SAY-4QSoil grinder and sieve

• overview：

soil grinderIt is an essential device for mixing, fine grinding, sample preparation, dispersion of nanomaterials, development of new products, and small-scale production of high-tech materials. This product has a small volume, comprehensive functions, high efficiency, and low noise. It is an ideal equipment for scientific research institutions, universities, and enterprise laboratories to obtain micro particle research samples (four samples can be obtained at the same time in each experiment). Equipped with a vacuum ball milling tank, the sample can be ground under vacuum.mainly usedGrinding soil samples, sample preparation, can be used for pre-treatment of heavy metal analysis.Widely used in geological, mineral, metallurgical, electronic, building materials, ceramics, chemical, light industry, medicine, beauty, environmental protection and other sectors.The rotational speed, alternating time between forward and reverse rotation, and total grinding time can be set according to the process requirements.

• Working principle：

Changzhou Suoao Instrument Manufacturing Co., LtdProductiveSAY-4The variable frequency planetary ball mill is equipped with four ball milling tanks on the same turntable. When the turntable rotates, the ball milling tanks revolve around the turntable axis while also rotating around their own axis, performing a planetary motion. The grinding balls in the tank collide with each other in high-speed motion, grinding and mixing samples. This product can be ground and mixed with different particle sizes and materials using both dry and wet methods. The smallest particle size of the ground product can reach 0.1 microns (i.e. 1.0 × 10mm)-4）.

For soil heavy metal analysis, four agate grinding tanks are required. The pressure of the sealed agate grinding tanks is set through a scale, and they rotate in the opposite direction around their own axis while revolving around the turntable axis. The samples in the tanks collide and rub against each other at high speed to achieve the purpose of crushing, grinding, mixing, and dispersing the samples. They can be ground dry, wet, or vacuum. Two or four grinding tanks can work simultaneously at a time.

• Technical Parameter：

• Product Features：

• Gear transmission overcomes the disadvantage of easy slippage and unstable speed of the original belt transmission;
• It not only maintains the stability of gear transmission, but also overcomes the disadvantages of easy slippage and unstable speed of the original belt transmission.;
• The ball milling jar adopts planetary motion, with high ball milling efficiency and fine particle size;
• Variable frequency control, which can select the ideal speed based on the test results;
• The frequency converter has undervoltage and overcurrent protection, which can provide necessary protection for the motor;
• The integrated system has functions of timed shutdown, automatic timed forward and reverse rotation, and can freely choose one-way, alternating, continuous, timed and non timed operation modes as needed to improve grinding efficiency;
• One experiment can simultaneously obtain four samples of different sizes and materials;
• Low center of gravity, stable performance, compact structure, easy operation, safe and reliable, low noiseNo pollution, minimal loss;
• The equipment is equipped with a safety switch, which can prevent the equipment from starting when the safety cover is opened, thus avoiding safety accidents;
• Horizontal planetary grinding machineDue to the horizontal structure of the ball mill tank, there is no fixed bottom surface during rotation, which effectively solves the problem of some materials sinking to the bottom.

Standard vibrating screen data

1、 Function and principle of vibrating screen:
The basic principle is to use the heavy hammer (uneven heavy hammer) installed at the upper and lower ends of the motor shaft to transform the rotational motion of the motor into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. If the phase angle of the upper and lower heavy hammers is changed, the direction of the raw material's movement can be altered.

2、 Motor usage instructions:
This series of motors can continuously output rated excitation force when the following conditions are met.
1. Vibration acceleration: not exceeding 7g (g: gravitational acceleration)
2. Environmental temperature: not exceeding 40 ℃
3. Altitude: not exceeding 1000m
4. Power frequency: 50Hz
5. Voltage: 220V
6. Temperature rise: less than 80K (resistance method)

3、 Use and maintenance of vibrating screen
1. This machine should be equipped with electrical protection devices.
2. During the initial operation of this machine, check the anchor bolts at least once a day to prevent loosening.
3. After running the machine for 1500 hours, the bearings should be checked and replaced immediately if there is serious damage.
4. When the machine is stopped for a long time and used again, the insulation resistance should be measured, which should be greater than 0.5 megohms for a 500 volt megohmmeter measurement.
6、 Daily maintenance of vibrating screen
1. Before startup:
(1) Check whether the coarse and fine nets are damaged
(2) Is each group of tie rings securely locked
2. At startup:
(1) Pay attention to any abnormal noise
(2) Is the current stable
(3) Is there any abnormality in the vibration
3. After use: Clean the vibrating screen after each use
regular maintenance
Regularly inspect the coarse mesh, fine mesh, and springs for fatigue and damage, and check if any parts of the machine are damaged due to vibration. Parts that require lubrication must be lubricated with oil.
