Under current circumstance, the crusher industry has good development tendency and it has become a both traditional and new field that means the opportunities and challenges are coexisting.Besides so many superior features, ring hammer crusher also has wide application range: the ring hammer crusher is suitable to crush various brittle rock and ore materials with medium hardness such as limestone, coal, salt, gypsum and coal gangue. And ring hammer crusher is usually applied to industries like cement, coal dressing, electricity generating and construction materials. It can crush raw materials with different sizes to even granularity so as to supply satisfactory materials to different projects.And for vertical shaft impact crusher, the maintenance work is also very important.

1. The user had better open the watching door and inspect the abrasion inside the crusher regularly. But it is prohibited to open the watching door when the machine is working. Besides, if there is any abrasion on the impeller and other spare parts, the user has to replace them in time.

2. The tensioning force of the triangle transmission belt should be adjusted appropriately. When the double motors are driving, the triangle belts on the two sides should carry out the group selection to make the length of each group consistent as far as possible. This can guarantee the high efficiency of sand making machine equipment.

3. After the sand making machine works for 400 hours, the user has to add moderate lubrication grease. And the user has to replace a new bearing after the machine works for 7200 hours.

4. During the process of operation, the operating staff should pay special attention to the safety because vertical shaft impact crusher belongs to high-speed operating equipment.

Fote has grasped the opportunity to develop a new kind of hammer crusher which absorbs the advanced technology from Gemany. This hammer crusher has become the core crushing equipment because it can replace the traditional stone crushers totally.
