Graphite Powder Sieving Machine

Introduction of graphite powder sieving machine

Graphite powder sieving machine is specially developed to solve the problem of graphite powder sieving. Graphite powder has a lighter specific gravity and a fine particle size of less than 90 to 20 microns. It is easy to clump and has good fluidity. Ordinary sieving machine will have material agglomeration and leakage during the screening process, which will cause serious blockage. The ultrasonic screening system of graphite powder sieving machine converts 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz. The high-frequency electric energy is input into the ultrasonic transducer to change it into 18KHz mechanical vibration, so that the graphite powder on the screen surface is always kept in suspension, effectively solving the problem of network blocking.

Working principle of graphite powder sieving machine

Graphite powder sieving machine adds an ultrasonic device to convert 220V, 50Hz or 110V, 60Hz electric energy into 18KHz high-frequency electric energy, and input ultrasonic transducer to turn it into 18KHz mechanical vibration, so that the vibrating screen can achieve high-efficiency sieving and cleaning. The purpose of the net. A low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) is installed on the screen. The graphite powder receives huge ultrasonic acceleration, so that the graphite powder on the surface of the screen always stays in suspension, thereby inhibiting adhesion, friction, flat drop, and Wedge and other blocking factors, thereby solving the problem of graphite powder screening due to strong viscosity, high adsorption and other factors.

Application of graphite powder sieving machine

The particle size of sieved graphite graphite powder is generally within the range of 500 mesh, generally in various specifications such as 100 mesh, 120 mesh, 200 mesh, 325 mesh, etc. When the graphite powder is screened, because the graphite powder has conductivity and static electricity, it is easy to bunch up. Cause the phenomenon of blocking the network, thereby affecting the efficiency of screening. In order to solve this problem, our company has added a set of ultrasonic system to the vibrating screen, which uses ultrasonic frequency to vibrate the screen mesh, which makes the screen holes not clogged, and it is easier to screen the powder, the system increases the screening capacity by 10 times, increasing productivity while allowing separation accuracy down to 20µm (#635 mesh). Powder (300 mesh)

Benefits of graphite powder sieving machine

1. The wave band output by the digital control power supply is transmitted to the surface of the screen 360,000 times per minute through the transducer.

2. It is suitable for separating powder with 50~625 mesh sieve, decomposing adhering substances and reducing on-screen material.

3. Compared with ordinary sieving machine, the sieving accuracy can be increased by 1-70%, the sieving efficiency can be increased by 1-100%, and the output can be increased by 1-15 times.

4. With automatic cleaning function, it will not pollute the powder with auxiliary materials such as pinballs.

5. It can be used in single layer or multiple layers, and 6 different grades of graphite powder can be obtained in one operation.

Graphite powder sieving machine use and maintenance

use:

The screen should be installed correctly. The screen of this machine is installed in a cylindrical shape, and the upper and lower ends of the screen are fixed by wire ropes respectively. 810 adhesive is used for lap bonding at the screen joint, and the lap width is about 30-50mm. When fixing the wire ropes at both ends, adjust the screen mesh while tightening, so that the screen mesh is not twisted, not smashed, and evenly tensioned. When there is a mesh test sieve, first reduce the feeding amount, and gradually increase the feeding amount.

The operation and starting sequence of the airflow sieve powder unit: induced draft fan → airflow sieve → discharge auger.

The shutdown sequence is: airflow screen → induced draft fan → discharge auger.

The dust collection bag of the bag filter should be shaken in time, generally beat or shake once an hour.

maintain:

Operators should use the equipment correctly according to the requirements of the product manual, and do a good job in daily maintenance such as cleaning, lubrication, tightening and anti-corrosion of the equipment, so that the equipment is always kept clean inside and outside, with good performance, safe and reliable.

The electrical control box should be kept clean to prevent dust from falling into the control box, causing failure or short circuit of the electrical components.

The main engine, motor and fan should be overhauled once a year, and a small amount of lubricating oil should be added to remove the dust in the motor.

The vibration exciter must be repaired once or twice a year, lubricating oil should be added for each maintenance, and the connecting bolts should be tightened.

Screen replacement should follow the requirements of the first item in the operation section to ensure uniform tension. When fixing the wire ropes at both ends, adjust the screen while tightening.
