What is the spiral chute of belt conveyor
The spiral chute of the belt conveyor is an auxiliary equipment used in the belt conveyor system. It is usually installed at the discharge end of the belt conveyor. Its function is to guide the materials to be smoothly and evenly discharged from the belt conveyor to a certain position.

The spiral chute of the belt conveyor is an auxiliary equipment used in the belt conveyor system. It is usually installed at the discharge end of the belt conveyor. Its function is to guide the materials to be smoothly and evenly discharged from the belt conveyor to a certain position. The following is a detailed introduction of its structure and working principle:
1. structural features
Spiral chute is generally made of steel plate or other wear-resistant materials, and the overall structure is spiral. It is composed of a central axis and blades spirally rising or falling around the central axis, similar to a spiral pipe.
The inner diameter and outer diameter of the chute are designed according to the bandwidth of the belt conveyor, material characteristics and discharge requirements. Generally, the inner diameter is slightly larger than the width of the belt to ensure that materials can enter the chute smoothly. The outer diameter is determined according to the requirements of installation space and discharge angle.
The blade spacing and spiral angle of the spiral chute are also carefully designed. The blade spacing should ensure that the materials can be evenly distributed and flow smoothly in the chute. The spiral angle determines the movement speed and discharge direction of the materials in the chute.
2. working principle
When the material runs to the discharge end with the belt conveyor, due to the movement speed of the belt and the inertia of the material, the material will tend to be thrown forward. The spiral chute uses its spiral structure to gradually change the movement trajectory of the material along the direction of the spiral blade, so as to realize stable and uniform discharge.
The material is subject to gravity and centrifugal force in the chute. Gravity makes the material slide down, while centrifugal force makes the material move along the circumference under the action of spiral blades. The combined force of the two forces makes the material form a spiral motion track in the chute, so as to correctly unload the material to a certain position.
3. application advantages
Uniform unloading: it can make the materials evenly distributed in the unloading process, avoid the centralized accumulation of materials in a certain position, and is conducive to the subsequent material processing and transportation.
Reduce material damage: compared with the traditional unloading method, the spiral chute can keep the material in a relatively stable motion state during the unloading process, reduce the collision and friction between materials and between materials and unloading equipment, so as to reduce the damage rate of materials.
Reduce dust flying: the closed structure of spiral chute can effectively reduce dust flying during unloading, improve the working environment and reduce the harm of dust to the environment and the health of operators.
Flexible adjustment of discharge position: by adjusting the installation angle and screw parameters of the spiral chute, the discharge position and direction of materials can be easily changed to meet the requirements of different process flows and site layout.
