High-frequency Screen

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Structure Analysis

High-frequency Screen consists of vibrator, pulp distributor, screen frame, frame, suspension springs and sieve and other components.ZGPS Series are high-frequency screens and engineered to provide higher production capacities and more efficient sizing compared to conventional screens. High-frequency screens feature aggressive vibration applied directly to the screen that allows for the highest capacity in the market for removal of fine material, as well as chip sizing, dry-manufactured sand and more.High-frequency Screen can used as an equipment for small scale gold miners In Gweru.

Product Application

High-frequency Screen is widely used in mineral processing, coal, chemical, brick, food, pharmaceutical, alkali, fertilizer, paper and other industries in a variety of materials dry, wet screening, grading, dehydration. Concentrator grinding and classification process for the fine grading operations, at the appropriate concentration of the feed, feed particle size (-200 mesh size fraction content), as well as demand sieve size and feed particle size is less than 30 percent of the conditions, screening efficiency up to 70% or more. Because of high efficiency, can significantly reduce the cycle load and oversize fractions of qualified content, thereby improving the mill processing capacity (generally increased by 5 to 10 percentage points). Screening process on the sieve material granularity is strictly controlled to eliminate the coarse mineral particles on the adverse effects of concentrate grade.

Product Advantage

  • High-frequency screen adopts the most advanced theory and new structure.
  • High vibrating frequency leads to high screen efficiency and big capacity.
  • Controlled by computer, every exciter specification is adjustable. Also it sets up a transient extremely vibrating force, which is quite useful in clean the screen surface.
  • Low powder consumption: High-frequency screen adopt super Elastic material, which ensure the steadiness and help to save the power.

Operational Principle

High-frequency Screen main feature is small amplitude and high frequency of screening. Different from general principles of screening equipment, because high frequency screen using high frequency, on the one hand destroyed the surface tension of pulp and fine-grained material in the sieve surface high-speed oscillation, hastened the end of useful minerals and density segregations effect, increasing the separation of granular materials is less than the probability of contact with the sieve. Resulting in a better separation conditions for the separation size is less than the material, in particular than the major grain and pulp material through the sieve with a sieve product.
