Detailed explanation of the process principle of the upward rotating screening machine
Date: 2025-01-06Read: 7
A screening machine is a device that screens solid particles through mechanical motion, commonly used in the production of solid preparations such as tablets, granules, etc. The upward rotating screening machine is a common type of screening machine, and its process principle mainly includes the following aspects:
1. Screen plate: The screen plate is the main component of the screening machine. The sieve plate of an upward rotating screening machine is usually circular or square, with a mesh screen or sieve holes installed on top, used to screen out products of the target particle size.
2. Motion: The motion modes of the upward rotating screen machine mainly include vibration and rotation. Vibration causes the raw materials to undergo rolling motion on the sieve plate, thereby increasing separation efficiency, while rotation evenly distributes force on the surface of the sieve plate, reducing the degree of wear on the sieve plate.
3. Screen: The screen is one of the key components of the screening machine. The screen mesh of the upward rotating screening machine is usually made of stainless steel material, and its fineness can be adjusted according to production needs. Choosing a suitable sieve can effectively screen out products with the target particle size.
4. Power system: The upward rotating screen machine usually uses an electric motor as a power source to cause vibration or rotational motion of the screen plate. The power and speed of the motor can be adjusted according to production needs.
Based on the above aspects, the equipment process of the upward rotating screening machine mainly includes four stages: vibration, rotation, screening, and discharge. The following will introduce them separately.
Detailed explanation of equipment process:
1. Vibration
The vibration of the upward rotating screening machine refers to the rolling and upward rotation motion of the screen plate under the action of mechanical vibration. The frequency and amplitude of vibration can usually be achieved by adjusting the parameters of the motor. Vibration can cause the raw materials to form distinct layers on the sieve plate, thereby increasing screening efficiency.
2. Rotate
The rotation of the upward rotating screen refers to the movement of the screen plate rotating around the central axis. Rotation can make the surface of the sieve plate uniformly stressed, reduce the degree of wear of the sieve plate, and also avoid the phenomenon of material layering in the axial direction. The angular velocity and direction of rotation can also be achieved by adjusting the parameters of the motor.
3. Filter
The screening of an upward rotating screening machine refers to the process of separating raw materials into products of the desired particle size on a sieve plate. The efficiency of screening is mainly related to the fineness of the sieve and the vibration and rotation conditions of the sieve plate. Generally speaking, the higher the efficiency of screening, the more refined the target products will be.
4. Discharge material
The discharge of the upward rotating screening machine refers to the process of discharging the screened target product from the screen plate. Generally speaking, there are two main ways for the discharge of upward rotating screening machines: natural discharge and manual discharge. Natural discharge refers to allowing the product to naturally slide into the collector below and be discharged through the effect of gravity. Manual discharge requires workers to remove the product from the sieve plate and perform subsequent processing.
