CSR series round stockyard stacker/reclaimer

key word:Heat exchange element


Product description

CSR series round stockyard stacker reclaimer

 

1. Introduction

1.1. Purpose

The circular stockyard stacker reclaimer is suitable for all kinds of projects that need to store bulk materials, including power plant coal conveying system, coal mine coal conveying system, material conveying system of metallurgical and chemical industry, port loading and unloading conveying system and material conveying system of iron and steel plant. It is an ideal machine for high-efficiency continuous stacker reclaimer of bulk materials. The circular stockyard stacker reclaimer works in the closed circular storage yard, which makes the materials not affected by the external environment, ensures the normal operation of the conveying system, and does not cause dust overflow due to the wind, reduces dust flying and noise pollution, and is conducive to environmental protection.

1.2. Model meaning

      CSR **/## &&

     CSR -- circular coal yard stacker reclaimer

       **---------Rated production capacity of stacking material (T / h)

       ##---------Rated production capacity of reclaiming (T / h)

       &&----------------------------Yard diameter (m)

1.3. Structural characteristics

The circular stockyard stacker reclaimer includes central column, cantilever stacker and reclaimer. The central column of the equipment is fixed in the center of the coal yard. The cantilever stacker and Reclaimer take the central column as the rotation center, and the feeding trestle belt conveyor is connected with the top of the central column. The cantilever stacker is divided into two structural forms: fixed stacker and pitching stacker. The fixed stacker has the advantages of simple structure, but when there is no material pile at the lower part of the stacker or the material pile is low, the drop is large, and the material dust in the material yard is flying seriously. The pitching stacking adopts the pitching mode of hydraulic oil cylinder. The cantilever can pitch up and down according to the stacking height to reduce the drop of materials and avoid dust flying. At the same time, the height of the central column can be reduced properly, but its structure is relatively complex. The reclaimer is divided into gantry type and cantilever type. One end of the reclaimer is connected with the gantry and the other end is hung on the gantry. The bending shape of the gantry corresponds to the shape of the stock pile. One end of the gantry is connected with the central column and the other end is supported on the circular track on the upper part of the retaining wall. The circular track is set to drive the reclaimer to rotate The structure of the gantry scraper reclaimer is reasonable, which makes the stress state of the central column obviously improved and the operation more stable. The cantilever reclaimer is set on a cantilever frame, which is equipped with a balance weight, and the reclaimer is driven to rotate by the rotation mechanism at the center column. The circular track is not required to be laid on the upper part of the retaining wall. However, the bearing capacity of the central column and the rotating shaft is large.
