sawdust screw conveyor

Product introduction of sawdust screw conveyor

Sawdust screw conveyor is used to move sawdust or wood chips or other similar material from one location to another, or to transport wood chips to storage bins or other destinations. , which consists of a rotating screw or auger that moves sawdust along a slot.

The design of the Sawdust screw conveyor may vary depending on the specific application and the characteristics of the material being conveyed. Factors such as screw diameter, pitch and speed, as well as trough shape and size all affect conveyor performance. It is important to select the correct components and design parameters to ensure efficient and reliable operation.

Application

Sawdust screw conveyors are commonly used in a variety of industries and applications, including:

Woodworking: Typically used in woodworking facilities to transport sawdust and other wood waste from one part of the facility to another.

Pulp and Paper: Can be used in pulp and paper mills to convey wood chips, sawdust and other wood waste.

Biomass Energy Production: Typically used in biomass energy production facilities to convey sawdust and other wood waste to biomass boilers or other processing equipment.

Agriculture: Can be used in agricultural applications to transport animal feed, grain and other materials.

Advantage

1. The propelling helical blade can push the sawdust forward, solving the problem of poor fluidity and difficult transportation of sawdust;

2. Multiple inlets and outlets can be designed to feed wood chips at multiple points to meet the production layout in the actual scene;

3. There is no dead angle or obstruction in the sawdust conveying pipe groove, which can ensure the smooth conveying of sawdust, and the conveying capacity can reach 458 cubic meters per hour;

4. It can be designed to be completely sealed to ensure that the sawdust dust does not leak or fly during the transportation process, and avoid pollution.

product structure

The sawdust screw conveyor is mainly composed of a driving device, a casing, a cover plate, a screw shaft, a screw blade, a material inlet, and a material outlet.

1. Driving device: Composed of motor and deceleration device, it drives the screw shaft and the screw blades to rotate.

2. Spiral blade: used to push wood chips forward to the specified conveying direction.

3. Chassis: It provides operating space for sawdust conveying, which can be divided into "U"-shaped casing and circular casing. The circular casing is mainly used for sealing equipment feeding. It is good to convey materials horizontally (the casing can be sealed or not).

4. Spiral shaft: It is made of hollow steel pipe, and a small section of solid shaft is used at the connection between the shaft and the shaft and where the bearing is installed. The solid shaft has a small diameter and can be plugged into the hollow steel pipe for connection without any connection protrusions causing material blockage.

Solutions by Industry

Here are three different customer cases of sawdust delivered by screw conveyor:

• 

  Carpentry Facilities

  Woodworking facilities that produce furniture and other wood products produce large amounts of sawdust as a by-product. The sawdust is collected and transported via a sawdust auger to a storage silo for later use as fuel for the facility's biomass boilers. Sawdust screw conveyors are designed to handle large volumes of sawdust and run continuously to keep up with production rates.

• 

  Pulp and Paper Mills

  Pulp and paper mills use sawdust augers to transport wood chips and sawdust from the log yard to the pulp digester. Screw conveyors are designed to handle large volumes of wood chips and run continuously to keep up with the plant's production rate. Sawdust and wood chips are used as a fuel source for the mill's recovery boiler, which generates steam for the papermaking process.

• 

  Biomass Energy Production Facility

  Biomass energy production facilities use sawdust screw conveyors to transport sawdust from storage silos to biomass boilers for combustion. The screw conveyor is designed to process a specific amount of sawdust per hour and runs continuously to maintain a steady supply of fuel to the boiler. Biomass boilers produce steam that is used to generate electricity and sold to the grid. The sawdust auger conveyor is a key component in the operation of the facility as it ensures a reliable and efficient supply of fuel to the boilers.
