Selection criteria and performance evaluation method of industrial mixer

一、The selection standard of industrial mixing machine

1. Material characteristics:

(1) Physical properties: the density, particle size, viscosity and other characteristics of the material determine the difficulty of mixing and the best mixing method. For example, the material with small particle size and good fluidity is suitable for choosing a horizontal powder mixer, while the material with large particle size and poor fluidity is more suitable for a vertical powder mixer.

(2) Chemical properties: the chemical reaction characteristics of the material (such as stability and reactivity) will also affect the selection of the powder mixer. For example, for materials that may undergo chemical reactions, it is necessary to choose a powder mixer with good sealing and temperature control.

2. Mixing requirements:

(1) Uniformity: Different products and applications have different requirements for the uniformity of mixing. For occasions where high uniformity is required, a powder mixer with efficient mixing technology should be selected.

(2) Speed and temperature: Some applications may require rapid mixing or mixing at specific temperatures. At this time, a powder mixer with rapid mixing or temperature control function should be selected.

3. Process integration:

Compatibility: The mixer should be able to seamlessly integrate with other production equipment to ensure process continuity and efficiency. For example, if a mixer needs to be integrated with a conveyor belt or packaging machine, a mixer that is compact and easy to connect should be selected.

4. Cost and efficiency:

(1) Return on investment: When selecting the mixer, its purchase cost, service life and maintenance cost should be considered to ensure the economic benefits of long-term operation.

(2) Production efficiency: Choosing a powder mixer with high production efficiency can reduce the cost per unit product and improve the profitability of the enterprise.

5. Safety and Environmental protection:

(1) Safety performance: A powder mixer that meets safety standards and has safety protection measures should be selected to ensure the safety of the operator. For example, the explosion-proof powder mixer is suitable for use in explosive environments.

(2) Environmental performance: low noise, low energy consumption of the mixer helps to reduce the impact on the environment, in line with the concept of sustainable development of modern enterprises.

二、The performance evaluation method of industrial mixing machine

1. Mixing uniformity test:

(1) Sampling and testing: Regular sampling from the powder mixing machine, through the analysis of the distribution of each component in the mixture.

(2) Comparative analysis: compare the test results at different time points, analyze the changing trend of mixing uniformity to evaluate the performance of the powder mixer.

2. Production efficiency evaluation:

(1) Record data: In actual production, record the output, energy consumption and operation time of the mixing machine.

(2) Efficiency analysis: Calculate the real efficiency of the powder mixer according to the recorded data, and compare it with similar equipment.

3. Reliability analysis:

(1) Fault statistics: statistical mixing machine failure frequency, failure type and maintenance cycle data.

(2) Reliability assessment: Evaluate the reliability of the powder mixer according to statistical data, and determine whether improvements or replacement parts are needed.

4. Maintenance cost calculation:

(1) Cost analysis: comprehensive consideration of maintenance costs, replacement parts costs and daily maintenance costs.

(2) Long-term costs: Evaluate long-term operating costs and compare them to similar equipment to determine the best investment decision.

5. Security assessment:

(1) Safety inspection: Check whether the safety protection measures of the powder mixing machine are perfect, such as protective cover, emergency stop button, etc.

(2) Employee feedback: Collect feedback from operators to understand the actual operation convenience and safety of the powder mixing machine.
