The screens used on the VSM 300 Shale Shaker can be easily changed out to suit operational conditions.
The following screen types are used:
Top Deck Screens (Scalping Screen)
The top deck of the VSM 300 screens utilises multi panel pretensioned screens which are used to scalp off large volumes of solids thus protecting the finer mesh of the lower deck screens. The top deck screens are retained in position by pneumo seal clamping systems which enable rapid screen change out.
Lower Deck Screens (Primary)
The lower deck screen configuration of the VSM 300 comprise four (4) multi panel pretensioned screens. All the screens are mounted on a constant 7° ramp. This screen configuration ensures consistent conveyance of solids thus minimising solids build-up. This results in a higher throughput capacity. The lower screens are retained in position by pneumo seal clamping systems which enable rapid screen change out.
Secondary Screens (Drying Screens)
Optional screen carriers are provided to enable secondary screens to be fitted to the front of the lower deck screens. This facility should be used to reduce fluid levels on cuttings when drilling with low toxicity or synthetic oil based muds. The secondary screens and carriers are fitted into ‘C’ channels and held in place by pneumo seal clamping systems which enable rapid screen change out.
