Best bucket wheel stacker reclaimer details of types

What is a bucket wheel stacker reclaimer?

Bucket wheel stacker and reclaimer refers to a high-efficiency loading and unloading machine used for continuous conveying of both stacking and reclaiming materials in large dry bulk storage yards. It is composed of a belt conveyor arm that can tilt and swing horizontally and its front bucket wheel, frame, and running mechanism. The belt can run in both directions. When reclaiming materials, the bucket wheel reclaims the material and sends it out through the conveying arm, and when stacking, the main conveyor The delivered goods are thrown to the yard via the conveying arm.

Bucket wheel stacker classification

Bucket wheel stacker and reclaimer can be divided into two types: boom type and bridge type. Some equipment has only one function of reclaiming material, which is called bucket wheel reclaimer.

1. Boom type

The boom type bucket wheel stacker and reclaimer is composed of a bucket wheel mechanism, a slewing mechanism, a belt conveyor, a tail car, a pitching and running mechanism. It has two operation modes: stacking and reclaiming. The bulk material transported by the belt conveyor is unloaded to the belt conveyor on the boom by the tail truck, and is dumped from the front end of the boom to the material yard. Through the operation of the whole machine, the rotation and pitch of the boom can make the material pile form a neat shape of trapezoidal section. Reclaiming is realized continuously through the rotation of the boom and the rotation of the bucket wheel. The material is unloaded to the reverse-running boom belt conveyor through the unloading plate, and then unloaded to the material yard belt conveyor through the hopper below the center of the machine to be transported away. Through the operation of the whole machine, the rotation and pitch of the boom can make the bucket wheel take out the material in the storage pile.

2. Bridge type

The bridge type bucket wheel stacker and reclaimer is divided into two types: portal type and bridge type according to the bridge type.

Portal bucket wheel stacker and reclaimer: It has a portal-shaped metal frame and a liftable bridge. There is a fixed and a movable stacking belt conveyor on the gantry beam, which can run in both directions, and a tail car running with the gantry is arranged on the belt conveyor line of the material yard on one side of the gantry. The plain bucket wheel is set on the trolley that can run along the lifting bridge through the circular raceway, the supporting wheel and the blocking wheel, and a belt conveyor is installed in the bridge. When stacking, the materials are transferred to the stacking belt conveyor through the material yard belt conveyor and tail car, and finally dumped to the material yard. 

Through the movement of the gantry and the operation of the upper stacking belt conveyor, the materials are formed into a certain shape of the stack. When reclaiming material, the material is continuously reclaimed by the horizontally running trolley and the bucket wheel rotating on it. The material is unloaded to the bridge belt conveyor in the unloading area, and finally transferred to the material yard belt conveyor to be transported away. Through the lifting and lowering of the bridge and the operation of the gantry, the material can be taken out.

Bridge bucket wheel reclaimer: The main difference in structure with the portal bucket wheel stacker reclaimer is: it does not have a tall gantry, the bridge is fixed and does not lift, and is in a lower position; there is no stacking belt type Conveyor and tail car; There is a rake fixed on the trolley in front of the bucket wheel. When the trolley is running, the rake is driven to move along the end face of the material pile, so that the bulk material above slides down, so that the bucket wheel can take the material. The rake can also make the materials stacked by the stacker in layers according to different materials to be mixed evenly when they slide down, so it is often called a bridge-type bucket wheel mixing and reclaiming machine.
