The "innate" and "acquired" advantage of Raymond mill

Article Source : 未知

Date : 2020-07-17

In large industrial grinding equipment, Raymond mill is the most widely used equipment. Its superior performance, mature technology, perfect maintenance way, many equipment models make the Raymond mill have the congenital advantage.


Equipment application

The Raymond mill is mainly used for grinding of hardness materials. It is outstanding in the non-flammable ore whose hardness is not greater than 9.3, and the humidity is less than 6%, chemical industry and construction. For example: barite, calcite, potassium feldspar, bentonite, marble, talc, humic acid, gypsum, etc.

The structure of the Raymond mill

The Raymond mill is mainly composed of main engine, analyzer, air blower, finished cyclone separator, micro-powder cyclone separator and air duct. The main engine consists of stander, inlet volute, scraper, grinding roller, grinding ring and shell.


The advantages of the Raymond mill

1. It has a wide range of grain size and can be adjusted arbitrarily.

2.The dust removal effect is completely consistent with national standards.

3.The internal grinding device of the grinder adopts the multi-stage seal with good sealing performance.

4.Stable operation and low noise.

5.Long service time and mature technology.

6.The various models can meet the needs of different customers.


The "acquired advantage" of the Raymond mill

As one of the most advanced and familiar "Raymond mill", it is a little backward compared with the iterative products of Raymond mill. At present, the iterative and upgraded products of Raymond mill, namely "offspring" -- such as high pressure grinding mill, European mill and ultrafine mill have unique advantages over the first generation of Raymond mill.



For the first generation of 5R4121 Raymond mill, the feeding size of 5R Raymond mill is less than 30 cm. The capacity is different according to the material fineness. When the output size is about 200 mesh, the capacity is between 4.5-8 t/h and the motor power is 75kw. Compared with YGM130 high pressure grinding mill, the capacity of 5R4121 is about 1.5 tons lower than that of YGM130.

Compared with the first generation of 5R4121 Raymond mill, MTW138 European mill is a new upgraded generation of Raymond mill. The feeding size can be up to 35 cm, and the capacity is nearly twice. The mill adopts the internal thin oil lubrication system, without manual for oil. Moreover, the integrated design has no reducer burden. The power consumption is low, and it is more environmentally friendly and energy saving.

Zhengzhou General Mining Machinery Co.,Ltd was founded in 2004, and it focuses on large industrial powder grinding, ore crushing and sand making areas and is skilled in the development, production and manufacturing of Raymond mill, ultra fine grinding mill, European mill and high-pressure grinding mill, impact crusher and jaw crusher. In the past 15 years, Zhengzhou General Mining Machinery has insisted on winning the market with quality, always aiming at better customer service experience, so that customers can put into production fast and return faster. Pre-sale technical personnel guides in person and provide free planning and detailed production plan. After-sales personnel installs equipment quickly in place and solves practical problems for customers at the first time. We have received more than 9000 customers.
