What is graphite electrode machining After calcination and graphitization, the size of the formed blank varies, sometimes bending and deforming to a certain extent, bumping or falling, and the surface is rough and uneven because of some fil


Main components of single-axis inertial vibrating screen The main components of the single-axis inertial vibrating screen are the screen frame and the single-axis inertial vibrator. The screen frame is mounted on the cylindrical spring or t

Definition of graphite electrode purity Purity is the percentage of the aggregate in the aggregate or powder of a nominal size that actually meets the size requirements. Definition of granular purity Granular purity is a work indicator for


There are two ways to operate the ball mill. Our company has a special storage warehouse and storage method to ensure the safety of graphite electrode storage 1. Continuous production, that is, continuous feeding from one end, continuous di

The main point of choosing a shredder The choice of crushing machinery should first be considered based on the strength and hardness of the material, the size of the block, the required crushing ratio and other factors. Hard material select

Roller crusher can crush various carbon materials The roller crusher is a crushing machine mainly used for crushing or fine crushing in a carbon plant, and can crush various carbonaceous raw materials. Working part of the double-tooth rolle

Discharge amount is inversely proportional to calcination quality The size of the calcination tank is fixed, and the time for the raw material to pass through the calcination tank is mainly affected by the discharge amount, and is related t

Cylinder dryer structure The cylindrical dryer structure is a tiltable, rotatable metal cylinder with different forms of baffles installed to increase the contact time between the material and the heat medium. Cylinder dryer deflector has 3

The difference between crushing and milling The crushing is to change the larger block material into smaller pieces or granular materials, and the grinding is to grind small pieces or granular materials into powdery materials. 5 levels of s

2 reasons for calcining petroleum coke rotary kiln The speed of movement of the raw material in the rotary kiln, the time of the raw material passing through the rotary kiln and the calculation of the filling rate in the kiln. 1 measure to

Rotary kiln structure It is mainly composed of kiln body, kiln head, kiln tail, support wheel, rim, retaining wheel, transmission device, sealing device, fuel nozzle and exhaust system. The rotary kiln body is a cylinder welded by steel pla

An important means of testing the degree of calcination Determination of the electrical resistivity of the calcined coke is an important means to test the degree of calcination. The change of resistivity of petroleum coke during calcination

Definition of calcination The high-temperature heat treatment of various solid carbonaceous raw materials under air-insulated conditions is called calcination. Calcination is an important process in the production of carbon products, and th

5 types of coking process There are two kinds of coking processes for early production of petroleum coke: 1. kettle coking, 2. flat furnace coking. At present, there are three commonly used production processes: 1. delayed coking, 2. fluid

Cylindrical nipple connection is more self-locking The self locking property of cylindrical nipple is better than conical nipple. We suggest you choose the cylindrical connector first. Self-locking force definition of nipple The self-lockin

Relationship between elastic modulus and stress The greater the modulus of elasticity, the greater the stress required to produce a certain degree of elastic deformation, or the less the elastic deformation produced under a certain stress.

Porosity definition Porosity refers to the percentage of the pore volume in the test block to the total volume of the test piece. From the perspective of macroscopic structure, various carbonaceous raw materials, charcoal products and graph

Product preheating temperature and warm-up time The preheating temperature and preheating time of the product have certain influence on the impregnation quality and the impregnation production cost. The insufficient preheating temperature w
