Top Stacking and Lateral Reclaiming Stacker Reclaimer

Overhead stacker and side reclaimer is a new type of indoor storage equipment developed to meet increasing requirements on environmental protection and land saving. It is mainly used for  handling bulk material, such as coal and ore. This machine is arranged in the enclosed workshop, which can prevent the material and stockpile from the material loss and scattering caused by wind or rain during the stacking process. The surrounding retaining wall make the storage increased in a small space.

Overhead stacker and side reclaimer adopts the technology of cone-shell stacking and side scraper reclaiming, widely used in various raw material yards where the homogenization is undemanding. The equipment is classified into a counterweight type and a gantry type according to the different reclaimer support methods. Various models are supplied with the diameter  from Φ70m to Φ120m, the stacking capacity from 100t/h to 4000t/h, and the retrieving capacity from 250t/h to 3500t/h.

Overhead stacker and side reclaimer is mainly composed of a cantilever slewing stacker, a central pillar, a side scraper reclaimer (portal scraper reclaimer), electric control system and so on. The central pillar is set in the center of the circular stockyard. On its upper part, a cantilever stacker is mounted, which can 360°rotate around the pillar and completes stacking in cone-shell method. 

The side reclaimer(portal scraper reclaimer) also rotates around the central pillar. By the reciprocation of the scraper on the reclaimer boom, the material is scraped off layer by layer to the discharge funnel under the central pillar, then unloaded to the overland belt conveyor for being transported out of the yard. The equipment can achieve continuous stacking and reclaiming operation in full automatic process. Continuously taking and discharging the material ensures the good blending effect.

The circular stockyard with retaining wall can save 40%-50% occupied area than other stockyards with the same storage capacity.

The manufacturing cost of this machine is 20%-40% less than that of other equipment in the same capacity and power.

The circular stacker and reclaimer is arranged in the workshop. Indoor operation prevents the material from wet, wind and sand, thereby keep it stable in composition and moisture, also benefits the following equipment in sufficient output power and smooth running.

Retaining wall is set around the circular stockyard to increase the storage capacity. A hemispherical grid roof on the wall can enclose the dust generated during the operation, thus meeting environmental protection requirements.

The overhead stacker and side reclaimer consist of boom slewing stacking system, side type (portal type) scraper reclaiming system, central pillar, slewing mechanism, lubrication system, console cabinet, etc.
