From the current situation of the crushing industry, there also a certain gaps between the foreign and domestic crushing machine. Foreign advanced ore milling equipment has an important position in the sales market of domestic crusher. To the domestic crusher manufacturer, the primary problem is to improve the product quality and the technological level of the crushing machine. This will help our country to reduce the distance between the foreign markets and create our own crusher with the excellent performance. There are many kinds of ore milling equipment in the domestic crushing market, but the traditional compound pendulum ore milling equipment is the widely used machine in the mining industry. Because the traditional crusher is featured with simple structure and easy manufacture, there are many manufacturers in the domestic market. But most of the manufacturing technologies in domestic also have a big distance with the world level. We should improve the existing technology of ore milling equipment to have a foothold in the foreign market. The performance of ore milling equipment mainly depends on the motion characteristic of the moveable jaw. The best motion characteristic depends on the good design of the structure. So, the good design of the structure of is the basis method to ensure the best performance of the ore milling equipment. The weight of domestic crusher is generally higher than the foreign machine, this is the clear gap. Even under this condition, because of the price advantage, the single machine rarely enters into the domestic market. They are generally sale the complete sets of equipment to domestic customers. If we further improve the performance of ore milling equipment, we will not only domain the domestic market, but also have the strong competition force in the international market. This is the developing direction of the domestic ore milling equipment.
