Ball Mill (ball grinding mill)
Ball mill after the material has been broken, and then the key equipment for crushing.
Ball mill is widely used in industrial production of one of the high-grinding machinery.
There are many types, such as the hand ball mill, horizontal mill, ball bearing, energy-saving ball mill, overflow-type ball mill, ceramic ball mill, ball mill, such as lattice.
Ball mill for grinding various ores and other materials, are widely used in mineral processing, building materials and chemical industry can be divided into two types of dry and wet grinding methods. Mine in different ways according to schedule, can be divided into type lattice and two types of overflow.
Ball mill after the material has been broken, and then the key equipment for crushing. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ore dressing of non-ferrous metals and ceramics and glass production industries, for a variety of ores and other materials Grindability dry or wet grinding.
of the test run:
Ball mill installation is complete, after passing inspection, commissioning can be empty. Commissioning of the mill should be in charge of skilled operatives to carry out the ball mill and ball mill to comply with safety rules strictly.
(A) the operation of air-time continuous operation of not less than 12-24 hours, operation should be found to solve the problem.
(B) Air test machine running a normal load can be carried out commissioning. Load test run should be carried out in phases. Load operation should be carried out nesting feeding, to avoid the ball and cylinder liner wear unnecessary loss and damage.
1, by adding the appropriate materials and 1 / 3 the number of balls (see the volume of the largest ball mill fitted total map) 12-24 hour test run.
2, by adding to 2 / 3 the number of 24-48 hours running balls.
3, ball marker in accordance with the situation, the production of qualified products by reference to the same concentrator mill volume of the actual loaded ball, ball mill and Taiwan to determine the reasonable amount of loading the ball to carry out step-by-step commissioning of less than 72 hours.
(C) The increase in load and commissioning of the length to the size of gear and gear reducer running situation (temperature rise, noise, tooth contact, etc.) to determine the basis. Tooth contact in accuracy did not meet design requirements for the former may not be functioning at full capacity.
(D) commissioning of cooling, lubrication system should be working correctly. Main bearings, transmission bearings, reducer temperature should be normal.
(V) into 2 / 3 the number of 24-48 hours after the test run ball should be checked and tightened all the bolts again.
(Vi) commissioning the work of the records to do a good job.
