Which reasons lead to vertical grinding mill gearings damage?

During vertical grinding mill(raymond mill) working process, we'll suffering gearings damage phenomenon, as replace new gearing is a very troublesome things, so, all users intend to reduce gearings damage condition. Through large amount of experience, we summarized the following relative gearing damage reasons:
1. Vertical grinding mill installation; machinery equipment installation premary period, as many spare parts are new products, it's inevitably suffering some accidents during installation, for old install workers, it's easy to slove all the problems as they have rich experience, but for the novice it not easy to say. Raymond grinding mill gear installation is the same, when using hammer, novice can cotrol efforts and brute force straight tip gear, lead to gear deform; There are some other questions, such as gear installed at an unreasonable position and so on;
2. During vertical grinding mill working process, working without add lubricating oil for a long time or using unreasonable lubricating oil or add oil not enough and so on;
3. Pollution is the worst damage to gear when raymond grinding mill working, so you have to clean gear per certain time, increase gear sealing device property;
4. Exhausted damage is vertical grinding mill gear common damage method. Common exhausted damage reasons: gear overload working for a long time, don't maintenance in time, improper maintenance and aging equipment and so on.

What You Should Pay Attention On High Pressure Suspension Grinding Mill Cylinder Collusion?

1. Before high pressure suspension grinding mill cylinder collusion, you should adjust new and old cylinder, new cylinder both sides surface should through formation process and add "meter" shape support or inner the support ring to make sure collusion quality, reduce welding stress;
2. When high pressure suspension grinding mill cylinder collusion, ring gap distance should more than 300mm;
3. Before replace high pressure suspension grinding mill working cylinder, stop position should be reasonable, the position can  containment cylinder deformation and confirm deformation.

Fully Airflow Crusher Knowledges:

Airflow crusher properties advantages and features:
Airflow crusher slove general crusher high energy consumption, low production capacity disadvantages, is a new generation products, technical properties completely exceed than domestic same products. Main has the following features:
1. Crushing production capacity improved 1 times than general crusher at the same energy consumption;
2. When required output product with uniform size, yield rate improved 1 times than general crusher;
3. Airflow crusher multi-function, can be used as crusher and also can be used as crusher and classifier;
4. Big feeding material size range, the biggest feeding size 5mm;
5. Automatic control, simple operation, stable working, eco-friendly and so on.

Airflow crusher application:
Airflow crusher is widely used in chemical, mineral, grinding material, refractory materials, metallurgy, construction material, ceramic, new material and other dry powder material ultrafine crushing and granule shaping.

Lime Vertical Preheater(Lime Rotary Kiln) System Components:

1. Feeding system: main contain top silo, discharging pipe, discharging methods and structure can make sure safety sealing when feeding materials to preheater, thus, cold air outside can't flow into lime vertical preheater and realize continuous and interrupt feeding by valves help;

2. Lime vertical preheater: it's make sure material preheating to around 900 degree main parts, composed by preheating chamber, suspension device and refractory liner and so on;
3. Material injection device: main contain material injection head, frame and connecting rod parts;
4. Hydraulic system: main contain oil box, oil pump, motor, solenoid valve, hydraulic oil pipe and so on, it's main function: cotrol material injection device, finish material injection task;
5. Bottom feeding chamber: main contain chute pipe, feeding chamber, feeding chute port and so on, it's main function: lead preheated material to rotary kiln to calcine;
6. Frame: main contain column, ring beam and so on, it's main function is supporting preheater top structure.

Know Cement Cooler Advantage&Disadvantage Make It Easier For Using:

Single cylinder cement cooler is one of rotary kiln system and function important cement equipment. Making rotary kiln clinker temperature from 1000-1300degree decreased to 200degree, then improve cement clinker quality and grindability.

Single cylinder clinker cement cooler -- solid countercurrent heat exchange equipment, easy operation, reliable process, stable working, high thermal efficiency, without waste gas and dust emissions, rotary kiln cement equipment, upstream and downstream using methods. Cooled air with small volume, the disadvantages: high temperature clinker is difficult to be cooled, as cooling high temperature clinker, heat consumption is big, clinker cooling degree is effected by clinker granule, so, single cylinder clinker cooler will be replaced by grate cooler.

Single cylinder rotary kiln clinker cement cooler woorking cylinder average diameter is 2---5 meter, length is 20 --- 50meters, length and diameter proportion is 10 --- 12, incline degree is 3-4%, production capacity is 25 - 35 thousand tons per year, clinker cooler discharge opening temperature is 150 --- 300 degree, high effciency is 55 --- 70%.

How to Maintain Wood Powder Making Machine?

After wood powder making machine working a period of time, there will be some questions, it's not because of wood grinding machine quality problems, it's because the operating methods or some other reasons. According kefan many years wood grinder using experience, achieved a basic solution, hope we can do help for buy wood powder machine clients. If you still have anything not clear, you can contact us at all times, we can give you much more tips:

Wood powder making machine generally fault resolutions methods:
1. Check wood grinding machine raw material fineness. If raw material with too big size or too heavy humidity, then the raw material should be deal with by wood chopper, then outlet material put into wood powder making machine to grind. If raw material with too heavy humidity, it should dry under sunshine then be crushed.
2. If raw material with fineness size, then you should remove three adjust board.
3. Cypriot file room adjustment should match with screening machine, separating final products and semi-manufactured goods. The highest production capacity allocation: 60% final products and 40% semi-manufactured goods.
4. Feeding capacity should be uniform, otherwise, wood powder making  machine motor with overload and reduce wood powder machine using life.

Cement Rotary Kiln Application&Classification:

Cement rotary kiln is calcine cement raw material to cement clinker main equipment, cement raw material through drying, preheating, calcination, cooling and so on process and then form cement clinker.
Cement kiln now can be divided two types: one is kiln cylinder horizontal position(with incline degree) and working, it's called rotary kiln; another one is kiln cylinder is vertical condition working without rotating, it's called vertical shaft kiln.
1. Wet rotary kiln, the process: add water to raw material, making the material slurry with 32-40% humidity. As the raw material is fluidity slurry, so, each raw mterial with good mixing and uniform, so, the outlet clinker with high quality, it's wet rotary kiln production main advantages.
2. Dry rotary kiln advantage is opersite to wet rotary kiln. Dry rotary kiln is making raw mateiral into dry powder with low than 1% humidity, so reduce evaporation water needs heat value.
