Research of Raymond Mill Wear Resistant Casting Parts

As the grinding equipment, Raymond mill is widely used in the chemical industry, mining industry, construction industry and so on. It plays an important role in the production line, so improve the Raymond mill efficiency is the key to improve the capacity of production line. How to improve the Raymond mill efficiency?

Firstly, the customer should consider the grinding fineness of the Raymond Mill; long time will took with higher fineness.

Secondly, the humidity of the raw material should be considered too, because high humidity raw material will stick on the grinding roller and grinding ring, this make the Raymond mill works harder.

Thirdly, the component parts of the Raymond mill, the Raymond mill consists of the host, the motor, grinding ring, grinding roller, the failure of one of those parts will influence the efficient of the Raymond mill.

1. L Melting Process

CYK type high aluminum alloy cast iron melting inside Mid-frequency induction furnace. Melting temperature should reach to 1500~1550℃ to ensure the alloy melt and fully spread. To prevent casting organization coarse grains or appear cold-lap, wrinkled skin, casting temperature should be control in 1360 ~ 1380 ℃. Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example, elevating conveyor belt, complete equipment for cement plant. Welcome all of you to visit our official website.

2. Casting Process

High chrome alloy cast iron material has the alloy content high, good fluidity, shrinkage, poor thermal conductivity of characteristic. So in design its casting modeling process, take directional solidification principle. And in order to strengthen the riser fill shrinkage effect of castings, impact hammer, counterattack by large and thick plate castings made poured rain type insulation riser cast method.

3. Heat Treatment

Heat treatment takes much ladder hyperbolic process, it including quenching and tempering. The process parameters and closely related section thickness, producing different casting, the parameters of different.

Raymond Mill wear resistant parts important role is we should not only keep wear ability but also to protect the Raymond Mill. Therefore, In Raymond Mill wear-resistant parts development process, from material to finished products, it mainly experienced L melting process, casting process, heat treatment. After these three process, we produced high quality Raymond Mill wear-resistant parts.
