Gypsum Grinding Mill
I. Key Equipment for the Preparation of Building Gypsum Powder
In today's booming construction industry, the demand for gypsum powder, as an important cementitious material and decorative substrate, continues to grow. High-quality gypsum powder originates from the fine processing of natural gypsum ore or industrial by-product gypsum (such as desulfurized gypsum). Among these processes, grinding is the core step that determines the fineness, activity, and final product quality of the gypsum powder. A high-performance gypsum grinding mill with matching capacity is the cornerstone for gypsum deep-processing enterprises to achieve efficient and stable production and seize market share. This article will focus on gypsum grinding mills in the classic range of 30cm feed size and 20-30 tons daily capacity, deeply analyzing their applications and advantages.

II. Equipment Overview: High-Efficiency Grinding Solutions Designed Specifically for Gypsum
Raymond grinding mill
This series of gypsum grinding mills is an upgraded model of a vertical mill or Raymond mill specifically designed for the characteristics of gypsum materials. Its core design goal is to process large raw materials and crush and grind them in one pass to various finenesses required by the construction industry (typically 80-325 mesh). The 30cm feed size design means the crusher can handle large pieces of gypsum stone from the upstream crushing process, reducing secondary crushing, simplifying the process, and lowering investment and operating costs. With a capacity range of 20-30 tons/day, it precisely targets the production needs of small and medium-sized gypsum powder production lines, regional gypsum product factories, and various solid waste resource utilization projects, making it an ideal choice for achieving a high return on investment.
Equipment Core Parameters Overview
| Parameter Item | Specifications/Description |
| Maximum Feed Size | ≤300 mm (30 cm) |
| Processing Capacity | 20 - 30 tons/day (adjustable according to fineness requirements) |
| Finished Product Fineness | 80 - 325 mesh (adjustable) |
| Main Raw Materials | Natural gypsum, desulfurized gypsum, phosphogypsum, etc. |
| Main Uses of Powder | Building gypsum powder, plaster, gypsum putty, self-leveling gypsum substrate, etc. |
| Process Features | Integrates crushing, drying, grinding, grading, and conveying. |
III. Core Advantages of the Equipment
1. Highly Efficient Design for "Processing Coarse Materials to Produce Fine Powder": The ability to directly process 30cm large pieces of material significantly reduces reliance on front-end crushing equipment and the complexity of the entire production line, saving on equipment and site investment.
2. Precise Capacity, Flexible and Economical: A capacity design of 20-30 tons/day meets the basic needs of large-scale production while avoiding equipment idling or excessive investment. It is particularly suitable for startups or capacity upgrade projects, with a short investment recovery period.
3. Excellent Powder Quality and Wide Applicability: Utilizing a graded grinding principle, the produced gypsum powder has a concentrated particle size distribution, high activity, and good flowability, making it ideal for producing various building gypsum products with requirements for setting time and strength.
4. High System Integration, Environmentally Friendly and Energy-Saving: The equipment typically integrates drying and grinding, directly processing materials with a certain moisture content range. Full negative pressure operation minimizes dust overflow, ensuring a clean working environment that meets environmental protection requirements.
IV. Practical Application Case Scenarios
Scenario 1: Regional Gypsum Building Materials Plant
An Ethiopian building materials company purchases natural gypsum ore using a short-process solution of "jaw crusher (coarse crushing) + this gypsum grinding mill". The equipment operates stably, processing 25 tons of gypsum blocks daily, producing 120-mesh building gypsum powder, which is directly used in locally produced gypsum blocks and putty powder, receiving excellent market feedback.
Scenario Two: Power Plant Desulfurization Gypsum Resource Utilization Project
A Mexican environmental technology company utilizes desulfurization gypsum generated from a power plant, drying and grinding it using this series of mills. The equipment successfully processes desulfurization gypsum with a moisture content of approximately 12% into high-quality gypsum powder, with an average daily output of 28 tons. The product is sold as a cement retarder and raw material for gypsum board, achieving high-value resource utilization of solid waste.
V. Recommended Supporting Equipment and Production Line
To build a complete gypsum powder production line, in addition to the core grinding mill, we recommend the following equipment to maximize efficiency:
• Jaw Crusher: Used for primary crushing of the raw ore, breaking large gypsum pieces to a particle size suitable for mill feed (e.g., below 30cm).
• Bucket Elevator/Belt Conveyor: Responsible for the stable transport of materials between different processes. • Electromagnetic vibrating feeder: Provides uniform and quantitative feeding to the mill, ensuring stable mill operation and consistent powder quality.
• Pulse bag filter: Collects trace dust generated during production, ensuring emissions meet standards and achieving clean production.
VI. Frequently Asked Questions (FAQ)
Q1: Can this mill process chemical gypsum (such as desulfurized gypsum) in addition to natural gypsum?
A1: Absolutely. This series of mills is designed with the persity of materials fully considered. For chemical gypsum such as desulfurized gypsum and phosphogypsum, the equipment can effectively control the moisture content of the feed material by adjusting the hot air system (such as by equipping it with a hot air furnace), simultaneously completing drying and grinding. It is the preferred equipment for the resource utilization of various types of gypsum.
Q2: What fineness is the 20-30 tons/day capacity based on? Will the capacity decrease if a finer powder (such as 325 mesh) is required?
A2: The nominal capacity is usually based on the production of building gypsum powder of around 100-150 mesh. This is the most commonly used fineness range. Yes, this is a key point. When a higher fineness of the finished product is required (e.g., 325 mesh), the material needs to be ground in the grinding chamber for a longer time, and the grading system needs to be more refined. In this case, the actual production capacity will decrease accordingly. When selecting equipment, our engineers will accurately evaluate and recommend a model based on your target fineness.
Q3: How automated is the equipment and how difficult is it to operate?
A3: The equipment adopts a mature electrical control system design, enabling one-button start/stop and centralized control. Key operating parameters (such as main unit current, fan flow rate, temperature, etc.) can all be displayed on the control cabinet instruments, making operation intuitive. We provide detailed operation manuals and on-site training to ensure your workers can quickly master the equipment.
