After roller shell off the machine, grinding is usually performed after 24 hours to prevent cracking and dimensional deviation. During the roller shell and grinding process, the material, hardness, bonding agent, particle size and coolant of the grinding wheel should be reasonably selected. During the grinding process, the grinding burn of the roller is strictly prevented. The grinding burn is classified according to the severity as follows: the burn is not visible to the naked eye → the surface color changes → flaw detection Visible cracks → visible cracks → mesh turtle cracks skin → peeling. In the work roll grinding, each time the minimum amount of grinding should ensure that the fatigue layer is removed, the depth of this layer is generally 0.15-0.30mm. In roll grinding, it should be noted that the diameter difference of the mating roller shell must meet the design requirements.

Roller shell includes  Stainless Steel Roller Shell  and Casting Steel Roller Shell. Before use, grease, dust, and rust should be removed from the surface before routine testing. In particular, the surface of the roll body and roll neck should be carefully inspected for defects such as scratches, indentations, rust spots, and cracks. No roll with surface defects should be used on the machine. Before rolling, the surface quality, sheet composition, and hardness of the rolled billet should be carefully inspected. When the belt is to be connected, the interface must be smooth and free of projection. Roller cooling liquid should ensure uniform and sufficient cooling and lubrication of the roll during rolling, and prevent the hardness from falling or even cracking due to the high working temperature of the roll or local overheating. Roller diameter should be well lubricated and cooled to prevent overheat damage to the surface. The bearing system is to be lubricated and coo...

We can finish our work well once have a good management system. Today we will share the roller shell management. Before use, a roller shell use card shall be established to record the roll number, size, and roll. After the end of roll life, the roll will be used as the original record. The upper and lower rollers of the roller shell shall record the time of up and down the machine, the number of steel rolled, the specifications, the amount of rolling, and the reason of grinding (such as normal roll change, variable specification roll change, scratch, peeling, sticking steel, crack Wait. After every grinding of the roller shell, the starting time of grinding, the diameter before and after grinding, the amount of regrind and the reason of dressing should be recorded. According to the rolling material, a reasonable rolling process (rolling passes, single-pass reduction and rolling speed, etc.) is established, and a corresponding roll change system is established for different r...

Roller shell  is often used in pellet mill. Do you know how its handling and storage? The roller shell must be loaded and unloaded with lifting straps during handling to prevent dents. Rolls should be stored in a dry and ventilated room to prevent moisture, and do not store in acid, alkali and other chemical corrosive environments. The roller shell surface should be coated with anti-rust oil before storage. The installation and disassembly of the roller shell should be very careful to prevent scratches or scratches on the roller surface. The hot roller shell should not be stacked on wet and cold floors and should avoid collisions between the rollers. After grinding, the roll on the machine should pay attention to rust prevention.

We will continue to talk about the advantages of granulator/ pellet mill machine  in this news. 1. Good liquidity and easy management. Due to the good fluidity of the pelleted feeds, there is very little stickiness, and pelletized feeds are the most popular for farms that use automatic feeders to scale up dairy cows or poultry. 2. Avoid automatic classification of feed ingredients and reduce environmental pollution. After the granules are made, there is no grading of the feed ingredients, and the granules are not easy to dust. In the feeding process, the granules have less air and water pollution than the powder. The 3. Kill Salmonella in animal feed. Salmonella is preserved in animal tissues when ingested by animals. People who eat this bacteria will get salmonella stomach disease. The method of re-granulation by steam high temperature quenching can kill Salmonella in animal feed. In the aspect of chemicals, powders used as wet blends are ground into granules, dried to comp...

In this article, we will talk about the advantages of granulator/pellet mill machine. 1. Pellet mill machine, such as  wooden pellet machine , can avoid animals picky eaters. Formulated feed has a variety of raw materials, nutrition, comprehensive, can prevent animals from the powder to choose their favorite, refused to intake of other ingredients phenomenon. Due to the uniformity of pellet feed during storage and feeding, feed loss can be reduced by 8% to 10%. The 2. Pellet mill machine has high feed returns. During the granulation process, due to the combined effects of moisture, temperature and pressure, some physical and chemical reactions occur in the feed to gelatinize the starch and enhance the activity of the enzyme, which enables the fed animal to digest the feed more efficiently and convert it into an increase in body weight. . Feeding poultry and pigs with pelleted feed can improve the feed conversion ratio (ie, return rate) by 10% to 12% compared to powdered feed. ...

We know that pellet mill machine/granulators include  flat die pellet mill machine  and  ring die pellet mill machine . Today we will introduce the general work of pellet mill machine. Pellet mill machine/granulators mainly consist of feeding, stirring, granulating, transmission and lubrication systems. The working process is to require the powder with a content of no more than 15%, from the hopper to the feeding auger, by adjusting the speed of the stepless speed regulation motor, to obtain the appropriate material flow, and then enter the stirrer, stirring and steam through the stirring rod. Mixing and tempering, if you need to add molasses or grease, but also from the mixing tube and steam with the quenching and tempering, the amount of grease is generally not more than 3%, otherwise it is difficult to form, after conditioning with powder temperature up to 64 ~ 85 °C the humidity reaches 14 to 16%. Then, iron impurities mixed in the powder are removed through a chut...

Granulators are now not only limited to use in feed mills, but many large farms are also introducing this granulation equipment for low-temperature granulation of organic fertilizers. High efficiency wooden pellet machine and pellet mill spare parts can make our work smoothly. 1, Workers wear tight overalls, cuffs do not open, do not wear gloves, wearing protective caps and dust masks, the operation must focus on energy. 2, Check the reducer oil level, particle machine spindle bearings and roller bearing oil level. 3, Familiar with the working principle of the machine and the structure and function of each part. 4.

Pellet machine ring die  is an important part. Do you know how to install it to keep  long life ring die ? The misalignment of the position of the ring die can cause uneven wear and uneven granulation, and even ring motion, reducing the particle yield and quality. When installing the ring mold, be sure to install it correctly and do not tilt it. If the ring mold is tilted, it will affect the smoothness of the operation of the pelletizer, resulting in unbalanced stress on some parts and components, such as spindle bearings. At the same time, it will also cause uneven wear of the ring mold and the pressure roller. When assembling the ring die, the amount of run-out of the end face of the ring mold should be controlled and should be controlled within 0.2 mm. This can be controlled by a dial indicator. Experienced operators can use fine wire placed on the end face of the ring die and then the ring die can be controlled visually. Other questions about pellet machine ring die...

The reason why  wooden pellet mill  can not be formed can be seen from two aspects: one is raw material, and the other is wooden pellet mill pressing equipment. 1. Raw materials. First, the moisture content of raw materials. To make pellets of wood pellets, the moisture content of raw materials is an extremely important indicator. Different raw material requirements are different. On the other hand, the raw materials themselves, wood chips, straws, paper scraps and other raw materials have different properties. The fiber structure is different, and the degree of difficulty in molding is different. 2.  Wooden pellet mill machine . The larger the compression ratio, the thicker the template, the longer the material compression time, and the higher the molding rate of the particles. If the mold thickness does not reach a certain standard, the wood chips are more difficult to form, certainly not limited to sawdust. Another machine The factor is the clearance between the...
