High pressure suspension mill grinding chamber shape and liner abrasion relationship:

For powder grinding mill machine, different powder grinding chamber determined different liner abrasion condition for the same kind powder grinding mill.

High pressure suspension grinding mill grinding chamber abrasion has the following analysis:
a. During high pressure roller mill start working process, transport to the machine parallel zone will stack too much raw material at the feed opening, later will decrease sharply. Thus, parallel area suffering strong abrasion and high pressure suspension mill working several day, parallel area will be change gradually.
b. With liner board abrasion and powder grinding chamber layout change degree, along the powder grinding chamber height grinded raw material with uniform distribution. In liner limit abrasion range all the machine exist grinding chamber layout size change condition, especially later period hasn't parallel area, the whole grinding chamber completel lost organic layout. Besides, feed opening size about decrease 1.4-1.7 times, feed opening processed the most raw material. As without parallel area make output products with bad quality, the production capacity will be decrease.

In a word, as high pressure suspension mill uneven liner abrasion, powder grinding chamber will lost organic shape, lead to liner with lower using life and decrease technical economical standards.

What's raymond mill plum frame function and deform reason?

Plum frame is raymond mill main spare parts, plum frame generally adopt high hardness, good wear resistance material made, such as hard nickel-iron, high chromium cast iron, high manganese steel, etc. In addition to plum frame raw materi, manufacturer and process method are also important, for example, hard nickel-iron rollet sleeve using metal mold or centrifugal casted, hardness is 700HB, using sand mold casted hardness is 500HB. Plum frame position: grinding roller connect plum frame. Plum frame bottom is blade barrel, blade barrel fixed on plum frame, raymond grinding mill main host bottom have a big recoil bearing, so, raymond mill main shaft won't fall off, plum frame at main shaft top and be fixed.

Generally condition, as long as raymond mill normal working, there is no hard material fall into the grinding area and stumble main shaft, plum frame won't be deform. Raymond mill main host through transmission device drive center shaft rotation, center shaft top connect plum frame, roller shaft installed on the plum frame, plum frame drive by main host transmission device and fast rotation, grinding ring fixed, electric vibrating feeder make raw material fixed quantity, uniform and continous feeding to grinding chamber, grinded by grinding roller and grinding ring force. As airflow from grinding ring bottom tangentially inhalation, through grinding roller and grinding ring grinding area, inclusion powder dust feeding raymond mill top wind classifier. Plum frame top installed three grinding roller, not only revolving around the central axis, but also grinding roller itself due to friction rotation. Thus, through friction and raw mateiral sedimentary lead to plum frame unstable working.

How does raymond grinding mill grinding tooth incline degree form?

Grinding roller is powder grinding mill important part, grinding roller grinding tooth incline degree has critical role on products quality, outlet powder rate and grinding roller using life. General raymond grinding mill grinding tooth incline degree is the two grinding roller opposite rotation and press raw material, if grinding tooth has no incline degree, high speed and low speed roller grinding tooth will parallel to each other, when grinding, between two roller will appear unstable, wrong joggle phenomenon, like this, it's difficult to cut raw material to filamentous, at the same time, grinding roller will produce vibration and influence grinding effect. Raymond grinding mill grinding tooth should not only have incline degree, but also should be right installed.

Raymond grinding mill two roller grinding tooth at grinding area both side, relative to material form many crosspoint, under grinding roller rolling distance smaller than raw material formed coverage length condition, raw mateiral at crosspoint suffering bigger shear force. When raymond grinding mill grinding area with many crosspoint, grinding area material suffering shear force average chance will increase, equipment crushing ability will increase.

Under other same condition, big incline degree produce many more crosspoint in grinding area, material in raymond grinding mill grinding area will suffering stronger crushing degree, fragile cortex, bad products quality and low energy consumption. But to meet low energy consumption requirements, it should select bigger incline degree.

Vertical grinding mill wearing parts:

Blade, grinding roller, grinding ring are raymond grinding mill wearing parts.
1. Vertical grinding mill blade main used to material continue shovel into between grinding roller and grinding ring. When continue shovel up material, blade bear different quality, hardness material carry out long time contact friction, very easy suffering wear and tear, serious damaged blade can't shovel up material, lead to vertical grinding mill working efficiency suffering a certain degree effect. Thus, raymond grinding mill blade structure majority made by good wear resistance steel, make sure blade achieve the longest using life.

2. Vertical grinding mill grinding roller and grinding ring is the whole equipment wearing parts, after material transported between grinding roller and grinding ring, it will be pressed by grinding roller and grinding ring and rotarion force to achieve crushing function. So, grinding roller and grinding ring not only suffering material friction, but also suffering each other friction force. When grinding roller and grinding ring appear serious abrasion or uneven abrasion, it will effect material fine powder production, appear final products with uneven fineness phenomenon. To make sure final products fineness, vertical grinding mill grinding roller and grinding ring adopt high pressure high toughness wearable steel material, made the machine with much more widely application and for many kinds raw materials have better grinding function.

Raw material effect raymond grinding mill grinding roller tooth number:

Raymond grinding mill gear tooth number has relative to grinding materials size, raw materials feeding capacity and requirements to achieve grinding degree. For example: if raw material with big size, feeding capacity or require outlet products with big size, the machine should configurate less tooth number; otherwise it should configurate more tooth number. Under the same other condition, the fewer teeth grinding rolls, the greater the distance between the two grinding teeth, tooth groove deeper, only suitable grinding big raw material size. If using raymond grinding mill grinding fineness raw material will made raw material insert tooth groove and can't be grinded. The more the grinding roller tooth, the smaller the distance of the grinding tooth, more shallow the tooth groove and only suitable to grind small size raw materials. If using raymond grinding mill grind big size raw material, when feeding capacity is small, raw material size will be grinded too small, when feeding capacity is big, raw material media part won't be completely grinded. Grinding tooth will easy abrasion, low production and high energy consumption.

Raymond grinding mill production proved: compared with more gear tooth, fewer gear tooth will save much more energy, lower grinding temperature, longer grinding roller using life, can adapt high feeding capacity.

Raymond grinding mill structure and working advantages:
