A gypsum block production line mainly consists of a batching system, a mixing system, a molding machine, a central hydraulic station, a drying system, and automatic palletizing equipment.
The batching system is responsible for accurately metering raw materials such as water and powders (e.g., gypsum powder, fly ash). It includes a water metering device (effective volume 450L, adjustable range 200-450L), a powder metering hopper (maximum weighing capacity 500kg, high metering accuracy), and a compressed air system (used for purging, spraying release agent, etc.).
The mixing system uses a dual high-speed paddle mixer with a maximum tank volume of 800L. It is equipped with an automatic lid opening and hydraulic discharge mechanism to ensure uniform mixing of the slurry.
The molding machine is designed based on the vertical mold lifting principle and includes a mold box, pressure head, hydraulic scraper, and bottom mold sealing device. The mold typically has 16 cavities, capable of producing 500×600×80mm blocks, with a maximum ejection force of 1350KN. The mold surface is hard chrome plated and mirror-polished to ensure high precision and long service life.
The central hydraulic station provides high and low pressure power (300bar high pressure, 150bar low pressure) to drive the molding and demolding processes. It features automatic high/low pressure switching to prevent slurry blockage.
The drying and post-processing system integrates vacuum dehydration and automatic drying devices in some advanced production lines, improving drying efficiency and finished product strength. It is also equipped with an automatic palletizing system to reduce manual intervention and enhance automation.
