Product Overview
The Manufactured Sand Production Line is specialized sand preparation equipment developed from premium sand-making tower technology. It focuses on producing manufactured sand within the 0~3 mm particle-size range.
The line adopts a tower structure and is equipped from top to bottom with a vertical-shaft impact sand maker, circular vibrating screen, powder selection equipment, return device, and material conveying equipment, forming a complete fully automatic closed-loop production system.
The core system uses a five-channel rotor structure to achieve 65~70 m/s high-speed throwing. Based on a stone-on-stone centrifugal crushing principle, it efficiently crushes, shapes, and grinds raw materials to produce manufactured sand with excellent particle shape and precise grading.
The sand yield reaches 75%~80%, fineness modulus can be stably adjusted from 2.2~3.0, powder content can be flexibly controlled from 3%~15%, and the quality of manufactured sand is far above natural sand.
Manufactured sand is a core raw material for high-performance special mortar, self-leveling floor materials, tile adhesive, grouting materials, and other high-end building-material products.
Application Fields
It is suitable for commercial manufactured sand production for mortar companies and concrete batching plants, raw material preparation for self-leveling mortar and high-performance tile adhesive, and high-quality fine aggregate for precast components.
It also serves raw materials for grouting materials, repair mortar, and other special building materials, industrial sand preparation for glass and casting, and supporting dry mortar production lines to achieve self-supplied sand sources.
Core Advantages
Excellent finished sand quality: needle-like and flaky particle content is ≤3% in some working conditions and ≤5% in others, cubic particle ratio is ≥92%, and grading complies with Zone II standards.
Precisely adjustable fineness modulus: the 2.2~3.0 range is stably adjustable, and powder content is flexibly controlled from 3%~15% to meet different formula requirements.
High sand yield and strong economics: sand yield reaches 75%~80%, 20%~25% higher than traditional sand makers, while unit power consumption is reduced by 10%~15%.
Tower structure and very small footprint: the vertical layout fully uses space and reduces civil construction investment.
Full-process negative-pressure environmental protection: integrated dust collection and fully enclosed negative-pressure operation prevent dust overflow and meet strict environmental requirements.
Variable-frequency speed control and wide operating adaptability: variable-frequency speed control suits materials with different hardness, such as limestone, granite, and basalt, and supports 24-hour continuous production.
Low operation and maintenance cost: wear-part abrasion is reduced by more than 30%, and peripheral guard plates can be reversed for reuse to extend service life.
Process Flow
Raw material of 5~15 mm stone -> belt conveyor feeding into the sand maker -> five-channel rotor high-speed throwing at 65~70 m/s -> stone-on-stone centrifugal crushing and shaping -> circular vibrating screen grading -> powder selection airflow classification -> qualified manufactured sand entering the finished-product bin -> unqualified material returning to the sand maker -> full-process negative-pressure dust collection.
