Superfine Grinding Mill
The ultra-fine vertical mill is currently the super-large ultra-fine grinding equipment in Asia, which has been successfully applied in the market and has mature technology. It can replace imported equipment and is an ideal equipment for large-scale production of ultrafine powder with high efficiency, high yield, environmental protection and energy saving.
It is suitable for superfine grinding of non-metallic minerals such as calcium carbonate superfine powder, limestone, barite, calcite, kaolin, gypsum, pyrophyllite and graphite. It can provide high-quality fillers and additives for industries such as papermaking, plastics, coatings, rubber inks, and chemicals.
Raymond mill working principle
It is composed of ultra-fine classifier, fan, dust collector, silo, screw conveyor, pipeline and other equipment.
Configure the classification system of secondary air separation.
The classifier and fan are controlled by frequency conversion and speed regulation, with high powder separation efficiency;
It adopts single-head and multi-head powder concentrators to effectively control the fineness of finished products.
The finished product has a wide range of fineness, from 3um to 22um, and can efficiently obtain qualified products of various specifications.
Features of Raymond mill
1.High grinding efficiency.
The roller sleeve and liner grinding curve specially designed for ultra-fine powder grinding makes it easier to form a material layer, with high grinding efficiency and high yield of one-time grinding.
2.High productivity and energy saving
The production capacity of a single machine is large, and the output is as high as 50t/h, which is equivalent to more than 5 micro-powder mills. It can save energy by 30-50% compared with ordinary mills to produce products with the same fineness.
3.Low operation and maintenance cost
The grinding roller can be turned out of the machine by hydraulic device, which is convenient for maintenance. Grinding roller sleeves can be turned over for use, prolonging the service life of wear-resistant materials, with low wear and tear. Grinding rollers and grinding disc liners are made of special materials, with long service life.
4.Low noise and environmental protection
The whole system has small vibration and low noise. It adopts an overall sealed negative pressure operation system and an air box pulse dust removal system. There is no dust spillage, and a dust-free workshop can basically be realized.
5.High degree of automation
It adopts PLC automatic control system and can realize remote control, which is easy to operate, easy to maintain and reduce labor costs.
6.Product quality is stable
The material stays in the mill for a short time, reducing repeated grinding, and the finished product has less iron content, high whiteness and purity, uniform particle shape, narrow particle size distribution, small cut point, good fluidity and strong adaptability.
7.Product quality is stable
The material stays in the mill for a short time, reducing repeated grinding, and the finished product has less iron content, high whiteness and purity, uniform particle shape, narrow particle size distribution, small cut point, good fluidity and strong adaptability.
8.Low comprehensive investment cost
Integrating crushing, drying, grinding, grading, and conveying, the process flow is simple, the structure layout is compact, and the floor space is small, only 50% of the ball mill. It can be arranged in the open air, the construction cost is low, and the investment cost is directly reduced.
