Coke sampling system

Product Details


◎ System planning is based on GB/T2005 GB/T2006.GB1997. It is divided into three parts: sieve size analysis, mechanical strength analysis and component sample preparation. The preparation of component samples is independent and parallel with the other two parts. See "Coke System Process Flow Chart". After the system is started, the head sampler obtains a certain amount of sample from the main belt blanking stream according to the set sampling period and feeds it into the primary belt feeder. After the belt machine shapes the flow, it is slowly and evenly transported forward. At this point, depending on the need to switch the direction of the tee, the sample can be entered into three different processes.

Screening particle size analysis:

◎The sample is evenly fed to the five-stage vibrating screen through the primary belt feeder and tee, and the sample is divided into five grades of ≤25mm, 25-40mm, 40-60mm, 60-80mm>80mm and sent to the corresponding Weighing scales weighed their respective weights to obtain the fractional composition and calculate the end of coke content of ≤25 mm.

Mechanical strength analysis:

◎The system takes the drum test sample according to the specification. After the particle size screening is completed, the control system starts the reversible belt conveyor and the drum bucket scale. According to the specification, the coke block larger than 25 mm is fed into the drum with a proportion of 50 kg. The drum was subjected to mechanical strength test, and then the sample after the experiment was poured into a mechanical three-stage circular sieve, and the coke particle size of >25 mm, 25-10 mm, ≤10 mm was sieved and weighed separately, thereby calculating the crush resistance of the coke. Strength (M25)% and abrasion resistance (M10)%.

Preparation of component samples:

◎The sample is fed to the primary belt feeder, and the tee tube is evenly fed to the hammer type to break below 6 mm. Then, the effect of the reducer is used to reduce the amount of sample (2-5kg) stored in the collection tank for experimental analysis. Excess samples fall into the reject conveyor, and all samples after the end of the experiment fall into the reject conveyor and are transported to the designated location.
