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.

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.

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.

1. If this problem occurs when the newly purchased product is used for the first time, you should check whether the screen mesh of the rotary vibrating screen is at the same level as the outlet. If the screen mesh and the outlet are not level, it will cause the rotary vibrating screen to discharge The problem of slowness arises.

2. The second case is the adjustment of the motor angle. The angle of the eccentric block of the vibration motor of the rotary vibrating screen can be adjusted to change the trajectory of the material moving on the screen surface. The smaller the angle, the faster the material will spread out ;The larger the angle, the slower the material will spread out. Generally, the motor angle is adjusted to 35 degrees to 45 degrees. If the angle is above 45 degrees, there will be a problem of slow discharge, which is suitable for screening materials with less impurities.

The solution to the slow discharge of vibrating sieve

1. Increase the weight of the two heavy hammers

2. Change the included angle of the upper and lower weights

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
