The durability and effectiveness of jaw plates significantly impact the overall performance of the jaw crusher. When materials are fed into the crusher, they are subjected to immense pressure as the movable jaw compresses them against the stationary jaw. The shape, design, and material composition of the jaw plates are critical in determining the crushing efficiency. High-quality jaw plates contribute to the longevity of the crusher, ensuring consistent performance over time.
The most common barbed rope is 14*14 and 12*14 wire diameter barbed rope. The 14*14 wire diameter barbed rope is made of 200mm galvanized wire, and the barbed distance can be directly adjusted from 8-12cm. According to the different needs of each customer processing customized. Similarly, the length of each bundle of barbed rope can be cut from 50-250m as required. The 12*14 standard barbed rope is twisted by two different specifications of galvanized wire for 260mm and 220mm barbed wire. Other parameters are roughly the same except for different wire diameters. The price is slightly expensive because the latter uses more materials.
Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.
The construction of inner wall and outer wall steel wire mesh can effectively solve the wall cracks, falling off, empty drum phenomenon. Hot dip galvanized steel wire mesh material requirements: net surface leveling, width and length to meet the project required standards, welding process, weight, zinc, etc., with more production and operation, detection certificate is complete.
The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
Annealed wire is mainly through low carbon steel heating, hot drawing, constant temperature and other processes made into soft iron wire, because in the use of different, so there are different in the production process, made of a variety of specifications. Annealed wire can be widely used, mainly because annealed wire and other kinds of iron wire, has many advantages.
Large rolls of galvanized silk play a very important role in our life. Made of low carbon steel rod processing, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
Blade rope in the world has been widely used in the military, prison, government agencies, banks; Living community wall, private residence, villa wall, doors and Windows, highway, railway guardrail and border line and other protection security.
Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.

With the rapid development of market economy, all walks of life are improving the production process and quality of products, galvanized iron wire industry is of course no exception. However, because of the different types of galvanized iron wire, its characteristics and production technology are also different. Galvanized wire selection of high quality low carbon steel rod processing, is the selection of high quality low carbon steel.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.
The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
