Crushing and shrinking combined sample preparation unit
Overview of the joint sample preparation unit for crushing:
Crushing and shrinking combined sample preparation unit, also known as commercial coal combined sample preparation unit or two-stage crushing and shrinking prototype. It is a new type of crushing and shrinking integrated equipment developed on the basis of the introduction of advanced technology of foreign sample preparation equipment and in accordance with national standards such as GB474-2008 "Preparation Method of Coal Samples". The overall design of the machine is reasonable, the mechanism is compact, it adapts to large moisture, the sample preparation speed is fast, the fully sealed system, no dust leakage, and there are two kinds of manual and belt conveyor automatic feeding. It is an ideal equipment for upgrading and replacement of laboratory samples. Widely used in the preparation of samples of coal or other granular materials in coal, electric power, metallurgy, and other industries and scientific research units.
Performance characteristics of the combined sample preparation unit for crushing:
1. Fully sealed design, no dust pollution, in line with national standard requirements
2. Uniform feeding, effective anti-blocking, to ensure normal operation
3. The crushing chamber is made of ZG45 precision casting, which is wear-resistant and durable, effectively preventing sample contamination and overheating.
4. Full-width high manganese steel hammer head, fully crushing the material, the working chamber is not blocked, and there is no dead angle phenomenon.
5. High sample preparation efficiency, continuous and rapid completion of feeding, crushing, mixing, and shrinkage, without loss of sample moisture
6. Flexible adjustment of the shrinkage ratio
7. With multiple open windows, it is convenient for daily cleaning, maintenance and repair
8. All transmission components are equipped with protective facilities to meet safety production requirements
9. According to user requirements, optional conveyor belts can be added to transport discarded samples to outdoor or other designated locations.
