Screenex Spray Nozzles

Controlled Water Distribution for Efficient Screening

Screenex Spray Nozzles are engineered to deliver precise, efficient water distribution for wet screening, washing, rinsing, and dust suppression in mining, quarrying, and mineral processing operations. Correct nozzle selection plays a critical role in controlling spray coverage, droplet size, impact force, and water velocity, directly influencing screening efficiency, blinding control, and overall process performance.

Manufactured from wear-and corrosion-resistant materials, Screenex spray nozzles are designed to operate reliably in abrasive slurries, high-pressure systems, and chemically aggressive environments. A wide range of nozzle types, spray angles, and flow rates ensures optimal water usage while maintaining consistent coverage across screen decks and process equipment.

Applications

Screenex Spray Nozzles are used throughout mineral processing plants for:

♦ Wet screening and media cleaning
♦ Screen deck washing and blinding control
♦ Material washing and rinsing
♦ Dust suppression
♦ Chutes, feed boxes, and transfer points

They are widely applied in mining, quarrying, coal, and mineral processing operations, where water control is critical to maintaining throughput and product quality.

Screenex Spray Nozzle Systems

Screenex offers several specialised nozzle designs to improve ease of use and maintenance:

♦ DC Nozzle (Patented Screenex Product)
Self-cleaning design allows the nozzle to be cleared by twisting the adjuster during operation—no removal required.
♦ Jumbo Nozzle
Designed to operate efficiently in the 1.8–2 bar pressure range for high-flow applications.
♦ Splash Master
Available in ¾” and 1½” BSP threads, with spray angles of 60°, 90°, 120°, and 180°. Standard nozzles can be drilled to custom sizes.
♦ Quick Click System (Patented Screenex Product)
Prevents stripping of fine threads during cleaning, using a one-time adapter with a replaceable nozzle.

All spray nozzles are manufactured with standard BSP threading to ensure compatibility and ease of installation.

Spray Nozzle Selection Guide

Selecting the correct spray nozzle depends on process objective, material characteristics, and operating conditions.

Key Selection Criteria

1. Process Objective

  • Media cleaning and blinding control
  • Material washing or rinsing
  • Clay dispersion or fines removal
  • Dust suppression

2. Material Characteristics

  • Particle size and distribution
  • Clay or sticky content
  • Abrasiveness
  • Moisture content

3. Operating Conditions

  • Available water pressure
  • Required flow rate
  • Desired spray impact
  • Coverage area and nozzle spacing

Correct nozzle selection improves screening efficiency, water control, throughput, and equipment life.
