The fully automatic salt harvester is specifically designed for sea salt fields, salt lakes, and industrial crystallized salt production sites. It integrates salt block crushing, raw salt collection, brine suction, hoisting and conveying, and automatic loading into a single system. The equipment uses low-pressure rubber tracks for mobility, effectively protecting the bottom of salt pans and adapting to tidal flats, muddy terrain, and complex salt field environments.
With a harvesting capacity of 150–400 metric tons per hour and powered by a 55-kW diesel engine, it allows a single operator to perform continuous harvesting operations. To meet the diverse needs of salt production facilities, we offer models without a crushing function, models with a crushing function, small-scale custom models, and standard tracked models. These solutions help salt companies reduce labor costs, improve raw salt recovery rates, and achieve automated upgrades in salt field harvesting operations.
Salt harvester Design Highlights and Key Advantages
- Cost & Efficiency Optimization: Replace manual harvesting, solve labor shortage and low efficiency, support continuous production and boost profits.
- Wide Working Adaptability: Optional front crusher for hardened salt; standard model fits loose salt layers, meeting diverse salt field demands.
- Salt Pond Protection: Widened rubber crawler with low ground pressure protects pond bottoms, adapts to complex terrains and reduces maintenance costs.
- Stable Powerful Performance: 55kW high-torque diesel engine runs steadily under heavy load, thick salt layers and high-salinity environments.
- High Salt Recovery Rate: Dual-pump suction and high-pressure flushing clean residual salt thoroughly, avoid blockage and reduce downtime.
- Integrated Automatic Operation: Integrates crushing, harvesting and conveying, compatible with assembly lines for large-scale automatic production.
- High Equipment Utilization: Detachable reducer supports other equipment power output, realizing multi-function use and saving investment.
Industries Suitable for the Salt Reclaimers
Our salt harvester supports mechanized harvesting of sea salt, lake salt, solar salt, and industrial crystalline salt. It fits salt fields of all scales and can be matched with salt transport vehicles and salt pond compactors to form an integrated production system. Widely used in global salt industry projects and exported to Asia, Africa, the Middle East, South America, and other regions.
Main Application Scenarios:
- Coastal Sea Salt Fields: Suitable for large-scale harvesting in coastal sea salt crystallization ponds and greatly improves working efficiency in peak seasons.
- Inland Salt Lake Plants: Ideal for mechanized mining and processing of natural lake salt resources.
- Industrial Salt Factories: Realizes automatic raw salt harvesting for salt mine crystallization ponds and refined salt production lines.
- Large-scale Salt Projects: Supports full-process mechanization including salt harvesting, transportation and pond maintenance, applicable for commercial salt projects at home and abroad.
How does an industrial salt harvester work?
The automatic salt harvester realizes continuous mechanized operation including salt crushing, collecting, brine suction and automatic loading, with two working modes: crushing type and non-crushing type.
Complete Working Process:
- Salt Preprocessing: The crushing model breaks hardened and caked salt into loose fine salt; the non-crushing model directly collects loose crystalline salt to adapt to different salt field conditions.
- Salt and Brine Collection: The spiral hopper gathers salt-brine mixture. Dual pumps work together for fast suction and transmission, while high-pressure water flushes residual salt at the bottom to improve recovery rate.
- Lifting and Automatic Loading: The vertical conveyor transports salt materials to the top discharge port for automatic stacking or direct loading onto salt transport vehicles, realizing continuous unmanned harvesting.
The whole salt harvester machine runs automatically and stably. On-site operation videos of crushing, traveling, and loading are available.
