Silica sand drying line: efficient and energy-saving drying solution


In the dry-mix mortar, building materials production and foundry industries, the silica sand drying line is a key link to ensure the quality of finished products. The moisture content of sand directly affects subsequent mixing and finished product strength, and an efficient and stable drying line can effectively solve the problem of wet sand moisture fluctuations and provide stable and reliable dry sand raw materials for production. Tongding Machinery Equipment Co., Ltd. has been deeply involved in the drying field for many years. Its three-pass dryer technology is mature and its products are widely used in projects such as river sand drying lines, quartz sand drying lines, and sand drying lines.

Working principle and advantages of three-pass dryer


The three-pass dryer is composed of three concentrically nested cylinders. The material passes through the inner cylinder, the middle cylinder and the outer cylinder in sequence, achieving alternate drying of downstream and countercurrent flow. This structure allows it to occupy only one-half of the area of traditional single-cylinder equipment, and the outer cylinder plays a role in insulating the inner cylinder, effectively reducing heat loss. The discharge temperature can be controlled below 60°C and can be stored directly in the silo without the need for a cooling shed.

Coordinated matching of drying line and dry-mix mortar mixing line


The dried dry sand is the core raw material of the dry-mix mortar mixing line. Tongding Machinery provides a full-process solution from drying to mixing. Its silica sand drying line can be equipped with elevators, quantitative feeders, dust removal systems and subsequent mixing equipment to form a complete dry-mixed mortar production chain. The moisture content of the dried sand can be stably controlled below 0.5%, meeting the requirements of the national standard “Ready Mixed Mortar” for the moisture content of fine aggregate.
