Zinc Sulfate (ZnSO₄) Production Plant & Complete Production Line Equipment

Production Line Basic Information

We provide full‑turnkey Zinc Sulfate (ZnSO₄) production plant and complete zinc‑salt chemical production equipment for global chemical investors. Our ZnSO₄ production line adopts mature acid leaching reaction, impurity removal, evaporation concentration, cooling crystallization, centrifugal separation and drying process. Using zinc‑containing raw materials to produce multiple specifications of zinc sulfate, including heptahydrate zinc sulfate, monohydrate zinc sulfate and anhydrous zinc sulfate.

The whole production system consists of raw material pretreatment unit, acid reaction tank, purification & impurity removal system, evaporation‑crystallization unit, centrifugal separation equipment, drying system, crushing and screening station, dust removal system and PLC automatic control system. Customized production capacity is supported. Continuous production process strictly controls heavy‑metal impurities, crystal form and particle size, complying with international standards for industrial‑grade, fertilizer‑grade and feed‑grade zinc sulfate.

Core Production Advantages

• Multi‑specification product output: Optimized evaporation and crystallization technology can stably produce heptahydrate, monohydrate and anhydrous zinc sulfate, uniform crystal particles and low heavy‑metal content.
• High raw‑material utilization rate: Closed‑loop circulation process reduces material loss, improves comprehensive yield and effectively lowers long‑term plant operating costs.
• Full‑automatic PLC intelligent control: Real‑time monitoring of reaction temperature, pH value, feeding volume and crystallization parameters, reduces manual intervention and supports long‑term stable continuous operation.
• Flexible grade conversion: Adjust process parameters to switch between fertilizer grade, feed grade and industrial grade zinc sulfate to meet diversified market requirements.
• Environment‑friendly clean production: Equipped with complete tail gas absorption, wastewater recycling and dust removal facilities, low emission and meets global environmental‑protection regulations.
• Anti‑corrosion durable equipment: Core reaction, purification and crystallization units adopt special anti‑corrosion materials, long service life and low maintenance workload.

Main Applications of Zinc Sulfate (ZnSO₄)

Zinc sulfate manufactured by our turnkey plant is widely used in various industrial fields:

• Agriculture & fertilizer industry: Essential zinc fertilizer, supplement zinc element for crops, prevent zinc deficiency and promote crop growth.
• Feed industry: Feed‑grade additive, provides zinc nutrition for livestock and poultry breeding.
• Electroplating industry: Main raw material for zinc electroplating, ensures uniform and compact plating layer.
• Chemical industry: Raw material for manufacturing other zinc salt products, used as catalyst auxiliary and precipitant.
• Water treatment industry: Water quality regulator and auxiliary additive for industrial wastewater treatment.
• Textile & leather industry: Used as mordant for textile dyeing and tanning auxiliary agent in leather processing.
