Screw conveyors can be used to transport white sugar. The screw conveyor is a common material conveying equipment that transports materials along pipes or troughs through the rotation of spiral blades.

White sugar usually comes in the form of granules or powder, and screw conveyors are suitable for conveying granules, powders and granular materials. The spiral blades of the screw conveyor can be designed and customized according to the characteristics of the sugar and the transportation requirements. Typically, screw conveyors are made of stainless steel to ensure food-grade hygiene and quality requirements.

It should be noted that when conveying sugar or other foods, the screw conveyor should comply with food hygiene and safety requirements. Regularly clean and maintain screw conveyors to ensure that they are not contaminated or contaminated during transportation to ensure food quality and safety.

If necessary, it is recommended to consult a professional engineer or supplier to obtain a customized screw conveyor solution to meet the specific requirements of sugar transportation.

Which screening machine is best for screening sand?

For sand screening, commonly used screening machines include vibrating screens, rotary vibrating screens, trommel screens and linear screens. The following are some commonly used screening machines for sand screening and their characteristics:

Vibrating screen: Vibrating screen is a common and economical and practical screening equipment. It separates the sand on the screen through vibrating motion. The vibrating screen can be suitable for screening medium-sized sand and has the advantages of simple structure, easy maintenance and operation.

Rotary vibrating screen: The rotary vibrating screen is an efficient screening equipment. Under the action of vibration, the sand rotates and vibrates on the screen to achieve separation of coarse and fine particles. The rotary vibrating screen has high screening efficiency, large processing capacity and good screening accuracy, and is suitable for screening fine particles or fine sand.

Trommel screen: A trommel screen is a device that performs screening by rotating screen tubes. The sand is separated and screened in the screen tube through the rotation and tilt of the drum. The drum screen is suitable for screening larger particles of sand and has the advantages of strong processing capacity and simple structure.

Linear screen: Linear screen uses vibration force to screen in a straight direction. It has high screening accuracy, large processing capacity and high efficiency, and is suitable for screening fine particles or fine sand, especially in high-precision screening applications.

Choosing a suitable screening machine depends on factors such as sand particle size, moisture content, screening requirements, and production scale. For general fine sand screening, rotary vibrating screens are usually a better choice, with higher efficiency and screening accuracy. If you are screening larger particles of sand, a trommel screen may be more suitable. Vibrating screens and linear screens can also be considered for use under different circumstances.

It is recommended that when selecting a screening machine, you should comprehensively consider the characteristics of the sand, screening requirements, production needs and economic factors, and consult a professional engineer or supplier to obtain the best screening solution.

High-frequency screen is a device that uses high-frequency vibration technology for solid-liquid separation. Compared with traditional vibrating screens, it has the following characteristics:
High-frequency vibration: The high-frequency filter screen uses high-frequency vibration technology. The vibrator generates high-frequency vibration that acts on the solid-liquid mixture on the screen, so that the solid particles are quickly separated on the screen.
Handling finer particle size: It can handle finer solid particles, usually particles below 10 microns, while the traditional 450 vibrating screen can usually only handle particles above 50 microns.
High separation efficiency: Under the action of high-frequency vibration, the high-frequency filter screen can quickly and efficiently separate solid-liquid mixtures, and the separation efficiency is higher than the traditional 450 filter screen.
Energy saving: Since the high-frequency filter screen has high separation efficiency and fast characteristics, its processing time is shorter, thus saving energy.
Reduce impurities: The high-frequency filter screen uses high-frequency vibration technology to quickly separate solid particles, thereby effectively removing impurities and improving the purity and quality of liquids.
Automatic cleaning: High-frequency filter screens are usually equipped with automatic cleaning devices, which can clean the screen regularly to ensure the normal operation of the equipment.

High frequency screen maintenance
1. When the equipment is operating normally, the feeding situation of the sieve should be frequently observed, and the frequency of feeding should be increased or decreased in a timely manner in order to improve the classification efficiency.
2. Because the screen has high classification efficiency, good dehydration performance, and high concentration of the screen volume, the fluidity of the slurry in the screen volume chute is poor and should be equipped with a water pipe.
3. The motor and control box must be strictly protected from water to avoid short circuit. The vibrator should be covered with a rubber plate to prevent water and slurry from falling in, causing short circuit and blocking the air gap.
4. Check at any time whether the bolts in various parts are loose and whether the screen frame collides with the chute, etc.
5. The excitation current and amplitude can be adjusted according to the requirements of on-site operations. Achieve different screening effects.

Clean according to the actual situation. The remaining dust particles should be scrubbed with a soft brush first. Special residues should be washed with dilute acetic acid. If it is a metal frame or copper wire mesh test sieve, a special cleaning agent should be used.
The specific steps for cleaning the test sieve are as follows:
1. Turn off the power of the standard inspection sieve.
2. Loosen the fixing nuts at the two corners, remove the upper cover of the test sieve, and remove the sieve frame to be cleaned.
3. Use a vacuum straw and a rag to clean the remaining parts of the standard test sieve.
4. Use compressed air to clean the particles and powder on the screen. If the particles or powder are stuck in the screen holes and cannot come out, you can tap the screen lightly.
5. Install the small hole screen, large hole screen and upper cover in order.
6. Pack up the tools used when cleaning the standard inspection sieve and clean it.
Please note! When cleaning, do not press too hard on the grid to remove stuck particles, nor should you use sharp objects to clear blockages. To prevent the mesh from breaking.

1. The working principle of the swing screen is different from that of the rotary vibrating screen.
From the perspective of running trajectory, the swing screen is a nonlinear inertial vibrating screen, and its basic rotary motion is similar to manual screening. The material is evenly dispersed on the entire screen surface from the center to the outer edge, thereby spreading in the axial direction in a spiral motion. The fine particles thus complete the entire screening process. The rotary vibrating screen is a screening machine that performs three-dimensional circular motion, so the production sites required by the two screening machines are also different.
2. Different production output
If you want large output, it is recommended that you use a swing screen. If you want high precision, you need to use a rotary vibrating screen. This is because the area of contact between the screen surface of the swing screen and the material is large, while the usable area of the rotary vibrating screen is smaller. A larger contact part between the screen surface and the material will effectively increase the product throughput, while a small contact part will effectively improve the screening accuracy.
3. Screening accuracy is different
Since the rotary vibrating screen performs three-dimensional motion, and the operation mode of the swing screen determines that the effective screening area is doubled, the screening accuracy can reach more than 95%.
4. Impact on raw materials
There is no doubt that the rotary vibrating screen uses the principle of vibration to screen materials. Due to the vibration, the appearance of the materials will be destroyed. Therefore, many granular crystalline and brittle materials are not suitable for screening by the rotary vibrating screen, such as chicken essence and rotary vibrating screen. MSG, sugar, cooked food, etc. The swing screen has a slight elliptical swing motion, does not use vibration, has little impact on the raw materials, will not damage the material shape, and further improves the material output rate.
5. There is a big price difference between the swing screen and the rotary vibrating screen.
As a standard product in screening equipment, rotary vibrating screens have been produced for decades. The technology is mature and the supporting equipment is complete, so the price-performance ratio is very high. As a new product, the swing screen is relatively complicated to make and the supporting equipment is not perfect, so the price is generally several times higher than that of the rotary vibrating screen.
