Vertical hammer mill
MV series mills are used for the fine or ultrafine grinding of a large number of materials with low to moderate hardness and abrasivity, such as for example corn, oats, barley, soya etc.
These mills are fitted with a vertical shaft rotor rotating at high speed to which hammers are fastened rigidly. The material is ground by impact and rubbing against a screen.
LaMec Italia vertical mills are machines designed and produced with extreme sturdiness and attention to detail.
Description for vertical mill
The vertical mill is a very compact machine designed to take up less space and offer the user a high level of production capacity with reduced energy consumption.
The advantages of using the vertical mill in production, as opposed to the horizontal shaft version, are as follows: reduced electricity consumption: when compared to horizontal hammer mills with the same capacity, energy consumption is on average 25% lower.
LaMec vertical mills are available in three versions:
- Limited airflow: it is not necessary to have a specific suction line for the mill in the grinding chamber. This results in
significant energy savings and limited product moisture loss during the grinding stage.
- Easy to replace screens and hammers: parts subject to wear (hammers and screen) are hooked to make their
replacement really easy.
- Easy to clean and inspect grinding chamber
Technical characteristic
The mill is fitted with a dispenser with stone and metal removal system.
The impeller features high mechanical reliability thanks to two supports with independent bearings.
The motor and impeller are connected with a flexible coupling.
High safety standards: bearing temperature is monitored by PT 100 sensors and a vibration detection system may be installed (optional).
Quieter than the horizontal mill
Construction in compliance with ATEX 22 standards.
