1. There is a big difference between the feeder and the ore drawing machine. The feeder only has the function of transferring materials. Different equipment models are selected according to the size of materials; Generally, the ore drawing machine is equipped with bars in the front of the equipment. Generally, it is used to feed large pieces of materials. Because of the bar bar effect, it vibrates back and forth, and is not easy to block, and it can also play the role of slight crushing and screening
the volume of the feeder is from small to large, and the smallest model of the ore drawing machine is relatively large. If you want to know more about it, please come to Landa general

2. The generator bar is the stator coil. Because it is thick, it can't be wound like the general coil, so it is made into a bar form, which is embedded in the stator core slot ring field installation, and then welded.
3. The working principle of bar feeder is as follows: a pair of vibrating motors with identical performance parameters are used as the excitation source. When two vibrating motors operate in the opposite direction at the same angular speed, the inertial force generated by the eccentric block is repeatedly superimposed or cancelled in a specific phase. Thus, a huge synthetic exciting force is generated, which makes the body vibrate on the supporting spring. With this vibration as the driving force, the animal material slides and casts on the chute, so that the material moves forward continuously to achieve the purpose of feeding. When the material passes through the screen bar on the tank, the smaller material can fall through the screen bar gap without going through the next crushing process, which has the effect of screening.

5. It's about helping children build self-confidence and behavior patterns. What is reflected from the problem that children are "unwilling to solve problems by themselves" is how our parents once treated their children's attitude and way of dealing with difficulties. There are several reasons for children's "always asking others for help"
1. It is related to parents' underestimation of children's ability
for example, the average level of a child is that he will "welcome" and "goodbye" at nine months old, cover himself at one year old, take off his socks at three months old, and so on. When the child is two years old, he will begin to like to take shoes, table and broom for his parents. When the child takes doing housework as a very happy thing, our parents think that he is making trouble, not giving support and guidance, but drinking and scolding or putting things away. Let children feel that their ability is too weak, their ability can not be recognized by alts.
2. It is related to the children's way of doing things from childhood
for example, when a child wrestles, our parents usually don't help him summarize and recognize the reasons for wrestling, encourage and support him to try again, but often remind him loudly: & quot; Did you forget that you fell there& quot; The implication is that you dare to go even if you have fallen there. I don't know how to be afraid! And such a kind of reminder forms that children don't know how to face the behavior pattern when they encounter difficulties, and that children focus all their attention on "difficulties" when they encounter difficulties, rather than thinking about how to solve them
3. It is related to parents' failure to help their children accumulate experience in facing difficulties
any behavior pattern and ability of a child needs our parents to accumulate relevant experience for him. Based on the above two reasons, our parents help their children to accumulate the experience of giving up when they encounter difficulties, instead of helping them to accumulate the experience of meeting difficulties, facing difficulties and solving difficulties, so they "always ask others to help."
after understanding the reasons behind children's behavior, please pay attention to the following points in your daily life:
1. Be an encourager and supporter of children
when your child asks you to solve the problem, you will study and analyze the problem with him, then work with him to solve the problem, and tell the child afterwards what you have done well in what you have just done, and encourage and praise him. And tell him: & quot; You believe he will do better and better next time& quot;<
2. Be a cheerleading team to help children build self-confidence.
give children more opportunities to do things for us. And in the side for his encouragement, refueling, and timely guidance, so that he can successfully complete, so as to enhance his self-confidence

we will not be the "magnifier" and "intimidator" of children's difficulties. We need to be difficult "analysts" and "focus shifters"! In other words, when children encounter difficulties, what we should do is: let children focus on how to solve the problems, that is, what methods can solve the problems, not the difficulties themselves. For example: climbing up and falling down, go with him to see why I fell down just now? Is it hand or foot?... After finding out the reason, encourage him to try again and tell him that you will support and protect him. Come on
in this way, we help children establish an achievement mechanism that they are willing to face when they encounter difficulties - I can! I'm great! I will do! In this way, our children will have this kind of thinking mode to think and seek solutions when they encounter difficulties, and become a confident and brave child!

6. Performance characteristics of rod mill:
the particle size characteristics of rod mill procts are related to the situation of rod grinding ore. When the bar strikes the ore, it first strikes the coarse particles, and then grinds the smaller particles, thus recing the risk of over crushing. When the bar rotates and rises along the liner plate, coarse particles are sandwiched between them, like bar screen, which allows fine particles to pass through the cracks of the bar. This is also concive to crushing coarse particles and concentrating coarse particles in the place where the grinding medium strikes. Therefore, the proct of rod mill is more uniform and the over grinding is lighter
difference:
1. Grinding medium
(1) ball mill: the grinding medium in the mill is mainly steel ball or steel section. This kind of mill is most commonly used
(2) rod mill: steel rods with a diameter of 50-100 mm are installed in the mill as grinding medium. The ratio of length to diameter of rod mill is generally 1.5-2
(3) baseball mill: this kind of mill usually has 2-4 bins, in the first bin, cylindrical steel bars are loaded as grinding medium, and then each bin is loaded with steel balls or steel sections
the ratio of length to diameter of the ball mill should be about 5, the ratio of the length of the bar bin to the effective diameter of the mill should be between 1.2 and 1.5, and the length of the bar should be about 100 mm shorter than that of the bar bin, so as to facilitate the parallel arrangement of steel bars and prevent cross and disorder of bars
(4) gravel ball mill: the grinding media in the mill are gravel, pebble, ceramic ball, etc. Granite and porcelain are used as lining plates. Used in white or color cement and ceramic proction< (1) steel rods with diameter of 50-100 mm are commonly used as grinding medium in rod mills, while steel balls are used as grinding medium in ball mills. The length of steel rods is 25-50 mm shorter than the cylinder, and high carbon steel with carbon content of 0.8% - 1% is often used; The loading capacity of the rod is about 35% - 45% of the effective volume of the rod mill. When observed with naked eyes, the horizontal plane of the rod is about 100-200 mm below the cylinder centerline
(2) the ratio of length to diameter of rod mill cylinder is generally 1.5-2.0, and the inner surface of lining plate on end cover should be vertical plane. The purpose is to prevent and rece chaotic movement, bending and breaking of steel rod in cylinder, and ensure regular movement of steel rod. The ratio of cylinder length to diameter of ball mill is small, and in most cases, the ratio is only slightly greater than 1
(3) rod mill adopts overflow and open discharge instead of grid plate discharge; The diameter of the hollow journal at the discharge end is generally larger than that of the ball mill of the same specification. The rotational speed of the cylinder of the rod mill should be lower than that of the ball mill of the same specification, so that the medium in the cylinder can work in the state of dropping down
3. Proction capacity
both ball mill and rod mill are important mine mills. Their proction capacity is related to the following factors: grindability of ore, particle size of feed and final proct, type and size of mill, shape of liner, shape, size, proportion, hardness and density of grinding medium, working speed of mill, filling rate of grinding medium, grinding concentration, The amount of return sand and the working efficiency of classification equipment. Because there are many factors that affect the proction capacity of the grinding machine, and the factors vary greatly, there is no theoretical formula to accurately calculate the proction capacity of the grinding machine. Therefore, the proction capacity of grinding machine is generally calculated by approximate method according to empirical formula. There are two commonly used calculation methods: grinding machine according to the unit proction capacity of ore meter calculation method (also known as volumetric meter algorithm) and grinding power calculation method. The volume calculation method is commonly used in China, which is more convenient< (1) rod mill is often used in gravity separation or magnetic separation plant of tungsten tin ore and other rare metal ore in order to prevent the harm caused by over crushing
(2) in some cases, it can replace short head cone crusher for fine crushing. When dealing with softer or less hard ores (especially those with high viscosity) and grinding 19-25 mm (or even 32 mm) ores to 6-10 mesh with rod mill, the configuration is simpler and the cost is lower than that with short head cone crusher and screen closed circuit, and the st removal of crushing workshop can be simplified. For hard ores, it may be more economical to use the short head cone crusher to form a closed circuit with the screen.
