The Grain Impurity Screen is a vibratory sieving unit designed to clean seeds, wheat, nuts, corn and similar agricultural products. Raw material is fed by an elevator, light impurities and dust are removed through a double‑direction gravity catcher, and the material then passes into a vibrating sieving trunk. The trunk contains two layers of sieves; the upper layer separates coarse pieces such as wood, straw or strings that are larger than the grain, while the lower layer captures fine particles like sand or broken grain that are smaller than the grain. Vibration is generated by an engine whose angle can be adjusted, and rubber balls inside the screen provide continuous self‑cleaning during operation.
Typical screens of this type are built with a carbon‑steel frame and stainless‑steel mesh plates, offering mesh sizes from 0.2 mm to 5 mm depending on the target grain size. Vibration frequencies normally range between 30 Hz and 60 Hz and the angle of inclination is adjustable from 0 to 30 degrees, allowing operators to optimise separation efficiency. Capacity for a screen of comparable dimensions is usually between 5 t/h and 10 t/h, with a power requirement of 5 kW to 10 kW. These parameters match industry practice for medium‑scale grain cleaning lines.
Processors of cereals, feed manufacturers and grain exporters commonly install this screen on assembly lines that also include cyclone dust separators or pulse‑jet bag filters to protect the work environment. The equipment can be supplied as a stand‑alone unit or integrated into a larger grain cleaning machine, depending on the buyer’s layout. Trade conditions such as packaging, incoterms and payment methods should be confirmed directly with Yongming Machinery Manufacturing Co., Ltd. before placing an order.

Before ordering, verify the screen’s mesh size, frame material and vibration specifications against the grain type you intend to process. Request a detailed data sheet that lists the exact dimensions, weight and power requirements, and confirm that the unit complies with any relevant safety standards in your market.
Logistics for the screen typically involve a bulk shipment in a wooden crate, with incoterms such as FOB or CIF negotiated per order. Lead‑time and payment terms, including letters of credit or telegraphic transfer, must be agreed upon directly with Yongming Machinery Manufacturing Co., Ltd. to avoid misunderstandings.
Arrange a third‑party inspection at the supplier’s facility to check the mesh integrity, vibration functionality and the condition of the self‑cleaning rubber balls. Ensure that the inspection report and a conformity certificate are provided before the goods are loaded for export.
