The installation requirements for screw conveyors are:
1. 20 days before the installation of the screw machine, the foundation should be well watered. This foundation should ensure sufficient stability of the screw machine during operation.
2. Before installing the screw machine, all parts should be thoroughly counted and various pollutants inside and outside should be cleaned.

3. The adjacent flange surfaces should be connected smoothly and tightly, and the misalignment deviation at the joints on the inner surface of the casing should not exceed 1.4mm.

4. Asbestos rubber plates are allowed to be placed between the casing flanges to adjust the accumulated error in the length of the casing and spiral body.

5. The nominal distance between the outer diameter of the screw and the casing is consistent

6. The suspension bearings of the screw conveyor should be reliably fixed on the lifting ears of the casing, and after connecting with adjacent screws, the screw rotation should be uniform. During installation, adjusting shims can be added between the suspension bearing support and the casing lifting ears to ensure that the coaxiality of the spiral axis meets the requirements

7. When the screw machine is single drive, the tail bearing blind cover should be opened, and the distance from the bearing end face to the blind cover should be measured to be less than 20mm.

8. The coaxiality between the main shaft of the screw machine and the reducer shaft should comply with the provisions of GB1184-80 "Regulations on Shape and Position Tolerances without Individual Tolerance Indications".
9. After the chassis of the screw machine is installed, tighten the foundation bolts.
10. Tighten all connecting bolts to a reliable level.
11. The cover of the screw conveyor should be installed in sequence, with a cover buckle installed at an interval of about 0.5m. The last cover at each overlap of the cover should have a cover buckle installed, and one to two cover buckles should be installed at both ends of the screw conveyor to ensure the sealing of the screw conveyor.
12. The dust collection port, feed port, and discharge port should avoid the overlap between the casing flange and the machine cover, and generally adopt on-site welding

Yes, a screw conveyor can be connected to a packaging machine. A screw conveyor is a device used for material conveying, which transports materials from one location to another through rotating spiral blades. A packaging machine is a device used to package and encapsulate materials. The two devices can be used in combination to achieve continuous material conveying and automatic packaging.

Connecting a screw conveyor and a packaging machine usually requires certain engineering design and adjustments to ensure coordination and smooth operation between the two. Here are some common connection methods:

Direct connection: Directly connect the discharge port of the screw conveyor to the feed port of the packaging machine, and adjust the height and position of the conveyor so that the material can smoothly enter the packaging machine for packaging.
Use a flipper: Install a flipper between the discharge port of the screw conveyor and the feed port of the packaging machine. The flipper can change the direction of the material so that it can smoothly enter the packaging machine.
Use a transfer platform: Set up a transfer platform between the screw conveyor and the packaging machine to transfer the material from the conveyor to the feed port of the packaging machine. This method is suitable for situations where the height or position of the conveyor and the packaging machine are inconsistent.
Regardless of the connection method, it is necessary to ensure the continuity and stability of the material to avoid blockage and material overflow. In addition, attention should be paid to safety and hygiene requirements to ensure the sealing and cleanliness of the connection to comply with relevant industry standards and regulations.

In the actual connection process, it is recommended to consult professional engineers or suppliers to design and install according to specific equipment and process requirements to ensure the effective connection and collaborative work of the screw conveyor and packaging machine.

Yes, linear vibrating screen can be used to screen phosphate. Linear vibrating screen is a common screening equipment, which is widely used in the screening process of granular materials in various industries.

The linear vibrating screen vibrates the screen surface through the vibration force generated by the vibrator, so that the granular material is screened on the screen surface. During the screening process, the material will pass through the screen holes according to different particle sizes, so as to achieve the purpose of separating particles according to different sizes.

For granular materials such as phosphate, the linear vibrating screen can select the appropriate screen hole size according to customer requirements to achieve the screening effect. Customers can screen out fine particles below 1 mm as needed to improve the quality of the finished phosphate.

In addition, if phosphate is corrosive, you can choose to use corrosion-resistant materials (such as 316 material) to make the contact parts of the linear vibrating screen to ensure the durability and stability of the equipment.

Therefore, the linear vibrating screen is an effective equipment for screening phosphate, which can help customers achieve accurate screening of phosphate particles and improve the quality of finished products.

Should I use an ultrasonic rotary vibrating sieve or a straight sieve to sift flour?
First, let us understand the working principle and advantages of ultrasonic rotary vibrating screen. Ultrasonic rotary vibrating screen is a device that uses ultrasonic waves and vibration force for screening. Through the action of ultrasonic waves, it can cause flour particles to vibrate at high frequencies on the screen, thereby achieving rapid and uniform screening. Ultrasonic rotary vibrating screen has the advantages of high screening efficiency, high screening precision, and simple operation. It can effectively remove small impurities in flour, and at the same time, it can also achieve precise control of the size of flour particles, making the quality of flour more stable.
However, in-line screening also has its unique advantages. The inline screen is a device that performs screening through gravity and the inclination angle of the screen. Its working principle is relatively simple and its operation is relatively convenient. The inline screen can achieve classification and screening of flour particles by adjusting the inclination angle of the screen. This screening method is suitable for situations where the size requirements of flour particles are not very strict. The screening efficiency of the straight screen may be relatively low, but its structure is relatively simple and the maintenance cost is low.
In summary, the choice of ultrasonic rotary vibrating screen or straight row screen should be decided according to the specific screening needs. If you have strict requirements on flour quality and particle size, and want to achieve efficient and accurate screening, then the ultrasonic rotary vibrating screen is a better choice. It can improve screening efficiency and ensure stable flour quality. If the flour particle size requirements are relatively loose and you want to save on equipment maintenance costs, then a straight screen may be more suitable. Of course, in practical applications, you also need to consider factors such as the price of the equipment, maintenance costs, production scale, etc., and comprehensively weigh all factors to choose the screening equipment that best suits your needs.

1. The bucket elevator should be driven with no load. Drain all materials in the hopper before stopping each time, and then stop.
2. it cannot be reversed. Derailment of the chain may occur when it is reversed, and it is very troublesome to troubleshoot the derailment.
3. Feed evenly. It is forbidden to increase the feeding amount suddenly. The feeding amount cannot exceed the conveying capacity of the elevator. Otherwise, it is easy to cause a "stuffy car" accident when the material at the bottom accumulates seriously.
4. Replenish lubricating oil in a timely and appropriate amount.
5. When the chain and hopper are severely worn or damaged, they should be replaced in time.
