01 Different Screening
The trommel screen screens by vibration force generated by vibration motor, which belongs to vibrating screen, commonly used mining vibrating screen has a circular vibrating screen, linear screen, etc.
The trommel screen is another form of screening and the equipment will not appear vibration in the screening process but the general motor and reducer opportunity through the bearing to drive the drum to rotate, material in the drum due to the rotation of the drum from high to low through the screen, is screened successfully, which belongs to rolling screening.
02 Different Shape and Structure
The two are so different in appearance that it's easy to tell them apart.
Trommel screen is a cylinder, cylinder appearance with a layer or multilayer, or several sections of the screen to increase screening specifications. The drum screen volume is generally larger, mainly composed of motor, reducer, drum device, screen, frame, seal cover, inlet, and outlet composition, drum device, which are added to prevent deformation of drum screen.
The vibrating screen is mainly composed of a screen box, screen frame, screen, vibration motor, motor pedestal, damping spring, and bracket.
linear vibrating screen is equipped with two vibration motors, which can be divided into several layers at the bottom of the equipment.
Trommel screen is also known as a single shaft vibrating screen whose support has two kinds of suspension support and seat support.
Trommel screen and vibratory separator are generally composed of the prepared screen or punching screen with a 6mm-8mm screen size. 03 Different working principles
• Trommel screen
The roller device is tilted on the frame. The motor is connected with the drum device by a reducer through a coupling and drives the drum device to rotate around its axis. After the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is flipped and rolled, qualified material (under the screen product) discharged by the discharge port at the bottom of the rear end of the drum, unqualified material (on the screen product) discharged by the discharge port at the tail of the drum.
