Product Description
The scraper reclaimer is a core device used in the production of clay fired bricks for efficiently reclaiming materials from raw material stockpiles (such as clay, shale, etc.). Its main structure includes the scraper device, traveling mechanism, frame, drive system, and control system. The working principle is as follows: the traveling mechanism moves the entire machine along the longitudinal direction of the raw material pile. Meanwhile, the scraper device scrapes off the raw materials from the surface of the pile layer by layer, which then fall into the belt conveyor or chain plate conveyor below, achieving continuous material reclaiming and conveying. Mainstream equipment in Europe and America usually features automated control functions, which can precisely adjust the reclaiming speed and the thickness of the reclaiming layer to meet the needs of large-scale industrial production.
Advantages of the Equipment:
1. Efficient Continuous Operation: The scraper reclaimer can operate 24 hours a day without interruption. When combined with an automated control system, it significantly enhances the efficiency of raw material handling.
2. High Uniformity of Reclaiming: By scraping materials layer by layer, the scraper ensures a uniform distribution of particle size and moisture content in the reclaimed materials. This reduces the differences caused by material stratification.
3. Adaptability to Various Stockpile Types: It is suitable for different shapes of raw material stockpiles, such as elongated piles and circular piles. It is especially effective for materials with high moisture content or stickiness.
4. Low-Wear Design: The scraper is made of wear-resistant alloy materials (such as manganese steel). Combined with an adjustable scraper angle, this design reduces friction and wear when in contact with the materials, thereby extending the service life of the scraper.
5. Intelligent Control: The equipment is integrated with a PLC control system, which allows remote monitoring of parameters such as reclaiming quantity and traveling speed. This reduces the need for manual intervention and lowers operational costs.
Functions of the Equipment:
1. Raw Material Homogenization: By scraping materials from different positions layer by layer, the scraper reclaimer achieves "horizontal cutting and vertical mixing" of the raw material pile. This eliminates regional differences in the composition of the raw materials, providing a uniformly mixed material for subsequent processes such as mixing and forming.
2. Flexible Feeding: The equipment can dynamically adjust the reclaiming speed according to the requirements of the upstream production line (such as the processing capacity of mixers and crushers). This prevents insufficient or excessive material supply, thereby balancing the production process.
3. Large Stockyard Management: In open or enclosed stockyards, the scraper reclaimer efficiently manages a large amount of raw materials. It reduces the costs associated with manual stacking and reclaiming of materials and improves the utilization rate of storage space.

Comparison between Scraper Reclaimer and Semi-Gantry Scraper Reclaimer:
| Comparison Dimension |
Scraper Reclaimer |
Semi-Gantry Scraper Reclaimer |
| Structural Feature |
The whole machine moves longitudinally on rails via traveling wheels, with a compact structure suitable for small to medium-sized stockyards. |
Adopts a semi-gantry frame (one-side support leg + rails on the other side), with a larger span, suitable for large stockyards. |
| Reclaiming Range |
Covers the longitudinal direction of the stockpile, requiring a stacker for layered stacking; limited reclaiming width. |
The scraper device can move transversely to cover the full width of the stockpile, supporting "fixed-point reclaiming" or "full-width scraping". |
| Automation Level |
Usually equipped with basic automatic control, suitable for standardized processes. |
Integrated with more complex positioning systems and sensors, supporting precise reclaiming in three-dimensional space. |
| Application Scenario |
Small to medium-sized clay brick factories with small or regularly shaped raw material piles. |
Large industrial brick factories or raw material storage centers handling high-density and large-volume stockpiles. |
| Investment Cost |
Lower cost, suitable for small to medium-sized enterprises with limited budgets. |
Higher cost, requiring a semi-gantry frame and rail system, suitable for large-scale production needs. |
The Importance of the Equipment in the Process Flow:
1. Core Link in Raw Material Preprocessing: As the "first process" in the clay fired brick production line, the uniformity of its material reclaiming directly affects the stability of subsequent mixing, forming, and firing processes. It is the foundation for ensuring the quality of the bricks.
2. Key Factor in Production Efficiency: The high-efficiency material reclaiming capability can prevent production line shutdowns caused by insufficient raw material supply. Especially in continuous production mode, the reliability of the equipment directly determines the upper limit of production capacity.
3. Core Equipment for Cost Control: Through automated homogenization and material reclaiming, it reduces human intervention and raw material waste (such as dust loss caused by "scraping material"), thereby reducing the overall production cost.
