This invention discloses an energy-saving grinding component for a sand mill, comprising an equipment housing containing a cooling tank, a grinding chamber located above the equipment housing, a spiral cooling cavity within the grinding chamber, a feeding pipe and a discharge pipe on the grinding chamber, and a cover fixedly mounted on the top of the equipment housing on one side of the grinding chamber. This invention improves the contact shearing efficiency between the grinding chamber and the material and grinding media beads through the coordinated operation of a cam, hollow shaft, grinding drum, and pin, achieving material grinding. Heat exchange is achieved between the cooling water in the spiral cooling cavity and the grinding chamber, enabling temperature control while recycling water resources. It also allows the warm water after heat exchange to quickly and thoroughly mix with the low-temperature cooling water and cooling elements, agitating the water to break up temperature stratification, ensuring the low-temperature stability of the return cooling water, and continuously guaranteeing the cooling effect. The entire process is driven by a single power source, balancing cooling efficiency and energy saving.

The utility model discloses a condensing device for water reducing agent processing belongs to water reducing agent processing technical field. The utility model is provided with cold -draf machine and cooling water tank respectively in the both sides of reation kettle, and the inside of reation kettle is provided with cold gas ring pipe and cooling rotary pipe, and through three -fold cooling path cooperation, and cold -draf machine injects cold air directly into water reducing agent inside through the exhaust port of vertical pipe, and cold air is contacted directly with material, and utilizes heat exchange to take away heat quickly, and the inside of cooling rotary pipe is kept low temperature through cold air, and rotates and stirs under the driving of motor, expands low temperature contact surface, and passes through stirring and accelerates heat transfer in material inside, and the cooling medium of cooling water tank flows around outside reation kettle, forms the barrier of " external heat preservation + cooling", reduces the heat interference of external environment to inside, takes away the heat of reation kettle wall conduction simultaneously, can control water reducing agent temperature in target range quickly, avoids the change of material property because of slow cooling.
