Shredder quality appraisal

crusher is a mechanical equipment that can break materials into small particles. It mainly crushes materials through mechanical force. Specifically, the crusher sends the material into the crushing chamber, and uses a high-speed rotating blade wheel or hammer to impact, shear and rub the material to break it into small particles. Depending on the crushing requirements and the nature of the material, different types of crushers can be selected, such as hammer crushers, jaw crushers, etc.
crusher is widely used in the construction industry to crush construction waste, concrete, rocks and other hard materials into reusable materials.
In the case of crusher quality appraisal, Zhongke Testing can provide crusher quality appraisal services.

pulverizers, which are generally divided according to structure. There are two categories: hammer type and claw type: divided according to the feeding method, there are three types of radial, tangential and axial feeding;
divided according to the processed materials, both conventional powder There are crushers for crushing corn and other cereal raw materials, as well as forage crushers that are specialized in crushing various green coarse materials. According to their uses,
has large and medium-sized crushers specifically for professional feed processing companies, as well as small crushers for rural individual users.

was entrusted by a provincial and municipal market supervision and administration bureau to conduct quality appraisal of 10 batches of feed grinder products. In accordance with the requirements stipulated in national standards and related product standards, the appraisal expert group inspected 15 items including the safety requirements of the feed grinder product, rotor balance, productivity, power consumption per ton of material, noise, bearing temperature rise, poor hammer (flat tooth) quality, hammer (flat tooth) hardness, appearance quality, coating thickness, coating adhesion, safety signs, safety precautions in the instruction manual, product labels, and direction of rotation signs.
identification analysis results: The
identification expert group discussed and comprehensively analyzed the relevant information, on-site investigation and inspection results of the "feed grinder" involved in the case, and made the following identification opinions:
1, individual product hammer (flat tooth) hardness items failed.
2, individual product coating thickness and coating adhesion items failed.
3, the bearing temperature rise item of some products failed.
