For over 100 years the company Loesche has been building vertical roller grinding mills for grinding: • Coal • Cement raw material • Clinker / granulated slag • Industrial minerals, and • Ores The core elements of these plants are the Loesche vertical mills for dry-grinding the above-mentioned grinding stock.
DetailsIn modern roller mills, there is an airflow that carries fine particles away from the grinding zone. A high production capacity can be achieved due to this fact, but the particles being removed usually have a broad size distribution. Today, ball mills are gradually giving way to roller mills in the manufacturing of cement and other dry mortars.

DetailsDepending on the abrasiveness of the material to be ground and areas to be protected, different wear materials are used on our vertical roller mills. The grinding elements are primarily made of alloy cast iron as per DIN 1695, hardfaced cast iron or composite materials with high-chromium inserts in ductile base materials.
DetailsRoll grinding elements, roll technology. The movement mode of roll grinding is determined by the force of the finished roll movement. There are four major elements: roll speed, grinding wheel speed, Z-axis speed, and X-axis feed. Their relationship: 1. Rotation speed of roll: Determined with the radial velocity of 0.8-1. 2m/s.
DetailsPre-cutters, Crushers & Shredders Size reduction of lumpy materials at high throughput rates. PALLMANN manufactures Pre-cutting mills, Shredders, and Chippers for the size reduction of lumpy materials at high throughput rates; this allows further processing such as dosing, fine grinding, agglomeration, or facilitates the transportation, mixing or storage of the material.
