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

High frequency dehydration vibrating screen

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.

At present, briquetting machine manufacturers basically have products of various specifications and models for users to choose from. Generally, the appropriate model is selected according to its own production capacity. But some customers have a misunderstanding about the size of the output, that is, only buying a larger briquetting machine can increase the output. So what are the factors that affect the output of the briquetting machine?

Factors affecting the output of briquetting machine

briquetting machine

1. The performance of the equipment itself is a key factor in determining the output of the briquetting machine. If you choose a briquetting machine, but because its quality is not good enough, there are often problems during use, so no matter what model you choose , are all useless. Therefore, the efficient operation and trouble-free operation of the briquetting machine equipment is an important condition to ensure production.

2. A single briquetting machine cannot be produced on a large scale, so many companies will build a briquetting machine production line, and the structure of the production line is also very complicated. In addition to the briquetting machine, there are also crushers, conveyors, dryers, etc. There are many kinds of machinery, so the production capacity of the briquetting machine alone is high, and the production capacity of other components cannot keep up.

3. Whether the connection between the various processes in the whole production process is smooth and efficient. This is a very delicate work. If any part of the production line is not running smoothly, the efficiency of the entire production will be affected. Therefore, in order to improve production efficiency, in addition to purchasing high-capacity equipment, other aspects need to be in place.

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.

The slope of the linear vibrating screen refers to the angle between the screen surface and the horizontal direction. This slope is related to the screening efficiency, because only if the slope is appropriate, the screening of the material can be more accurate. If the slope is too large, the material will be on the screen surface. The residence time will be short, although the discharge is easier, but the material is not carefully screened, if the slope is small, the material will stay on the screen surface for a long time, but the output per unit time will be low, so the slope of the linear vibrating screen is still To be within a reasonable range, what is the general slope of the linear vibrating screen?

What is the general slope of the linear vibrating screen

High frequency dehydration vibrating screen

The slope of the linear vibrating screen is generally between 0-15°. If you want to screen special materials, you can increase the slope, but it does not exceed 25°. The material of the linear vibrating screen equipment moves in a straight line on the surface of the screen. Generally, the screen of the linear screen will have a certain inclination angle to promote the flow of the material on the screen. The angle between the screen and the horizontal plane is the slope of the linear vibrating screen. Appropriate slope screening effect is better, not only can the material classification be clear, but also can screen efficiency, but in actual production, the installation slope of the vibrating screen should be adjusted according to the specific properties of the processed materials and the different output requirements, but this The process should also be strictly in accordance with the implementation of the vibrating screen manufacturer.

The slope setting of the linear vibrating screen is related to the material to be screened. The linear vibrating screen is suitable for screening non-viscous dry powders and granules with a moisture content of less than 7%. When the moisture content of the material increases slightly, the linear vibrating screen can adjust the slope appropriately.

The influence of the slope of the linear vibrating screen

Linear vibrating screen

1. Affect the screening efficiency

The slope of the linear vibrating screen will directly affect the efficiency of the vibrating screen. If the slope is too large, the residence time of the material on the screen surface is short, and it is easy to discharge, but it will cause uneven screening of the material and affect the screening fineness.

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.

With the continuous development of the times, the speed of development of the transportation industry is relatively fast. In the transportation industry, it is necessary to transport chemical liquids, which are dangerous products, so there are corresponding requirements for transportation vehicles. What are the advantages of chemical liquid transportation vehicles?

There are many advantages of chemical liquid transport vehicles. For example, it has anti-corrosion and anti-aging effects, which has a lot to do with the application material of the vehicle. Generally, these vehicles use advanced large-scale rotomolding equipment for one-time molding. Welds are non-toxic, have certain advantages in price, and have a long application cycle.

The chemical liquid transport vehicle does not leak during operation. We all know that to ensure its stability during chemical liquid transport, the choice of transport is very important. Many of these vehicles have the advantages of about 8 years of service life and low prices. It adopts the same shape as the oil tank separator, and the double-layer structure of each separator is rotomolded after welding with the tank body. Compared with the full-plastic separators in the same industry, the steel-plastic composite steel-plastic separators of the steel-lined plastic chemical tank trucks the process has three advantages:

/tank-truck

1. It can increase the strength of the tank by 3 times, and the partition will not collapse. All-plastic separator, because the separator is not welded to the tank body, it is fixed with 4 PP pipes to the head, which has little effect on the strength of the tank body. If the tank is not filled with liquid, it is easy to deform and collapse. Tank deformation, cracking and other problems.

2. Good stability and balance, because the separator has only one manhole with a diameter of 500mm, so the liquid flow is small. Generally, the vacancy gap of the all-plastic separator is half the size of the tank section. If the gap with a large section exceeds two-thirds, the vacancy gap is too large to cause unstable driving, and the poor balance is prone to traffic accidents.

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.

Agricultural machinery bearing sleeve

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.

Free forging is what we call free forging, which is completed by gradual local deformation of the blank on the flat anvil or between the tools. Because the tool is in contact with the blank part, the stagnant grid work is much smaller than the die forging bar for the production of forgings of the same size, so free forging is suitable for forging large forgings. Of course, free forging also has certain advantages and disadvantages in the forging process. Yes, let’s find out together!

Agricultural machinery lifting arm

THE ADVANTAGES OF FREE FORGING :

(1) Free forging can improve the structure and properties of metal. The quality and mechanical properties of metal free forgings are higher than those of castings, and their strength is 50% -70% higher than that of castings, so they can withstand large impact loads. Forgings can reduce the weight of the parts themselves on the premise of ensuring the design strength of the parts, which is of great significance to aerospace and transportation.

(2) Free forging can save raw materials. Parts with shapes closer to the part can be produced using the free forging method.

(3) Free forging is suitable for single-piece small batch production, and the variety is more flexible.

(4) Since there is no lateral flow in the straight shaft or curved shaft parts and annular parts, the streamline distribution is generally more reasonable than that of die forgings. It is especially suitable for straight or curved shafts, discs or rings with simple shape, small cross-section change and gentle main axis.

(5) Some special quality torsion requirements can be met by the free forging process, such as reverse upsetting can improve the quality of raw materials.
