Nano-grinding machine is the most widely adaptable, advanced and efficient grinding equipment for materials at present. The grinding chamber is the narrowest, the clearance of the pole is the smallest, and the grinding energy is the most intensive. With the combination of high-performance cooling system and automatic control system, continuous material processing can be realized, and the production efficiency can be greatly improved. Today let's look at how to control the grinding efficiency of the grinder in actual production.
The selection of grinding and dispersing equipment is the premise of realizing high efficiency of grinding. There are two original prototypes of grinding machine: traditional horizontal rolling ball mill and vertical agitating ball mill. Both grinding and dispersing equipment are widely used. But their structure and performance are different, so they are applied in different fields. Even in the same field, their grinding and dispersing effects are different. Therefore, only by understanding the respective characteristics of horizontal and vertical grinders, can we better choose the type of grinder.
Generally speaking, the vertical grinding machine can choose the ordinary 0.1-2 mm grinding medium, the ordinary horizontal grinding machine can use 0.3-2 mm grinding medium, the dual-power centrifugal separation can use 0.03-1 mm grinding medium, the selection of suitable grinding beads often has twice the result with half the effort. The specific type of grinding machine matches the recommended grinding beads.


In the actual production process of ceramic grinder, the density, hardness and particle size of the grinding medium used have an important impact on the grinding efficiency.

The main factors affecting grinding efficiency include:

1. Reasonable structure of grinding chamber;

2. Energy density;

3. Linear velocity;

4. Velocity gradient between grinding media in grinding chamber (velocity difference, the greater the velocity difference, the more efficient);

5. The grinding medium is fully circulated in the grinding chamber without dead angle.

6. The size, roundness and specific gravity of grinding medium;

7. Ratio of material size to grinding medium diameter.

The higher the linear speed of the grinder, the greater the kinetic energy transferred to the beads, and the higher the efficiency of the grinder. But is the higher the linear speed of the grinder, the better? Of course not! The disadvantages of the high linear speed of the grinder are as follows:

1. The higher the linear speed is, the greater the heat is, and the faster the machine warms up. Most materials have temperature limitations.

2. The higher the linear velocity is, the greater the impact on the grinding medium of the grinding machine will be, and the grinding medium will probably be broken.

3. The higher the linear speed, the greater the damage to the machine, the worse the wear of the parts, and the higher the material requirements of the manufacturing machine.

The real effective grinding area of laboratory grinder is the narrow area between the grinding disc and the barrel wall, and the other parts are the heating area. Therefore, the highest grinding efficiency can be achieved only when the grinding medium is concentrated in the effective grinding working area with the appropriate linear velocity.

Blade grinder

It can be used for ball milling mixing of raw materials, fining of finished products and mixing of finished products. Some glaze products should be treated by ball mill water milling, such as black and praseodymium yellow products in glaze colors. The quality of water milling treatment is different from that of finer products.

Ball mill mixtures are used to produce zirconium iron red and aluminium iron red in ceramic pigments. Ball mill mixing time of zirconium iron red is between 8 and 12 hours. The proportion of raw material, ball stone and water used in ball mill is also one of the key factors. Reasonable proportion can increase ball milling efficiency and reduce ball milling time.

The grinding machine is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials and a grinding head. The cylinder body is a long cylinder with a grinding body inside. The cylinder body is made of steel plate. The steel lining plate is fixed with the cylinder body. The grinding body is generally a steel ball and is loaded into the cylinder according to different diameters and proportions. The grinding body can also be used in steel sections. Material enters the mill head silo evenly by screw of feed device through feed hollow shaft. There are ladder lining plate or corrugated lining plate in the silo. There are steel balls of different specifications in the silo. The centrifugal force produced by the rotation of the cylinder brings the steel balls to the specified requirements and then falls down, which has a heavy blow and grinding effect on the material. After the material is roughly grinded in the head silo, it enters the next silo through a single-layer partition board. The silo is equipped with a flat lining board and steel balls to further grind the material. The powder is discharged through the discharging grate to complete the grinding operation.

In the process of turning the cylinder of lithium-electric special grinder, the abrasive body also slips. In order to make use of the abrasive effect, the cylinder of lithium-electric special grinder is divided into two sections with partition board when the particle size of the material is bigger than 20 meshes. That is to say, the material is smashed by steel balls when it enters the head silo and the material enters the next silo. The section grinds the material. The qualified material is discharged from the hollow shaft of the discharging end. When the material with small feed particles is grinded, such as sand No. 2 slag, coarse fly ash, the cylinder of the mill can be grinded into a single silo without partition, and the grinding body can also be used as a steel section.

The raw materials of the special silicon-carbon grinding machine are fed into the hollow cylinder through the hollow Journal for grinding. The cylinder is equipped with grinding media of different diameters (steel ball, steel bar or gravel, etc.). When the cylinder rotates around the horizontal axis at a rotating speed, the medium and material in the cylinder will fall or roll off the inner wall of the cylinder when its gravity is greater than the centrifugal force under the action of centrifugal force and friction. The ore will be broken by impact force. At the same time, the sliding motion between grinding media also produces abrasive effect on raw materials in the process of grinding machine rotation. The grinded material is discharged through the hollow journal.


FAQ
Horizontal sander "strike"
To solve this problem, first of all, we need to check whether the power supply of the grinder is working normally, whether the fuse is fused, and whether the tension spring is broken. As long as the "disease" repair work will be very simple, it is nothing more than to switch on the power supply, replace the new fuse, replace the tension spring. If the machine suddenly does not work, then we should...more
