人工砂製造業界において、垂直軸衝撃破砕機、通称砂 making 機は、主要な砂製造装置として広く使用されています。砂 making 機の破砕方法には、「ロックオンロック」と「ロックオンアイアン」の2種類があります。しかし、多くの人はこれらの2つの破砕方法の違いをあまりはっきりと理解していません。この記事では、主に砂 making 機の2つの破砕方法とその比較について紹介します。

適用状況の比較

Generally, “rock on rock” crushing method is used for shaping and “rock on iron” crushing method is used for sand making.

The “rock on rock” crushing method is suitable for crushing abrasive materials with medium hardness and above, such as basalt, etc. During the crushing process, materials injected from the impeller impacts the material liner and do not directly contact the metal components of sand making machine, reducing iron consumption and thus reducing maintenance time. The shape of the finished products is good under the crushing method of "rock on rock".

The “rock on iron” crushing method is suitable for crushing abrasive materials with medium hardness and below, such as limestone, etc. Under the “rock on iron” crushing method, sand making machine has high efficiency.

2 crushing methods of sand making machine

製砂機 (also known as "Sand Maker") have two feed modes – "feed at center" and "feed at center & sides". Generally, “feed at center” feed mode is used in “rock on iron” crushing method. In this condition, the vertical shaft impact crusher is used for sand making and has low production capacity. “Feed at center & sides" is used in “rock on rock” crushing method. In this condition, the vertical shaft impact crusher is used for shaping and has high production capacity.

主要な耐摩耗部品の比較

Sand making machine with “rock on rock” crushing method and sand making machine with “rock on iron” crushing method has different main wear-resistant parts.

Under the crushing method of “rock on rock”, materials form a material layer around the impact block and the materials impact on the material layer and are crushed. So, the main wear-resistant part of sand making machine with “rock on rock” crushing method is impact block.

「ロック・オン・アイアン」破砕方式では、衝撃ブロックをリムガードプレートに置き換え、材料は直接リムガードプレートに衝突して粉砕されます。したがって、「ロック・オン・アイアン」破砕方式を採用した沙子製造機の主要な耐摩耗部品はリムガードプレートです。
