Quality appraisal of steam powder machine-Machinery & Equipment-CAS Testing Technical Services (Hong Kong) Company Limited

PulverizerAppraisal Background

steam powder machine is a device that uses the energy of high-speed airflow or superheated steam to cause material particles to impact, collide, and frictionally shear with each other to achieve ultra-fine crushing. It is widely used in chemical industry and ultra-fine crushing of non-metallic minerals. The equipment has a simple and ingenious structure, is safe and reliable, easy to use, and low-cost. The particle size of the crushed materials is uniform and the product quality is excellent.
In the case of steam powder machine quality appraisal, Zhongke Testing can provide steam powder machine quality appraisal services.

PulverizerAuthentication case

According to the situation reported by the client and the information provided, the client and the supplier signed a "Purchase and Sales Contract", which mainly stipulates that the supplier shall supply 9 sets of 42" titanium dioxide steam powder machines and related equipment to the client to ensure that the final product particle size is D88 ≤ 0.6 μm, and the production capacity is 4 tons/hour. The steam powder machines involved in the case will be stored in the warehouse after receipt by the client.
The client shall appoint technical personnel assigned by the supplier in accordance with the "Purchase and Sales Contract". The steam powder machine involved in the case was unable to operate normally after two trial runs. During the trial operation, it was found that the steam powder machine had feed back-spraying, serious lining wear, and caused the finished product to be contaminated after material processing, and the impurity content exceeded the standard. The output and quality of the product could not meet the standards agreed by both parties. The supplier of
argued that it produced the steam powder machine involved in the case according to the client's requirements, but the client did not require the design to add dispersant. Imported, and purchased a separate collection system. The failure of the steam powder machine involved in the case was caused by the mismatch between the collection system and the steam powder machine, and there was no quality problem with the steam powder machine itself.
In order to further find out the cause of the accident, the client entrusted our company to conduct a quality analysis on whether there were quality problems with the steam powder machine.
The expert team based on the "steam powder machine involved in the case" provided by the client. Relevant information, on-site investigation and inspection results, and sampling inspection results were discussed and comprehensively technical, and the following quality analysis opinions were made: The steam powder machine involved in the
case had many quality defects such as inappropriate materials and mismatched installation. It was not properly set up to add dispersant imports and was not suitable for the client's existing titanium dioxide processing and production technology requirements, making it impossible to use it normally for titanium dioxide processing and production under the existing conditions.
