Pepper Powder Universal Grinder Machine 7.5kw 100-300kg/h High Speed Grinding

Product Specification

Pepper Powder High Speed Universal Grinder

I, Basic structure

This crushing unit consists of a crusher, an ESC material collection box and an ESC vacuum cleaner. Solve the problem of dust flying in the material during the crushing process.

II, How it works

The working principle of this machine is that the material enters the crushing chamber and is crushed under the impact, shearing, friction of the teeth and the mutual impact of the material between the high-speed rotating movable and fixed toothed discs. After screening through the screen, it becomes the required powder.

III, Features

1. This machine uses the high-speed relative motion between the movable and fixed toothed discs to crush the material through the combined effects of tooth impact, friction and material impact with each other.

2. The crusher, the material collection box and the vacuum cleaner of this crushing unit are all made of stainless steel. Compliant with the "GMP" requirements for pharmaceutical production.

FAQ

1. Q: In what ways is this 7.5kW general-purpose pulverizer "general-purpose"? Besides pepper, what other materials can it pulverize?

A: "General-purpose" means that the equipment can adapt to a variety of materials with different properties. Besides pepper, it can typically process:

Spices: such as Sichuan peppercorns, star anise, cinnamon, cumin, turmeric, etc.

Grains: such as rice, wheat, corn, beans, etc.

Chemical raw materials and ores: such as some fertilizers, minerals, and small amounts of low-oil chemical products.

Traditional Chinese medicine: such as some dried root, stem, and leaf medicinal materials.

However, please note that for materials with high oil content (such as peanuts and sesame seeds), high sugar content, or high moisture content, pretreatment is required or the equipment material must be checked for suitability to prevent clogging.

2. Q: What are the specific requirements for the initial state of the material to achieve a production capacity of 100-300 kg/h?

A: This output range is calibrated under specific conditions. Actual output capacity mainly depends on:

Feed particle size: The material needs to be pre-crushed into smaller particles (e.g., below 5-10 mm). Excessively large lumps will lead to decreased output or damage to the cutter head.

Material moisture content: Generally, a moisture content below 6% is required. Excessive moisture will severely affect crushing efficiency and fineness, and may cause screen clogging.

Material characteristics: Hardness, fiber content, and oil content all affect output. Generally, brittle materials are easier to achieve high output than tough materials.

3. Q: How do I adjust the output fineness of this machine? What is the finest mesh possible?

A: Fineness adjustment mainly relies on changing screens with different aperture sizes. The machine's crushing chamber contains a screen ring. The crushed material is discharged through the screen under the influence of airflow. The smaller the screen aperture, the finer the output. For materials like pepper, with appropriate speed and screen size, a fineness of 60-120 mesh can usually be achieved. In addition, adjusting the feeding speed and airflow can also fine-tune the fineness.

4. Q: Will the equipment generate high temperatures during operation? Will it affect the aroma and color of heat-sensitive spices like pepper?

A: High-speed grinding does generate heat. However, this equipment typically uses the following design to control temperature:

Water cooling/air cooling system (depending on the specific model): Heat is removed from the grinding chamber through a water jacket or air duct.

Pneumatic conveying: The material is quickly discharged in a negative pressure airflow, shortening the heating time within the chamber.

For pepper, as long as the feeding speed is properly controlled, overheating of the chamber is avoided, and the cooling system is activated when necessary, its natural aroma and color can be preserved to the greatest extent. It is recommended to conduct small-batch testing before initial use.

5. Q: What are the vulnerable parts of the equipment? Are the replacement cycle and maintenance costs high?

A: The main vulnerable parts include:

Moving cutter head/hammer: Used for impact grinding, wears relatively quickly, and the replacement frequency depends on the material hardness and usage time.

Fixed gear ring/liner: Wear occurs due to friction with the material.

Screen: One of the most easily worn parts; it needs replacement when the output becomes coarser or the output drops significantly.

These parts are standard consumables, and maintenance costs are relatively controllable. Regularly checking and stocking a set of commonly used screens and cutters can effectively reduce downtime.

6. Q: What safety precautions should be taken when installing a new machine and using it for the first time?

A: Safety first. Please note the following:

Installation and Fixing: The equipment must be installed on a solid surface and secured with anchor bolts to prevent displacement due to vibration during operation.

Check Rotation: Briefly test the motor to ensure the spindle rotation direction matches the arrow direction marked on the machine. Incorrect rotation will seriously damage the equipment.

No-Load Test Run: Run the machine without load for a few minutes to observe for any abnormal noise or vibration. Only after confirming normal operation should you slowly feed material.

No Metal Impurities: Stones, metal, and other hard impurities must be absolutely avoided in the material, as they will instantly damage the cutter head and screen.

Power-off operation: The main power supply must be disconnected before any cleaning, adjustment or maintenance work.
