(1) Air strike spinner fine crusher. The air strike rotary crusher produced by Xuzhou Wanhe Machinery Manufacturing Co., Ltd. (hereinafter referred to as Wanhe Machinery) can replace the traditional medium and fine crusher cone crusher or hammer type and impact crusher, which has simple process, low investment and low operating cost. High-efficiency crushing production process. It can greatly increase the mill output (30%~50%), reduce the running production cost, and achieve efficient and low-cost operation.
The machine consists of two transmission systems, two rotating bodies are concentrically combined, the inner rotor is a high-speed rotating hammer head, and the outer rotor is a low-speed rotating cylinder. The block is impacted mainly by means of a high-speed rotary hammer to selectively break along the weak portion. The material after the impact obtains huge kinetic energy and is further broken by the impact of the counterattack plate and the material. The material is spirally moved under the action of the rotary cylinder, and is repeatedly crushed in the hammering area, and a large amount of fine powder is generated, which is discharged from the discharge opening. It can be widely used in mineral processing, building materials, sand, electric power, metallurgy, chemical industry, road construction, ceramics and other industries metal (non-metallic) minerals, artificial sand, cement clinker, limestone and coal research stone brittle, hard materials Finely broken. It has been applied in Jiangsu, Anhui, Henan, Shanxi, Shaanxi, Gansu, Hebei, Xinjiang, Yunnan, Zhejiang and other places, and has achieved good economic benefits.
The characteristics of the fine crusher are: 1 The amount of fine powder is large: the material is repeatedly lifted and thrown in the machine, and is continuously crushed and broken. The proportion of fine and powdery materials is as high as 50~80%; 2The power consumption is low: hammerhead The distance between the counterattack plate and the counterattack plate is greater than 300mm, no hard mechanical resistance, uniform load of equipment, power consumption is only 1/3-1/2 of the traditional crusher at the same output; 3 long life of the consumable parts: the thrown material is in suspension Under the implementation of air strike crushing, completely abandon the traditional milling friction smash, the wear is small. The hammer head design gives a working wear of 80~100mm, the service life of the same material is 5~10 times that of the traditional crusher; 4The adaptability is strong: Due to the unique structural design of the machine, the crushing space is large and the application range is broadened. The technical parameters are listed in Table 1.
(2) Air strike screening crusher. The crusher produced by Xuzhou Wanhe Machinery Manufacturing Co., Ltd. consists of two transmission systems. The two rotary bodies are concentrically combined. The inner rotor is a high-speed rotary hammerhead, and the outer rotor is a low-speed rotary cylinder composed of sieve plates. The material enters the crusher cavity from the end face, and the fine particle material is first sieved out under the action of the low-speed rotary sieve plate, and then the large particle material is lifted to a certain height under the action of the large wave rotary sieve plate, and the high-speed rotation is entered. In the hammering zone, the material is subjected to continuous high-speed impact pulverization until it reaches the acceptable particle size and is discharged through the sieve quilting. The crushing process is shown in the figure, and the technical parameters are listed in Table 2.
The characteristics of the air strike crusher are: 1 simplifying the process and saving investment: the machine integrates crushing, screening and lifting functions with a new concept, which greatly simplifies the process flow, saves investment, reduces land occupation, and has simple and reasonable structural design. , easy to maintain and repair; 2 stable particle size, improve production quality: first sieve after breaking, broken with sieve, to achieve dynamic continuous screening in the whole process, qualified materials are discharged in time, no over-grinding phenomenon, the discharge particle size is stable and stable; 3 stable operation, saving power consumption: the distance between the hammer head and the counter-screening plate is greater than 350mm, without forced milling, friction and crushing. The equipment load is uniform and the operation is stable and reliable. The total installed capacity is small, and the power consumption is low; 4The material consumption is small, and the operation cycle is long: the impact is mainly caused by the impact of small abrasion (air strike), so the plate hammer and the counter-screening plate are worn little, and the design is given a hammer 80~ 100mm wear margin, long life of consumables.
