Mine vibrating screen quality appraisal

mining vibrating screen is mostly used in metallurgy, mining, coal, building materials, electric power, chemical industry and other industries. It is a high-efficiency screening equipment.
mining vibrating screen is mainly composed of screen box, screening machine, vibrator, damping spring device, chassis, suspension (or support) device and motor. It has the characteristics of shape vibration, multi-layer high efficiency, long service life and wide application range.
In the case of mining vibrating screen quality appraisal, Zhongke Testing can provide mining vibrating screen quality appraisal services.

can be divided into heavy-duty mining vibrating screens, lightweight precision vibrating screens and laboratory vibrating screens according to the different weight classes used.
heavy-duty mining vibrating screen can be divided into: high-efficiency heavy-duty vibrating screen, self-centering vibrating screen, elliptical vibrating screen, dewatering screen, circular vibrating screen, banana screen, linear vibrating screen, etc.
lightweight precision vibrating screen can be divided into: rotating screen, linear screen, straight screen, ultrasonic vibrating screen, filter screen, etc.
laboratory vibrating screens include: slap vibrating screen, top impact vibrating screen, etc.

was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the mining vibrating screen involved.
appraisal analysis results:
appraisal analysis expert group discussed the relevant information and on-site investigation of the mining vibrating screen involved and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The mining vibrating screen involved in the case has a large height difference between the rubber springs on the left and right sides, and there is no protective cover at the rotation position of the motor coupling, which does not meet the requirements of relevant standards.
