Raymond Mill

Raymond mill, also known as Raymond or tilting Mill, is a company in the past produced some extent, can replace the mill's efficiency, the use of closed-loop high fine milling equipment. Raymond mill is composed by the host, analyzers, blower, finished cyclone, cyclone powder and wind pipe. Among them, the host from the rack, inlet volute, blade, ground cover composition.

Raymond mill adapts to small and medium sized mining, chemicals, building materials, metallurgy, refractory materials, pharmaceuticals, cement and other industries and fields, were grinding materials processing mining products, such as gypsum, talc, calcite, limestone, marble, barite, dolomite, granite, bauxite, iron oxide red, iron ore and so on. Its processing of materials in the product fineness 613 microns to 440 microns (0.613 mm -0.44 mm), through joint action analysis machine and fans can meet different requirements of users.

Raymond Mill is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, lime, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass , Insulation materials such as Mohs hardness of not more than 9.3, the humidity of 6% in the following non-flammable and explosive minerals, chemical, construction and other industries more than 280 kinds of materials, high-fine powder processing, R-Raymond Mill finished Particle size 80-325 mesh within the arbitrary adjustment, part of the material up to 600 head.

The difference between Raymond Mill and Ball Mill

Raymond Mill and Ball Mill are also used as grinding equipment, but in fact there are a lot of different, the most significant difference is that Raymond Mill grinding powder is more than the ball mill. What is the difference between the two? Or listen to SBM for your thin talk.

First of all, Raymond Mill and lattice ball mill are grinding machine or grinding machine, but the grinding fineness difference is relatively large, Raymond mill than the ball mill fine and more.

The grain size of the lattice type ball mill is fast, the particle size of the crushed material is relatively coarse, the particle size of the ground product is 0.3 ~ 0.2mm or -0.074mm, and the mass fraction of grain grade is 45% ~ 65%.

Raymond milling machine powder is superfine grinding equipment, the mineral raw material grinding fineness can reach 2μm below. Conventional grinders can not meet these requirements. Raymond Mill's outstanding advantages are: stable performance, easy operation, can be reduced, the product size adjustment range, which is used for some moderate hardness of the following non-metallic fine grinding.

Raymond milling machine feed size is generally 15 ~ 20mm, grinding product size is usually 0.044 ~ 0.125mm. Raymond Mill is mainly used for Mohs hardness below 9.3, the humidity is less than 6% of non-flammable, non-explosive all kinds of ore, building materials, chemical materials such as ultrafine grinding, such as graphite, talc, Stone, limestone and other materials, fine powder processing, finished fineness up to 2000 mesh, in some of the fineness of the material requirements of the project and the project more appropriate.

Ball mill is mainly used for Mohs hardness below 7, humidity below 6% of the material, widely used in black and non-ferrous metal processing, fertilizer processing, refractory processing and silicide manufacturing, the material can be dry, wet Of the grinding, the finished fineness of up to 425 mesh, commonly used in the mineral processing line for the grinding of materials for the production line to prepare a process.

There are many types of equipment, such as grinding equipment, including ball mill, rod mill, Raymond Mill, ultra-fine grinding, tricyclic medium-speed micro-grinding, high pressure Powder machine, high-strength milling machine and other equipment, each kind of equipment corresponding to different needs.

Cause Analysis of Powder Dusting in Raymond Mill

Raymond Mill is the grinding equipment commonly used in the production line, grinding equipment in the production operations in particular we need attention is the amount of dust, because of its operating environment and the physical health of the operator is particularly large. So SBM Raymond Mill on the control of dust attaches great importance.

But in the visit between the SBM found that some users Raymond Mill not only failed to control the amount of dust, but also appeared Raymond Mill feed port powder spray phenomenon. What is the reason for the appearance of the equipment into the mouth of the problem of powder? Want to identify the reasons, SBM milling engineers from the following aspects to start its inspection and analysis.

1, first check the thunder of the two wind turbines are closed. Raymond mill is the use of circulating wind design, under normal circumstances, the mill should be the inlet to the ventilation, the outlet out of the wind, the throttle closed air flow caused by the cycle, The

2, dust box on the bag must be kept breathable, beat once a day. The main role of the bag for the dust, cooling, exhaust.

3, check the link to the milling machine to see if there is a leaky place. Pipeline on the leak is to suck the wind, not out of the wind must be carefully checked.

SBM Raymond Mill adopts the advanced structure of similar products at home and abroad and is updated and improved on the basis of the same industry. The equipment is more efficient than ball mill, low power consumption, small footprint, one-time investment small. And the aircraft of the wind air flow is in the fan - grinding shell - cyclone separator - fan circulation operation, so more than high-speed centrifugal grinder dust, operating workshop clean, the environment pollution.

How to solve the problem of high temperature of Raymond Mill

Raymond Mill is the milling industry in the common milling equipment, for many people is no stranger. Equipment in the use of a period of time, there will always be more or less the problem, do not be afraid of the problem, find a solution is the key. Today, SBM and we are talking about the high temperature of Raymond Mill is the problem.

Raymond mill temperature is too high, including the fan motor heat and bearing the temperature is too high and other different phenomena, the user in the face of Raymond Mill problems are too high, the first to clarify the reasons for the temperature rise, and then the right medicine The

Raymond Mill in the daily production of many problems are due to improper maintenance caused by, so we recommend that regular maintenance to ensure that equipment life extension.
