The growth in demand for grinding mills

The growth in demand for size reduction equipment is not surprising considering the number of industrial applications that require size reduction operations. There is no dearth for grinding mills in South Africa for sale in the market since raw materials often occur in sizes that are too large to be used in production processes which requires their size to be reduced accordingly.

However, no single grinding machine can perform all the processes required in grinding particularly in instances when the material is either too hard or brittle. Size reduction in food processing can be divided into two categories: solid and liquid. For solid materials the operations are called grinding and cutting while for liquid materials, the operations are emulsification or atomization.

The process of grinding and cutting

One of the most extensive applications of the grinding machines in the food industry is the milling of grains to make flour however, grinding mills for sale in Zimbabwe that can also be used for other products like grinding corn for corn starch, grinding of sugar and milling of dried fruits and vegetables. Cutting is an operation used to break down large sizes of food into smaller pieces for further processing particularly in meat and poultry processing. Cutting machinery is relatively simple as it consists of rotating knives in various arrangements. One issue however with cutting machinery is how to keep the knives sharp so that they can cut and not tear.

Some manufacturing processes benefit from a combination of complimentary small scale stone grinding equipment technologies. These two-way processes maximize the efficiency of the size reduction equipment. Grinding equipment can be divided as to crushers and grinders. When a uniform particle is crushed, the size of the particle will vary a great deal and as the grinding continues the particles will turn from relatively coarse to fine and even to dust if required.
