How to Choose a Used Combined Rice Mill? Key Points for Inspection, Price Negotiation and Maintenance

The combined rice mill is a common piece of primary agricultural product processing machinery in rural areas. It can complete the processes of hulling, whitening and bran-rice separation in one pass, handling large volumes while saving labor and time. Many growers and small rice processing operations consider buying used equipment to reduce upfront investment, but the used agricultural machinery market is full of pitfalls, so you must do your homework thoroughly before buying.

Before Buying a Used Rice Mill, First See the True Condition of the Equipment

First, look at the wearing parts. The emery roller, rice knife and screen plate of a rice mill are consumable parts, and excessive wear will lead to more broken rice and a lower rice yield. You can ask the seller to open it up for inspection on the spot; if the wearing parts are close to the end of their service life, factor the replacement cost into the negotiation.

Second, listen to the sound and feel the temperature. During a no-load test run, pay attention to whether the motor and bearings make abnormal noises and whether vibration is excessive; after running for a while, touch the bearing housing - if it is too hot to touch, the bearings may already be damaged. Third, check the nameplate and production information to confirm the model, power and date of manufacture, and verify that the motor power matches the nameplate to avoid being fooled by a machine assembled from mismatched parts.

If conditions permit, bring some paddy rice and test-mill it on site to see the broken rice rate, whiteness and rice yield of the finished rice. This is the best way to reflect the equipment's true performance.

Points to Note in the Transaction Process

Before negotiating the price, first learn the market price of a new machine of the same model. The used price is usually much lower, but equipment priced too low often has a history of major repairs or questionable origins, so be especially cautious. During the transaction, verify the source of the equipment and preferably sign a simple purchase agreement stating the equipment's condition and the payment method. If the equipment has previously received an agricultural machinery purchase subsidy, the relevant procedures must be handled in accordance with the regulations of the local agricultural machinery authority, and the specific requirements are subject to local announcements.

In addition, take transport and installation costs into account. Rice mills come with a matching motor and base, and freight to remote areas is not cheap. You can raise this during price negotiations and ask the seller to offer an appropriate discount or take responsibility for delivery.

Maintenance Advice After Purchase

After getting your hands on used equipment, it is advisable to first tighten all screws, clean out the residual bran powder inside the machine, check the belt tension and add grease to the bearings. In daily use, run the machine briefly without load before each start-up to check for jamming; after each session, promptly clean out bran and debris to prevent moisture clumping, mold and rodents chewing the wires. Replace wearing parts promptly according to their wear condition - do not wait until the rice yield drops noticeably, as that wastes both grain and money.

As long as you choose carefully and maintain it diligently, a well-functioning used combined rice mill can fully meet the daily needs of a family farm or small processing operation, and the return on investment is still quite considerable.
