Three factors affect the operation of vibration screen

Vibrating screen is a new type of multi-layer, high-efficiency vibrating screen with circular motion. It uses cylindrical eccentric shaft exciter and partial block to adjust amplitude, material sieve has long running line and many sieving specifications. Vibrating screen has the characteristics of reliable structure, strong exciting force, high sieving efficiency, low vibration noise, durability, convenient maintenance and safe use. It is widely used in mining, building materials, transportation, energy and chemical industries.

Performance advantages

1. Using cylindrical eccentric shaft exciter and bias block to adjust the amplitude is simple to use and convenient to maintain.

2. Vibrating screen adopts spring steel braided screen mesh or punching screen plate, which has long service life and is not easy to plug.

3. Structural reliability, strong exciting force, high screening efficiency, low vibration noise and durability.

4. Vibrating screen uses vibration motor as excitation source, which is easy to use and maintain.

Factors affecting the vibrating screen operation what factors influence screening process can be divided into the following three categories:

1. into the physical properties of screen material: including particle size composition, humidity, mud shape and particle.

2. the screen surface motion characteristics of structural parameters: including the characteristic extremely, the screen surface movement of the sieve length and width, the effective screen, screen size and shape.

3. operating conditions: including productivity and the size of the feeding uniformity etc.

In the above three factors, the first factor is not arbitrarily change in humidity. Second factors must be carefully considered in the design of the sieve. There are third kinds of factors can be adjusted in the actual production process. Many types of vibrating screen consists of several types of vibrating screen, in the mineral processing industry commonly used according to the structure and motion characteristics, can be divided into the following several types:

1) fixed screen: including the fixed sieve, sieve, fixed cantilever bar screen and arc sieve.

2) cylindrical sieve: a cylindrical sieve, sieve and sieve conical pyramid.

3) the plane shaking screen.

4) vibration sieve: mechanical transmission and power transmission two. The former is eccentric vibrating screen, vibrating screen, self centering vibrating screen, vibrating screen and resonance screen. The latter has electric vibrating screen.

sand making machine with different working principle

The performance of sand making machine directly affects the quality and output of sandstone products. In order to improve the grinding rate of sand machine, the equipment with good performance is the foundation. The adaptability of material performance and working parameters of sand making machine also determines the finished sandstone. An important factor. How to choose the sand making equipment, the selection criteria of different users are different according to the needs of customers.

In general, the whole center feeding is mainly made of stone iron, which is generally used to make sand with low output; while the central feeding with waterfall feeding is the combination of stone tapping iron and stone striking stone, which is generally used for shaping, with high yield.

It is suitable for medium hard materials with high abrasiveness, such as basalt. In the crushing process, the material ejected from the wheel has impact on the material lining, and does not directly contact with the metal components of the equipment, so as to reduce iron consumption and maintenance time. Under the working condition of stone striking, the grain shape of finished product is good.

It is suitable for medium hard and low abrasive materials, such as limestone. The crushing efficiency is high under the working condition of stone striking iron.

1. Performance of sand making equipment: the performance of equipment directly affects the quality of gravel, including the selection of equipment type and specification, and the combination of material properties.

From the model of sand machine, in addition to the traditional sand machine, there are different sand making equipment, their working performance is different.

In addition, different manufacturers have different levels of technical mastery of sand making machines. The performance of sand making equipment produced by different manufacturers will be different.

2. Material characteristics: the working parameters of sand making machine need to be adjusted according to the physical and chemical properties of materials. The higher the matching degree between the two, the better the working performance of sand making equipment, the better the quality of finished products and the higher grinding rate. If there is a big difference between the material parameters of the material and the working parameters of the sand making machine, such as the hardness and water content of the material, which are not suitable for the predetermined parameters of the sand making machine, the use of the grinding speed sand making machine will be greatly reduced.

3. Production environment: due to the source of materials and other reasons, the production environment of gravel aggregate is different and complex.

In the field of dry powder sand making, the requirement of sand making machine is very high. The material enters the crusher and is even subjected to two times of impact from the crusher and into the crusher. Materials are divided into 20 mesh or smaller. The material itself is crushed to reduce angular contamination. The hammer and lining in the sand machine are made of new wear-resistant material. As for limestone, the life of the hammer is about half a year, which reduces the cost to the customer.

Operating rules of sand making machine

According to the different scope of use and operation object, there are different types of sand making machine, such as impact sand making machine, vertical sand making machine, limestone sand making machine, etc. If we want these sand making machines to be able to produce efficiently, we must do some preparatory work.

1. Preparation for control of feeding granularity of sand making machine:

If the feed size is larger than the specified size, it will lead to the impeller imbalance, excessive wear of impeller, and even block the impeller and central feeding pipe, so that the sand machine can not work normally, and large pieces of material should be removed in time.

2. Preparation for trial operation of sand making machine:

The rotation direction of motor belt shall be consistent with that of sand making machine. If the direction is opposite to the label, the motor wiring should be adjusted, and the rotation direction should be consistent with the label. The number of V-belts connected to the spindle assembly is the same and should be adjusted straight. Check the correctness before production, and carry out empty machine test before production. After 8 hours of no-load operation, the production can be started after the test confirms that there is no problem.

3. Preparation of sand making machine lubricant:

Check whether the lubricating oil pipe of sand making machine is firm. Please add oil and special grease before trial operation. Check whether the lubricating oil pipe of the filling wheel is firmly connected, and carefully check whether there are foreign matters on the impeller. Every 100 hours of operation, the sand machine will be added with appropriate amount of grease.

4. Stop of sand making machine:

Stop feeding before the main machine of sand making machine stops running, otherwise the impeller will be crushed and the motor will be burnt out. During operation, there shall be no vibration and abnormal sound, if any, it shall be closed for inspection.

The prospect of new type sand making machine is very broad. Compared with the traditional stone processing equipment, the mobile sand making machine breaks through the traditional fixed operation mode and has a wide range of uses.

From the operation point of view, the new sand making machine adopts modern popular PLC control, and the high degree of automation can meet the requirements of modern industrial production. In terms of installation, the integrated components of the new mobile sand making machine are easy to install, and raw materials can be mined and transported, thus reducing disassembly and transition.

From the perspective of effect, the stone processed by the new sand making machine has uniform particle size and reasonable grading, which conforms to the national construction sand making standard. The market potential of new sand making machine is infinite, and the development of mechanical technology has brought more benefits to the industry.
