At present, the commonly used vacuum feeding machines in our country are divided into electric feeding machines and pneumatic feeding machines, which can replace manual automatic feeding into equipment such as hoppers, reaction tanks, dryers, mixers, etc. They also have the function of automatic dust collection and dust removal. The conveying capacity of the conveyor is generally between 100-5000kg/h.
The main features of the vacuum feeding machine are:
1. The vacuum feeding machine consists of a vortex vacuum pump (without oil or water), a membrane filter bag filter, a compressed air backflushing device, a pneumatic discharge door device, a vacuum hopper, a stainless steel adjustable suction gun, a conveying hose, and other components.
2. The motor is powered by a vortex vacuum pump, which is oil-free, water-free, and maintenance free.
3. The entire conveying process is completed in a completely enclosed state, eliminating dust pollution.
4. The body is a modular structure, and the barrel body is connected with quick opening clamps, making disassembly and cleaning convenient and fast.
5. Low energy consumption, low noise, and convenient control.
6. Special S-shaped flanging is used between barrels to effectively prevent dust leakage

Which sifting machine is best for sifting flour?

Screening machine is the general term for all vibrating screening machines. There are many categories, such as linear vibrating screen, three-dimensional vibrating screen, drum screen, swing screen, air flow screen and other different screening machines.
Flour is a powdery material, and its particle size is generally not very small. It is very suitable for screening with a rotary vibrating screen. The rotary vibrating screen is used to screen flour finely, with moderate output. It can have up to five layers, with a diameter from 400 to 2000, can satisfy all types of customers. If the demand for screening flour is relatively large and has special properties, you can also use a straight row sieve. The straight row sieve is a vibrating screen that can discharge materials faster. Compared with the rotary vibrating screen, it is more suitable for large-scale flour screening. User.
Other sifting machine types can also be used according to your different screening needs. When using a rotary vibrating sieve to sift flour, you can use a multi-layer sieve. Generally, it is designed with 3 sieving surfaces. The first layer of sieving surface uses a round sieve with a diameter of 17~20mm. The screen mesh with holes is used to remove larger impurities; the second layer of screen surface uses a screen mesh with round holes with a diameter of 12~15mm, which is used to remove medium-sized impurities; the third layer of screen surface uses a screen mesh with round holes with a diameter of 2mm The screen is used to remove tiny impurities.
When screening flour, the screening machine can generally achieve high screening accuracy, large processing capacity, simple structure, low energy consumption, low noise, etc. At the same time, it is also a sealed operation to avoid dust diffusion and is suitable for streamlined operations.

Manual sieving method: i.e. sieving with a hand-held standard sieve, which requires constant tapping during sieving and has the disadvantage of being time-consuming and labor-intensive. The minimum size of 75 microns
Mechanical sieving method: the standard sieve according to the size of the sieve holes stacked into a sieve tower, installed on the vibration sifter, without manual participation in the sieve, can be automatically sieved, sieve size of the minimum 75 microns, there is a certain amount of noise.
Air jet sieving method: the use of negative pressure so that the air flow method so that the sample is sieved The disadvantage is that only a layer of sieving, sieving volume is small, the maximum sieving volume of 30 grams, sieving size of 20 microns minimum.
Sonic sieving method: the use of sound waves generated by the vibration of the sieve, sieve layer 8 layers, sieve size of the smallest 5 microns, the disadvantage of the relative volume of mechanical sieve instrument is slightly larger.

How effective is the screening?
The linear screen has a large screening area and high processing capacity, which can meet the output requirement of 6 tons per hour, and can screen out fine sand with a mesh size of 1.5mm.

How durable is the equipment?
The screen mesh and grid frame of the linear screen are made of stainless steel 304, which has good corrosion resistance and long life. The overall material of the inclined screw conveyor is carbon steel. After appropriate anti-corrosion treatment, it can meet the needs of long-term use.

How to adjust the inclination angle of the inclined screw conveyor?
The inclination angle of the inclined screw conveyor can be realized by adjusting the height of the screw conveyor support points on the support frame to adapt to different production needs.

Here are some specific steps and precautions when checking the motor condition of the vibrating screen:

Safe power off: Before checking the motor, make sure the vibrating screen is powered off to prevent electric shock or other unexpected situations.
Appearance inspection: Check the appearance of the motor, including whether the casing is intact, whether there is obvious damage or deformation, etc. Make sure there is no abnormality on the outside of the motor.
Connection check: Check whether the motor cables and connectors are intact, without breakage, wear or looseness. Make sure the cables are firmly connected and there are no exposed wires.
Insulation check: Use an insulation tester or multimeter to measure the insulation resistance of the motor. Make sure that the insulation resistance value meets the specification requirements to confirm that the insulation condition of the motor is good.
Bearing inspection: Check the condition of the motor bearings. Gently rotate the rotor to observe whether there is any abnormal noise, vibration or unsmooth rotation. If abnormalities are found, bearing maintenance or replacement may be required.
Temperature detection: Use an infrared thermometer or contact thermometer to measure the temperature of the motor. Make sure that the temperature of the motor does not exceed the rated range when it is running to avoid failure caused by overheating.
Lubrication check: If the motor has lubrication points, check the condition of the lubricating oil or grease. Ensure that the amount of lubricating oil or grease is sufficient and lubrication maintenance is performed according to the manufacturer's recommendations.
Operational test: Under safe conditions, reconnect the power and perform an operational test on the motor. Observe the motor's starting, running, and stopping process to check for any abnormal conditions or noise.
Please note that these steps are for reference only and the specific inspection steps may vary depending on the motor type and manufacturer. When performing motor inspections, it is best to refer to the equipment's operating manual or consult the manufacturer's guidance to ensure that inspections and maintenance are performed correctly and safely.

During the flour production process, material agglomeration is a common problem, which will affect the continuity and efficiency of conveying. To help you solve this challenge, we recommend a screw conveyor with a pipe diameter of 114mm.

Our screw conveyors provide excellent performance in flour conveying. By using a 114mm pipe diameter design, we are able to ensure smooth conveying of flour and adapt to your conveying height requirement of 1.8 meters.

To prevent flour from clumping, we added a grate to the conveyor hopper. The design of this grille can effectively filter out large pieces of material and ensure continuous delivery of flour. You can rest assured that our equipment will help you achieve efficient production line operations.

Our screw conveyors not only provide an efficient flour conveying solution, they are also durable. We use high-quality materials and advanced manufacturing processes to ensure the stability and long-lasting performance of our equipment.
