Sand mill

  Sand machine also called sand making machine or crushing machine are all made of ore in line with the construction of aggregate equipment in general, sand machine for pebbles, gravel, limestone, quartz stone, marble, silica, shale, basalt, granite and other ore crushing operations, the particle size can be controlled and adjusted, the product size can be controlled below 5mm, the common sand machine includes: crusher sand machine, impact type sanding machine, roller type sanding machine, hammer mill, composite sanding machine, double sanding machine, sand machine is the advent of these many years after. The test of the market, and get the excellent effect of sand sand equipment for the majority of customers praise.

（Counterattack type sand breaker）

Characteristics and technical parameters of various sanding machines：

Counterattack type sand breaker：Also called the third generation sand machine, sand machine or counter, is a kind of equipment with hammer impact to ore crushing operations, crusher sand machine has high work efficiency, low energy consumption, the advantages of product into prismatic rules.

Impact sand breaker：Also known as VSI sand machine is a vertical sand machine, mainly relying on high-speed rotation of the impeller, stone thrown out, stone collisions between each other and fine equipment.

Counter roll sander：Also known as double roll sand machine, it is mainly by two roller wheel ore extrusion and to achieve the effect of crushing equipment.

Hammer sander：The utility model is a device which drives the hammer head to rotate at high speed by the rotor, and strikes the feeding ore to achieve the crushing effect.

Compound sand breaker：The utility model relates to a sand beating device composed of a multilayer rotor and a hammer head, wherein the material is smashed by the rotating hammer head in the process of falling, and the grinding effect is achieved.

Double stage sand breaker：Also called double level without a sieve bottom sand machine, a sanding device consists of two layers of rotor and hammer, the material in the process of falling in the first crushing cavity by the hammer hitting crushing, and then enter the second cavity below the hammer hit by fine crushing, finally finished material is discharged.

  The above six kinds of sand grinding machine are market tested equipment, the discharge granularity is below 0.5 millimeters, the discharge granularity is controllable and adjustable, and it is the most ideal choice equipment for sand and gravel field.
