Linear Sieving

Sievmaster Segregator Range

The Segregator Range works by using a pair of vibratory motors to move product along a large rectangular mesh screen in a linear direction. The larger surface area is especially useful for de-dusting, de-watering, and screening delicate product.

What is the Sievmaster Segregator sieve?

The Segregator is suitable for separating both wet and dry product. The large screen area allows the product prolonged sieving time, and the sealed linear vibration system gently but positively presents the product to the mesh to ensure the material is efficiently screened. 

Segregators are ideally suited to screening light, fragile products with low bulk densities. They are the used for dealing with products with a very high percentage of oversize, such as removing small broken pieces from larger particles, due to the outlet being the full width of the sieve.

The Segregator Range is available with variations to provide up to 3 separations and a wide choice of sieving aids for problem materials.

Features & Benefits

  • A very high sieving efficiency
  • Adjustable screen inclination to raise the oversize outlet
  • Easy-Clean, hygienic design
  • Wet or dry applications
  • Dust and waterproof to at least IP65
  • Conforms to CE, UKCA, FDA, EC 1935/2004 and ANIA regulations
  • Quick change, bonded screens
  • Low maintenance/running costs – tool free disassembly & minimal servicing
  • Linear motion is ideal for screening, grading, de-dusting, de-watering, and liquid separation
