As a commonly used screening equipment in the mining industry, the vibrating screen is in a long-term working state and the operation is also a fine operation, so there will be more or less problems. If the feeding is too slow, it will affect the screening efficiency of the vibrating screen. The reasons for the slow feeding of the vibrating screen and the adjustment methods have been introduced in detail below. Let’s take a look.

The reason why the vibrating screen feeds slowly

1. Vibration motor problem

(1) The motor power cannot reach or the motor power is normal but the speed is slow, and the 1500 rpm that cannot be used will also cause the feeding to be slow.

(2) The steering problem of the vibration motor: the steering of the motor is divided into two types: forward rotation and reverse rotation. Under normal circumstances, the steering of the two motors is in the opposite direction, but if the user connects the positive and negative poles incorrectly when the power is connected, it will cause When the motor rotates in the same direction, there will be a problem of slow or no material feeding on the screen surface.

(3) The problem of the installation position of the motor: There are three installation positions of the vibrating motor of the linear screen, which are the bottom, the two sides, and the upper part. If the vibration motor is installed close to the feeding port, the screen surface material will run for a certain distance and then the speed will decrease and stay on the screen surface.

2. The amount of screen cloth is too large

The excessive amount of cloth on the screen surface is also the reason for the slow feeding of the vibrating screen. When the screen is added, the load of the motor is also added accordingly, and there will be a problem of slow feeding.

As an important part of the tractor, the clutch must be reasonably matched to fully satisfy the use of the tractor clutch. It needs to be lubricated in the process of use. Then in the process of selecting lubricating oil, what should we do? to operate it?

We want to make high-quality lubricating greases from base oils, thickeners and additives. The performance of different types of greases with different grades of the same type is very different, and the allowable rotation limits are also different. Therefore, the tractor clutch must be clear when choosing!

1. The choice of diesel

Diesel is divided into light and heavy diesel, and agricultural tractors generally use light diesel. Light diesel oil is generally divided into No. 10, No. 0, -10, -20, -35 and other grades according to its freezing point. In order to save money, in many areas, apart from those who are engaged in transportation in the cold winter, they need to prepare -35 oil. Generally, they only need to prepare two kinds of diesel oil, 0 and -20, for agricultural production. Use No. 0 diesel in summer and No. 11 in winter. In other areas, the appropriate number of diesel can be selected according to the specific local temperature.

2. The choice of oil

Diesel engine oil is required for agricultural diesel engines. Diesel engine oil is divided into three types: No. 8, No. 11 and No. 14. Generally, use No. 8 oil in summer and No. 11 oil in winter.

3. Selection of gear oil

Gear oil is divided into 20th and 309th. 30 in summer; 20 in winter. Here to remind the owners of the machine, it is strictly forbidden to use engine oil instead of gear oil, or to mix diesel and kerosene in the gear oil, so as not to reduce its viscosity, weaken the lubricating performance, and accelerate gear wear.

We are all concerned about the output of the ball briquetting machine. If the output of the ball briquetting machine does not meet the requirements, then even saving energy is useless. Next, we will focus on how to increase the pressure of the ball briquetting machine and supporting facilities without changing. The output of the ball machine?

How to increase the output of the ball press

1. The composition of the pressed material, that is, the degree of adhesion is very important and is a key factor in determining the ball-forming effect and productivity. Therefore, before the ball is pressed, the material should be fully dry-mixed to ensure smooth production.

2. The material of the pressure roller is very important. The selected alloy steel material is too single, and long-term use will cause wear and tear, which will have a great impact on production efficiency.

3. The motor and deceleration device of the briquetting machine are also very critical, and a good motor and deceleration device can also indirectly increase the output.

Precautions for the operation of the ball press

1. During the production process of the briquetting machine, metal and stones should not be allowed to enter the inside of the machine, so as to avoid construction hazards and damage to the structure of the machine;

2. The particle size of the materials used in the briquetting machine must be kept within 3 mm, otherwise it will affect the production efficiency and quality, and also reduce the service life of the briquetting machine;

3. Before starting, it must be ensured that the inside of the machine is empty, and no material is allowed to start;

4. It is strictly forbidden for non-professionals to disassemble and modify the fuselage;

5. It is necessary to regularly maintain and maintain the ball press, and it is strictly forbidden to use it with faults to avoid unnecessary dangers and losses.

Free forging is a processing method that uses impact force or pressure to deform the metal freely in all directions between the upper and lower anvil surfaces, and obtains the required shape and size and certain mechanical properties without any restriction, which is referred to as free forging. The tools and equipment used in free forging are simple, versatile and low in cost. Compared with casting blanks, free forging eliminates shrinkage holes, shrinkage porosity, pores and other defects, so that the blanks have higher mechanical properties. Forgings are simple in shape and flexible in operation. Therefore, it has special significance in the manufacture of heavy machinery and important parts.

BASIC PROCESS OF FREE FORGING

The basic processes of free forging include upsetting, drawing, punching, bending, torsion, offset, cutting and forging.

Upsetting

A forging process that reduces the height of the blank and increases the cross-sectional area. The upsetting process is mainly used for forging gear blanks and round cake forgings. The upsetting process can effectively improve the blank structure and reduce the anisotropy of mechanical properties. Repeated upsetting and drawing can improve the morphology and distribution of carbides in high-alloy tool steels.

Upsetting mainly has the following three forms:

1. Complete upsetting. Complete upsetting is to place the blank vertically on the anvil surface, and under the hammering of the upper anvil, the blank will be plastically deformed with a height reduction and an increase in the cross-sectional area.

2, the end upsetting. After the billet is heated, one end is placed in a drain or mold to limit the plastic deformation of this part, and then the other end of the billet is hammered to make it upsetting. The upsetting method of the leaking disc is mostly used for small batch production; the method of upsetting the tire mold is mostly used for mass production. Under the condition of single-piece production, the part that needs upsetting can be heated locally, or after all heating, the part that does not need upsetting can be chilled in water, and then upsetting is performed.
