Sodium Potassium Feldspar Mill History

Who invented the Sodium Potassium Feldspar Mill?

In 1906, CVGrueber founded the Curt Von Grueber machinery factory in the southern suburbs of Berlin. Using his patents in the United States, he produced the first Maxecon mill and used it as a coal-fired equipment for the MOABIT power station in BEWAG in Berlin. The grinding energy can reach 5T/ H, sold nearly 600 units in a few years, respectively, used in the field of grinding in different industries. After E.C. Loesche became a shareholder and headed the Curt Von Grueber machinery factory, he decided to purchase the US patented raymond centrifugal ring roll mill to produce the first Sodium Potassium Feldspar Mill system.

However, since the grinding power (centrifugal force) of the Sodium Potassium Feldspar Mill coal grinding roller was limited by the diameter and speed of the grinding roller, the grinding was only applicable to soft, low ash and easy to grind coal. Materials, while Germany’s coal is harder, ash is high, and requires higher grinding power. This structure of Raymond coal mill is difficult to meet the grinding requirements, so Raymond coal mill is not popular in Germany. At that time, Raymond coal mill was suitable for the grinding requirements of American coal, so Raymond coal mill was widely promoted and applied in the United States.

Who improved the Sodium Potassium Feldspar Mill?

In 1925, ECLoesche summarized the use characteristics and structural drawbacks of the first generation Raymond coal mill, decided to further improve the grinding structure of Sodium Potassium Feldspar Mill, and developed a grinding machine with the opposite principle of grinding, called improved type. Sodium Potassium Feldspar Mill. The improved Sodium Potassium Feldspar Mill system has two modes of ventilation: positive pressure and negative pressure. This type of Sodium Potassium Feldspar Mill patent was soon purchased by Combustion Engineering. Since the improved Sodium Potassium Feldspar Mill still has the problem of ring roll grinding, although the roll diameter is slightly increased, the grinding power is not increased much.

Later, the Raymond branch of the American Combustion Engineering Company developed a new generation Sodium Potassium Feldspar Mill based on this, called VR grinding. This Sodium Potassium Feldspar Mill is similar in many respects to the structure of the current Loesche mill. It is worth noting that it differs from the Loesche mill cone and the face grinding disc, but uses a cylindrical grinding roller and a grinding disc with a 15 degree angled inclined grinding surface. The grinding rolls have a roll-out device similar to the Loesche mill during inspection and repair, and are also equipped with protective devices to prevent metal contact between the grinding rolls and the grinding disc. In addition, the grinding roller can be lifted in advance before the mill is started, which can reduce the starting torque of the motor. Sodium Potassium Feldspar Mill is commonly used in industrial applications in the United States to prepare pulverized coal. The fineness of the product varies between 250 and 325 mesh, and the product fineness and output can be adjusted during operation.

With years of development and improvement, the types and models of Sodium Potassium Feldspar Mills are also increasing. Due to the stable performance, adaptability and high cost performance of Sodium Potassium Feldspar Mills, China has been introduced by many users for many years. Praise, occupy a very important position in the crushing equipment.
