2000 Mesh Carbon Black Micro Powder Grinding Mill with Cheaper Price

Product Introduction

LYHM ultra-fine grinding mill is especially suitable for producing ultra-fine powder. With years’ accumulation of experience in R&D, the LYHM Ultra-fine Grinding Mill is a new ultra-fine pulverizing equipment designed by Longyi. This mill is widely used to grind any non-metal minerals with Moh's hardness below 7 and moisture below 6%, such as talc, calcite, calcium carbonate, dolomite, bentonite, kaolin, graphite, carbon black, etc.

LYHM Ultra-fine Grinding Mill features in space-saving, completeness, wide usage, easy operation, smooth performance, high performance-cost ratio and high efficiency. LYHM1100 Grinding Mill is the top-rank ultra-fine circle-roll grinding mill in China.

Working Principle

The pre-grinding raw material will be crushed into particles ≤20mm, transported to the feeding hopper by the elevator, then fed into the grinding chamber by the feeder. The grinding rollers equipped on the rotary table rotate around the center shaft. There is a flexible gap between the roller and ring. The rollers rotate outward driven by the centrifugal force to compress the fixed ring. The rollers also self-rotate around the roller pin. There are four layers. When material passes through the gap, it will be smashed by the rotating rollers. It will be grinded 1st time when passing the 1st layer of roller and ring. Then grinded second, third and fourth time when falling through each layer. Thus, the material is grinded sufficiently. The powder fallen down onto the bottom table by gravity will goes up to the classifier for separation by the airflow from blower. The qualified fineness powder passing from the classifier will be collected in the bag impulse chamber as final product, while unqualified one fallen down will be re-grinded till it is qualified. The wind path is in circulation and the airflow is in negative pressure. No dust will escape out, so our equipment can ensure a no dust operation environment.

Application

LYHM Ultra-fine Grinding Mill is widely used to grind any non-metallic minerals with Moh’s hardness below 7 and moisture below 6%, such as talc, calcite, calcium carbonate, dolomite, bentonite, kaolin, graphite, carbon black etc.. This kind of mill is especially suitable for ultra-fine grinding. The fineness can be adjusted from 0.045 mm (325 mesh) to 0.005mm (2500 mesh), whose range is much wider than that of traditional Raymond Mill.

Structure

LYHM Ultra-fine Grinding Mill consists of main mill, classifier, blower, belt feeder, storage hopper, pipe system, Bag impulse dust collector, gearing system and electric control cabinet.

Main Technology Parameters

Note: The capacity is for calcite powder (Feeding Size≤10mm), and specification is just a reference. The actual production depends on these materials being processed.

Technical Advantages and Features

1. Reliable Performance

Higher production capacity and lower power consumption:

Nonmetallic mineral particles feed which feeding size is less than 10mm, can be one-time processed as<10 m powder (97% passing). The particle size less than 2um accounted for about 40%, which contributes to a larger specific surface area. It has the advantages of low cost, high efficiency, and good product fineness.

2. Unique Classifying System

Wide fineness and flexible adjustment: the fineness can be adjusted flexibly from 40 um (325 mesh) to 5 um (2500 mesh). Products with various fineness can meet the market needs and improve your competitiveness.

3. Environment-friendly: Bag impulse Collecting System

Environmental protection: Bag impulse Collecting System will remove 99.9% of the dust, ensuring dust-free operation environment. The pulse dust collection system is invented by Longyi to comply the environment protection requirements.

Thorough Cleaning：Bag impulse Collecting System is adopted with pulse-jet type of cleaning. By utilizing the compression air to clean each filtering bag. High and complete dust cleaning. Dust accumulated on bags is prevented.

4. Lower Wear-resistance Rate

The wearing parts (roller, pin and ring) are made of special wear-resistant material which prolongs their working life.

5. Absorb Vibration and Compact Structure, high safety and reliability

The mill base is inblock casting, which ensures the structural strength and alleviates vibration.
