The core of selecting a suitable screening machine is to match equipment parameters around material characteristics, screening requirements, and usage scenarios. The following are the key selection logic and steps:

1. Clarify the core screening requirements

Determine the screening purpose, whether it is grading, impurity removal, or filtration, and specify the required number of screening grades (single-stage/multi-stage).

Clarifying the feeding particle size and target discharging particle size is the basis for selecting the sieve aperture and equipment type.

Confirm the hourly processing capacity to avoid insufficient equipment capacity or excessive redundancy.

2. Analyze the key characteristics of materials

Material status: vibrating screen is preferred for dry materials, while ultrasonic vibrating screen and drum screen can be considered for wet or viscous materials.

The specific gravity and hardness of the material require the selection of equipment with a sturdy structure and strong excitation force for materials with high specific gravity or hardness.

Powder content and flowability. For high powder content, models with good sealing performance should be selected. For poor flowability, equipment with higher vibration motor power can be used.

3. Match device types and scenarios

Vertical or small vibrating screens are preferred for limited space, while drum screens and large linear vibrating screens can be considered for open spaces.

Continuous operations prioritize linear vibrating screens and circular vibrating screens, while intermittent operations can use fixed screens or small experimental screens.

Industry specific requirements require the selection of stainless steel materials and easy to clean models for the food and pharmaceutical industries, and wear-resistant and impact resistant equipment for the mining and coal industries.

4. Verify key equipment parameters

The material and aperture of the screen mesh are selected based on the hardness and particle size of the material. For wear-resistant materials, manganese steel screen mesh is chosen, and for fine screening, stainless steel woven screen is selected.

Vibration frequency and amplitude, fine materials require high frequency and low amplitude, while coarse materials require low frequency and high amplitude.

Installation method, choose seat type, suspension type or mobile type according to site conditions.
