た設備増強等の費用がかかる問題を抱えていた。It is thought that the caking and cohesion phenomena causing this are caused by repeatedly dissolving and precipitating at the contact points of the particles to form a liquid bridge, and the liquid bridge becomes a solid bridge due to the action of temperature and humidity and is bonded. As a method for preventing caking, there is a problem such as flushing, which involves surface modification of particles and control of the environment, but it requires a cost for equipment enhancement and the like.
