2. Dacheng county "three treasures": Donkey Meat fire, Jinsixiaozao, xuejiawotou. Dacheng donkey meat: Dacheng donkey meat is a local famous specialty, commonly known as "sky dragon meat, underground donkey meat" are delicacies. Dacheng donkey meat originated from Ming Dynasty. It is made by ancestral method, with exquisite ingredients, unique flavor, pleasant fragrance, beautiful but not greasy. It is one of the "three treasures" of Dacheng diet. Li Lianying, the eunuch in charge of the Qing Dynasty (from Dacheng), once offered Dacheng donkey meat to Empress Dowager Cixi, which was known as "treasure on the ground". Since then, Dacheng donkey meat has gained a great reputation and must be bought and tasted by passers-by. Since the reform and opening up, Dacheng donkey meat has been developed and sold nationwide by traditional processing methods, high temperature disinfection and vacuum packaging. It has become a tourist food and table delicacy, and is popular among consumers. It's very good. I'm a stranger who works in the big city. When I first came here, I always ate the fire of the big city,

3. 1、 Material texture selection. The quality of materials is the key to affect the output of crushing proction line in operating quarry, especially the hardness of sand materials directly determines the effect of sand crushing. 2、 It is necessary to have strict specifications for the feeding size, and the feeding requirements must meet the requirements of the supporting equipment of the stone proction line. It should be reminded that the long-term collision of materials in the vibrating screen will cause the deformation of the screen, and it will also lead to large pieces of unqualified materials directly into the crushing equipment cavity, which not only reces the proction of sand proction, but also speeds up the wear of vulnerable parts and equipment. 3、 There should be sufficient material resources to guarantee, such as limestone, river pebbles, cobbles, etc. to be able to timely and effective supply, so as not to affect the proction progress and output. 4、 There should also be an open space favorable to the proction of impact crusher, because no matter what kind of proction process plan, the crushing sand proction line contains a lot of supporting equipment, large and small, and these equipment can achieve the maximum proction effect only when they are installed on a stable and firm foundation and reasonably designed. 5、 There should be a convenient transportation channel, no matter whether the incoming and outgoing materials can be guaranteed to be transported to the designated proction site, and will not delay the high-speed operation of the impact crusher proction.

4. 1. The influence of crushing equipment factors
for the same crushing operation, the proctivity of different types of crushing equipment is different, and the proctivity of the cycle is 2-3 times of that of jaw type with the same size of ore feeding and proct. Among the similar jaw crushers, the proctivity of compound penlum crusher is 20-30% higher than that of simple penlum crusher. For the same type of equipment, the absolute value and relative value of proctivity increase with the increase of size
with the increase of the rotating speed, the proctivity of the crusher increases slightly, but the power consumption also increases. When the rotating speed increases greatly, the power consumption increases sharply, but the proctivity increases little. Too high speed will also lead to proctivity decline and crusher blockage, because discharge also takes a certain time, especially in the medium and fine crushing cone crusher, too high speed will increase the centrifugal force of materials and block the crushing chamber. Therefore, there is usually no need to increase the speed to increase proctivity
the size of the ore outlet actually determines the working quality and load of the crusher. Although the proctivity is high when the outlet is large, the crushing ratio decreases and the crushing effect weakens. When the discharge port is large, most of the materials pass through the crusher almost without crushing, which has little crushing effect. Although the crushing ratio is high, the proctivity is too low. The crusher of a certain type and specification has a suitable crushing ratio range, that is, a certain range of ore discharge adjustment. It should be carefully selected and adjusted according to the working conditions of each crushing section
the bite angle (or bite angle) of jaw crusher (refers to the angle between the movable jaw plate and the fixed jaw plate when the ore is clamped) is too small, it will not play much role in crushing, and when it is too large, it will push the ore out of the crushing chamber, and can not achieve crushing. To achieve crushing, we must first clamp the ore
2. The influence of operation factors
the operation factors of crusher also affect the proctivity of crusher. Continuous and even ore feeding can not only make the proction normal, but also make the proctivity larger. When closed-circuit crushing is adopted, because a large amount of circulating load is added to the ore feed, the particle size of the ore feed becomes relatively fine, and the circulating load can become qualified intermediate proct with a little crushing. Therefore, in closed circuit operation, the crusher can work with full load and high efficiency, and the proction capacity will be increased. Depending on the ores with different hardness, the proction capacity can be increased by about 15-40% in closed circuit operation
3. The influence of ore properties
the harder the ore is, the greater its compressive strength is, the more difficult it is to break, the worse its fragility is, and the lower the proction capacity of the crusher is. On the contrary, it is higher
when there are many large pieces in the feed, the average particle size of the ore is coarse and the crushing workload is large, so the crushing capacity is low; When there are many small pieces in the feed, the proction capacity of crushing is large. The proction capacity of the crusher is higher than that of the ore with loose crushing structure and developed cleavage. When there is a large amount of mud or fine ore in the ore, these fine materials will agglomerate or stick to the coarse ore e to the increase of humidity, thus increasing the viscosity of the ore, recing the discharge speed of the crushing process, blocking the crushing cavity, and even making the crushing process impossible.
