ball mill manufacturer in china

In recent years, national and social development, economic development, driven by the development of various industries, and if it is people to the food, then economic infrastructure development is inseparable from the iron and steel industry, the rise of industry, mineral processing equipment, and the machinery factory are scrambling to develop and progress. For crusher equipment selection, mill manufacturers An Qi machinery will be announced on the crusher. The principle for you, I hope you can give us some reference.

One should, according to the nature of the material and the force mechanism for ball mill manufacturer in china equipment type

In the selection of grinding equipment, grinding force should first clear the way, according to the nature of the material, and the particle size of crushed product requirements, take the corresponding force, then the type of ball mill manufacturer in china equipment.

1, large size or medium hard materials by ball mill manufacturer in china, impact, grinding tools with different tooth shapes; such as jaw crusher, roller crusher etc..

2, smaller particle size hard material by ball mill manufacturer in china, impact, milling, ball mill manufacturer in china tool surface without teeth is smooth; such as to roll crusher.

3, powder or paste material by grinding and impact ball mill manufacturer in china, such as ball mill.

4, the material of weak abrasion by impact, shock, grinding, grinding tools with sharp teeth.

5, strong abrasive material with the ball mill manufacturer in china, grinding tool surface is smooth.

6, ductile materials by using shear or fast attack; such as hammer mill.

7, the material with multiple components under impact ball mill manufacturer in china, can also be used in combination of multi force field.

Two, the mill material requirements

Dry grinding will rely on the high speed rotation of the rotor, between the rotor and the stator is fixed particles by shear stress and be crushed, or turn the piece between the fixing parts and frequent grinding. The working principle is often due to directly in contact with the materials parts wear serious, thus the ball mill manufacturer in china process is easy to produce insoluble impurities and metal particles pollution phenomenon.

Some special materials to avoid material and direct contact with the component material with corrosion resistance requirements. Generally this materials are used on austenitic stainless steel, and the hardness of austenitic stainless steel surface relative mostly metal is low, if the use of austenitic stainless steel mill pieces of material, extremely easy to produce metal particles. However, an important way to reduce the wear particle is to improve the mill material hardness, the material of carbon content in the lower the hardness is low, and high carbon material and prone to rust. Therefore, choose a pulverator piece of equipment in the material to pay attention to deal with material corrosion and the contradiction of the hardness.

To deal with these contradictions, it is necessary to analyze the contradiction between the primary and secondary, mill parts wear resistance is the main, in guarantee under the premise of ensuring corrosion resistance. For dry grinding equipment, dry material for the general case material of chloride ion is almost no precipitation, namely in the material intergranular corrosion probability is extremely low, that is to say, a selection disintegrator pieces of material must also be similar hardness lower 316L extra low carbon stainless steel. Therefore, the author suggested to select the mill material from three aspects:

1, high alloy nickel chromium steel.

2 austenitic stainless steel by special treatment, such as surgical equipment like hardening stainless steel, it is reported to have domestic pharmaceutical machinery manufacturers have a successful application example.

3, hard ceramic.

Three, the other should consider the selection principle

1, the bearing and sealing, in addition to high precision bearing selection, bearing should be multiple sealing.

2, dust powder outlet links, generally there will be a lot of dust emission, so the majority of ball mill manufacturer in china equipment (especially the classification and combination of equipment) have dust removal device. In the selection of dust to dust on the required material, according to product variety and safety degree of dust material.

3, cleaning, in addition to direct contact with material without cleaning area, should pay attention to the following points:

(1) for manual cleaning equipment, direct contact with the material should be removed completely.

(2) to a CIP or WIP device, consideration should be given to the problem of cleaning bearings.
