SAY-4Soil grindingmachine

• 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-4Soil grindingThe machine 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, making 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.

• Product selection assistance：

1.Model Description:SAY-(Total volume of 4 cans)
Example:SAY-4: For the total volume1L, Can hold 4 of them0.25The volumetric ball milling jarSoil grindingmachineTherefore, the selection of equipment model should be based on the amount of material required for grinding at a time;

2. Selection of ball milling jar:

The main materials for ball milling jars include stainless steel, agate, corundum, tungsten carbide, nylon, zirconia, polytetrafluoroethylene, lining polyurethane, etc; The selection principle is that the material of the ball mill jar does not contaminate or affect the appearance of the material to be ground;

When grinding materials that are prone to oxidation and must be isolated from air, a vacuum ball mill can be used;

3. Grinding ball selection:

The main materials for grinding balls include chrome steel, stainless steel, agate, alumina, zirconia, etc; The selection principle is that the material of the grinding ball has no pollution or impact on the appearance of the material to be ground; The density and hardness of the grinding ball material must be higher than that of the grinding material; The ball milling specifications mainly include:Φ5， Φ8，Φ10，Φ15，Φ20

4. Grinding ball ratio:

The efficiency of ball milling depends on the appropriate combination of ball size, sample properties, particle size, weight, rotational speed, and operating mode. To achieve the best results, large and small balls should usually be used together. Large balls are used for balancing and crushing samples, as well as dispersing small balls, while small balls are used for mixing and grinding samples.
