Construction of Cylindrical Initial Cleaning Screen

As an efficient grain preliminary cleaning device, the ingenious construction design of the cylindrical initial cleaning screen is the key to realizing its efficient screening function. A deep understanding of the construction of the cylindrical initial cleaning screen helps us better grasp its working principle and maintenance points.

Cylinder Screen Body

Structure of Cylinder Screen Body

The cylinder screen body is the core component of the cylindrical initial cleaning screen, usually made of high-quality metal materials, with good wear resistance and corrosion resistance. It is cylindrical, with screen holes of specific sizes distributed on the surface, which are key to screening impurities.

Functional Features of Cylinder Screen Body

The cylinder screen body generates centrifugal force through rotation, causing grain to tumble inside the cylinder and come into contact with the screen holes, thereby achieving impurity separation. Its unique cylindrical shape not only improves screening efficiency but also ensures even grain distribution during the screening process.

Drive System

Motor and Transmission Device

The drive system of the cylindrical initial cleaning screen mainly includes a motor and a transmission device. The motor, as the power source, provides the power needed for the equipment to run. The transmission device usually adopts a V-belt or gear transmission to transfer the motor's rotational motion to the cylinder screen body, ensuring the cylinder runs stably at the appropriate speed.

Speed Regulation and Control

The design of the drive system allows for speed adjustment of the cylinder. By adjusting the motor speed or the transmission ratio of the transmission device, it can adapt to different grain types and screening requirements.

Feeding and Discharging System

Design and Function of Inlet

The inlet is the entry point for grain into the cylindrical initial cleaning screen, and its design directly affects the uniformity of grain feeding. A reasonable inlet design ensures grain is evenly distributed inside the cylinder screen body, avoiding local overloading or insufficient feeding.
