1、 Core working principle: 3D convection and precise shearing

The performance of the horizontal screw belt mixer is rooted in its scientific mixing dynamics design. The core of the equipment consists of a U-shaped long cylinder and a stirring shaft that runs through it. The shaft is wound with a unique double-layer opposite direction screw belt.

Its working process is a precise combination of three-dimensional convection and shear:

1. Macro convection: The outer spiral belt pushes the material from both ends of the cylinder towards the central area, while the inner spiral belt transports the material from the central area towards both ends, forming a reverse convection of *.

2. Radial diffusion: Under the push of the helical blade, the material not only undergoes axial motion, but also generates complex radial flow, quickly breaking the composition gradient.

3. Micro shear: The unique open spiral structure can generate more vortices and local shear forces inside the material during rotation, which is crucial for breaking material agglomeration and achieving diffusion of trace components.

This composite motion mode of "convection+diffusion+shear" ensures rapid mixing of materials in three-dimensional space, which is fundamental to achieving high uniformity and high efficiency mixing.

2、 Key technological advantages and innovative design

The technological advantages of this series of devices are reflected in multiple aspects, directly responding to key pain points in industrial production.

1. Mixing uniformity and speed

The equipment can achieve uniform mixing of materials with a ratio of up to 1:10000, especially for materials with large differences in specific gravity (such as metal powder and resin particles), which has significant advantages. The actual test case shows that 1000 kilograms of flour and 5 kilograms of pigment can be mixed to a highly uniform state within 10 minutes. The single batch mixing cycle usually takes only 1-10 minutes, which is 6-10 times more efficient than traditional trough or vertical mixers.

2. Material adaptability and processing capability

·Wide adaptability: Designed specifically for mixing powders, particles, pastes, and viscous materials, it can easily handle the mixing tasks of solid solid and solid slurry (powder and gel liquid).

·Large loading capacity: The design loading factor can reach over 70%, the equipment space utilization is high, and the single processing capacity is large.

·Gentle processing: The mixing process is mainly based on convection, with controllable shear force, which can effectively protect the original crystal form or fiber structure of the material from damage, especially suitable for industries that require material morphology.

3. Structural design designed for cleanliness and safety

·Pollution free guarantee: All lubrication points are designed on the outside of the cylinder, eliminating the risk of oil contamination infiltrating the material. All internal welds are polished with smooth transitions and treated with polishing for easy cleaning, meeting the GMP requirements of the food and pharmaceutical industries.

·Fully sealed system: It can be equipped with a fully sealed structure, explosion-proof motor, and nitrogen protection interface, effectively preventing dust leakage and isolating air from entering, ensuring operational safety and suitable for mixing easily oxidizable, flammable, and explosive materials.

·Clean and residue free discharge: A unique (pneumatic) large opening discharge valve is installed in the middle of the bottom of the cylinder, which is flush with the inner wall of the cylinder and evenly mixed. During discharge, the screw belt continues to operate, sweeping the material to the discharge port with extremely low residue. In actual testing, the residue of 1000 kilograms of material after discharge can be less than 5 kilograms.

4. Convenient maintenance and energy-saving features

·Easy to clean: The cylinder cover can be designed as a fully open door, making it convenient for personnel to enter for cleaning and batch replacement, greatly reducing equipment cleaning time.

·Reliable operation: using cycloidal pinwheel reducer for direct connection or belt transmission, with stable structure, few vulnerable parts, and easy maintenance.

·Energy saving and efficient: The optimized power system is matched with an efficient hybrid mechanism, and the energy consumption per unit output can be reduced by about 15% -25% compared to traditional equipment.

3、 Flexible customized configuration plan

Longxing Group is well versed in the process differences of different industries and materials, therefore the WLH/LHY series provides highly flexible customized services to ensure equipment and production line compatibility.

Key customization options include:

·Heat transfer scheme: According to the process requirements, a jacket can be installed outside the U-shaped cylinder, and steam, thermal oil or cooling water can be introduced to achieve heating, insulation or cooling of the material.

·Discharge method: For powders, fine particles, or semi fluid materials, multiple discharge valve options are available, such as manual/pneumatic butterfly valves and pneumatic large opening doors.

·Loading and discharging system: It can integrate vacuum loading, dust-free feeding station, ton bag unloading, and closed conveying system to achieve full process automation and dust-free operation.

·Material and process: The main contact material can be made of 304, 316L stainless steel or other special alloys, and can be treated with mirror polishing, passivation, etc. to meet the requirements of corrosive materials or ultra-high hygiene standards.
