Frequently Asked Questions about Our Agricultural Machinery

Like most mechanical equipment, the machine makes normal operating noise, but it does not have an influence on normal use or damage the working environment.

We recommend operating the machine within a temperature range of -10°C to 40°C and avoiding heavy rain, excessive dust, or flammable and explosive environments.

Yes. It can process wheat, maize, sorghum, millet, and other grains by replacing the appropriate screens and adjusting the roller gap.

Small machines are lightweight and easy to move without wheels. Medium and large machines are equipped with universal wheels for convenient mobility.

Yes. Although the machine is lubricated before shipment, regular lubrication is also recommended for long-distance transportation and long-term storage.

It depends.
Light rain: Short-term operation is acceptable with proper electrical protection
Heavy rain or thunderstorms: Operation is strictly prohibited
Long-term outdoor use: A rain shelter is required to prevent erosion or electrical faults.

Yes. The housing is made of painted carbon steel or stainless steel to provide corrosion resistance. Regular cleaning is also recommended in humid or saline environments.

Overheating is unlikely with proper maintenance. Avoid operating at full load in high-temperature environments for extended periods.

Yes. Ensure adequate ventilation and never operate in enclosed spaces.

Yes. We are supported by an experienced development and production team and offer OEM/ODM customization for bulk orders or special requirements, including specific power, specific size, or integrated functions. Please contact our sales manager for further information.

Freight is calculated based on shipment volume or weight, depending on the destination port and shipping method. Standard delivery is to the designated port or domestic logistics point.

Yes. One set of basic spare parts (screens, belts, etc.) is included. Additional parts can be purchased separately.

Small machines are packed in cartons with foam protection for partial shipment. Large machines are packed in wooden crates to protect against pressure and impact.

Yes. Custom logos, packaging labels and OEM branding are available (MOQ required).

Yes. Mixed-model orders are supported for one-stop purchasing.

There is no minimum order quantity. Orders can be placed starting from one unit. Larger orders may qualify for better pricing.

According to international trade practices, duties and taxes are borne by the buyer

Yes. Orders of 5 units or more qualify for discounts. Further details can be discussed based on the order amount and machine type.

Payment in local currencies may be accepted.

Yes. The order tracking link will be provided after payment, showing the production, delivery, and shipping status. Real-time updates are also available upon request.

Yes. Complete OEM services are available from design to branding. Please get in touch with us for further information.

The whole machine enjoys a 1-year warranty. Consumable parts such as screens, belts, and blades are not covered within warranty.

Original spare parts can be purchased directly from us and long-term spare parts supply is available. We can also provide size specifications for local sourcing.

Yes. Factory repair is supported. Round-trip shipping costs are borne by the customer and repair costs depend on the actual condition.

Yes. A red emergency stop button is installed in a clearly visible position on the control panel.

We offer effective and professional technical support to ensure your questions are worked out. Over 90% of common issues can be solved within 1 hour through remote video guidance.

Yes. Consumable parts (blades, screens, belts, etc.) are designed for quick replacement without dismantling the whole machine. Please refer to the instructions during replacement.

Cut off the power immediately and stop using the machine. Check for damaged or damp wiring. If the issue persists, contact a professional electrician or our support team.

Within the 1-year warranty period, motor failure not caused deliberately

will be replaced free of charge.

Stop the machine immediately and check for foreign objects or loose parts. If the issue persists, contact our technical support.

Please contact us after receiving the machine and then installation videos and guidance will be provided.

Check power supply, belt tension, and lubrication. Run the machine idle for 5 to 10 minutes to ensure there is no abnormal noise or vibration before feeding materials.

Follow the principle “loose first, then tight.” Start with a wider gap for faster milling, which may produce more bran. Then gradually tighten the valve until the rice surface becomes smooth enough and the broken rate is acceptable (usually <5%). The optimal setting depends on the rice variety and moisture content.

The optimal rate allows smooth output without blockage. Adjust the feed gate or variable speed controller to avoid excessive feeding.

Check protective covers, safety locks, electrical safety, belt and blade fastening.

Inspect the machine before starting. Keep your hands away from moving parts during feeding to avoid accidents and feed materials evenly.

Yes. Different grains have different hardness and require screen replacements and feeding adjustments.

Stop feeding first and let the machine run idle for 1 to 2 minutes to clear the remaining materials before turning off the power.

Press the middle of the belt. A deflection of 1 to 2cm is ideal. A belt that is too loose may slip or lose rotation, while excessive tension may aggravate bearing wear.

Adjust the fan air valve and screen size together to achieve optimal separation. A larger fan air valve increases airflow and improves bran removal, while the screen size determines the rice output size.
