Valmet Chip Bin VB
Valmet Chip bin VB is a conical chip bin primarily designed to handle raw materials with favorable flow characteristics, normally seen with a even sizes and shape distribution. It should also be relatively free from impurities such as sawdust, shavings, bark and pin chips since their presence greatly increases the risk of bridging, especially when used with pre-steaming.

Producing quality MDF requires chips that are as free from impurities as possible. Debarking and screening are not enough. Chip washing is essential for producing board of low mineral content. The growing use of purchased chips, e.g. from sawmills, results in an ever-increasing need for chip washing. Existing impurities, in the form of metal, stones and sand, must be removed before the chips enter the process.
