Abstract
A process for grinding and processing kaolin sand and powder by a ball crusher. The kaolin clinker of 1-8mm is ground in a ball crusher to form a sand-powder mixture, and the mixture is lifted to a powder selecting machine by a bucket elevator. Under the separation action of the powder separator, sand is separated from the lower part of the powder separator, and powder is collected by a back-stage fan negative-pressure suction bag type dust collector, so that the aims of grinding kaolin clinker, separating sand and powder products are fulfilled.
Description
Technical Field
The invention relates to a process for grinding and processing kaolin sand and powder by a ball crusher, belonging to the technical field of non-metal mineral processing.
Background
The existing kaolin sand and powder processing is realized by respectively arranging production lines. The sand material is processed by crushing the clinker by a crusher and then screening the crushed clinker by a linear sieve in a grading way, so that the process system is complex, the particle size distribution is poor and the yield is low; the powder is processed by adopting a traditional Raymond mill mode, so that the equipment consumption is extremely high, and the yield is low. By combining the factors, the traditional kaolin sand and powder processing technology has lower production efficiency and higher production cost.
Disclosure of Invention
In order to overcome the defects of complex processing technology, lower production efficiency and higher production cost of the existing kaolin sand and powder, the invention provides the process for grinding and processing the kaolin sand and powder by the ball crusher, and the process has the advantages of simple system, reliable operation, higher grinding efficiency, reasonable particle size distribution and lower production cost.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a process for grinding and processing kaolin sand and powder by a ball crusher comprises the ball crusher, a lifter, a powder concentrator, a dust collector and a fan; the ball crusher, the hoister, the powder concentrator, the dust collector and the fan are arranged from front to back. The elevator is provided with a feeding port corresponding to a discharging port of the ball crusher, the discharging port of the elevator corresponds to a feeding port of the powder concentrator, powder in the powder concentrator is sucked into the dust collector from the upper part under the negative pressure action of the fan and collected, sand is settled in the powder concentrator and discharged from the lower part, and therefore separation of the sand and the powder is completed.
Preferably, the elevator is a bucket elevator.
Preferably, the dust collector is a bag type dust collector.
Preferably, the kaolin raw material is 1-8 mm. The ball crusher grinds kaolin raw materials with the particle size of 1-8mm to form sand-powder mixture, the mixture enters the powder concentrator through the elevator, the sand material and the powder material are separated under the centrifugal force action of the powder concentrator, the defect that production lines need to be respectively arranged for the traditional sand material and powder material is overcome, and the production line is simplified.
The invention has the beneficial effects that the ball crusher is adopted to grind the kaolin clinker with the particle size of 1-8mm, one production line can simultaneously produce sand and powder, and the effects of replacing the traditional crusher to produce sand and Raymond mill to produce powder are achieved. And moreover, the grinding process of the ball crusher is adopted, the efficiency is far higher than that of the traditional process, and the production cost is lower.
Drawings
FIG. 1 is a schematic view of a production line of the present invention.
In the figure: 1-ball crusher, 2-bucket elevator, 3-powder concentrator, 4-bag type dust collector, 5-blower, A-raw material, B-sand material, C-powder material and D-negative pressure.
Detailed Description
Referring to fig. 1, a process for grinding and processing kaolin sand and powder by a ball crusher comprises a ball crusher 1, a bucket elevator 2, a powder concentrator 3, a bag type dust collector 4 and a fan 5. After entering a ball crusher 1, a kaolin raw material A with the thickness of 1-8mm is directly ground into a sand-powder mixture. The mixture flows into the lower part of a bucket elevator from a discharge port of the ball crusher, is lifted to the upper part by the bucket elevator 2 and is input into a powder concentrator 3, and the mixture is separated into sand B and powder C under the centrifugal force action of the powder concentrator 3. The powder C is sucked into the bag type dust collector 4 from the upper part and collected under the action of the negative pressure D of the fan, and the sand B is settled in the powder concentrator and discharged from the lower part, so that the separation of the sand and the powder is completed, and a perfect process production line of the kaolin sand and the powder is formed.
