Sieve Machine

Introduction of sieve machine

Sieve machine is a general-purpose vibrating screening and filtering equipment. It has good applications in powder, small particles and liquid materials. The main material is divided into SUS304 stainless steel or Q235A carbon steel. The size and diameter can be from 400 to 1500mm 1-5 layers of different models of sieves.

Dahan sieve machine can be used at the same time according to the different needs of customers from 1-5 layers. The product models are complete, which can meet various powder and particle screening requirements and liquid filtration requirements. It can also be designed as ultrasonic sieve machine, air vibration sieve machine, etc. .

Benefits of sieve machine

1. It is suitable for a wide range of materials, and can be sieved to 500 mesh or 0.028mm powder and granules, and liquid materials can be filtered to 5 microns.

2. Equipped with a bouncing ball cleaning device, which can achieve the purpose of cleaning the screen by continuously hitting the screen without blocking the screen. For viscous and electrostatic materials, the ultrasonic cleaning device can be used.

3. Fully enclosed structure, no dust spillage, improve working environment.

4. It can sieve 1 to 5 layers of screens, and can carry out 2 to 6 levels of sorting or filtering at the same time.

5. Impurities and coarse materials are automatically discharged, and continuous operation is possible.

6. The discharge port can be rotated 360°, which is easy to operate.

Working principle of sieve machine

Sieve machine uses YZUL vertical vibration motor as the excitation source. The eccentric weight on the upper and lower ends of the vibration motor converts the rotational motion into horizontal, vertical, and inclined three-dimensional motion, and transmits it to the screen surface of the rotary vibrating screen; the material passes through The feed inlet enters the equipment. According to different material screening requirements, the material passes through 1-5 layers of sieving with different mesh metal woven screens. In this process, a cleaning device is located under the screens of each layer. (Bouncing ball) Continuously hitting the screen through frequency vibration, so that the materials on the screen can be smoothly screened through the screen, and effectively solve the problem of material blockage. After the materials of different meshes pass through the screens of the corresponding meshes of each layer It is discharged at the discharge port of each layer, and finally achieves the purpose of screening and removing impurities or filtering and grading.

Structure of sieve machine

Sieve machine is mainly composed of vibrating motor, screen, net cleaning device, net frame, shock-absorbing spring, base and other parts. It is a vibrating screening equipment integrating screening and impurity removal.

1. Vibration motor: The single-flange structure of the YZUL series vertical vibration motor is adopted, which is convenient for installation and maintenance, which reduces the weight of the host and reduces the cost of the host, so that the host can handle more materials.

2. Screen: Suitable meshes can be selected according to the screening requirements. There are three materials: carbon steel, stainless steel and nylon screens.

3. Cleaning device: rubber balls or silicone balls are commonly used. Rubber balls are mainly used in occasions where the environmental sanitation requirements of materials are not very strict, and the cost is also low. Silicone balls have good elasticity and no pollution. They are mainly used in food, medicine and other industries, and the cost is relatively high.

4. Seals: Prevent the leakage of raw material fluids or solid particles from adjacent joint surfaces, prevent foreign impurities such as dust and moisture from intruding into the internal parts of the machine and equipment, and reduce the destructive force of the vibrating screen on the screen frame during vibration.

5. Shock-absorbing spring: a mechanical part that uses elasticity to work, connects the screen body and the base, acts as a buffer during the vibrating screen's working process, isolates noise, and prolongs the service life of the machine.
