China Seed Crop Grain De-stoner Cleaning Impurities Separator De-stone Seeds and Grain Cleaner

Product Description

Product Description

The working principle of the specific gravity stone removal machine is based on the difference in specific gravity between materials and impurities, and separation is achieved through mechanical wind force and screen surface movement:

Core Principle
By utilizing the difference in specific gravity between grains (such as rice and wheat) and impurities (such as gravel and sediment), automatic grading is achieved through the combined action of inclined screening surfaces and airflow. Impurities, due to their high specific gravity, move along a specific trajectory on the sieve surface and are ultimately discharged; Light grains move in the direction of the sieve surface movement.
Key Technical Points
  • Screen movement: The screen moves back and forth along a specific trajectory (such as in an inclined direction), promoting a relative motion trend between the material and impurities.
  • Airflow assistance: By using suction or blowing airflow to act on material gaps, the specific gravity grading process is accelerated, making impurities easier to separate.
  • Grading criteria: In addition to specific gravity, the separation effect is further enhanced by utilizing the difference in suspension velocity between materials.

This device is widely used in fields such as rice processing and wheat processing, and can effectively remove impurities with high specific gravity to ensure processing accuracy.

Feature Details
Use the principle of specific gravity to separate grains or beans. Separate and remove dust and impurities, such as: branches, stones, broken beans, sand, etc. Stones can be removed from the inside of the machine. Mostly, this model is used with the entire set of equipment. For example, cleaning machine, polishing machine, magnetic de-soiler, grading machine, and it can also process the grain itself.

FAQ

Q1: What is the De-stoner Machine?

A De-stoner Machine (also called a Stone Separator) is a specialized grain and seed cleaning equipment designed to remove heavy impurities like stones, mud balls, glass pieces, and metals from agricultural products. It works based on differences in density, size, and weight between good grains/seeds and contaminants.

Q2: Are the machines directly manufactured?

Yes, they are produced by a professional manufacturer specialized in grain/seed cleaning equipment with over 20 years of production and sales experience in the industry.

Q3: What details are needed for a fast quotation?

For a fast and accurate quotation, please provide the following details:

  • Grain/Seed Type & Purpose
  • Capacity Requirements
  • Current Condition of Material (Moisture content % etc.)
  • Local operating voltage
Q4: Can one machine work on different types of seeds?

Yes. You only need to change the screen model corresponding to different seeds to achieve multiple uses of one machine. Multiple screens can be fitted on single machinery to adjust to different varieties of seeds.

Q5: What are the standard payment terms?

Accepted payment methods include T/T, L/C, Western Union, and Cash. The standard term is a 30% deposit with the purchase order, and the remaining 70% balance paid before shipment.

Q6: What after-sales service and support is available?

1. Warranty Coverage: Standard 12-month warranty covering manufacturing defects and free spare parts (e.g., screens, belts, motors) during the warranty period.

2. Technical Support: Remote assistance via phone, email, or video call for troubleshooting. On-site engineers are also available depending on location.

3. Maintenance & Parts: Preventive maintenance plans, genuine parts in stock (sieves, filters, sensors) for quick shipment, and lifetime support for obsolete parts.

4. Operator Training: Free operator training (on-site or online) along with detailed instruction manuals in multiple languages.
