hour and machine power of 12.8 kW. Its feature section separately describes production of 10–15 tons per hour for grains, while another section gives a broader throughput range of 5–15 tons per hour. These figures should therefore be confirmed for the buyer’s specific material, configuration and operating conditions rather than treated as a guaranteed output.

Capacity should also be checked against upstream feeding, downstream grading or bagging, storage and the required cleaning result. A nominal machine figure alone does not demonstrate that the complete line will operate at the desired rate.

3. Verify the cleaning stages and adjustment points

The process combines airflow, particle sieving and gravity separation. Airflow volume, screen speed, mesh size and tilt angle are adjustable. These are important checks when the buyer handles different seed sizes or changes between materials.

Ask for confirmation of:

• The supplied screen layers and available mesh sizes.
• The adjustment range for airflow, screen speed and table tilt.
• The intended settings for the buyer’s material and defect profile.
• How separated fractions are discharged and transferred to the next stage.

The product has interchangeable screens and a low-speed, non-broken elevator.

4. Consider dust control and installation format

The product integrates a cyclone dust-removal system and is suitable for standalone operation or integration into a complete production line. Buyers should confirm the required space, electrical supply, material flow, dust-discharge arrangement and interfaces with adjacent equipment.

The product is applicable when a buyer wants combined cleaning and grading functions in one machine.

For the confirmed product description and model-specific details, review the Air Screen Cleaner with Gravity Table product page.

When the product is a suitable candidate

The Air Screen Cleaner with Gravity Table is an applicable candidate when the buyer’s process requires:

• Removal of light impurities through airflow.
• Removal of large and small impurities through screening.
• Separation of defective or lower-quality kernels through gravity sorting.
• A combined unit for grains, pulses or seeds, especially the materials identified in the published description.
• Adjustable screening and separation conditions for different materials.

It is not automatically applicable when the requirement is limited to one narrow separation task, when the available capacity does not match the complete line, or when the buyer needs a documented certification, site layout, operating limit or performance guarantee that has not been supplied.

Buyer checklist before requesting a quotation

1. Identify the material, incoming impurity profile and desired separated fractions.
2. Confirm the required throughput using the actual material, not only the published range.
3. Resolve the capacity discrepancy between the listed 7–15 tons per hour and the other published ranges.
4. Request the exact screen configuration, adjustment ranges and process flow for the intended material.
5. Confirm power, dust handling, installation space and connection requirements.
6. Ask for sample-test conditions and a written definition of the expected cleaning result.
7. Obtain the operating, maintenance and safety documentation before final approval.

In short, the product is best shortlisted when the buyer needs air separation, screening and gravity separation together. A specification review based on the actual material and complete line will provide a more reliable purchasing decision than relying on a capacity or purity figure alone.
