For those engaged in the crushing of waste tires, they all know that there are three major technical difficulties in the crushing of waste tires, namely:
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 123] \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 2, the steel stripping technology in the meridian tire
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 3 o’clock above, two points have been detailed in related articles. This article only introduces fine glue powder crushing technology.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; according to the size of the domestic glue powder particle size, the fine glue powder is set to 60-80 mesh. In order to obtain fine glue powder between 60-80, not only China, but countries around the world are also trying to break through this technical difficulty. To this day, my country ’s technology in the field of fine glue powder is ahead of international level.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; The production and application of waste tire gum powder in our country was approved by the national approval in 1984, and the introduction of multi -sets of lunch glue powder production lines. Although these introduced production lines have failed, the development of domestic fields has plays a role in motivating and promoting the development of this field. By 1996, a fine glue powder technology seminar was held in China. Experts summarized the experience and lessons of failure, and shouted loudly: To be based on domestic! Promote domestic fine rubber powder production technology to start research and development across the country.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; remember the past, domestic fine glue technology first started with fine glue powder in the freezing method system. Its working principle is to pre -cold the coarse glue powder first. In addition, the compressed air expands the gas after cooling, filtering, and drying. The pieces are composed of 40 octagonal hammer head, with a high-speed rotating hammer head to beat the coarse gum. The rough glue powder at -135 degrees has been glassy, \u200b\u200bthat is, the nature becomes the hard and crispy of the glass, and the hammer of the hammer head will quickly become subdivided. When you come out, get fine glue powder. The crushing principle is well understood. Through practice, it is found that the fine rubber powder is taken with the frozen method. ; \u0026 nbsp; 1 \u0026 nbsp; \u0026 nbsp; 40 swing hammer heads at a deep temperature and high -speed operation of hammer, coarse glue powder is convenient to become fine gum powder powderHowever, the glass -mounted coarse glue powder is very hard, so the hard hit, the hammer head has a large wear, so the expensive hammer head life is not long.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 2 \u0026 nbsp; \u0026 nbsp; When replacing the new hammer head replaced the hammer head, the new and old hammer head is due to the difference in weight. Adjust.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; the above two reasons, the maintenance time is extended, the machine efficiency is reduced, and the cost of cold technology has Unable to sell and was quickly eliminated by the market.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; while carrying out the frozen method to obtain fine glue powder, many domestic private enterprise technicians have carried out research and production of fine glue production equipment at room temperature. \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; to achieve fine rubber powder at the normal temperature, the technical difficulty is quite difficult. An undeniable fact: The glue powder has high elasticity at room temperature, and the temperature must produce coking at about 140 degrees, phenomenon, the coking surface carbonization after coking. Lost the good nature of elasticity and become a waste. \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; When the grinding head is grinded, it is inevitable to produce \”temperature rise\”. So how to design the head. Make him during grinding. That is to grind the coarse powder without coking?
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; fine glue powder crusher
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; ; \u0026 nbsp; \u0026 nbsp; According to relevant information, the mechanical fine rubber powder crusher at the earlier temperature of the country is a horizontal motion controller. It is said that this grinding head design is inspired by the principles of stone crusher for corn machines in the countryside and improved design. It becomes adapted to rubber powder, and the tapered head is the same as cooling water. It takes most of the heat during grinding and cutting glue powder to ensure that long -term work is warm, but it does not scorch the rubber powder.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; , Perform glue powder. Fine glue powder quickly leaves the grinding head through the effect of centrifugal force, and it must be finely glue.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; some factories designed the cone -shaped grinding head into a combination of tapered grinding in the form of a pagoda.Hundreds of heads and tools, so that they are convenient for maintenance and increased output.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; know through practice that the cone -shaped grinding head has the effect of \”self -repair\” and has a longer lifetime life.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; this type of crusher, many domestic production manufacturers.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 2 horizontal motion -controlled plane grinding crusher
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; The personnel designed the \”horizontal motion -controlled plane grinding crusher\”.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; The working principle of the crusher is a pair of fixed/dynamic flat surface grinding heads. The coarse glue powder is made from the fixed grinding head, rotates at a high speed of the moving head, and the coarse glue powder is squeezed and cut between the head. Ding/dynamic grinding heads are cooling water and heat dissipation. Cooling water takes away most of the heat. In order to quickly leave the grinding glue powder to quickly leave the grinding head, and then the grinding head plane processing the spiral -shaped expansion line out of the rails to make the fine glue powder make the fine rubber powder. Smooth was thrown out of the grinding head.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; Because the line speed of the head of the head is low, the grandson is less; The plane of the fixed/dynamic grinding head is uneven and must be reset.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 3 horizontal mobilization crusher conventional waste tire crushing is followed by the following procedures:
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; abandoned bulls. -Nrafting machine-fine crusher-sperm fragmentation. However, it can directly process the waste tires into fine glue powder at one time. Its basic working principle is: first fix the waste tires quickly on the feed rack, and the feed rack is controlled horizontally. The fine powder grinded from the cold wind was sent from the cold wind to the warehouse.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; Obviously, this crusher has the characteristics of low processing costs. Unfortunately, this kind of pieces are only suitable for crushing of diagonal tires.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 4 vertical motion controlling crusher
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; The composition of the grinding head, but its grinding head is verticalSports. The material enters the crushing room from the material warehouse located in the upper part of the machine. Using a high -speed rotating moving head knife and a fixed grinding header at the same time squeeze and cut it to crush. Send it. Determine, the moving head is cooling through the water.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 5 airflow mill ultra -fine glue crusher
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; Powder can be screened out of 60-120 mesh, more than 120 meters of ultra-fine glue powder, but after analysis, the content of \”glue powder\” is greatly reduced, while \”carbon black\” occupies a considerable part of the large part Therefore, the quality of glue powder has been greatly reduced.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; To obtain ultra -fine glue powder with more than 200 mesh, you must use airflow grinding pieces.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; the basic working principle of the machine is to compress the air, cool down, filter, and dry through multiple nozzles after drying. Pre -cold \”rubber mix, converge at the junction point of the crushing room, produce a severe collision, self -grinding, forming ultra -fine glue powder. Get ultra -fine rubber powder with more than 200 meters after air -conditioning.
\u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; Of course, the way to obtain fine glue powder is not just the above, such as chemical auxiliary fine glue mask.
