A new generation of high-speed rotary shear superfine grinding equipment with high performance and wide adaptability - QFJ fiber ultrafine grinding mill (also known as CXJ microfiber mill) was successfully developed by Zhejiang Fengli Crushing Equipment Co., Ltd. , And recently passed the new product technology appraisal in Zhejiang Province. Experts believe that the new product has the characteristics of ultra-fine crushing effect, low energy consumption, low material temperature rise in the crushing process, smooth discharge, convenient maintenance and other characteristics, and its technology is at the leading domestic level and reaches the level of similar international products.
It is reported that ultra-fine shear grinding is one of the most important deep-processing technologies for cellulose derivatives, such as papermaking pulp, refined cotton, CMC (carboxymethyl cellulose), military and civilian nitrocellulose, plant stalks, and Chinese herbal medicines. Need to finely crush. However, at present, the production of fiber ultrafine shear grinding mills in China is still in its infancy, and so far it is still using ordinary crushers. Its disadvantage is that the materials are gradually crushed only by the impact rubbing, and the temperature rise during the production process is high and the energy consumption is high. The output is low, and the particle size after comminution of materials is generally not more than 50 mesh, which is far from adapting to the requirements of the present cellulose derivatives for the particle size of the fine powder. Although foreign models have many models with good structure and performance, they are expensive.
In response to this situation, Zhejiang Fengli Company, which enjoys the reputation of “China Crusher Expertâ€, adopts the advanced technology of German HOBER ultrafine powder and adopts the principle of single-angle shearing in turn to finally solve the bulk of fiber materials effectively. The problem of ultra-fine grinding, in which the fineness of refined cotton can reach more than 80 mesh (97% pass rate), the unit energy consumption is only about 70% of other domestic models.
The structure of this machine is novel. There are several movable knives distributed on the rotor. There are several fixed knives on the static knives, and the shear knives are used to set the movable knives and fixed knives. The gap is adjustable as required, the minimum is adjustable to 0.5mm; Design, theoretical crushing capacity up to 100,000 knives/point or more; moving and fixed knives made of high-strength, impact-resistant special alloy wear-resistant materials, long tool life and can be repeatedly grinding; using computer-aided design of the box The body has features such as smooth air flow in the chamber, smooth material discharge, and low noise, which greatly reduces the sticky wall phenomenon of the fine powder materials; the material pulverization is performed at room temperature, and the powerful airflow generated by the high-speed rotation can timely take away the pulverized material. The heat generated at the time ensures a low temperature rise in the crushing process; the operating procedures are safe and reliable, and the maintenance and material cleaning are simple, quick and convenient.
The fiber ultrafine pulverizing equipment consisting of QFJ fiber ultrafine shear grinding mill and other supporting machines is a full set of process equipment for crushing and producing ultra-fine fiber materials at room temperature, which can be widely used in chemical, plastic, Rubber, papermaking and other industries; dry ultra-fine comminuted velvet, cotton fibers, cellulose ether products and film products (such as: refined cotton, cotton and linen; optical fiber, foam; rubber, plastic film, film, etc.) materials. Single machine output can reach more than 500Kg/h, fineness is 20-325 mesh (adjust the crushing gap to adjust fineness).
Tested by Zhejiang Fangyuan Testing Co., Ltd., the performance indicators meet the Q/ZFL 014-2003 product standard requirements. It has successfully replaced imported equipment for several domestic refined cotton manufacturers, the price is only 1/3-1/5 of the imported equipment; confirmed by the actual use of the user, the equipment is ideal for deep processing of the ultra-fine powder industry equipment.
