The LS-type screw conveyor features the following characteristics:
- Simple structure with relatively low manufacturing costs.
- High operational reliability and straightforward maintenance management.
- Compact dimensions with small cross-section, minimizing floor space. Facilitates access to ship hatches and truck compartments during port unloading operations.
- Sealed conveying capability ideal for transporting dusty, hot, or strong-odored materials, reducing environmental pollution and improving working conditions for port personnel.
- Flexible loading/unloading: Horizontal screw conveyors allow material intake/discharge at any point along the path. Vertical screw conveyors paired with spiral reclaimers achieve superior material retrieval.
- Bidirectional functionality: Capable of reverse operation or simultaneous material conveyance in two directions (toward or away from the center).
- Higher energy consumption per unit load compared to some alternatives.
- Material degradation and wear: Fragile materials may undergo grinding during transport. Screw blades and troughs experience relatively severe wear.

FAQ
What are the main products of our company?
Zhengzhou Miqi Machinery Equipment Co., Ltd. has a professional R&D team dedicated to the research and innovation of egg tray machines, egg tray production lines, pulp molding production lines, industrial packaging, tableware packaging, and automatic packaging machines. With years of theoretical and practical experience, we provide customers with comprehensive after-sales service.
Packaging system
The dried egg trays are sent through an automatic collection machine, counted, then compressed by a packaging machine, and finally packaged onto trays. This results in space savings and improved transportation convenience.
Metal drying system
The drying cabinet is linked to the molding machine. The wet trays are transferred to the drying cabinet for drying. The insulation layer is made of high-density mineral insulation cotton. The drying room has six layers, and the drying time is approximately 17-18 minutes. The uniquely designed circulating fan and automatic dehumidification system drive the hot air to circulate, removing moisture and drying the trays. This not only improves the drying efficiency but also reduces labor costs.
Brick kiln drying
The brick drying kiln has only one layer and is 60-80 meters long. The length may vary depending on the production volume. The formed egg trays are conveyed into the kiln through a mesh belt. The temperature should be controlled between 180-220 degrees. After about 20 minutes, the egg trays come out dry.
