What are the precautions for purchasing welding positioner?

Welding positioner mainly refers to a type of equipment that can play an auxiliary role during welding. It is mainly used for welding that requires the workpiece to be able to achieve position shifting during welding, so that a relatively ideal welding position and an ideal welding rate can be achieved. Welding positioner can be used with many other types of machines to form an automatic welding type, and can also be used for workpiece position shifting during manual welding. There are many types of positioners on the market, so it is also a problem for consumers when choosing. Here are some precautions for purchasing welding positioners for your reference.

Common types of welding positioners

Welding positioner

1. Double-column single-rotation type: The main feature of this type of welding positioner is that the motor-driven working device at one end of the column runs in one rotation direction, and the other end is driven by the active end. The columns on both sides can be designed as lifting type to meet the welding needs of product structures of different specifications. The disadvantage of this type of welding positioner is that it can only rotate in one circumferential direction. Therefore, when choosing, pay attention to whether the weld form is suitable.

2. Double-seat head-tail double-rotation type: The double-seat head-tail double-rotation type welding positioner is the activity space of the welded structural parts, and adds a rotational freedom on the basis of the double-column single-rotation welding positioner. This type of welding positioner is more advanced, with a large welding space, and can rotate the workpiece to the required position. It has been successfully applied in many engineering machinery manufacturers.

3. L-shaped double-rotation type: The working device of this type of welding positioner is L-shaped, with rotational freedom in two directions, and both directions can rotate ±360° arbitrarily. The advantages of this welding positioner are good openness and easy operation.

4. C-shaped double-rotation type: The C-shaped double-rotation welding positioner is the same as the L-shaped double-rotation welding positioner, but the tooling fixture of the welding positioner is slightly changed according to the shape of the structural parts. This type of welding positioner is suitable for welding structural parts such as buckets of loaders and excavators.

Precautions for purchasing welding positioners

Welding positioner

1. When choosing, you should first look at the function of the machine. Check whether the specified translation or vertical movement is a curve or a straight line.

2. Check whether the movement during rotation is continuous or intermittent. Generally, choose a machine that can perform linear motion and achieve continuous flipping.

How to control the moisture content of briquetting machine materials?

In the field of industrial production, briquetting machine as a kind of equipment to convert powdered materials into pellets, its performance and finished product quality are crucial to the whole production process. The water content of the material is one of the key factors affecting the balling effect, which is directly related to the strength of the pellet, the molding rate and the efficiency of the subsequent processing. In this article, we will discuss how to accurately control the water content of briquetting machine materials to optimize the production process and improve product quality.

Water content of briquetting machine materials

briquetting machine

1. The importance of water content

Water content is crucial to the working effect of briquetting machine. The right amount of water can be used as a lubricant to reduce the friction between materials and improve the molding efficiency. At the same time, moisture also helps to improve the strength and stability of the pellets. However, too much or too little moisture can negatively affect the balling effect. Therefore, accurate control of moisture content is the key to ensure the normal operation of the ball press.

2. The impact of water content on the quality of balling

Too much water: when the water content of the material is too high, the ball will easily become fluffy and weak, with insufficient strength, which is difficult to meet the requirements of industrial applications.

Too little moisture: on the contrary, if the moisture is not enough, the bonding force between the materials will be weakened, resulting in easy crumbling of the pellets, affecting the molding effect.

3. Methods to control the moisture content

Pre-treatment: Before the material enters the ball press, its moisture content can be adjusted by pre-treatment such as drying or wetting.

Mixing control: In the mixing process, accurate control of water addition is a common method to control the water content.

Real-time monitoring: Use the water content monitoring equipment to monitor the water content of the material in real time so as to adjust it in time.

What are the transmission methods of the briquetting machine?

In modern industrial production, briquetting machine play a key role in converting powdered materials into pellets with specific shapes and sizes. This transformation not only improves the transportation and handling efficiency ofthe material, but is also often a pre-step for certain chemical reactions or sintering processes. The performance and efficiency of a briquetting press depends heavily on the design of its drive train. In this article, we will discuss in depth the transmission methods of ball presses, analyze their features, advantages and applicable scenarios, and provide industrial users with important references when selecting and applying ball presses.

Transmission mode of briquetting machine

briquetting machine

1. Motor driven hardened gear reducer

This transmission mode drives the hardened gear reducer through the motor, the low-speed output shaft of the reducer is parallel to the double shaft, through the gear coupling to drive the ball roller relative operation. This type of transmission is suitable for dry powder molding and can provide stable roll rotation and long gear life. Due to its high torque and high line pressure, this type of transmission is very popular in metallurgy, refractory materials and other industries. The ball roller of this transmission mode has stable rotation, long gear life, high transmission torque, and the line pressure of roller surface is up to more than 100KN.

2. Single shaft reducer transmission

This is a common drive mode of briquetting machine in the current market. The motor through the reducer will transfer the power to the single shaft, and then through the coupling to drive a pair of large gears on the ball roller shaft relative movement. This form of suspended gear is widely used because of its simple structure and lower cost. Because of its simple structure and low price, it is widely used in China.

What are the factors that affect the particle size of the high pressure roller mill?

High-pressure roller mills are widely used in major mines and related material crushing industries. They have the characteristics of large production capacity, fine particle size, low unit crushing energy consumption and steel consumption. After years of research, it has been found that the particle size of the high-pressure roller mill is not only related to the properties of the original ore, but also to factors such as operation.

Factors affecting the particle size of the high-pressure roller mill

High-pressure roller mills

1. Roller surface pressure

Through experiments, it was found that increasing the roller surface pressure of the high-pressure roller mill will make the particle size of the middle and side materials finer, the particle size distribution of the middle material more concentrated, and the particle size distribution of the side materials more uniform. The crushing effect of the high-pressure roller mill on the material mainly depends on the pressure on the material near the small gap between the two rollers. The specific pressure (the ratio of the total pressure provided by the hydraulic system to the diameter and width of the roller) is usually used as an operating parameter to measure the working pressure.

As the roller surface pressure increases, the uniformity coefficient of the intermediate material increases, the particle size distribution becomes more concentrated, the crushing ratio increases, the discharge particle size becomes finer, and the fine-grained part of the intermediate material after crushing accounts for the majority; as the roller surface pressure increases, the uniformity coefficient of the side material decreases, the particle size distribution becomes wider, the crushing ratio increases, the discharge particle size becomes finer, and the high-pressure roller mill side material is closer to the conventional crushing product.

The fine-grained part of the intermediate material after crushing accounts for the majority, because in the crushing process, the “size effect” of mineral particles (the mechanical strength of ore particles increases significantly with the decrease of ore size) makes fine-grained materials more difficult to crush or no longer crushed than coarse-grained materials under a certain roller surface pressure, so that the fine-grained part of the product accounts for the majority.

The side material of the high-pressure roller mill is closer to the conventional crushing product, which is caused by the “edge effect” of the roller during the crushing process. The lower roller surface pressure of the baffles at both ends of the roller and the edge of the roller makes it easy for the material to slide relative to the edge of the roller, weakening the crushing effect of the material layer, so that the crushing method of the roller edge on the material is closer to the conventional crushing method.

2. Roller surface speed

High-pressure roller mills

Under the same roller surface pressure, when the roller surface speed increases to a certain amount, the uniformity coefficient of the intermediate material increases, the particle size distribution is more concentrated, the crushing ratio increases, and the product particle size becomes finer, but the influence on the uniformity coefficient of the side material and the change in the crushing ratio are not obvious; but when the roller surface speed continues to increase, the change in the crushing ratio of the intermediate material is no longer obvious.
