5 Expert PromptsPlease list the optimal jaw crusher settings (e.g., speed, gap width, jaw material) for processing granite with a Mohs hardness of 7, a compressive strength of 180 MPa, and a feed size of 200 mm, considering factors such as energy efficiency, production rate, and wear on the crusher plates. Provide supporting references or explanations for each setting.
For a grinding mill processing silicon carbide powder with a target average particle size of 10 μm, recommend the ideal grinding media composition, rotational speed, and slurry solid concentration to achieve a desired particle size distribution, taking into account the effects of over-grinding and re-agglomeration. Explain the theoretical basis behind your recommendations.
Describe the polishing machine setup and parameters required to achieve a mirror finish on a brass surface with a specified surface roughness (Ra) of 0.05 μm, using a 15-micron aluminum oxide polishing wheel and a coolant system. Provide the optimal polishing motion (e.g., rotational speed, direction, vibration) and explain how to maintain the required surface finish during the polishing process.
Compare the performance of a ceramic and a rubber grinding media on a mill processing calcium carbonate powder from a 100-μm diameter feed, with the goal of producing an average particle size of 20 μm. Consider the effects of grinding energy, grinding time, and wear on the grinding media. Discuss the trade-offs between media durability, grinding efficiency, and surface roughness.
Given a specified polishing compound material (e.g., cerium oxide, colloidal silica) and a desired surface finish (e.g., Ra = 0.1 μm), design an efficient polishing sequence (e.g., multiple steps, intermediate cleaning, and inspection) to achieve the target finish on a complex surface (e.g., curved or angular) without inducing micro-cracking or surface defects. Discuss the effects of polishing pressure, temperature, and vibration on the final surface finish.
