Grinding Mill Equipment Used in Tephros Production Line

Various kinds of rock grinding mill included in tephros production line, like ball mill, vertical roller mill, ultrafine mill, Raymond mill and so on. SBM will provide high efficient milling machine for sale.

Tephros Introduction

Tephros refers to the rubbles and mineral particle materials thatget from volcanic eruption and the diameter is less than 2 mm. It looks like dust and the color includes dark grey, light grey, yellow and white. In the process of volcanic exploding, solid rocks and lava will be broken into fine particles which will develop into tephros. It has the volcanic activity, namely, under the general temperature and water, it can react with lime to generate the hydrates. These hydrates have hydraulic gelation ability. Therefore, they can be milled into powder and used as mixture materials to make cement.

Tephros Production Line

Tephros is similar with limestone, and the limestone production line can be used as the tephros production line. In the tephros production line, it might include these stages: feeding; primary crushing; grinding; screening and washing. All these processes need different machines to complete the related stages. The vibrating feeder is mainly used in the first stage for feeding tephros from the production site into primary crusher. When the materials are taken into the primary crusher-jaw crusher, they will be crushed into small size. It is the first breaking stage. In jaw crusher, the tephros will be crushed into small size.

After the crushing process, it comes to the most important stage-grinding mill process. As we all know, the tephros can be used as the construction materials to build high buildings, railways or other industries. So it will need the fine size tephros materials. Grinding mill production machine can help to realize this requirement. In this stage, the crushed materials will be grinded into fine powder. Through the screening process, vibrating screen can separate the related large scale tephros materials and take back to the grinding mill to process again. In the end, sand washing machine can wash the undesired materials from end products to get clean and fine powder tephros materials.

Basic Tephros Production Line Performance Introduction

This tephros production line has high automation degree. Besides the general power down time and routine maintenance, the whole production line does not need the manual operation. It has high efficiency, low operation costs, large output and high yielding, the uniform finished size, and good grain shape. It can reach the national construction materials requirements.

Tephros Grinding Process

Grinding is the process of breaking crushed materials into fine powder size. Through the bucket elevator, the materials will be taken into the storage bin and then will be taken into the main grinding machine evenly through the electro-vibrating feeder. The materials will be scooped up into the grinding roller and ring space to be grinded. Blast blower will take the air into main grinding body and take the particles into separating room. Through the separation process, large scale materials will be taken back to grinding room to be grinded again. The qualified fine powder will goes into the finished product cyclone powder with air.

Vertical Roller Mill Used In Tephros Grinding Process

Vertical roller mill is the new type grinding mill used in tephros grinding process. It is produced by SBM's professional experts. This kind of machine occupies high technology and is based on over 20 years' grinding mill production experience. It combines the drying, grinding and separation processes into one unit. This will simplify the production line and the plant layout. It operates at a low noise level and the outdoor installation is feasible. It can reduce the civil construction costs and improve the working environment.

Vertical roller mill is the main grinding machine used in tephros grinding process and it can realize high production ratio with less operation costs.
