investigating windmills can help encourage observation, recording and deduction. to relate the shape and size of windmills to their function, and how they have changed over the years. to provide the three-dimensional evidence to reconstruct how the building was used. pupils understand the social and working conditions in the past
Learn MoreOur products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
unauthorized modification may impair the function andor safety and could affect the life of the equipment. there are specific applications for which the windmill was designed. always check of damaged or worn out parts before using the windmill. broken parts will affect the windmill operation. replace or repair damaged or worn parts immediately
