Raymond Mill

Raymond Mill

With the proposed of a conservation oriented and environment-friendly economy construction, domestic companies are looking for the direction. Raymond mill industry has also broad development prospects. Raymond mill is the main grinding equipment of our country powder industry. In order to meet the requirements of different application areas, the development of "energy saving, high reliability, precision, automation" is an inevitable trend. Now, Raymond mill industry development trend is belong to the steadily rising stage.

There are many machines in Raymond mill grinding system. These machines are fixed depending on the installation order. Every machine has its own function. Raymond mill grinding production system is the material working flow and the materials working flow changes. Here will learn Raymond mill working system from the composition machines,Raymond mill wear parts and the material working flow three aspects.

Machines in Raymond Mill Grinding System

Machines in Raymond mill grinding system includes jaw crusher, bucket elevator, stock bin, electric magnetic feeder, Raymond mill, cyclone collector, bag-type dust collector and pipeline and draught fan and so on.

Main Introduction of Raymond Mill Wear Parts

Raymond mill wear parts will cost most money in the grinding production line and they are the necessary parts in the grinding system. Besides, they also be used to protect the materials from worn. Here will introduce the wear parts for you all.

The wear parts of Raymond mill include grinding roller shell, grinding ring and blade. These parts are directly contacted with materials and their service life time is shorter less than the other wear parts.

Raymond Mill Wear Parts

Roller Shell:

Roller shell is installed under Raymond mill grinding roller. It is used to protect the grinding roller. The roller shell on the grinding roller can rotate feely. When the materials enter into between grinding roller and roller shell, the grinding roller will grind the materials.

Grinding Ring:

Grinding ring is installed inside the Raymond mill wall and it is a part has horizontal position with grinding roller. Grinding ring will wrap the grinding roller. When materials enter into the space between roller shell and grinding ring, the materials will be grinded into suitable size materials. Grinding ring is common in grinding machine and it will be used to grind materials and protect the machine.

Raymond Mill Blade:

The Raymond mill blade is installed on the millstone inside the Raymond mill host. Its shape is hook face and has several parts. When one part is worn seriously, the other part can be changed and be used again. It will reduce the operation costs. The main reason cause blade worn is: materials falling from grinding roller and roller shell are not grinded enough and enter into the blade area. They will be thrown by blade to be grinded again. These blades cannot move. At present, the blade is installed together and when one part is worn, the others can be used again.

Material Working Flow in Raymond Mill

Raymond mill grinding system material working flow: materials will be crushed by jaw crusher machine and then they will be taken to bin. Materials will be taken to Raymond mill through electric magnetic feeder machine. Block materials will be grinded by Raymond mill and then enter into the classifier. Through classifier, they will leave in the cyclone collector and some other materials will be entering into the bag-type dust collector. The wind powder will be lost in this collector.

Depending on the above mentioned material working flow analysis, materials stocked in bin is for the crusher crushing output is higher than grinding mill grinding output. To prevent more feeding material make the work stock, it needs to use the bin to discharge the materials. Through bin, materials can realize the stepless adjustment to feeding material. It can be used in automatic production line and realize the working automatic. It can realize the continuous and uniform feeding material. It is the best choice for Raymond mill.

Raymond mill production system has two dust removal systems: cyclone collector and bag-type dust collector. Cyclone collector will collect the dust through centrifugal force function; the materials will fall into the machine under the function of gravity. The bag-type dust collector is used to collect the left materials and discharging them out of the machine. It will promote the gas cycle.
