The Limestone High Pressure Roller Mill features a simple structure and reliable performance, making it ideal for fine and ultra-fine crushing. It controls the fineness modulus effectively. Huashengming designed this mill with the market's demand for crushing hard materials in mind. Compared to other high pressure roller mills, this model significantly boosts crushing capacity. It works well for hard and medium-hard materials with compressive strength below 250MPa and humidity under 10%. These materials include river pebbles, coke, coal, ceramic raw materials, quartz, limestone, shale, chalk, bricks, slag, clinker, feldspar, gypsum, salt, and other solid materials.

The main body consists of two rollers that rotate in opposite directions. The conveying equipment feeds brittle material into the weighing bin, which contains a weighing sensor. The feeding device then moves the material into the gap between the two rollers. The rollers pull the material into the gap, where they press it into a dense material cake. The material cake falls from the gap and exits through the discharge hopper, where the conveying equipment carries it away. In the next stage, the material cake undergoes further dispersion or grinding.

Product features of limestone high pressure roller mill

1. The hydraulic system makes it easier to adjust the roller gap: while protecting the safety of the whole machine.
2. The high pressure roller mill uses alloy steel inlaid carbide stud roller surface or high manganese steel integral casting roller surface and fan-shaped roller surface, which greatly extends the service life of the roller surface, and the high output can reach more than 20,000 hours.
3. The manganese steel roller surface has high economic efficiency in the field of cobblestone.

The limestone high-pressure roller mill produced by Huashengming Heavy Machinery Factory can also be used in mineral processing, electric power, chemical industry, cement, refractory materials, abrasives, construction and other industrial sectors to crush various high and medium hardness ores, rocks, industrial waste slag and other single raw materials or mixed raw materials mixed with clay. It is especially used in the production of melon stone, coal, coal gangue and other products in the construction materials and electric power industries. It has better effects than general high-pressure roller mills and can also be widely used in the crushing steel sand industry.
