Zhengzhou Mingde Mining Machinery Manufacturing Co., Ltd (Central China)

Liaocheng is located in the west of Shandong Province, bordering Henan and Hebei, and at the junction of East China, Central China, and North China. It is a national historical and cultural city, an outstanding tourist city in China, a hot spring city in China, a national garden city, a national sanitary city, a dual-support model city, and a national environmental protection model city. The Yellow River and the Beijing-Hangzhou Grand Canal meet here. Liaocheng is the intersection of Beijing-Kowloon Railway and Handan-Jiujiang Railway in Shandong Province. It is the largest transportation and logistics hub spanning the three provinces of Hebei, Shandong and Henan. It is an important transportation hub, energy base, inland port and central city that radiates the junction of Hebei, Shandong and Henan. It is a core city in the eastern part of the Central Plains Economic Zone, a sub-city in the Jinan Metropolitan Area, and a central city in the economic uplift zone in western Shandong.
Sand making machine is suitable for crushing soft, medium hard and extremely hard materials. Sand making machine is widely used in many sectors such as large, smelting, building materials, highways, railways, water conservancy and chemical industries.
The material enters the sand making machine from the feed hopper and is divided into two parts through the distributor. One part enters the high-speed rotating impeller from the middle of the distributor and is rapidly accelerated in the impeller. The acceleration can reach hundreds of times the gravity acceleration, and then ejected from the three evenly distributed flow channels of the impeller at a speed of m/s. It is first impacted and broken by a part of the material that has fallen from the surroundings of the distributor, and then impacts together with the material lining in the vortex chamber. It is rebounded by the material lining, impacts diagonally upward to the top of the whirl chamber, changes its direction of movement, deflects downward, and the material emitted from the impeller flow channel forms a continuous material curtain. In this way, a piece of material will be hit, rubbed, grinded and crushed twice or even multiple times in the whirling crushing cavity. The crushed materials are discharged from the lower discharge port. During the entire crushing process, the materials impact and crush each other on their own, without direct contact with metal components. Instead, they are crushed by impact and friction with the material lining, which reduces corner contamination and prolongs mechanical wear time. The clever self-circulation of air flow inside the vortex chamber eliminates dust pollution.
The main equipment produced by Mingde includes sand making machines, sand blasting machines, sand making equipment, river pebble sand making machines, cobblestone sand making machines, roller sand making mechanisms, etc. Zhengzhou Mingde Mining Machinery Manufacturing Co., Ltd. is a large joint-stock enterprise that mainly produces heavy mining machinery and integrates scientific research, production and sales. The company is located in Gongyi Development Zone and has standardized heavy industrial plants.
