Tumbler screen

Introduction of PC HAMMER crusher

The trommel screen is a widely used mechanical equipment in the separation technology, which controls the sorting of garbage by the size of the particles. The accuracy is high. The drum body of the trommel screen is generally divided into several sections, depending on the specific situation. The sieve holes are arranged from small to large and the diameter of the sieve holes on each section is the same.

In order to improve the sorting accuracy and avoid the small particles of material being screened out in the hole diameter screening section, the garbage must be fully turned in the trommel screen, and the moving speed of the garbage can not be too fast. A flexible plate is usually on the inner wall of the drum, and its function is to lift the garbage particles, so that different particle size garbage particles have the opportunity to contact the sieve holes as much possible. If it meets the requirements of the hole diameter, the particles can pass through the sieve, which can achieve the purpose of trommel screening

Working principle of hammer crusher

The drum device is installed obliquely on the frame. The motor is connected to the drum device through a coupling after passing through a reducer, the drum device to rotate around its axis. When the material enters the drum device, due to the oblique and rotating of the drum device, the material on the screen surface is over and rolled, making the qualified material (screen undersize product) discharged from the discharge port at the bottom of the rear end of the drum, and the unqualified material ( oversize product) discharged from the discharge port at the tail of the drum. Due to the turning and rolling of the material in the drum, the material jammed in the screen can be popped out, preventing the screen hole from being blocked. The principle structure of the drum sand sieve, drum screening machine and drum sieve is almost the same, but are differences in people's understanding and naming of it.
