The finished coffee powder needs to be screened and graded through a linear vibrating sieve. Finally, it needs to be filtered and sieved through an ultrasonic rotary vibrating sieve. Ultrasonic rotary vibrating screen is installed on the basis of ordinary rotary vibrating screen with a low-amplitude, high-frequency ultrasonic vibrating screen (mechanical wave), which can effectively solve the problem of materials due to strong adsorption, friction, static electricity, high precision, high density, light specific gravity, etc. features. Network congestion occurs. Especially suitable for high-quality, fine powder users.Everyone is familiar with coffee powder. The coffee tree is an evergreen small tree belonging to Rubiaceae, native to Ethiopia. Tropical and subtropical evergreen small trees or shrubs. Long oval leaves, white flowers, dark red berries. There are small fruit, medium fruit, large fruit coffee and so on. After the seeds are fried and ground, they can be turned into powder to make beverages, which have excitatory effects. The production process of coffee powder is as follows:
1. Screening: First, use a linear vibrating screen to separate the sand, soil and sundries in the coffee.
2. Roasting: Roasting on a coal stove at 130-160°C, strictly controlling the temperature to prevent carbonization.
3. Finishing: In the roasted coffee beans, add 0.2% Luzhou Tequ and simmer for a few minutes.
4. Hulling and crushing: After the coffee beans are peeled off their shells, they are crushed by a grinder.
5. Impurity removal: The crushed coffee powder is screened through a 100-mesh ultrasonic vibrating sieve. Filter out finer particles.
1. Ultrasonic vibrating screen for coffee powder completely solves screening problems such as strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity;
2. Effectively reduce or even eliminate screen cleaning time, effectively reduce screening times, and greatly improve screening efficiency;
3. During the screening process, no bouncing balls and other auxiliary materials will pollute the powder;
4. After several improvements, the energy conversion efficiency of the ultrasonic vibrating screen transducer is high, leading the industry standard, and has reached the foreign counterpart standard;
5. The wave band output by the numerical control power supply is transmitted to the surface of the screen through the transducer at 360,000 times/minute;
6. Compared with ordinary vibrating sieves, the screening accuracy of angelica powder ultrasonic vibrating sieves can be increased by 1-100%, and the output can be increased by 1-15 times.
7. It can effectively screen 25μm powder and filter 10μm liquid;
8. It can be used in single or multiple layers, and a set of intelligent ultrasonic generator uses three transducers at the same time;
9. While achieving high-precision and high-mesh screening, it can effectively control the concentration of particle segments;
10. The unique screen design of coffee powder ultrasonic vibrating screen has self-cleaning function. When >500 mesh is sieved, there is no mesh blockage, no screening efficiency attenuation, high signal uniformity, and longer service life of the screen.

When the material is prone to dust explosion, when the material is flammable and explosive solid matter and gas, an explosion-proof motor must be used when the sieved material is washed into flammable and explosive gas Case: carbonyl iron powder, carbonyl nickel powder (required for sieving Inert gas protection), sulfur powder, magnesium powder, zinc powder, aluminum powder, military powder, paint, oily pigment, etc.

The production and processing of sand and gravel generally go through the process of crushing, conveying, and screening, and the vibrating screen is helping the screening of gravel. To provide users with sand and gravel with an ideal particle size, the vibrating screen completes the screening work through the exciting force brought by the vibrating motor. Today, I will explain the application of vibrating screens in crushing stone processing.

In the manufacturing and processing of mining, chemical industry, abrasive, food industry, agriculture, construction industry, etc., the vibrating screen is a very common screening machine, which has caused problems during the operation of the machine due to improper use or other reasons. series of questions.

The occurrence of this phenomenon is mainly related to factors such as high solid content in the drilling fluid, high mud viscosity, and dispersion of drill cuttings, etc.; it is related to the small vibration force of the vibrating screen, high mesh number, and small screen area. It is related to its own conditions; it also has a lot to do with the direction and position of the liquid inlet of the vibrating screen during on-site installation. You can analyze it step by step from the following points

Ultrasonic vibrating screen is an ultrasonic energy conversion device attached to the working mesh surface of the ordinary three-dimensional vibrating screen, so that ultra-high frequency vibration energy is superimposed on the working mesh surface, thereby maintaining the smoothness of the screen mesh, and achieving a more ideal screening situation.
