The salt plant production environment places high demands on equipment reliability. The more complex the equipment structure, the more potential failure points, and the greater the difficulty and cost of maintenance. Gaofu's GLS series salt probability screen pursues simplicity and practicality in structural design:
Dual vibrating motor drive for a streamlined structure. The probability screen is driven by two vibrating motors or exciters of the same model and specification operating in synchronised opposite directions. Compared with the complex transmission systems of conventional screens, the dual‑motor drive structure is simpler, reducing wear and failure risks of mechanical transmission components. The excitation motors cause the screen surface to vibrate at high frequency without the need for additional transmission devices.
Multi‑deck screens arranged vertically for high space utilisation. The equipment consists of a frame and a set of multiple overlapping screen decks, with slope increasing from top to bottom and mesh size decreasing from top to bottom. Multiple screen decks are arranged vertically within the limited equipment space, achieving multi‑stage grading functionality. This layout saves floor space and simplifies material flow paths between decks.
Fully enclosed structure reduces external interference. The equipment features a fully enclosed design – no dust emission, smooth operation. The fully enclosed structure not only improves the workshop environment but, more importantly, reduces external dust erosion of internal equipment structures and lowers the risk of dust entering bearings and other precision components.
Quick‑release inspection cover for convenient maintenance. The equipment is equipped with an inspection cover with quick‑release pins, allowing operators to easily and quickly open the cover to inspect screen condition. This design makes routine inspection and maintenance more efficient, reducing downtime.
Wide screening mesh range – one machine, multiple uses. The screening mesh covers 5 mm down to 0.075 mm (200 mesh) – a single machine can meet multiple screening requirements from coarse salt to ultra‑fine salt powder, reducing equipment adjustment work when switching between different specifications.
Integrated transport and installation for simple commissioning. The equipment is transported and installed as an integrated unit – only amplitude adjustment is required on site according to site conditions. The simple installation and commissioning process enables rapid production start‑up.
Screening efficiency is the core indicator of screening equipment performance. Gaofu's GLS series salt probability screen achieves high screening efficiency through its unique working principle and multiple targeted design features:
Probability screening principle for rapid screening. The probability screen is a screening machine that actively utilises the probability screening principle. Probability screening theory states that particles much finer than the mesh openings pass through the screen surface quickly, while particles close to the mesh size have extended residence time. The probability screen actively leverages this principle, reducing screening time to only 1/3 to 1/20 of that of conventional vibrating screens. Screening performed on a probability screen is "rapid screening."
High‑inclination screen surface – material does not accumulate. Screen inclination increases from top to bottom – material gains high velocity at the feed end, the material bed rapidly thins, and material moves forward quickly. Material "slides down" like a slide without accumulating or blocking on the screen surface – screening efficiency is ensured.
Large‑aperture screen mesh – mesh openings do not block. The screen aperture is designed at 1.2 to 2.2 times the target separation particle size. Material disperses quickly upon entering the screen, eliminating screen blinding caused by near‑mesh particles. The screen does not block, does not deform, and material does not cross layers. While maintaining the screening accuracy of conventional screens, throughput can be increased by 2 to 4 times.
Uniform feed distribution – high screen utilisation. Feed distribution is uniform – material is evenly distributed on the screen surface, and all areas of the screen are utilised equally, avoiding efficiency losses from local overloading or local idle areas.
Screening efficiency ≥95%. Gaofu's GLS series probability screen achieves screening efficiency of over 95%. High screening efficiency means less rework and higher product qualification rates.
The continuous production of salt plants places high demands on equipment operational stability. Gaofu's GLS series salt probability screen ensures continuous operation capability across multiple dimensions:
Long screen life reduces screen change downtime. The screen surface is arched, and the external ratchet tensioning device allows operators to easily control screen tension, keeping the screen flat and secure. Under normal operating conditions, continuous screen service life can be maintained for over 60 days. Longer screen life means fewer screen changes and higher equipment utilisation. Screen replacement is quick and convenient, completed within a short time.
Fully enclosed structure reduces dust erosion of equipment. The fully enclosed, dust‑free design effectively reduces salt dust erosion of external equipment structures and internal precision components. Salt dust entering bearings and other components is a common cause of equipment failure – the fully enclosed structure reduces this risk at the source.
Smooth operation with low noise. The equipment runs smoothly with low noise. Smooth operation reduces mechanical fatigue and extends the equipment's overall service life.
Single machine can grade multiple fractions, reducing equipment count. A single machine can simultaneously grade 2 to 7 particle size fractions. One machine completes multi‑stage grading, reducing the number of machines and connection points between them, thereby lowering the risk of failure and maintenance workload associated with multiple machines in series.
Wide application range – strong material adaptability. The probability screen has a wide application range and is available in standard and corrosion‑resistant versions. Applicable materials include granulated white sugar, raw salt, and edible salt. Whether for sea salt, lake salt, rock salt, or refined salt, suitable screen configurations are available. Strong material adaptability enables stable operation across different salt types and operating conditions.
Gaofu's GLS series salt probability screen delivers practical value in continuous salt plant production in the following ways:
Reduced unplanned downtime. Simple structure means fewer failure points; long screen life means lower screen change frequency; fully enclosed structure means less dust erosion – combined, these significantly reduce the probability of unplanned downtime. For salt plants operating 24/7, every unplanned downtime means production loss and order delays.
Reduced maintenance workload. The simple structural design and convenient access for inspection make routine maintenance more efficient. Operators can focus more on production monitoring rather than equipment repair.
Improved equipment utilisation. Less downtime and longer continuous operating cycles mean higher equipment utilisation. In the same amount of time, a single probability screen can complete more work, reducing equipment idle and waiting time.
Production rhythm is maintained. Screening equipment no longer constrains the efficiency of the entire production line – upstream crystallisation and drying output is processed in time, and downstream packaging gets a stable material supply – the entire production line runs more smoothly and predictably.
