Conveyor Reasons for consideration

1. Environmental conditions
Most of the warehouses operate with air conditioning and lighting. In cases of extreme temperatures, belts, bearings and drive units need to be specially selected. Although the warehouse is in a relatively clean environment, the conveyor system may have to connect a cleaner area to a harsher environment (e.g., waste carton area). Some items must be segregated for health and safety reasons, and these factors can also affect the design of conveyor systems and storage areas.

2. Consideration of the selection of conveying products
Because the surface of the conveyed goods is in direct contact with the conveyor, the characteristics of the goods directly affect the selection of the equipment and the design of the system. The characteristics of the conveyed goods include size, weight, surface characteristics (soft or hard), processing rate, packaging method and center of gravity, etc., which are all factors to be considered.
When planning, all items to be conveyed should be listed, the smallest and the largest, the heaviest and the lightest, sealed and unsealed. Not only the largest or heaviest items will influence the design of the equipment.
For example, lighter items may not allow the sensor to operate, and smaller items may affect the choice of equipment type, such as roller or belt. For some cumulative conveyors, the range of item weight distribution has a significant impact. When planning, the main system does not need to handle all items, and it may be more economical to have a second system or to manually handle the less frequently used items.

Screw Conveyor.

Screw conveyor is a kind of machinery that uses motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyor is divided into two kinds of conveying form: shafted screw conveyor and shaftless screw conveyor, and in appearance, it is divided into U-type screw conveyor and tubular screw conveyor.

Screw conveyor Working Principle

With multi-directional movement, materials without centrifugal force, no specific gravity deviation and stratification, accumulation phenomenon each group can have a disparity in weight ratio, mixing rate of 99% or more, mixing uniformity is higher than the uniformity of other ordinary mixers

The barrel loading rate is large, up to 80-90% (only 40% for the ordinary mixer), high efficiency, short mixing time. The cylinder body is rounded and polished in all parts.

Screw conveyor Features

The 3D swing mixer is composed of the machine base, drive system, three-dimensional movement mechanism, mixing cylinder and electrical control system, etc.

The mixing barrel in direct contact with the material is made of high-quality stainless steel, the inner wall of the barrel is polished and processed with precision.

Screw conveyor Applications

Screw conveyor is mainly used for conveying various powder, granular and small lump materials. The bulk materials conveyed are grain, beans, flour and other grain products, construction materials such as cement, clay and sand, chemicals such as salt, alkali and fertilizer, and bulk bulk goods such as coal, coke and ore. Screw conveyor is not suitable for conveying perishable, sticky, lumpy and lumpy materials. In addition to conveying bulk materials, screw conveyors can also be used to transport a variety of items. Screw conveyor can be used for mixing, stirring, cooling and other operations while conveying materials.

Screw conveyor Composition

The screw conveyor consists of three parts: the body of the screw machine, the inlet and outlet and the driving device.

The screw body consists of head bearing, tail bearing, suspension bearing, spiral, housing, cover and base.

The driving device is composed of motor, reducer, coupling and base.

Bucket Conveyor.

The bucket elevator is a continuous conveying machine that uses a series of hoppers evenly fastened to endless traction members to lift materials vertically. The bucket elevator uses a series of hoppers fastened to traction chains or tapes to transport bulk materials upward in the vertical or near-vertical direction.

Bucket Conveyor Working Principle

The hopper lifts the material from the storage below with the conveyor belt or chain to the top, turns downward after bypassing the top wheel, and the bucket elevator dumps the material into the receiving trough.

The drive belt of the belt-driven bucket elevator generally uses rubber belt, which is mounted on the lower or upper drive drum and the upper and lower redirecting drum.

Chain-driven bucket elevators are generally equipped with two parallel drive chains, with a pair of drive sprockets on the top or bottom and a pair of redirecting sprockets on the bottom or top. The bucket elevator is equipped with a housing on the outside to prevent dust from flying in the bucket elevator.

Bucket Conveyor Composition

The bucket elevator consists of a hopper, drive unit, top and bottom drums (or sprockets), traction chain, tensioning device and body.

Rubber belt: fastened to the mouth of the belt with screws and elastic gaskets, the belt is 35 to 40mm wider than the bucket, the general tape conveys materials with a temperature of no more than 60°C, and the heat-resistant tape can convey materials up to 150°C.

Chain: single chain is fastened to the back wall of the hopper; double chain is connected to both sides of the hopper.

Chain wheel: The transmission sprocket on the bucket elevator. The chain wheel is used to engage with the accurate pitch block on the chain ring or cable, and is a solid or spoked gear that engages with the roller chain to transmit movement.

Bucket Conveyor Features

Small driving power, inflow feeding, induced discharge, large capacity hopper intensive arrangement.

Wide lifting range, this type of elevator requires less material types and characteristics, not only can lift the general powder, small granular materials, and can lift the abrasive materials, good sealing, less environmental pollution.

Good operation reliability, trouble-free time more than 30,000 hours. Lifting operation is smooth and can reach high lifting height.

Long using life, the feeding of the elevator takes inflow type, no need to dig material with bucket, little extrusion and collision between materials, reducing mechanical worn out.

Bucket Conveyor Maintenance Notes

All products in the hopper should be emptied before stopping each time.

The lifting direction should not be reversed, because the chain may be derailed.

Feed the material evenly. Prohibit sudden increase of feeding volume. Feeding volume can not exceed the conveying capacity of the hoist. Otherwise, it is easy to cause serious accumulation of materials at the bottom.

Replenish lubricating oil timely and appropriately.

The chain and hopper should be replaced in time when they are seriously worn or damaged.

Belt Conveyor.

Belt conveyor, also known as tape conveyor, is widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc., assembly, testing, debugging, packaging and transportation of objects.

Belt Conveyor Profile

Belt conveyor is a friction-driven machine that transports materials in a continuous manner.

It is mainly composed of frame, conveyor belt, rollers, tensioning device and transmission device.

It can form a material conveying process from the initial supply point to the final discharge point on a certain conveying line. It can convey both scattered materials and finished goods. In addition to pure material conveying, it can also cooperate with the requirements of the process in the production process of each industrial enterprise to form a rhythmic flow operation transportation line.

Belt conveyor Working Principle

A belt conveyor consists mainly of two endpoint rollers and a closed conveyor belt that is tightly set on them. The pulley that drives the belt is called the drive pulley (transmission pulley); the other pulley, which is solely concerned with changing the direction of the belt movement, is called the redirection pulley.

The drive pulley is driven by an electric motor through a reducer, and the conveyor belt is dragged by the friction between the drive pulley and the conveyor belt. The driving drum is generally installed at the discharge end to increase the traction force and facilitate dragging. The material is fed from the feed end, falls on the rotating conveyor belt, and is transported to the discharge end by the friction of the conveyor belt.

Belt Conveyor Features

Belt conveyor has the advantages of long conveying distance, large capacity, continuous conveying, etc. It is also reliable and easy to realize automation and centralized control.

The machine body is flexible, the frame is light, and it is very convenient to disassemble. When the conveying capacity and distance are large, it can be equipped with intermediate driving device to meet the requirements. According to the requirements of conveying process, it can be conveyed by a single machine, and also can be combined into a horizontal or inclined transport system by multiple units to convey materials.

Large conveying capacity, simple structure, easy maintenance, low cost and strong versatility.
