Complete Guide to Operating Horizontal Grinding Machines: A Comprehensive Manual from Principles to Maintenance

 

The Importance of Horizontal Grinding Machines in Modern Production

In industries such as chemicals, coatings, and pharmaceuticals, horizontal grinding machines have become key equipment in the production process due to their high - efficiency processing capabilities. This horizontally designed grinding device can continuously process nanoscale materials through its precise mechanical structure, making it particularly suitable for handling high - viscosity materials or materials that require long - term grinding.

 

Analysis of the Core Working Principles

Horizontal grinding machines achieve refined material processing through kinetic energy conversion, and the entire process consists of seven key stages:

 

1.Pretreatment Preparation

Before operation, it is necessary to confirm that the grinding tank is clean and free of impurities to avoid cross - contamination. Select grinding media such as ceramic beads or stainless - steel balls according to the material characteristics. The diameter of the media is usually 3 - 5 times the target particle size of the material.

 

2.Material Loading Specification

Load the pretreated raw materials and grinding media into the tank in proportion. The amount of liquid medium added should completely cover the grinding media. Particularly, note that the loading capacity should not exceed 70% of the tank volume to reserve enough space for movement.

 

3.Kinetic Energy Conversion Stage

After the equipment is started, the main shaft drives the dispersion disc to rotate at high speed (the rotation speed usually ranges from 500 - 3000 rpm), generating strong shearing force and impact force. The grinding media and materials form a vortex motion under the action of centrifugal force, achieving efficient collision and friction.

 

4.Temperature Control Mechanism

The heat generated during the grinding process is promptly removed through the double - layer tank cooling system or an external circulating cooling device to ensure the stability of heat - sensitive materials.

 

5.Particle Size Monitoring Point

Determine the grinding progress by regularly taking samples for testing. Terminate the program when the material reaches the target fineness (usually in the micron or sub - micron level).

 

6.Separation Process

Use a dynamic separator or a screening device to quickly separate the media from the finished product. Some models are equipped with an automatic discharging system to improve efficiency.

 

7.Post - processing Optimization

Perform subsequent treatments such as filtration and drying according to product requirements. Some fine - processing operations require secondary grinding to ensure product quality uniformity.

 

Guide to Standardized Operating Procedures

 

Pretreatment Stage

- Conduct equipment inspection: Confirm the integrity of the sealing parts and the status of the lubrication system.

- Medium selection criteria: Zirconia beads are suitable for high - hardness materials, while glass beads are suitable for conventional grinding.

- Loading capacity control: Strictly follow the volume ratio regulations.

 

Operation Stage

- Startup procedure: Use step - by - step speed increase to avoid current impact.

- Parameter setting: Adjust the rotation speed and time parameters according to the material hardness.

- Process monitoring: Pay attention to key indicators such as temperature, pressure, and noise.

 

Safety Regulations

- Wear protective equipment: Dust masks and goggles are essential.

- Emergency stop device test: Verify the emergency braking function before each startup.

- Prohibit illegal operations: Overloading or private modification of the equipment is strictly prohibited.

 

Equipment Maintenance and Service Life Extension Techniques

 

1.Daily Maintenance System

- After each use, implement the "three - cleaning" standard: clean the materials, the media, and the residues.

- Check the sealing system weekly and replace any worn parts immediately.

- Lubricate the key bearing parts monthly.

 

2.In - depth Maintenance Cycle

- Check the wear of the motor carbon brushes quarterly.

- Annual major maintenance includes calibration of the transmission system and upgrade of the control system.

 

3.Fault Warning Signals

- Abnormal vibration: It may indicate bearing damage or dynamic balance imbalance.

- Abnormal temperature: It reflects a cooling system failure or over - loading operation.

- Abnormal discharge particle size: It suggests media wear or incorrect parameter settings.

 

Key Points for Equipment Purchase Decision - Making

 

1.Material Selection Criteria

- It is recommended to use 316L stainless steel or tungsten carbide coating for the parts in contact with the materials.

- In a highly corrosive environment, give priority to models with a polyurethane lining.

 

2.Production Capacity Matching Principle

- Laboratory - type: Processing capacity of 0.5 - 5L.

- Medium - sized production equipment: Tank volume of 20 - 100L.

- Industrial - grade models: Continuous production systems with a volume of over 200L.

 

3.Technological Innovation Configuration

- Intelligent temperature control system: Precise temperature control within ±1℃.

- On - line particle size monitoring: Laser particle size analysis module.

- Energy - consumption optimization design: Frequency - conversion motors can save over 30% of energy.
