Working principle of linear vibrating screen

The linear vibrating screen uses the vibration motor as the source of vibration power, so that the material is thrown up on the screen while moving forward in a straight line. The material enters the inlet of the screening machine evenly from the feeder, and generates data through the multi-layer screen. The oversieve and undersieve […]

Introduction to the performance of banana vibrating screen

The banana vibrating screen is a self-synchronizing heavy-duty equal-thickness screen. The screen box is similar to the shape of a banana. The screen beam adopts a box-shaped beam. The vibrator and the exciter are connected by an intermediate transmission shaft. Banana vibrating screen is widely used in coal grading, desliming, dewatering, de-intermediation, and can also […]

Application of ceramic casting sand in casting process

The lost foam casting process is suitable for a large number of castings that have intricate structural features and are difficult to produce by other methods. From the actual situation of developed countries, such as the United States and several European countries that have lost foam process operations, this view is true. Lost foam process […]

What are the classifications of the lost foam casting process?

Lost foam casting is a method of casting a refractory bonded paint, drying it and then performing dry sand molding, vibrating tightly, and then pouring the molten metal to heat the gasification to disappear, thereby obtaining a metal part having the same shape as the pattern. Lost foam casting is a new technology with no […]

Analysis of lost foam casting process of aluminum alloy

Lost foam casting has strong vitality because of its quick and good green environmental protection characteristics. Especially in recent years, the development momentum has the potential to break the bamboo. The lost foam casting process has precise casting shape and almost no allowance, which is in line with the lightweight and precise casting. The development […]

What is casting?

Casting is a process in which a metal is smelted into a liquid that meets certain requirements and poured into a mold, and cooled, solidified, and cleaned to obtain a casting having a predetermined shape, size, and performance. Casting blanks are near-formed to achieve machining-free or small-scale processing, reducing costs and reducing time to some […]
