Hemp core powder vibrating screen

What is hemp core powder vibrating screen?

Hemp core powder refers to the powder of the medullary part extracted from the stem of hemp plants (such as hemp, flax, etc.). The stem of hemp plants consists of the outer bast fiber and the inner core pith. Hemp core refers to this part of the soft and porous internal tissue. After extracting the bast fiber, the remaining stem part is processed (such as crushing, drying, etc.) to obtain hemp core powder.

Hemp core powder vibrating screen is an industrial equipment specially used for separating and screening hemp core powder. Its core working principle is to use the exciting force generated by the vibration motor to make the hemp core powder jump on multiple layers of sieves with different mesh sizes, so as to achieve accurate classification of powders of different particle sizes.

Common hemp core powder vibrating screens can be equipped with multiple layers of sieves. For example, a 20-mesh coarse screen is used to remove larger impurities, a 40-mesh and 80-mesh medium screen is used to separate powders of different coarseness and fineness, and a fine screen above 100 mesh is used to obtain finer hemp core powder. By selecting the appropriate number of screen layers and sieve hole size (mesh number), the hemp core powder can be efficiently separated into the required particle size range to meet the needs of different application scenarios, such as industrial raw materials, animal feed additives, etc.

Function of hemp core powder vibrating screen

Hemp core powder vibrating screen is a mechanical equipment that uses the principle of vibration to separate and screen hemp core powder. Its main function is to classify and purify hemp core powder according to particle size to meet the needs of subsequent processing or application.

① For specific materials: This vibrating screen is specially used to process the powdered material obtained after the hemp core (usually the inner medullary part of the stem of a plant such as hemp or flax) is processed.

②Use vibration: The equipment generates vibration through a vibration motor or other excitation device, so that the hemp core powder jumps and moves on the screen surface.

③Achieve separation: Screens of different specifications are set on the screen surface. By controlling the aperture size of the screen, hemp core powders of different particle sizes can be separated, impurities, coarse particles or fine powders can be removed, and products with the required particle size range can be obtained.

Types of vibrating screens suitable for hemp core powder

Working principle of hemp core powder vibrating screen

The hemp core powder vibrating screen usually adopts the working principle of the rotary vibrating screen, with a vertical vibrating motor as the excitation source. The eccentric weights at the upper and lower ends of the motor convert the rotational motion into horizontal, vertical, and inclined three-dimensional motion, and transmit it to the screen surface.

The hemp core powder enters the equipment through the feed port and moves up, down, left and right on the screen surface. According to different screening requirements, the material passes through 1-5 layers of screening layers with screens of different mesh sizes. The screen cleaning device under each layer of the screen continuously hits the screen, so that the material can be screened smoothly. The materials of different mesh sizes pass through the screens of the corresponding mesh sizes of each layer or are discharged through the discharge ports set at each layer, finally achieving the purpose of screening or filtering.

Structure of hemp core powder vibrating screen

Hemp core powder vibrating screen mostly adopts circular or linear vibrating screen. The structure may be slightly different according to different process requirements, but the basic structure usually includes the following parts:

Screen box: It is composed of upper cover, middle cylinder and lower bottom. Multiple layers of screen (1~3 layers) are set inside the screen box to achieve coarse and fine classification

Screen system: It adopts fine mesh stainless steel woven mesh (such as 60~200 mesh), which is suitable for the particle size range of hemp core powder

Vibration motor: It provides exciting force to make the screen body produce three-dimensional or linear vibration, thereby affecting the movement trajectory of the material

Base and shock absorption system: The whole machine is connected to the base through rubber springs or spiral springs, which plays a supporting and shock absorbing role

Discharge port and receiving device: It is usually equipped with multiple discharge ports for discharging coarse powder and fine powder after grading and screening

Features of hemp core powder vibrating screen

High screening accuracy and good grading effect: It can be configured with multiple layers of screens to achieve synchronous grading of 2~4 materials of different particle sizes. The screening particle size can be controlled within the range of 80~200 mesh, which is suitable for most fiber powder applications.

Adapt to the characteristics of fiber materials: In view of the characteristics of hemp core powder that it is light, easy to entangle and easy to fly, it is often equipped with an ultrasonic vibration device to solve the problem of fine powder sticking to the net and blocking the net, and improve the screening efficiency.

High screening accuracy: Through reasonable structural design and parameter adjustment, it can achieve accurate classification of hemp core powder and reduce the mixing of coarse particles in fine powder or fine powder in coarse particles.

Adapt to different screening mesh ranges: You can choose a combination of screens with different meshes according to specific application requirements, such as a combination from coarse screens (such as 20 meshes) to fine screens (such as 100 meshes or more).
