In industries such as chemical, building materials, and food, drum screening machines are key equipment for material screening. But when faced with numerous models and brands in the market, how to choose the right equipment? Today, we will help you clarify your thoughts from three dimensions: core requirements, key parameters, and purchasing skills. 1、 Clear screening requirements are a prerequisite

1. Material characteristics

The particle size, humidity, and viscosity of different materials vary greatly. For example, flour screening requires selecting a low-speed machine to avoid material heating; And the ore sieve requires a high wear-resistant screen.

2. Production requirements

Small laboratories can choose models with a diameter of less than 0.6 meters and a daily output of 1-5 tons; Industrial grade equipment should pay attention to the length and speed of the drum, and models with a diameter of 1.2 meters or more can meet the demand for a daily output of more than 10 tons.

2、 Comparison of key parameters

1. Drum diameter and length

The larger the diameter, the larger the screening area, suitable for coarse material screening; An increase in length can prolong the residence time of materials and improve screening efficiency. Suggest selecting the combination of "diameter 0.8-1.5 meters+length 2-6 meters".

2. Mesh material and mesh size

Ordinary materials can choose stainless steel mesh, which has high hardness and corrosion resistance; It is recommended to use woven mesh for viscous materials, as the mesh holes are not easily clogged. The selection of mesh size should be based on the particle size of the finished product, such as 80-120 mesh commonly used in flour screening.

3. Transmission mode

Belt transmission has low cost but is prone to slipping, suitable for small and medium-sized models; Gear transmission has high precision and is recommended for use in large equipment.

3、 Practical purchasing tips

1. Prioritize the convenience of replacing the screen mesh

Choose a quick release screen structure to reduce downtime for maintenance. Suggest conducting on-site testing to see if the installation of the screen mesh can be replaced within 5 minutes.

2. Pay attention to the matching degree of motor power

Excessive motor power will increase energy consumption, while insufficient power will affect the screening effect. Generally calculated as 0.5-0.75kW motor per square meter of screen mesh .

3. Conduct on-site inspections of production cases

Request manufacturers to provide screening videos or on-site visits for materials of the same type, with a focus on observing the noise (≤ 75 decibels) and dust leakage during equipment operation.

Summary: When choosing a drum screen powder machine, it is necessary to make a comprehensive judgment based on material characteristics, output requirements, and usage scenarios. It is recommended to first clarify the three core indicators of "processing materials - particle size requirements - daily production", and then compare the parameters and screen the manufacturers qualifications.
