Screw conveyors, commonly known as augers, use rotating screws to move materials along fixed casing grooves for conveying work. The screw conveyor is characterized by sealed transmission and simple structure. Screw conveyor is a continuous conveying equipment widely used in metallurgy, building materials, chemical industry, grain and mechanical processing departments.
A screw conveyor is a machine that uses a motor to drive a screw to rotate and move materials to achieve conveying purposes. It can be transported horizontally, obliquely, or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.

The sand making process is mainly divided into dry sand making and wet sand making. The dry sand making process has more advantages than the wet sand making process. Dry sand making is not limited by water sources and the environment, which greatly reduces production costs. Vibrating screens play an important role in the sand making industry.

Grain suction machine is a kind of machine for transporting powder or fine granular materials, which is widely used because of its advantages such as easy operation, large delivery capacity and cost saving. There are many grain suction machine products on the market, different machines are made of different materials, and the design will have some differences.

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.
