18.5kw - 800kw Sand Making Machine Quartz Stone Ball Mill Sand Machine

ball mill sand machine

Working Principle

•  
• The material is evenly fed into the first chamber of the mill through the feeding device and the hollow shaft at the inlet. There are stepped liners or corrugated liners in this chamber, and steel balls of different specifications are installed inside. When the cylinder rotates, the centrifugal force generated will lift the steel balls to a certain height and then let them fall, which will cause heavy impact and grinding on the material.
• After the material is roughly ground in the first chamber, it enters the second chamber through the single - layer partition plate. There are flat liners and steel balls in this chamber, which will further grind the material. The powder is discharged from the grid plate to complete the grinding and sand making process.

Product Features

• Wide range of applications: It can be used in the fields of sand making, mineral processing, building materials, etc. It can process various metal and non - metal materials, such as ores, gold, silver, copper, iron, cement, fertilizers, silicate products, etc.
• Fine and uniform discharge particle size: The discharge particle size is generally between 0.074 - 0.89mm. It can produce fine sand materials with uniform finished products and few acicular materials, which can meet the standards of construction sand.
• Power - saving: Compared with the old - type equipment, it can save more than 40% of power. The product particle size is relatively uniform, and the proportion of coarse particles and over - ground slime is small.
• Large processing capacity: The equipment has obvious advantages in continuous operation, and its production capacity ranges from 0.65 - 615 tons per hour, covering the operation requirements of large, medium - sized and small - sized production lines.
• Reasonable structure design: The hollow shaft is made of cast steel parts, the inner liner is removable, the large - diameter rotary gear is processed by casting and hobbing, and the inner part of the cylinder is inlaid with wear - resistant liner plates, which has good wear - resistance. It retains the end - cover structure form of the ordinary mill, and has a large - diameter inlet and outlet, with a large processing capacity.

Technical Parameters

• Feed particle size: Generally less than or equal to 20mm or 25mm, specifically depending on the model.
• Discharge particle size: Usually between 0.074 - 0.89mm.
• Ball - loading capacity: According to different equipment models, the ball - loading capacity varies from 1.5 - 338t.
• Cylinder rotation speed: The rotation speed of the cylinder varies for different models. For example, the rotation speed of the Φ900×1800 model is 37r/min, and the rotation speed of the Φ1830×3000 model is 24r/min, etc.
• Power: The power range is wide, from a dozen kilowatts to several hundred kilowatts. For example, the power of the Φ900×1800 model is 15kw, and the power of the Φ3200×4500 model is 800kw.
• Processing capacity: The output is 0.65 - 615 tons per hour. The hourly output of small - scale equipment may be less than a few tons, and the hourly output of large - scale equipment can reach hundreds of tons.

Application Areas

• Sand - making industry: It is used to produce construction sand, machine - made sand, etc. It can provide finished sand with reasonable gradation, round particle shape and controllable powder content.
• Mineral processing field: It grinds various metal ores to facilitate the subsequent separation operations and improve the separation efficiency.
• Building materials industry: It processes cement clinker, quartz stone, refractory materials, etc. to provide the required raw materials for building materials production.

Maintenance

• Daily maintenance: Regularly check the wear of each component of the equipment, such as the liner, grinding balls, hollow shaft, etc. Clean the sundries and dust inside the equipment in a timely manner, and check the lubrication of each lubrication point to ensure the normal operation of the equipment.
• Regular maintenance: Conduct a comprehensive maintenance of the equipment at regular intervals, including replacing the severely worn components, repairing and adjusting the transmission components, and checking the performance of the motor and the electrical control system, etc.
