What does a crusher do?

Question 1: What does a shredder in an electronics factory do? What is raw material processing, primary raw material crushing or primary processing? If it is in the later stage of the production line, it is the type of work that products are processed, crushed and destroyed.

Question 2: Urgent: What is the crusher in the coal chemical industry mainly responsible for? Is work particularly tiring? (Be specific, not general) Coal does not need to be broken. Generally, pulverized coal is ground by a coal mill, which is completely enclosed, so there will be no dust in the environment, and once it is produced, there is a danger of explosion. What I know is that desulfurization in chemical plants requires limestone crushing. There are also girls, and the environment is almost poor. Nowadays, there is little manual operation in industrial production, so it is generally not too tired.

Question 3: Do you know what the Xuzhou polysilicon crushing workshop does? Are you tired? Whether there is any hazard requires high cleanliness, and gloves must be worn for testing. Silicon wafer is fragile and easily broken, so be careful when operating.

No harm to the body, if the examination room can't smell the potion during the process.

Whether you are tired or not varies from person to person. Some people are tired after shouting to do something, and some people are not empty all day, but still feel quite full. Some leaders are watching or their posts are vacant, not necessarily.

Question 4: Hello, what does the crusher of Jinshan Bridge polysilicon mainly do? What kind of job? I went in for an interview from an intermediary company, except for the intermediary fee. ... 30 minutes, all I know is that the crushing workshop is very tired.

Question 5: Is crusher a special type of work for nonmetallic mineral companies? Hello, the crusher of nonmetallic mine is not a special type of work, which is not in the catalogue of special types of work.

Reply of the State General Administration of Labor to the Ministry of Metallurgical Industry on Early Retirement of Metallurgical Industry

Your job is not within the scope of early retirement in metallurgical industry.

The special type of work of the enterprise shall be implemented according to the relevant documents submitted by the competent department of industry to the Ministry of Labor for approval. There is a list of special jobs in the file reply. Some jobs in the list are special jobs, but jobs not in the list are not special jobs. Labor departments at all levels and enterprise labor departments hold such documents, and special types of work cannot be implemented by reference among industries, but only by industries.

Question 6: What are the economic subsidies for workers engaged in plastic crushing according to the labor law? Hello.

No matter what enterprises and units should recruit people according to the labor law, you also need to use the law to safeguard your legal rights. In this society, only you can safeguard your own interests.

It is necessary for the unit to pay five insurances, and the rest depends on the treatment of the unit.

Question 7: What is the working principle of the crusher? The working principle of different types of crushers is different. The following are the working principles of several crushers, which I hope to adopt. Sunway Heavy Industries.

1) The heavy hammer crusher can adjust the gap of the grate teeth in the machine according to the user's requirements, and change the discharging granularity to meet the different needs of users. The main working part of this machine is the rotor with hammer (also called hammer). The rotor consists of spindle, disc, pin shaft and hammer. The motor drives the rotor to rotate at high speed in the crushing cavity, and the material enters the machine from the upper feed inlet, and is crushed by the impact, impact, shearing and grinding of the high-speed hammer. There is a sieve plate at the lower part of the rotor, and the particles smaller than the sieve hole size in the crushed materials are discharged through the sieve plate, while the coarse particles larger than the sieve hole size are left on the sieve plate, and are continuously hit and ground by the hammer head, and finally discharged from the crusher through the sieve plate.

2) Hammer crusher mainly relies on impact energy to complete the operation of crushing materials. When the hammer crusher works, the motor drives the rotor to rotate at high speed, and the materials enter the crusher cavity evenly. The high-speed rotating hammer impacts and shears the material, which breaks it. At the same time, the gravity of the material makes the material rush from the high-speed rotating hammer to the baffle and screen bar in the frame, and the material larger than the screen hole size is left on the screen plate, and continues to be hit and ground by the hammer until it is crushed to the required discharging granularity, and finally discharged from the screen plate machine.

3) Impact crusher is a crusher that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at high speed, and the material enters the plate hammer action area and collides with the plate hammer on the rotor and is crushed, then it is thrown to the impact device and crushed again, and then bounces back to the plate hammer action area from the impact liner and crushed again. In this way, the materials enter the first, second and third impact chambers in turn from large to small, and are repeatedly crushed until the materials are crushed to the required particle size, and then discharged from the discharge port. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the particle size and shape of the material. Stones fall directly from the upper part of the machine into the high-speed rotating turntable; Under the action of high-speed centrifugal force, it collides with another part of flying stones distributed around the turntable in an umbrella shape at high speed and is crushed at high density. After the stones collide with each other, they will form eddy motion between the turntable and the shell, causing repeated collision, friction and rolling, and then directly discharged from the lower part. A closed loop is formed for many times, which is controlled by screening equipment to achieve the required particle size.

Question 8: What is the name of the person who does auxiliary production work such as packaging, batching and crushing waste in the workshop? 20 points. That's the workshop assistant.

Many names.

A handy man

Universal worker
