HIGH CAPACITY ROTARY GOLD TROMMEL SCREEN SIEVE
Working principle
The trommel screen is mainly composed of a motor, a reducer, a trommel device, a frame, a sealing cover,
and an inlet and outlet. The roller unit is mounted on the frame at an angle. The motor is connected with
the drum device through the reducer through the coupling, and drives the inclination and rotation of the
drum device, so that the material on the screen surface is turned over and rolled, so that the qualified
material (product under the screen) is discharged through the outer screen of the drum. Unqualified
materials (on-screen products) are discharged through the end of the drum. Due to the turning and
rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the
screen hole from being blocked.
Classification of trommel screen:
1. Classify according to whether there is a central axis structure
Shafted trommel screen can screen granular, powder, agglomerated materials, and shaftless trommel
screen adopts shaftless design, which can screen and Screening, the yield will be increased by 20%
compared with the shaft.
2. Classification according to the shape and structure
It can be divided into closed type and open type (cage type trommel screen). The closed type trommel
screen can protect the cleanliness of the surrounding environment, and can also protect the screened
materials from the influence of the external environment, which meets the requirements of the
environmental protection industry.
Product advantages
● The screen hole of the trommel screen is not easy to be blocked;
● Balanced operation and low noise;
● Simple structure, easy maintenance;
● High reliability of the whole machine, less one-time investment;
● Adopt special screen, which has high screening efficiency and long service life.

Technical parameters
Note: 1. The external dimensions are calculated according to the length of the cylinder; 2. The
processing capacity is calculated according to the large aperture; 3. The angle of inclination and
the length of each section are different depending on the material; 4. The quality is calculated
according to the length of the cylinder and the woven mesh is used 5. The proportion of large
pieces of material shall not exceed 10%
