鉱山設備ガイド：What Equipment Should You Use for Stone Factories, Cement Plants and Coal Preparation Plants? A Complete Guide to Efficiency Energy-saving Box Crushers, Roller Crushers and Heavy Hammer Crushers

The high-efficiency and energy-saving box-type stone crusher is specially designed for crushing medium-hard brittle materials, such as limestone and coal. The maximum compressive strength of the materials to be crushed does not exceed 150 kg/cm². It is mainly used in highways, railway stone production, cement, mining, coal preparation, power generation, chemical, and building materials industries. It is especially suitable for stone plants with a production capacity of less than 300 cubic meters per day, featuring compact structure, reasonable process, low investment, and high economic efficiency. The double-roll crusher is reliable in operation, easy to maintain, and has low operating costs. The discharge particle size is adjustable, and depending on the number of rolls, it can be divided into double-roll crushers and four-roll crushers. It can be widely used in the cement, metallurgy, chemical, power, coal, and artificial sand-making industries for processing brittle and tough materials. The heavy hammer crusher is developed based on more than twenty years of stone production experience and integrates the advantages of similar crushers. It features high output, low energy consumption, simple structure, and convenient maintenance. Why choose these three pieces of equipment? 1. The box-type crusher is designed for stone plants with a production capacity below 300 m³/day, with a compact structure, low investment, and high economic efficiency. 2. The double-roll crusher is reliable in operation, easy to maintain, has low operating costs, and adjustable discharge particle size, suitable for brittle and tough materials. 3. The heavy hammer crusher has high output, low energy consumption, simple structure, and easy maintenance, suitable for large-scale stone crushing. 4. All three types of equipment are widely used in cement, mining, coal preparation, power generation, chemical, and building materials industries, covering different requirements from coarse crushing to fine crushing. These three pieces of equipment are mainly used in highway and railway stone processing, raw material crushing in cement plants, mining operations, coal crushing in coal preparation plants, fuel preparation in power plants, raw material crushing in chemical plants, aggregate production in building material plants, and artificial sand production lines. The target users of these three types of equipment include stone and sand aggregate producers, cement plant equipment procurement and maintenance departments, mining companies, coal preparation and power plant equipment procurement departments, equipment maintenance departments of chemical and building materials enterprises, EPC contractors for crushing production lines, equipment distributors and stockists, and purchasers for overseas infrastructure and mining projects. Under what circumstances should these three types of equipment be chosen or replaced? If a stone plant has a production capacity of less than 300 m³/day and requires compact and low-investment crushing equipment, the box-type crusher is preferred. For handling brittle and tough materials, adjustable discharge particle size is required, preferably a counter-roller crusher; For large-scale crushing of stone and requiring high output and low energy consumption, a heavy hammer crusher is preferred; Old crushing equipment is severely worn, insufficient processing capacity, or finished product particle size does not meet standards and needs to be replaced; New stone or cement production lines require coarse or medium-fine crushing equipment. How to choose these three types of equipment? Step one: Confirm the material properties: box crushers are suitable for medium-hardness brittle materials such as limestone and coal; counter-roller crushers are suitable for brittle and tough materials; heavy-hammer crushers are suitable for medium-hard materials like limestone; Step 2: Confirm feed size: box crusher feed 500-1000mm, counter-roll crusher feed particle size ≤25-≤30mm, hammer crusher feed ≤600-≤1200mm; Step 3: confirm discharge particle size: box crusher discharge 0-100 to 0-550mm, counter-roll crusher discharge port 2-10mm, hammer crusher discharge particle size adjustable; Step 4: confirm processing capacity: box crusher 40-850t/h, roll crusher 5-110t/h, heavy hammer crusher 100-1200t/h; Step 5: Confirm motor power, select the corresponding power based on processing capacity and material hardness; Step 6: Confirm the installation foundation. All three types of equipment must be installed on a solid concrete foundation, secured with anchor bolts. Step 7: Confirm the material of wear parts. Select high-manganese steel, high-chromium cast iron, or alloy steel based on material abrasion. Step 8: Confirm environmental protection and automation configurations, which can be equipped with dust removal systems and central control systems.
