The Q69 Series utilizes a roller conveyor system and consists of a pretreatment system, a multi-angle shot blasting unit, a shot blasting circulation system, and a dust removal system. Equipped with multiple high-efficiency shot blasters, the equipment ensures a surface cleanliness level of Sa2.5 and a surface roughness range of 40-70 microns through precisely controlled shot blasting angles and shot flow. Its unique pitless design simplifies installation and significantly reduces construction costs.
The equipment's working width can be customized according to customer needs. Standard models range from 1.5 meters to 4 meters, and its processing capacity extends from 6 mm to 200 mm, meeting the production needs of workpieces of varying specifications. The conveying system utilizes variable frequency speed control, with an adjustable operating speed between 0.5 and 4 meters per minute, ensuring optimal processing results for a wide range of materials.
In practical applications, the Q69 series demonstrates significant advantages. Its centrifugal shot blaster features a dual-disc structure, capable of blasting up to 600 kg per minute, increasing processing efficiency by over 30% compared to conventional equipment. The unique curtain-type shot blaster ensures a sorting efficiency exceeding 99%, ensuring the purity of the circulating shot and significantly reducing equipment wear.
The dust removal system utilizes a pulsed backflush cartridge filter with a filtration accuracy of 0.3 microns. Emission concentrations are strictly controlled below 15 mg/m³, fully complying with national environmental standards. The intelligent control system, equipped with a human-machine interface, can store multiple workpiece processing parameters, enabling one-touch operation and significantly reducing manual operation.
