1. Product Description
The High Temperature Rotary Dryer is a professional high-temperature industrial drying equipment independently optimized for high-standard processing of ceramic sand, foundry sand, quartz foundry sand and casting auxiliary materials. Ceramic sand and foundry sand are core granular auxiliary materials for precision casting, ceramic production and industrial molding industries. These molding sands require extremely low moisture content, high surface cleanliness and stable high-temperature resistance to ensure casting surface quality, avoid bubble defects and improve molding qualification rate. Ordinary low and medium temperature dryers are limited by heating temperature and insufficient heat exchange intensity, resulting in incomplete deep dehydration, residual crystal water, unstable sand quality and low molding precision, which cannot meet the strict process standards of precision foundry and ceramic manufacturing. This high-temperature rotary dryer adopts upgraded high-temperature resistant furnace body structure, high-strength thermal insulation layer, high-power hot air supply system and high-temperature graded drying technology. It can provide stable and ultra-high drying temperature to thoroughly remove surface moisture, internal gap moisture and combined water of various foundry sands. The equipment features high temperature resistance, uniform heating, large single-machine capacity and stable continuous operation, effectively eliminating casting defects caused by damp sand materials. It is dedicated to high-standard drying and quality improvement for foundry sand, ceramic sand and casting aggregate materials, serving as essential core processing equipment for modern precision foundry and ceramic industrial production lines.
2. Working Principle
This high-temperature dedicated sand dryer adopts high-intensity thermal circulation and segmented temperature-control graded drying principle specially designed for foundry and ceramic sand. Wet ceramic sand and foundry sand materials are continuously and quantitatively fed into the high-temperature resistant rotary drum. The thickened thermal insulation structure and high-temperature stable operating system ensure that the internal drying temperature is accurately maintained within the set high-temperature range without heat loss or temperature fluctuation. The optimized high-strength lifting structure continuously lifts, flips and scatters dense sand particles to form a uniform and dense material curtain, enabling every single sand particle to fully contact with high-temperature circulating hot air. Through segmented high-temperature gradient heat exchange, the equipment firstly removes surface free moisture at medium temperature, and then thoroughly evaporates internal adsorbed water and residual crystal water through high-temperature intensive drying, achieving deep and complete dehydration. The intelligent high-temperature temperature control system precisely adjusts heating power and air volume according to sand humidity, particle size and process requirements to ensure that the dried foundry sand fully meets casting molding standards. Water vapor and tiny sand dust are discharged and purified through a sealed dust removal system. After high-temperature intensive cyclic drying, the finished ceramic sand and foundry sand feature ultra-low moisture, loose particle state and stable physical properties, completely satisfying the high-precision molding and casting production demands of the foundry and ceramic industries.
