No matter what kind of sampling head (auger type, claw type, cylinder type) or sampling method (full section, non-whole section) is adopted, according to the practice, wagon/train mechanical automatic sampler can realize barrier-free sample collection. But because of the limits of the crushing system, traditional sampler has the common problem of “can finish sampling but can’t finish sample preparation”. By using Sundy original umbrella spinTM technology, all-pass sampling system completely solves the problems of “blockage” and “stuck” in the process of sampling, and the system itself is not restricted by moisture and is all-pass operation.
All-pass sampling system includes train bridge/portal sampling system, belt sampling system (Cross belt/ Falling stream), so its design, manufacturing and performance is in line with standards. Based on jobsite situation and different customized needs, Sundy can provide “one-to-one” professional products consulting and re-design service to meet the customer needs to the maximum extent.
SDSS All-pass sampling system can be widely used for sampling of coal, coke and similar material transported by belt in the field of Power plant,Steel plant, Cement plant, Coal Mining, Metallurgy, Chemical, Coking, Building material, port, grain,etc.
It can be customized as per customer’s requirement. etc.
Sampling device is the key part of truck sampler. Reasonable design for sampling device can affect the performance of whole sampler. Sundy provides auger type sampling head. It is worth to mention that cylinder type sampling head is specially designed by Sundy with patent.
1. Common sampling head, single point full-section sampling can be realized.
2. Auger with crushing function, big particle size sample can be crushed.
3. With primary dividing function.
2.Wet coal crusher with “ Umbrella Spins” TM
At present, all the sampler system with sample preparation equipment in the market can only work under some conditions like coal type and certain moisture level so that they can ’t resolve the problem of adhesion of wet coal. Stuck and blockage appears and the system is not stable. Sometimes the whole system will stop working to rely on manual handling. Then management risk by manual handling can’t be avoided.
SDSS all-pass sampling system could automatically sense and judge the material crushing and processing situation in the crushing cavity, and based on this, control the feeding speed by frequency conversion to realize the linkage and matching with crushing capacity. At the same time, the system adopted the hammer crushing structure with strong crushing capability and equipped the unique separate-slot type crushing sieve screen and hammer head, the efficiency of crushing and discharging is improved and “stuck” due to overfeeding beyond crusher ability is avoided, to minimize the sample residue.
