Key technical advantages and innovative design of horizontal screw belt mixer

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. The screw belt continues to operate during discharge, sweeping the material to the discharge port with extremely low residual levels. In actual testing, the residual amount 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.

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.

4、 Clear technical parameters and selection guidelines

For the convenience of customers' selection, the WLH/LHY series offers a standard volume range from 0.25 cubic meters to 10 cubic meters. Here is an overview of the technical parameters of some core models:

·Equipment weight: approximately 8900 kg

Selection suggestion: When selecting, it is important to consider material characteristics (specific gravity, viscosity, corrosiveness), process requirements (mixing uniformity standards, whether heating/cooling is required), production rhythm (batch time, production capacity requirements), and workshop conditions (space, floor height). Suggest having in-depth communication with Longxing technical engineers to design personalized solutions.

5、 Quantifiable Economic Benefit Analysis

Investing in a horizontal screw belt mixer is not only an equipment upgrade, but also a cost reduction and efficiency improvement investment. Based on comprehensive customer feedback, its economic benefits are mainly reflected in:

1. Direct cost reduction: Energy saving of 15% -25%, while reducing rework and waste caused by uneven mixing.

2. Efficiency improvement: The mixing cycle is shortened several times, and the production capacity is significantly increased within the same time, diluting fixed costs.

3. Labor saving: Automation and easy to clean design reduce human involvement, lower labor intensity and labor costs.

4. Loss reduction: The extremely low residual rate of materials is of great significance for processing high priced raw materials such as pharmaceutical intermediates and pigments.

According to a pigment production company's calculation, the comprehensive savings in electricity costs, material losses, and labor costs can recover the equipment investment cost within 18 to 24 months.

6、 Extensive and in-depth application industry practices

The universality and reliability of this device make it a standard configuration in many fields:

·Chemical industry: used for mixing powders and slurries of dyes, pigments, coatings, resins, pesticides, compound fertilizers, etc. Its sealing and explosion-proof design ensures safe production.
