Introduction of Small Screw Conveyor Systems
Small screw conveyor systems are designed for users and laboratory applications with small volume, which can reliably and accurately convey various powder and granular materials in a very small footprint. Small Screw Conveyor Systems are mainly used to add minerals to products, and can also be used to add other preparations, which can be used in feed, food processing, pharmaceutical, chemical industry and other industries. Adding range: 0-100g/h, 100-1000g/h, 1-5Kg/h, 5-10Kg/h, 10-30Kg/h, 100-1000Kg/h.
The length of Small Screw Conveyor Systems is generally 200mm-1000mm, and carbon steel, stainless steel (304/316L) or plastic materials can be selected. The barrel part of the hopper can also open the observation window as required to facilitate the observation of material flow.
Systematic delivery solution
The small screw conveyor system can be matched with a variety of equipment to optimize material transportation and improve operating efficiency. Here are some examples of equipment that can be used with small screw conveyor systems:
Hopper: It can cooperate with the hopper to provide a stable material supply for the conveyor. Hoppers are designed to meet the specific needs of the application, such as capacity and discharge height.
Chute: It can cooperate with the chute to adjust the material flow of the conveyor.
Vibrating feeder: It can be matched with the vibrating feeder to provide a stable material supply for the conveyor.
Storage silo: It can be used with the storage silo to provide a storage solution for the conveyed materials.
Weighing system: It can be matched with weighing system to accurately measure the quantity of conveyed materials.
Dust removal system: It can be matched with a dust removal system to capture dust and other airborne particles generated during material handling.

How do I determine the proper pitch and diameter for a small screw conveyor system?
The proper pitch and diameter for a small screw conveyor system depends on several factors, including the material being conveyed, required capacity and operating conditions.
Material characteristics: such as particle size, density and fluidity of the material. These characteristics affect the amount of material the screw can convey and the power required to operate the conveyor.
Capacity requirements: Larger diameter screws generally have higher capacity than smaller diameter screws, but the pitch of the screw also affects capacity.
Operating conditions: such as screw speed, inclination angle, ambient temperature, etc. These conditions affect the power required to operate the conveyor as well as the wear on the screws and other components.
Usage of Small Screw Conveyor Systems
Small screw conveyor systems are used to uniformly feed non-viscous powder, granular and small granular materials from silos and other storage equipment to the receiving equipment. At the same time, they have the functions of conveying, sealing, homogenizing and stirring. Common equipment used in cement raw meal homogenization and silo sealing feeding. The specifications are generally: Ф100mm, Ф120mm, Ф150mm, Ф200m, Ф250mm, Ф300mm, Ф350mm, Ф400mm, etc. The production materials can be divided into: carbon steel and stainless steel, the specific specifications and lengths can be customized according to user requirements.
Small screw conveyor systems for plastics and chemicals
Small screw conveyor systems provide a good solution for corrosive or toxic plastic additives and chemical preparations. It can provide stable and accurate preparations or additives, with less residue after sealing, which is safer and more efficient than manual addition.
Small screw conveyor systems for pharmaceutical and food
Precise ingredients are needed to maintain the efficacy of medicines and the deliciousness of food, and of course safety cannot be ignored. Small screw conveyor systems made of 304/316L material can accurately feed materials at a speed as low as 32 g/h, while ensuring safety, non-toxicity and no pollution.
Small screw conveyor systems for classrooms or laboratories
Small and delicate is the primary and intuitive feature of Small screw conveyor systems. The weight can be as light as 25kg, saving space on the desktop. It can be used in laboratory for proportioning experiments or as a mechanical teaching tool in classrooms and chemistry classrooms.
Features and Benefits
1. The conveying capacity is between 3-22 cubic meters per hour, which is suitable for continuous feeding of small batches of powdery materials.
2. Small diameter and fast rotation speed can ensure uniform transportation of materials, and materials are not easy to be blocked. A loading and unloading gate can also be installed to control the flow of materials.
3. During the conveying process, the materials can be stirred, mixed, heated and cooled.
4. The whole conveying work is carried out in the pipeline, which avoids the pollution of dust to the environment and improves the working conditions at the same time.

Structure of the Small Screw Conveyor Systems
Small screw conveyor systems are generally composed of: silo, conveying pipe, screw shaft, bearing seat, coupling, motor reducer, control box, material level meter, vibration device, etc.; according to the customer's use, the above can be reduced or increased Components to meet customer use requirements
1. Silo: The volume ranges from 1L to 1000L, which can be round or square; it can be open or covered, and a seal can be set; when the volume of the silo is large, it is generally necessary to add or reduce weight cones to prevent the material in the silo. The weight is pressed on the screw shaft, which increases the load and affects the normal operation.
2. Conveying pipe: It is composed of steel pipe, inlet and outlet, end flange, etc. The diameter of the conveying pipe varies from 20mm to 500mm
3. Screw shaft: It is the main conveying component. The outer diameter and lead of the blade are matched with the appropriate rotation speed to meet the requirements of different conveying volumes.
4. Bearing seat: In order to support the screw shaft, two-end support can be used, or one-end support can be used. When one end is supported, it is a cantilever shaft structure, and the conveying length is limited to a certain extent.
5. Coupling: It plays the role of transmitting torque, and there are many ways, generally in the form of plum blossom elastic coupling, cross slide coupling, hollow bushing, etc.
6. Motor reducer: there are various forms of reduction motor, G series gear reducer, RV reducer, cycloidal pinwheel reducer, hard tooth surface gear reducer
7. Speed regulation control box: speed regulation by capacitor, frequency conversion, excitation speed regulation, etc., and there are also methods of speed regulation by mechanical stepless transmission
8. Material level gauge: 1-2 material level gauges can be installed on the silo as needed to detect the material level of the silo and achieve the purpose of automatic control. The material level meter can adopt the resistance rotary type, the proximity switch, the photoelectric sensor, etc.
9. Vibration device: In order to prevent the material from arching and bridging in the silo, a vibration percussion device can generally be installed on the silo. Commonly used vibration motors, pneumatic hammers, pneumatic pads, etc., can also be added in the silo. Arch device.
Available Options
1. It can be equipped with speed regulating motor and explosion-proof motor
