What is the difference between a screw classifier and a screw conveyor

Spiral Grader, Screw Conveyor - Intimate Partner Spiral Grader, Screw Conveyor - Close Partner:

There are four main types of spiral classifiers: high weir single spiral and double helix, sunken single spiral and double helix. The classifier is widely used in the concentrator with the ball mill to form a closed-circuit cycle to divide the ore sand, or used in the gravity concentrator to classify the ore sand and fine mud, and the metal beneficiation process to classify the particle size of the slurry, and the desliming and dewatering operations in the ore washing operation. The classifier has the characteristics of simple structure, reliable work and convenient operation.

Introduction to screw conveyor:

The screw conveyor series has a wide range of applications in the conveying of various powdery or granular materials. The screw conveyor is made of carbon steel with a finishing finish on the surface. The conveyor consists of the following parts:

A U-shaped or V-shaped groove body assembled with at least one discharge port, baffles at both ends of the tank, spiral blades welded to the central tube, connecting bushings at both ends of the central pipe, two end bearing assemblies including a shaft sealing unit, and an intermediate hanging bearing with a number determined by the total length of the screw conveyor and the cross-sectional area of the bolted groove. In addition, to meet the needs, the screw conveyor is also equipped with a reduction box and a motor. According to the different materials to be conveyed, the screw conveyor is designed with three models: light load heavy duty, medium load heavy duty and super heavy duty heavy load.

Most of the conveyors in the grain machinery and equipment are still familiar, after all, it replaces the original manual handling, and the distance and efficiency have been improved a lot. So what's the difference between a belt conveyor and a screw conveyor? The belt conveyor is more widely used in the market, and the belt conveyor has a wide range of applications and can be used in various fields such as industry and agriculture.

Of course, there is a big difference between the two in appearance.

1.The method of conveyor is different: the screw conveyor can be conveyed in any direction, and the belt conveyor is a horizontal linear or linear conveyor.

2.The way of conveyor is different, the screw conveyor is auger conveyor, and the belt conveyor is linear conveyor.

3.The mechanical mechanism of the conveyor is not the same, the screw conveyor is dust-free due to pipeline transportation, the use is more environmentally friendly, and the bulk material transportation is required, and the belt conveyor has strong conveying capacity, can be packaged and transported, and the structure is simple and easy to maintain.

The two are also different in terms of transportation volume, and the above is the difference between the screw conveyor and the belt conveyor, which is for reference only. The newly designed belt conveyor, also known as the environmental protection conveyor, is transformed on the basis of the traditional belt conveyor, and the customer response is good.

There is a difference between a screw conveyor and a belt conveyor. (One is conveyed with a spiral and the other is conveyed with a belt).

The screw conveyor can only transport bulk grain and bulk materials, and the belt conveyor can be used for bulk grain.

What difference are you referring to?

If it refers to the conveying method, of course there is a difference;

If it refers to the conveying effect, it should be distinguished from the fighting.

1. The conveying method is different: the screw conveyor is a rotary conveyor: the belt conveyor is a linear or linear conveyor.

2. The method of conveying is different: the screw conveyor can be conveyed in any direction: the belt conveyor can only be conveyed in a straight or linear direction in a nearly horizontal direction.

3. The mechanical structure is different.

There is a difference, the working principle of the screw conveyor is divided from the perspective of the displacement direction of the conveyed material, the screw conveyor is divided into two categories: horizontal screw conveyor and vertical screw machine, mainly used for the horizontal transportation and vertical lifting of loose materials such as various powders, granules and small blocks, the machine is not suitable for conveying deterioration, viscosity, easy to agglomerate or high temperature, afraid of pressure, and has greater corrosive special substances.

The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, can easily implement programmed control and automatic operation, and the belt conveyor uses the continuous or intermittent movement of the conveyor belt to convey items below 100kg or powdery and granular items. Its movement is high-speed, smooth, low-noise, and can be transmitted up and down hills.

The retractable belt conveyor is to add a telescopic mechanism to the ordinary belt conveyor, so that the belt conveyor can be freely expanded and contracted in the length direction.

Screw conveyor.

The screw conveyor, also known as the tubular screw conveyor and the single-pipe screw feeder, is mainly composed of a screw cylinder, a screw shaft and a screw sheet. The material passes through the feed hopper to the screw, the motor drives the screw shaft to rotate through the reducer, and the screw shaft rotation drives the material forward. The material continuously enters the spiral, and the material is constantly pushed between the material and the material from the discharge port, so as to realize the horizontal and inclined conveying of the material.

Screw conveyor features.

1.The driving device adopts gear reducer, with large torque, low noise, no oil seepage, long life, the conveyor shell adopts high-quality seamless pipe and valve flange connection, the whole machine has good rigidity and large bearing capacity, and can be continuously conveyed when conveying, whether it is horizontal conveying or large inclination angle, and the working position and working attitude can be selected at will, and it is easy to disassemble and move;

2.It can be loaded and unloaded at multiple points in the middle, and the operation is safe and convenient;

3.The tubular screw conveyor adopts high-quality seamless steel pipes, with good sealing performance, no dust leakage, safety and reliability;

The trough screw conveyor is easy to disassemble, overhaul and maintain;

5.It can realize horizontal conveying and inclined conveying of materials.

Scope of application. The screw conveyor is widely used for horizontal and inclined conveying of powdery and small particle materials such as flour, coal, cement, raw meal, chemical industry, metallurgy, building materials, etc., and the temperature of the conveyed materials is less than 200.

Classification and selection of screw conveyors.

The screw conveyor produced by Chengdu Ruichi Machinery can be customized according to the material, stainless steel screw conveyor, manganese steel screw conveyor and other materials and various types of single-pipe screw conveyor, tubular screw conveyor, single-pipe screw conveyor. It should be noted that the screw conveyor should not convey deteriorated, viscous and easy to agglomerate materials, because these materials will be bonded to the screw when conveying, and rotate without moving forward or form a plug of the material at the hanging bearing, so that the screw machine can not work normally. The screw conveyor is often used with the horizontal screw belt mixer to form a small dry mortar production line.

A bucket conveyor is a bucket conveyor whose hopper rotates on a pin between two chains, and can move horizontally to the discharge point and flip the hopper to discharge the material. Compared with ordinary bucket conveyors, the hopper of the rotary bucket conveyor can rotate on the pin shaft between the two chains, which makes the conveyor better maintain the stability of the material during transportation and reduce the scattering and loss of the material. At the same time, the flipping design of the hopper also makes the unloading more convenient and efficient.

Bucket conveyors are widely used in material transportation in mining, metallurgy, chemical industry, environmental protection, refractory and other industries. Xinxiang Hengyu Machinery Equipment Co., Ltd., the source manufacturer of screening and conveying equipment for 18 years, independently develops and produces: Z-type bucket elevator, square swing screen, U-shaped screw conveyor, tubular screw conveyor, fine screening...

In the process of conveying, if it is used improperly or does not pay attention to maintenance, it is easy to have various failures, and plugging is one of the common ones. Why is there a blockage? How to solve the blockage?

1. The operator does not operate strictly in accordance with the operation specifications, the operator should do no load when starting, the feeding should be uniform, the conveyor will be stopped when there is no load, and the vibration feeder can not be installed in order to ensure uniform feeding. In the feeding process, if the material is suddenly added violently, it is easy to produce blockage, and it will also increase the wear of the conveyor, so it is necessary to gradually increase in the feeding process and slowly reach the rated conveying capacity.

2. If the selected conveyor and the material to be conveyed do not match the effect achieved, it is easy to make the conveyor have the problem of material blockage, so it is necessary to consider carefully when choosing the conveyor, and to select and convey the material to achieve the matching effect.

3. When the screw conveyor conveys the material, there must be impurities in the machine, and if it is not cleaned, it will also lead to the blockage of residual large impurities or fiber impurities, so in order to reduce the occurrence of blockage, the inside of the machine should be cleaned when conveying materials.

4. The bearing of the conveyor is prone to the problem of material blockage, so in order to reduce the occurrence of material blockage failure, the transverse size of the suspension bearing should be reduced as much as possible.

Screw conveyor circuits tend to be relatively small.

The equipment completes an intelligent operation through the complex operation mechanism described, so it is a good small equipment conveyor.

The long-distance screw conveyor is divided from the perspective of the displacement direction of the conveyed material, and the long-distance screw conveyor is divided into two types: horizontal screw conveyor and vertical screw conveyor.

The screw conveyor made of high-strength plastic according to the conveyor chain is also known as the food screw conveyor and screw elevator, which is mainly suitable for conveying large products. Such as cartons, turnover boxes, bottled water, etc.

According to the different characteristics and structure of the conveyed materials, long-distance screw conveyors include horizontal screw conveyors, vertical screw conveyors, bendable screw conveyors, and spiral pipe (roller conveyor) conveyors.
