Vertical Leaf Filter

Horizontal Pressure Leaf Filters

Horizontal Pressure Leaf Filters (HPLF) are frequently used in various industrial filtration processes.The primary difference between Vertical pressure leaf filter (VPLF) and HPLF is the orientation of the filter vessel – horizontally in HPLF and Vertically is VPLF

The structure of the HPLF typically consists of a horizontal cylindrical vessel containing multiple filter leafs arranged parallel to each other vertically on a common manifold.These filter leaves, the heart of the filter are made of 5 or 3 layers of metal meshes covered with woven wire mesh or a filter cloth that serves as a filtering medium.

In HPLF cake after the filtration can be discharged in a dry form or in slurry form.  For dry cake discharge pneumatic vibrator is provided and for slurry discharge type a pneumatic or electrical slicing arrangement is provided.

HPLF are used in variety of applications across many industries like food, edible oil, fertilizers, mining, pharmaceuticals and metallurgy.The choice between vertical or horizontal pressure leaf filter often depends on specific process requirements including space availability, Flow rates and nature of slurry to be filtered.


Vertical Pressure Leaf Filter

Vertical Pressure Leaf Filter (VPLF) are industrial scale filtration devices that are often used in scenarios where high flow rates are required. These are typically vertical in orientation, The design typically consists of vertical cylindrical shell, housing number of vertically mounted filter leaves, fitted on common manifold.

Each filter leaf is made of 3 or 5 layers of stainless meshes. The slurry is pumped under pressure in to the vessel. As the liquid passes through the wire mesh, the solids particles are trapped, while the filtered liquid called the filtrate, passes through into collection outlet (Manifold). The cake after filtration can be dried by passing steam or air or nitrogen. Dried cake is dislodged from bottom through a butterfly valve by a pneumatic vibrator attached to filter leaves. Slurry discharge of filtered solids is also possible through sluicing arrangements.


vibrating screen

Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening.

The screens serve to classify the different particles by size, starting from a bulk product in a continuous process. The inlet material (the raw product) advances from the part where the screen is fed to the opposite end in which the particles come out separately according to their size, shape or density. There are also vibrating screens that are loaded by the center and the product moves radially to the outputs that are on the periphery.

For the correct advancement of the product it is necessary that the process is continuous, and it is due to the vibration if the screening surface is horizontal. Most of the screens have a certain inclination in such a way that the advance movement of the product is due to a combination between gravity and vibration.
