How to choose the hammer and screen of the grain corn maize grinding hammer mill?

The hammer and the screen are both important parts of the grain corn maize grinder machine, and they are also the most easily worn parts. Choosing suitable hammers and screens has a lot of benefits. RICHI will analyze for everyone from the following aspects:

The choice of feed mill hammers

The hammer is the most important part of the grain maize corn mill grinder, and it is also the most easily worn part. The crushing effect of a grain corn crusher grinder depends largely on the quality and type of the hammer and the installation of the hammer. The following is a brief description of how to choose a hammer from the types of hammers, the quality of the hammers and the installation of the hammers.

1. Types of hammers of grain hammer mill grinder

   At present, there are many types of hammers, with different shapes, but the most commonly used in the grain corn sorghum hammer mill crushing machine is the plate-shaped rectangular hammer.

   Because this hammer is not only simple in structure and easy to manufacture, but also has good versatility and strong wear resistance.

   Nowadays, the hammers used in grain corn grinder machines have been standardized, divided into three types of standard hammers, type 1, type 2, and type 3, and these three standard hammers are all rectangular double-hole hammers.
   

2. The quality of the grain corn mill grinder hammer

   The quality of the grain corn mill grinder hammer mainly depends on its material, heat treatment and machining accuracy. At present, the main manufacturing materials of hammers for grain corn mill grinder crushers are low-carbon steel, medium-carbon steel and special cast iron.

   No matter what material is used, the material composition and production process of the hammer must be strictly controlled to ensure quality and prevent fracture accidents during use.
   

3. Installation of the electric corn grinder hammer

   Pay special attention to the gap between the hammers and the number of hammers when installing the hammers. The number and arrangement of the hammers in the crusher will affect the balance of the rotor, the uniformity of hammer wear, the distribution of materials in the crushing chamber, and the working efficiency of the crusher. As for the gap of the electric corn grinder hammer, it is determined according to the characteristics of the crushed material.

How to determine the appropriate mesh number of screens

The number of meshes is the number of holes, which is the number of holes per square inch. The larger the mesh, the smaller the aperture. Generally speaking, the number of meshes × aperture (number of microns) = 15000. For example, the aperture of a 400 mesh screen is about 38 microns; the aperture of a 500 mesh screen is about 30 microns.

It is also used to indicate the particle size of particles that can pass through the grain corn maize grinding hammer mill sieve. The higher the mesh, the smaller the particle size. Because of the problem of open porosity, that is, because of the difference in the thickness of the wire used when weaving the net.

Different countries have different standards. There are currently three standards: the United States, the United Kingdom and Japan. Among them, the United Kingdom and the United States are similar, while the Japanese standards are quite different. China uses the American standard, which means it can be calculated using the formula given above.

The particle size of the powder is called the particle size. Due to the different product specifications of pellet feed processing equipment, the shape of the produced pellets is complex, and there are usually several expression methods such as sieving particle size, sedimentation particle size, equivalent volume particle size, and equivalent surface area particle size.

The sieving particle size is the size of the sieve holes through which the particles can pass through the sieve, expressed as the number of grain corn grinder machine sieve holes in a 1 inch (25.4mm) wide sieve, so it is called the "mesh number".

Remarks: 1 um = 1 micrometres (micrometer) = 0.001 millimetre (mm)

Factors affecting the crushing effect of hammer mills

1. The diameter of the mesh.

   The finer the grain hammer mill crusher, the more energy it consumes. Enlarging the mesh size can not only save energy, but also increase output and productivity. According to Chinese standards, the sieve hole diameter is divided into four grades, small holes 1-2mm, medium holes 3-4mm, coarse holes 5-6mm, and large holes 8mm.　
   

2. Screen surface area.

   The opening rate increases with the increase of the grain corn hammer mill screen hole diameter, and decreases with the increase of the screen hole distance. The larger the opening rate, the larger the crushing efficiency and productivity.

   Therefore, when selecting corn hammer mill sieves, sieves with larger holes and smaller pitches should be selected on the premise of meeting the feed particle size standards required for feeding.

   But it should be noted that if the hole distance is too small, the strength and rigidity of the screen will be insufficient, and the grain corn grinder machine screen will be easily damaged. Large holes have occurred. In many countries, the opening rate of the corn grinder machine shredder screen has reached 45% or more, and it is generally about 30% in China.
   

3. Humidity.

   The crushing efficiency of the grain maize corn grinder machine is inversely proportional to the humidity of the material. When the humidity is higher than 12-14%, the energy required for crushing increases.　

4. The linear velocity of the end of the hammer of the corn grinder machine crusher.

   For different materials, the best linear velocity is different. The linear velocity of the hammer blade end is proportional to the pulverization fineness.

5. The thickness of the hammer of the grain hammer mill crusher.

   The grain corn mill grinder hammer is too thick and the crushing efficiency is not high. However, due to the large size of the hammer, the large-scale crusher still uses a thicker hammer of 5mm.　
   

6. The number and arrangement of the hammers of the corn mill grinder crusher.

   When the number of hammers increases, the no-load energy consumption increases. When other conditions are the same, the crushing particle size becomes finer and the output decreases.　　

7. The gap between the hammer and the screen of the grain maize grinder machine crusher.

   The gap between the hammer and screen directly determines the thickness of the material in the crushing chamber. The material layer is too thick.

   The friction and crushing effect is weakened, and the powder may block the sieve holes and it is difficult to pass through the sieve holes. The material layer is too thin and the material is too easy to perforate, which will affect the crushing particle size.
   

8. Types of grains
9. The position of the feed inlet.

   There are two types of central feeding and tangential feeding. The central feeding reduces the grain hammer mill productivity by 20%. When the tangential feeding, the material will directly fall into the maximum of the hammer with the airflow. speed ​​zone.　

10. Feeding speed.

    Small load, low output, high energy consumption, excessive load, high output, but the life of the grain hammer mill crusher will be shortened.　

11. The air flow rate in the crusher.

    For long-term continuous operation of the crusher, air should be sucked to avoid clogging the grain hammer mill screen holes.
